  • Adequate irrigation management is important to optimize this system, maximizing production, especially in intercropped systems, so that competition for water between crops does not occur. With this in mind, the use of intercropping comes as an alternative to reduce soil water evaporation and, consequently, greater availability of water for plants. Given the above, this work aims to optimize water resources for the cultivation of intercropped maize in the southwest region of the state of Mato Grosso. The work is divided into three chapters, in which the first aimed to test two models and two sizes of microlysimeters to determine soil water evaporation as a function of draining water or not. Soil water evaporation was determined using microlysimeters constructed of rigid PVC tubes. Two models of microlysimeters (with and without water drainage) and two sizes (100 and 150 mm in diameter) were tested. Two tests were performed in microlysimeters, submitted to an irrigation depth of 60 mm and then to 4 irrigation blades (15, 30, 45 and 60 mm). Soil water evaporation values did not show significant difference between sizes and models of microlysimeters, and were higher than those observed in weighing lysimeters. The microlysimeters tested in this experiment can be used to quantify soil water evaporation. The second chapter aimed to evaluate the influence of different sowing times of crotalaria in an intercropping system with off-season maize, on evapotranspiration, dual Kc values and productive characteristics of maize and crotalaria. Six weighing lysimeters were used, previously calibrated to determine the evapotranspiration of the single maize crop and with five times of crotalaria sowing between the rows. Weighing microlysimeters were used for the daily determination of soil water evaporation. With this information, the basal crop coefficient (Kcb) and the soil evaporation coefficient (Ke) were determined. The use of intercropping between maize and crotalaria at any time of sowing of crotalaria between maize rows reduced Ke values and increased Kcb values, that is, reduced soil water evaporation and increased plant transpiration. There was no competition for water in the cultivation of maize intercropped with crotalaria, when compared to the cultivation of single maize. It is possible to cultivate maize in an intercropping system at any evaluated sowing time of crotalaria. Finally, the third chapter aimed to evaluate the influence of different sowing times of crotalaria in an intercropping system with irrigated and non-irrigated off-season maize on the variability of soil moisture and temperature. The treatments consisted of different sowing times of crotalaria intercropped with the maize crop. The treatments were submitted to two environments, one under irrigation conditions and the other without irrigation. The irrigation system used was a sprinkler system with a uniformity coefficient greater than 80%, with an applied water depth of 10.38 mm h-1. To measure temperature and soil moisture, K-type thermocouple sensors and time domain reflectometry (TDR) probes were used, respectively. The intercropping of maize with crotalaria provides the soil with a smaller range of soil temperature, with higher values in an environment without irrigation compared to the irrigated environment. Soil moisture was lower in the treatment of maize in single crop.

  • Mostrar Abstract
  • Habitat loss from the expansion of agriculture is cited as one of the main threats to biodiversity. Agricultural landscapes are increasingly common, however, in these areas the processes and mechanisms related to the persistence of biological communities are still poorly understood. Thus, the prediction of how these communities respond to certain factors can be the basis for planning the conservation of remnants of native habitats and management practices in agricultural systems that are less aggressive. Insects in general are diverse, abundant and participate in important ecological processes for the maintenance of the ecosystem and services for humans. Therefore, they are good organisms for this type of studies. Among insects, beetles of the subfamily Scarabaeinae, “dung beetles”, (Coleoptera: Scarabaeidae) are indicators of changes in animal and plant communities and in ecosystem functioning, as, among other things, they are sensitive to physical and ecological changes in the habitat. The state of Mato Grosso, Midwest region of Brazil, is one of the largest producers and exporters of soybean (Glycine max L.), in which its cultivated area advances over the native vegetation in the Amazon, Cerrado and Ecotone (Amazon-Cerrado Transition). In view of this, dung beetles were collected with pitfall traps in 75 remnants of native vegetation, maintained in Legal Reserve areas, and in 99 adjacent soybean crops. First, we assess the impacts of converting native habitats into crops, identify which species are able to persist in these environments and which factors (amount of habitat, amount of pasture, time of land use as a crop and time since last grazing) influence this community; crops maintain a community distinct from that found in native environments; Pastures fields and the amount of habitats were good predictors of richness and similarity of composition, however, neither one of the variables studied has an influence on the abundance of dung beetles. Then, we analyze which factors (richness of native environment, NDVI, amount of habitat, amount of pasture and time of anthropic land use) affect the dissimilarity (beta diversity) of species composition; NVDI was the variable that most influenced the change in composition between communities and that there is a marginal effect of species richness in native environments. Therefore, our results suggest that the presence of more conserved native vegetation remnants (Legal Reserves) is important for maintaining the diversity of dung beetles in soybean growing environments, which, consequently, will favor the maintenance of functions ecological and services ecosystems.

  • Mostrar Abstract
  • Sunflower has a slow initial growth, which makes it very sensitive to weed interference, making it necessary to plan strategies to minimize the effects of these interferences. Therefore, the objective of this study was to identify the weeds present throughout the crop cycle and to evaluate and compare the effectiveness of herbicides applied in the control of weeds in the sunflower crop. The survey was carried out in three areas cultivated with sunflower at different stages of crop development (35 and 100 days after emergence). The square inventory method (0.25 x 0.25 m) was used randomly launched 160 times between the rows of the crop. The plants were identified according to species, popular name and family. Then, the following were calculated: frequency, relative frequency, density, relative density, abundance, relative abundance, importance value index, relative importance value index and similarity index of areas and times. Allied to this strategy, the use of pre-emergent herbicides to control weeds becomes essential, however, little is known about the selectivity of herbicides for the crop. To evaluate the effects of herbicides, a randomized block design was used, with treatments in a 4 x 2 + 2 factorial scheme, with four replications, in which the first factor represented the herbicides s-metalachlor (1920 g ai ha-1 ), sulfentrazone (600 g ai ha-1), flumioxazin (40 g ai ha-1) and trifluralin (1780 g ai ha-1), the second the two controls, one weeded and the other without application and without weeding, and the third two types of soil (sandy and clayey). The application of herbicides was carried out in pre-emergence of the crop, using a CO2 pressurized back sprayer. Phytotoxicity evaluations of sunflower and weed control plants were carried out at 7, 14, 21 and 28 days after emergence. At full flowering of the sunflower, height and stem diameter were determined. After the physiological maturation phase, the head diameter, weight of a thousand achenes and yield were quantified. It was found that the most representative species in the studied areas were Bidens pilosa and Euphorbia hirta with a relative importance index higher than 15% in both periods evaluated. When weed control was not carried out, there was a reduction of up to 10.3% in productivity. The herbicides s-metalachlor, flumioxazin and trifluralin showed the best weed control. There was no effect of phytotoxicity on the crop, which is due to the low rainfall during the test.

  • Mostrar Abstract
  • There are more than 100 pineapple cultivars, however, only about eight are commercially cultivated, with the Smooth Cayenne cultivar being the most cultivated worldwide. In Brazil, production is distributed firstly by the Pérola cultivar and later by Smooth Cayenne. However, new cultivars have not been commercially launched. Since the use of these cultivars by producers has been low in the country and they need to be evaluated regarding adaptation and productivity so that they can be indicated to rural producers, the objective of this work was to evaluate the productivity and quality of fruits of cultivars of pineapple. Experiment one was implemented in May 2018. The experimental design used was in randomized blocks, with five replications and 20 plants per plot and spacing of 120x40x40cm. The cultivars evaluated were Pérola, BRS Imperial, Jupi, BRS Vitória, Smooth Cayenne, IAC Fantástico, BRS Ajubá and Gigante de Tarauacá. It could be observed that, despite the improved cultivars BRS Imperial, BRS Vitória and IAC Fantástico being resistant to fusariosis, not having thorns and having good qualitative characteristics, they had very low fruit mass. In turn, the cultivar BRS Ajubá stands out, which despite having good qualitative characteristics, being resistant to fusariosis and not showing thorns, obtained a good mass of fruit, being considered a good option for producers. The cultivars BRS Imperial, BRS Ajubá and IAC Fantástico are the most attractive to the consumer from a sensory point of view, due to their appearance, flavor and ideal sweetness. In addition to being resistant to fusariosis and not having thorns, characteristics that benefit rural producers.

  • Mostrar Abstract
  • Pineapple is a much appreciated fruit and has been standing out among several fruit trees grown throughout the country. Pineapple consumption is almost 60% in natura, and it is estimated that in the months of October to March it is the one with the highest consumption, in relation to the other months. For fresh consumption, it is essential that the fruit has an adequate size and characteristics such as sweetness for the consumer, where it will consequently achieve better prices on the market. Therefore, the objective of this work was to evaluate the occurrence of natural and artificial induction on the characteristics of three pineapple cultivars and to verify the behavior of eight cultivars against the cold, in order to identify a more tolerant cultivar to the induction of natural flowering. The experiment was carried out in the fruit growing experimental area of the State University of Mato Grosso - Unemat, in Tangará da Serra - MT. In both experiments, the design used was randomized blocks. In experiment 1 it was a 3x2 factorial (cultivars x flowering induction), and the evaluated cultivars were Pérola, Jupi and Gigante de Tarauacá. And for experiment two, the cultivars Pérola, BRS Imperial, Jupi, BRS Vitória, Smooth Cayenne, IAC Fantástico, BRS Ajubá and Gigante de Tarauacá were evaluated. The cultivars were left to induce naturally, being evaluated weekly from May to September 2019. In experiment one, for the vegetative characteristics leaf width D and number of active leaves, there was a significant difference at 1% probability and for plant height and leaf length D, there was a significant difference at 5% probability. In experiment two, the cultivars showed a difference for the percentage of naturally induced plants (PPI). The cultivars BRS Imperial and Smooth Cayenne had 0% of induced plants and the cultivar IAC Fantástico had 9%, while the cultivars BRS Ajubá and BRS Vitória had 32 and 31% of induced plants respectively and the cultivars Gigante de Tarauacá, Jupi and Pérola had 100% of the plants naturally induced. It is concluded that with the plant at the proper size, natural flowering does not reduce fruit size and the cultivars Smooth Cayenne, BRS Imperial and IAC Fantástico were tolerant to natural induction of flowering.

  • Mostrar Abstract

  • Information and Communication Technology resources are part of people's daily lives, present today in the most different areas. Common in urban areas is gradually extending to rural areas, where, for a number of factors, it mainly serves larger producers. In this sense, producers classified as family members, who are usually small producers, need the support of institutions commonly linked to the public sphere, whether municipal, state or federal, for their provision. This article sought to evaluate, through a semi-structured questionnaire, the Direto da Roça MT platform (www.diretodarocamt.com.br), an initiative of this type of resource offered through the MT Horticultura program, an extension project from UNEMAT – University of the State of Mato Grosso. The platform is a virtual shop window with the objective of displaying products and producers on the internet, in a way that helps as a new sales channel bringing the producer closer to the consumer. The main results obtained were indicators of the platform's efficiency and its contributions to producers, as well as the need for structural adjustments.

  • Mostrar Abstract
  •  

    Brazil, despite being the world's largest producer of passion fruit (P. edulis), with 602,651 tons in an area of 43,248 ha-1, has an average productivity considered low, around 14.1 t ha-1. This low productivity is mainly attributed to climatic factors, diseases and cultural treatments. Thus, it is important that new technologies are incorporated into this culture, which represents an excellent source of income for producers, especially in the family farming segment. Thus, the objective of this work was to evaluate the growth and development of passion fruit in different cultivation environments. The experiment was carried out in the experimental area of the State University of Mato Grosso - UNEMAT. The experimental design was in randomized blocks, in a 2 x 2 factorial scheme (cultivars x growing environment) with four replications and five plants per plot. The experiment was conducted using two cultivation environments. Environment 1 was implemented in an open field and environment 2 in an arc-type agricultural greenhouse, 7 m wide by 20 m long, with sides 3.5 m above ground level and a central arch of 5 m. The polyethylene used in the roof has a thickness of 120 microns and the sides with a thermo-reflective screen 50%. The protected environment will be predominantly oriented in a geographic north-south direction. Environment 2 will be in the field, with the plant conduction system in the form of a vertical espalier, 2.5 m posts, with a spacing of 6.0 m with a number 12 smooth wire strand from 2.0 m from the ground. Fortnightly evaluations of plant height (AP), stem diameter (DC), number of leaves (NF) and number of days to prune the main stem (NDHP) were carried out, which were the number of days spent for the main stem of the plant to reach a height of 2.00 m, when the blunting was performed to break the apical dominance. Height measurements were taken with a measuring tape, taking the soil surface to its apex as a reference. Stem diameter was measured with a caliper at a height of 5 cm from the ground. For the absolute growth rate of plant height (TACAP) and stem diameter (TACDC) and percentage increment (PI), there was a significant effect for the environments and only TACAP and TACDC showed differences in cultivars, and there was no interaction between the treatments for the environment and cultivars. The highest growth rates occurred in the use of environment 1 (agricultural greenhouse) and cultivar 2 (FB300). Thus, the use of an agricultural greenhouse can improve initial growth and passion fruit performance.

  •  

    The large extensions of cultivated areas in Brazil often generate phytosanitary problems, which have increased the use of pesticides. Consequently, there is a concern regarding the potential for contamination that these compounds can cause in the environment, and the proposal of the Environmental Risk Index (ERI) serves as a tool for managing the environmental impacts of pesticides. In addition, the search for more effective management tactics, such as the use of pheromones, has been a promising technology that aims to reduce the deleterious effects of insecticides on the agroecosystem. Given these possibilities, the objectives of this work were: (i) to carry out an ERI based on the main insecticides used to control lepidopteran pests in the state of Mato Grosso; (ii) to evaluate in the field experimental formulations of the sex pheromone of Spodoptera frugiperda (Lepidoptera: Noctuidae), one of the main agricultural pests in the country. Data on the amount of insecticides consumed were collected from the Instituto de Defesa Agropecuária de Mato Grosso (INDEA) and their physicochemical characteristics were obtained from the Pesticide Properties Database (PPDB) of the University of Hertfordshire and from the Pesticide Properties Database (PPD) of the US Department of Agriculture. The ERI parameters used were: soil persistence, leaching, volatility, toxicological profile and recommended dose. Regarding the evaluation of the pheromone, field tests were carried out in soybean, corn and cotton crops during the 2020/21 harvest. Five treatments were evaluated, being two experimental formulations (F1 and F2), one commercial formulation (FC), virgin females as a positive control (CP) and hexane as a negative control (NC). The main insecticides used to control pests in Mato Grosso which had a total of 20,249,521.90 kg of active ingredients (a.i.), in which the main ones were ordered in descending order of environmental risk: malathion > methoxyfenozide > chloranthraniliprole > flubendiamide≥ beta-cyfluthrin> lufenuron≥ methomyl≥ bifenthrin> lambda-cyhalothrin≥ alpha-cypermethrin ≥ cyantraniliprole≥ permethrin≥ chlorfenapyr≥ chlopyrifos≥ profenofos≥ thiodicarb> indoxacarb≥ zeta-cypermethrin≥ cypermethrin≥ teflubenzuron≥ spinetoram> triflumuron≥ acefate. This last insecticide, despite being moderately toxic to animal life, had the lowest ERI due to low persistence, leaching and volatility. In general, all substances showed medium to very high toxicity levels, which is a worrying factor if they reach non-target populations, such as bees, fish and birds. As for the pheromone evaluations, the average capture in the soybean crop of F1 (26.86), F2 (19.14) and CP (30.6) did not differ from one another but differed from FC (41.66) and of CN (0.66) (p<0.5). In corn there was no statistical difference between the means collected in F1 (28.90), F2 (28.55), CP (30.75) and FC (25.05) (p>0.5). On the other hand, in cotton, F1 (6.95) and F2 (6.89) did not differ from each other, but differed from CP (19.60), FC (16.27) and CN (0.22) (p< 0.5). Considering the results presented, it is expected that the ERI contributes to risk management and decision making that cause less environmental impact. Added to this tool, the experimental formulations have the potential to be used in the monitoring of S. frugiperda, especially in soybean and corn crops, as they can indicate the most opportune moment to introduce control measures, aiming at optimizing management effectiveness.

  • Soybean is an oilseed with numerous consumption purposes, such as oil, milk, cheese, among others, becoming one of the main foodstuffs for Brazilian families as it is directly interconnected with the country's economy, this oilseed is extremely rich in protein, serving also for the elaboration of bran and animal feed. However, the expansion of this grain crop in Brazil has led to the increase of several pests, especially the brown stink bug, Euschistus heros F. This insect poses risks to crops as it affects the crop at various stages of development, mainly compromising the formation of pods, which causes losses of up to 30% in the productive capacity or even in the progress of the seeds. From this issue, the objective was: 1) to investigate the action of plant-based phytoinsecticides from the Piperaceae family as a possible alternative for the control of the brown bug; The bioassays were carried out in the laboratories of the Center for Agro-Environmental Research, Studies and Development (CPEDA) of the State University of Mato Grosso (UNEMAT), Professor Eugênio Carlos Stieler University Campus, and chromatography was carried out at the Natural Products and Ecology Laboratory Chemistry (LAPNEQ) of the Federal University of Paraná (UFPR). In the experiments, essential oils obtained from the leaves of three species of Piperaceae (Piper hispidum Sw., Piper marginatum L. and Piper aff. divaricatum G. Mey.) were tested. The leaves were dried in a forced air ow oven at 40 °C and ground until reaching low granulometry. The plant material obtained was extracted by hydrodistillation and water vapor dragging using the Clevenger apparatus for four hours. For the insecticide bioassays, eggs of the stink bug E. heros from farms established in the laboratory were used. Five different concentrations of essential oils of the three species of Piper (0.25%, 0.5%, 1.0%, 2.0% and 4.0%) and two control treatments, one with water and the other only, were tested. with acetone solvent, on pest eggs. All tests were kept in a BOD air-conditioned chamber at 25 ± 1°C, 14 hours photophase and 70% RH. It was observed that the three species studied showed insecticidal effects on brown stink bug eggs and lethal effect on hatched nymphs. Piper marginatum stood out among the plants studied, as it caused high inviability of pest eggs. 2) The second chapter evaluated the phytoinsecticide effect of essential oils from three species of the Piperacea family, on immature T. podisi. Bioassays were carried out before and after parasitism, with seven treatments and 10 repetitions each, in a completely randomized design. The treatments were two controls (distilled water T1 and acetone T2) and five different concentrations of essential oils of each species of Piper (0.25%T3, 0.5%T4, 1.0%T5, 2.0%T6 and 4.0%T7). It can be seen that the pre-parasitism experiment resulted in less emergence of parasitoids, compared to controls, as well as influenced the sex ratio; Unlike the post-parasitism experiment, with the exception of treatments T6 and T7 in which no parasitoid emergence was verified, for the three species of Piper surveyed, there was a decrease in the birth of T. podisi, however it did not affect the sex ratio. Presenting itself as a promising alternative as a low environmental impact phytoinsecticide.

  • Mostrar Abstract
  • Agricultural and livestock activities carried out in the Amazon region have been criticized in recent years, and the pressure for a production system that is less impactful to the environment is constantly growing. Many ranchers in northern Mato Grosso have faced serious problems with the degradation of pastures, causing large productivity losses. It is estimated that around 50% of Brazilian pastures are degraded, reducing productivity and animal support capacity, and consequentre placement of forage plants by invasive plants. The degree of competition and interference of invasive plants is related to the morphological and physiological characteristics of the weed community. In this scenario, many ranchers opt for the complete reform of the pasture, replacing the forage species, without first performing a complete and efficient diagnosis of the area and then applying the necessary control methods and the proper corrections of soil fertility, which ends up continuing the degradation processes. Therefore, performing an accurate diagnosis of the area, evaluating the levels of degradation and defining strategies for the recovery of degraded areas is fundamental for the advancement of a concise, efficient and sustainable system. To evaluate the initial weed and forage weeds in the initial phase of the crop at three levels of soil fertility. And to evaluate the selectivity and efficiency of pre-emergent herbicide control in pasture. Article 1 aimed to study the relationship of productive interference caused by the forest competition between the weed species Paspalum virgatum L. (grass - razor) and the forage species Panicum maximum cv. Mombaça, in three different levels of soil fertility. The experiment was conducted in a greenhouse at the University Campus of Alta Floresta - UNEMAT, with the substitute series methodology, with three levels of soil fertility, thus composing a 5x3 factorial scheme. The variables were evaluated at 60 DAE, being plant height, number of byes, and shoot dry mass. The data were analyzed using the graphical analysis method, constructing diagrams based on yields or relative and total variations. The competitiveness indexes, grouping coefficient and relative aggressiveness were also determined. This article describes the results of interference of the initial forest competition on the different levels of soil fertility. Article 2 was conducted in a rural property in Alta Floresta - MT, with the objective of evaluating the weed control efficiency of the herbicide atrazine, applied in pre-emergence on the initial pasture formation of the species Panicum maximum cv. Massai. The experimental design used was in ranges, with factorial 8 x 2 with three replications, being 48 plots of 5 x 6 m, where the treatments consisted of eight doses of the herbicide atrazine applied in pre-emergence in two planting systems, no-go and conventional. The variables were analyzed at 60 DAA, which were the presence of phytotoxicity, DM accumulation and height of Massai grass plants, and visual evaluation of weed control efficiency. The data were submitted to variance analysis with application of the F test. In this article, the results and discussions about herbicide control efficiency in initial pasture formation are described.

  • Integrated production systems and their impacts on the physical, microbiological characteristics of the soil and on productivity in the Brazilian Savannah of Mato Grosso. This research evaluated physical and microbiological attributes of the soil and also evaluated agricultural, livestock and forestry productivity in the property used as a research unit and analyzed state productivity averages as parameters. The property is located in the municipality of Campo Novo do Parecis - MT. For the physical and microbiological analyzes, five distinct areas were considered and different means of production, being Livestock crop integration - ILP, forest crop integration - ILF, livestock forest integration - IPF, conventional livestock - PC and crop under no-tillage - LSD. A sixth area was used as a witness since it is an area of native cerrado fragment, which has no apparent anthropization. The data obtained were subjected to analysis of variance and the means compared by the Scott-Knott test at 5% probability. From the results obtained it was found that for the physical attributes they were grounded in relation to the native area, where loss of quality is observed in all systems. Considering the biological attributes and the organic matter content of the soil it was identified that the uses caused an improvement or did not alter the microbilic quality of the soil. In order to analyze productivity, relative indicators (covering any type of property and any productive system) were used in previous studies developed by ESALQ and CEPEA. In the productivity analysis, it was possible to identify that the studied property, which works with an integrated production system, presented results above the state averages when considering the livestock and agriculture indicators for soybeans and corn, with results lower than the only for cotton growing. The property does not have productivity data from forestry production, so it was not possible to make this analysis

  • Mostrar Abstract
  • The central question of this research was to analyze the physical-chemical data of water quality in the Jauquara
    River Basin (BHRJ) for water use in irrigation and for human consumption, verifying that they are within the limits
    established by the literature. To this end, methodological strategies were adopted to be applied at 21 BHRJ collection
    points using the variables of Hydrogenionic Potential (pH), Electrical Conductivity (EC), Chloride (Cl-),
    Calcium (Ca2 +), Magnesium (Mg2 +), Potassium (K +), Sodium (Na +), Hardness (Dur), Bicarbonate (HCO3-),
    Phosphorus (P), Nitrogen (N) and Dissolved Oxygen (OD). Some of these variables were used to calculate the water
    quality indexes for irrigation, such as: the Kelly Index (IK), the Percentage of Soluble Sodium (PSS), the Hardness
    expressed in French Hydrotimetric Degrees (GHF), the Index of Permeability (IP), Magnesium Adsorption Ratio (RAMg)
    and Sodium Adsorption Ratio (RAS), and the classifications of these ratios were based on the existing literature. While
    the acceptable data for human consumption will be evaluated by Annex XX of Consolidation Ordinance n. 05 from the
    Ministry of Health. The statistical techniques used were the average, the maximum and minimum values, normality
    test by the Shapiro-Wilk methods and the Chi square test (X2) and multivariate analysis, namely Cluster Analysis
    ( AA) and Factor Analysis / Principal Component Analysis (AF / ACP). The results referring to the general analysis
    of BHRJ, reveal that AA has three predominant groups, and that of ACP three Main Components, in which the
    highlighted element were HCO3-, Ca 2+, Mg2 +, Dur and CE both in the dry and in the dry season. in the rain.
    In the irrigation analyzes, he observes that the means that had changes were in the variables K +, pH and RAMg,
    in addition to presenting low and medium risk of salinity (C1-C2) and low sodicity (S1). Therefore, this research is
    partially concluded that contamination of BHRJ is given by a set of environmental factors, whether these activities
    are anthropic and / or the dissolution of rock ions in water bodies.

  • Mostrar Abstract
  • Ecotones are important tools for conservation as they protect components from different ecosystems, contributing to regional diversification. In this study we analyzed:

    1) the composition, richness and abundance of anurans in the ecoregion of Chiquitano Dry Forest, southwest of the state of Mato Grosso and, 2) the responses of anurans in face of the effects of edge and matrix in a fragmented landscape. Data collections occurred in 21 forest fragments in the years 2002 to 2004 in the rainy and dry season, with 10-day campaigns in each fragment. In each fragment, six sets of pitfall traps were installed, with the first being placed in the pasture matrix, the second on the edge and the subsequent four every 50 meters in the fragments. Each set was built with five buried 24-liter buckets, 10 meters apart, interconnected by 80cm-high fences. 839 individuals of 24 species of anurans and eight families were captured. Physalaemus albonotatus (n = 172) and Rhinella margaritifera (n = 114) represented the highest abundances and also the highest frequency indices, occurring in 76.19% (n = 16) of the areas. Leptodactylidae with 13 species was the most representative family, followed by Microhylidae (n = 3 spp.), Bufonidae and Hylidae (n = 2 spp.) and Craugastoridae, Dendrobatidae, Odontophrynidae and Phyllomedusidae with only one species. The wealth represents about 19% of the anurofaunistic diversity of the state of Mato Grosso. The species in this study are mostly common in open phytogeographic domains and with greater environmental plasticity, with the composition of species from the Cerrado, Pantanal and surroundings being more similar than in the Amazon. The intense forest fragmentation in this part of the state may have led to the replacement of species with greater requirements by others with greater plasticity in terms of habitat use. Despite this, species frequently associated with forest environments such as Leptodactylus petersii, Lithodytes lineatus, Osteocephalus taurinus and R. margaritifera have also been recorded. In addition, we recorded species endemic to the Cerrado (Pristimantis dundeei) and this region (Proceratophrys strussmannae), reinforcing the importance of ecotonal areas for species conservation. Also, among the records, we present an updated map and the southernmost record of the geographic distribution of L. lineatus, as well as the use of habitat. To understand the influence of landscape change in this region, we analyzed the composition, richness and abundance of anurans in pasture matrix, edge and forest habitats, considering the seasonal factor (drought and rain). The richness among the habitats did not present significant differences in any analyzed station. Despite this, the matrix held only 6.44% of the total abundance, with an increase in this pattern following the gradient matrix-edge-forest interior during the rainy (R² = 0.27; p = 0.014) and dry season (R² = 0.30; p = 0.005). The lower availability of micro-habitats for shelter and reproduction, as well as higher temperature and lower humidity in the pasture matrix, are possibly responsible for these responses. Therefore, the conversion of native vegetation to pastures can constitute an important threat to anurans, thus requiring a closer look at this region.

  • Mostrar Abstract
  • Pineapple farming represents one of the most important fruit segments in Brazil, being among the three main fruits in production and value in fruit farming. However, there are factors that may influence its production and productivity, being the interference of weeds in the culture one of the most important. Therefore, this study aimed to identify the weeds present during the whole cycle of the pineapple crop in the field and to evaluate and compare the efficacy of herbicides applied in the control of weeds in the pineapple crop. The method used to perform the phytosociological survey of weeds in two areas cultivated with the pineapple crop at different times (120, 240 and 360 days after planting) was the inventory square (0.25 x 0.25 m) randomly cast 25 times between the rows of the crop. The plants were identified by species, popular name and family. Then, frequency, relative frequency, density, relative density, abundance, importance value index and importance value index were calculated. To evaluate the effects of the application in directed jet and total area of herbicides on the pineapple crop, the pearl cultivar was used, at 1,20 x 0,40 x 0,40 m spacing. The experimental design was that of randomized blocks, with treatments in a 9 x 2 x 2 factorial scheme, with four repetitions, in which the first factor represented the herbicides sulfentrazone (700 g i.a ha-1), diurom (3,200 g i.a ha-1), clethodim (144 g i.a ha-1), atrazine (3,000 g i.a ha-1), hexazinone+diurom (396 + 1,404 g i. a ha-1), s-metolachlor (1,920 g i.a ha-1), trifluralin (1,335 g i.a ha-1), pendimethalin (1,400 g i.a ha-1), the second one the two witnesses, one weeding and the other without weeding, and the third one two modes of application directed jet (with protection of the seedlings with napoleon hat) and in total area (without protection of the plants). The application of the herbicides was done 20 days after the planting of the crop, using a CO2 pressurized costal sprayer. In general, the species found exposed characteristics such as aggressive competition for resources such as water, light and nutrients, high seed production, rapid growth, irregular germination. Furthermore, the phytosociological survey of weeds in a single area or time of year does not represent the potential for infestation of these areas. Therefore, it was observed that the most important time for weed management in pineapple cultivation is close to 120 DAP, period in which there was the highest number of weed species. And the most expressive present in most indexes with high potential to infest the cultivation of pineapple were Euphorbia heterophylla, Ipomoea triloba, Chamaesyce hirta, Sida rhombifolia, Eulesine indica, Digitaria spp., Priva bahiensis, Bidens pilosa, Cenchrus echinatus, Urochloa decumbens and Rottboellia cochinchensis.

  • AGROECONOMIC PERFORMANCE OF BANANA FARTA VELHACO UNDER DIFFERENT PLANTING DENSITIES

  • Orientador : WILLIAN KRAUSE
  • Data: 06/04/2021


  • Mostrar Abstract
  • The banana stands out as one of the leading fruits in world agricultural production and trade. Brazil is the world's fourth largest producer of this fruit, accounting for about 5.8% of production. However, it is not known how much of this total corresponds to the varieties of the Terra (plane tree) group. In commercial crops the spacing used has been from 3.0 x 4.0 m (833 plants ha-1) to 3.0 x 2.0 m (1,666 plants ha-1). The modification of the management system with high density planting has proved to be profitable, reducing production costs due to higher yields due to the greater number of bunches harvested per unit area, providing favorable results to the farmer. Therefore, the objective of this work was to evaluate the productivity, fruit quality and profitability of the banana Farta Velhaco under different planting densities. The experiment was conducted in the experimental area of fruit growing at the State University of Mato Grosso - Unemat, in Tangará da Serra - MT. The experimental design used was randomized blocks, with four treatments and four replications. The treatments consisted of four double row row spacing, being 4.0x2.0x1.0m (3,333 plants ha-1), 4.0x2.0x1.5m (2,222 plants ha-1), 4.0x2.0x2.0m (1,666 plants ha-1) and 4.0x2.0x2.5m (1,333 plants ha-1). The plants were evaluated in the flowering phase, through the characteristics of plant height, circumference of the pseudostem, number of active leaves, percentage of increase in plant height and circumference of the pseudostem. The phenological characteristics correspond to the duration of the vegetative, productive and total cycle. At harvest, productivity was evaluated and after ripening the clusters, the quality of the fruits. In addition to these characteristics, the production costs and profitability of the banana crop during the entire crop cycle were determined. At flowering, it was found that the planting spacing did not influence the characteristics of the pseudostem circumference, number of active leaves, number of days from planting to flowering, percentage of plant height and pseudostem circumference. It only showed a significant difference for the plant height characteristic, where there was an increase in the height values, as the planting spacing was reduced. Regarding the total cost of production (CTP) estimated for the banana, it was R $ 19,727, 46 (1,333 plants ha-1) to R $ 31,744.66 (3,333 plants ha-1), with the highest CTP values in the denser planting, with 3,333 plants ha-1, thus requiring greater financial investment by the banana grower. However, at this stage of the research there is still no data on bunches production and fruit quality, so there is still no revenue, only costs.

  • Mostrar Abstract
  • The planning and management of water quality have been necessary for sustainable development because the
    scarcity of water resources is already a reality even in regions where they are considered abundant. The objective
    of this study was to evaluate the technical feasibility of using rainwater for rainwater irrigation in Tangará da
    Serra, MT. To this end, laboratory analysis, statistics and field research were performed with the application of a
    questionnaire to collect qualitative and quantitative data to classify the quality of water relating it to possible sources
    of chemical compounds measured, estimate the potential for saving drinking water and analyze the climatological
    water balance to determine the volume of rainwater reservoir required to meet this activity. The results showed that
    the concentrations of chemical compounds monitored in rainwater samples do not offer restrictions on its use for
    irrigation of species grown in the backyard of the buildings, that the local atmosphere can interfere with these
    concentrations, so it is recommended to discard the initial millimeters and that there is potential for saving 100%
    of potable water used for irrigation of the UA, if its use is replaced by rainwater. Furthermore, the required
    reservoir volume obtained from the questionnaire data is 310 liters, while the one obtained from the PET is 2,240
    liters. We conclude that these savings could be reversed in the implementation of a public policy that considers
    financial aid for the construction of rainwater catchment systems in low-income households in the municipality.
    Thus, if the reservoir is properly sized, in addition to generating savings in drinking water, it contributes to the
    preservation of the watershed of the Queima - Pé river that supplies Tangará da Serra - MT.

  • The so-called Local Productive Arrangement (APL) are business organizations that are integrated through the actors involved: producers, customers and government support agencies. The study aimed to analyze the organization of the Local Productive Arrangement of tropical flowers produced in Mato Grosso. The first step was to identify the situation of the local Productive Arrangement, characterizing the actors involved in the APL in the state of Mato Grosso. Following, the tropical flowers produced in the region are described. In this way, the research is characterized as field and documentary. Data were collected from government agencies, tropical flower producers and the IBGE website (Brazilian Institute of Geography and Statistics). The APLs are structured in an early stage of development format, since among the actors involved there is no effective integration. Producers receive support from government agencies such as SEAF (State Secretariat for Family Agriculture), EMPAER (Matogrossense Company for Research, Technical Assistance and Rural Extension) and the State University of Mato Grosso (UNEMAT). It is concluded that the production of tropical flowers is promising, since more than 12 qualities of tropical flowers in different species are produced. However, it is necessary to restructure the Tropical Flowers APL so that there is more organization  and that involves specific public policies for the consistent development of APLs and, thus, strengthen the tropical floriculture segment.

  • Mostrar Abstract
  • The yellow passion fruit (Passiflora edulis f. sp. flavicarpa) is the most produced passion fruit species in Brazil, wich is the largest producer and consumer of the fruit in the world. Brazilian orchards suffer from the attack of several diseases, including anthracnose (Colletotrichum spp.), a very aggressive disease that infects the entire aerial part of the plant. In view of the low efficiency of chemical control and the small progress in the genetic improvement of the species with regard to protection against this disease, resistance induction emerges as an alternative measure to be combined in the management of the disease. The products based on Acibenzolar-S-Methyl (ASM), citrus biomass (BMC) and Bacillus subtilis have been tested against several pathogenicities and them provided a significant increase in the synthesis of proteins related to pathogenicity. Therefore, the first paper aims to evaluate resistance induction as an alternative measure in the management of anthracnose in yellow passion fruit. The experiments were carried out in a protected culture in a completely randomized design, 6 inducers were used (ASM, Bacillus subtilis, ASM + B. subtilis, BMC, BMC + B. subtilis, pathogen) + additional control, with 3 replicates with 5 plants each. In each experiment a different species of Colletotrichum was used. The applications of the inducers were started at 57 days after transplantation and the plants were inoculated with the pathogen 24 hours after the application of the inducers. The collections for enzymatic dosage occurred at 24, 48, 72, 96 and 120 hours after the inoculation of the pathogen, the incidence was evaluated daily and the severity weekly after the application of the pathogen. The enzymes peroxidase, polyphenoloxidase, β-1,3-glucanase and phenylalanine ammonia-lyase were measured. Evaluations of the Chlorophyll Falker Index (ICF), plant height (AP), plant neck diameter (DC) and number of leaves (NC) were also carried out every two weeks. All inductors provided an increase in the content of the evaluated enzymes. Treatments containing ASM showed lower ICF. In the first experiment, the ASM treatment provided greater AP and greater NF. In the second experiment, ASM showed lower NF at the end of the evaluations. The inducers were efficient in promoting enzymes involved in the immune response, however, it was not possible to clearly estimate the protection promoted by them. The objective of the second article was to verify the protective action of inducers on yellow passion fruit on anthracnose. The experiment was conducted in a completely randomized design consisting of 7 treatments and 5 repetitions. ASM, Bacillus subtilis, ASM + B. subtilis, BMC, BMC + B. subtilis and the pathogen without application of inductors were used as inducers, as well as a control without application of inductors and without inoculation of the pathogen. Detached leaves were used, which were disinfected, sprayed with inductors (or sterile distilled water), challenged with C. brevisporum and C. truncatum and kept under controlled light and temperature. The severity of the disease, AACPS, germination, the formation of appressoria and the penetration of the pathogen were evaluated. The treatment composed by the combination of Bacillus subtilis and citrus biomass is the most suitable to compose the management of anthracnose in yellow passion fruit, as it promoted an increase in the activity of enzymes related to the defense of the plant without compromising its development, as well as providing an area below the disease severity curve lower than that of the inoculated control and other treatments without direct action on the pathogen.

  • The gradual increase in population requires that food production follow this evolution, however, in a sustainable way and in balance with the environment. The research aims to identify the environmental practices of livestock farming in properties in the Municipality of Nova Marilândia MT, and as a specific objective to estimate the costs of building terracing in one of these properties. The research is characterized by the descriptive type, quali-quantitative approach, and used the multi-case strategy. The collection instruments were semi-structured forms, interviews and on-site observation. Four producers who have livestock as their activity took part in the research. Initially, the environmental practices used in the management of livestock were identified, and in one of the properties, terracing was built and costs were raised. It was identified that most properties do not use sustainable environmental practices, however, they do some actions in a partial way and that comply with environmental legislation. Regarding the cost of terracing per km, the cattle-raiser considered it high, however, he stated that he has already noticed changes in the property in relation to pastures that are preserved for longer, reduced erosion and contributed to the conservation of the neighboring roads of the property. Another positive effect was that the property served as a model for other ranchers to start building terracing in their pasture areas.

  • Mostrar Abstract
  • Invasions of exotic species in Brazil are one of the factors that most negatively impacts biodiversity. Its existence generates threats and conflicts with native species, causing biological losses to the ecosystem. The Pantanal is one of the Brazilian biomes most threatened by the presence of exotic species in its aquatic ecosystems. In order to monitor biodiversity and use of the fishing resource, the Brazilian government has implemented a control system that uses the Declaration of Individual Fishing (DIFs), in the which each fisherman informs the species caught, the quantity (units and kilos), the locations and baits used. This study aims to investigate the occurrences of invasive fish species, reported in DIFs, and their possible environmental and socioeconomic effects in the region of the municipality of Cáceres in the Paraguay River Basin. In all, 4002 DIFs were evaluated from the years 2019 to 2020. Of the 35 species of fish registered, 10 are exotic (originating in the Amazon basin) were registered in 40 locations, totaling 6,410 kg. However, of the 10 species, only Tucunaré, had already been registered by researchers in the region. Our results indicate the need for actions to confirm the actual occurrence of these reported species and point to two possible scenarios: 1) If the occurrences are confirmed, monitoring, study of impacts on native species, management strategies and evaluation of the economic potential for tourist marketing and fishing. 2) If the records are errors in the IPR records, it is necessary to improve the system used and offer training so that fishermen fill out the guides correctly.

The experiment was conducted during two harvests (2017/2018 and 2018/2019), in the experimental area at the State University of Mato Grosso UNEMAT. The chemical characteristics evaluated were phosphorus (P), potassium (K) calcium (Ca), magnesium (Mg), hydrogen (H), aluminum (Al), sulfur (S), organic matter (MO), hydrogen potential (pH), cation exchange capacity (T), total organic carbon (T) and percentage of base saturation (V). The microbiological variables analyzed were carbon from soil microbial biomass (BMS-C) according to the fumigation method - extraction, basal soil respiration (RBS) and soil metabolic quotient (qCO2), microbial quotient (qMIC) and total organic carbon (COT). For the analysis of the physical characteristics of the soil volumetric humidity (Uv), gravimetric humidity (Ug), soil density (Ds), macroporosity (MaP), microporosity (MiP), total porosity (Pt), soil resistance to penetration (RP). Crop yield, seed yield (PRODC) and fiber yield (PRODF) in kg ha-1 and fiber yield (F). Related to the activation of pathogenic enzymes related to the plant, the enzymes Peroxidase and β 1,3 - glucanases were evaluated, while for the enzymes related to the soil, acid phosphatase and β-glycosidase were evaluated. In order to verify the effect of the use of biological fertilization and cover crops on quality indicators of soil cultivated with cotton, it is necessary to continue studies that view the performance of these factors on the indicators. Also needing a longer evaluation period to obtain knowledge related to the behavior of pathogenic enzymes resulting from the use of biological fertilizer, as well as in the productivity and quality of the cotton fiber, since in two cultivation seasons no direct influence of this management can be observed about them.

  • Mostrar Abstract
  • Brazil is a country with great diversity and continental dimension that provide heterogeneity in space and resources. However, Brazilian biomes have undergone changes mainly due to the impacts of human activities, and they may become irreversible because of suffering several anthropic actions. Water is the source of life and a central natural resource in all human activities, essential for the survival of living beings and the maintenance of life. In addition to being used in the production of goods and services, it provides ecosystem services essential to the preservation of life. However, even though Brazil is a country that holds 12% of all fresh water available in the world, a water crisis has started related to several anthropogenic actions on the planet, including the overuse of water. Not only agricultural activity is responsible for environmental degradation, but also urban occupation, harming water bodies with the destination of domestic and industrial sewage in rivers and streams, deforestation of native vegetation and grounding of springs for urban constructions. In this context, the research aimed to value the services and environmental costs of the Palmital Stream in Tangará da Serra - MT. The research was divided into two parts, the first of which sought to calculate the blue water footprint of four vegetable crops (lettuce, tomato, beet and cabbage) based on the collection of water from the Palmital Stream of Tangará da Serra - MT. The study was carried out in three productive cycles in a private property near the Palmital Stream that uses water for the production of vegetables. The calculation of PHA was performed based on the method of Hoekstra et al. (2011). The second aimed to calculate the replacement cost of riparian forest in the Palmital Stream of Tangará da Serra - MT. Initially, a Forestry Engineer was hired to guide which species should be planted and the materials needed for the recovery of the Palmital Stream forests. Then, the costs of equipment and services necessary for the recovery and maintenance of this area were raised. The results made it possible to verify that in the first cycle, the cabbage had a PHA of 126 liters / kg, beet at PHA was 145.50 liters / kg, lettuce was the crop with the lowest PHA, at 52 liters / kg and the tomato with PHA of 219.44 liters / kg. In the second cycle, tomato was the crop with the lowest PHA, 36.6 liters / kg, lettuce with PHA of 74.90 liters / kg, beet with PHA of 459.70 liters / kg and cabbage with PHA of 235.08 liters / kg. Regarding the recovery of the Palmital Stream, it was found that there is an area with an erosive process, an area with a clean field and a dirty field that need to be recovered. In addition, it was certified that 1,480 native seedlings were necessary, of which 1,105 were pioneer and early secondary and 375 late secondary.

  • Mostrar Abstract
  • The objective was to investigate the scientific evidence on health risks and diseases that affect farmers and to analyze how meteorological variability can influence hospitalizations for respiratory and cardiovascular diseases. An integrative literature review was carried out by consulting the electronic databases SciELO and Virtual Health Library indexed in the databases LILACS, MEDLINE, BDENF and IBECS. In the study of climatic variability and hospitalizations for respiratory and cardiovascular diseases in the municipality of Tangará da Serra - MT, data from meteorological elements were collected on the website of the National Meteorological Institute (INMET) and information on diseases on the website of the Department of Informatics of the Unified Health System (DATASUS), considering the period from 2008 to 2018. In respiratory diseases, all age groups, children from 0 to 9 years old and elderly people over 60 years were included; in cardiovascular, all age groups and elderly people over 60 years were applied. An analysis of the 11-year period (2008-2018) and each year was carried out separately. Pearson's parametric correlation test (r) was used, the correlations were submitted to significance analysis by Student's t test. In the review, five categories emerged, namely: health risks arising from the use and exposure to pesticides, health implications arising from tobacco farming, implications for mental health, health risks arising from extractive activities and illness of the farmer resulting from different exposures in the rural work. The risks to the farmer's health are comprehensive, according to the configuration of the work. As for the association between meteorological variables and hospitalizations for respiratory diseases, in the annual analysis significant correlations were found including all age groups, in the years 2008 and 2015 with coefficients between (r = -0.74) and (r = 0.69 ), with a significant association of moderate to strong, with the variables that most influence the number of hospitalizations being the temperature (minimum, maximum and average) and relative humidity (minimum and average); with children, correlations were also obtained in the years 2008 and 2015, with coefficients between (r = -0.77) and (r = 0.63), the variables that most influence the number of cases are: precipitation, temperature (minimum, average and maximum) and minimum relative humidity, with moderate to strong associations; with elderly people, correlations were found in the years 2009, 2012, 2013 and 2016, with coefficients between (r = -0.84) and (r = 0.70), with moderate to strong correlations, with the temperature (minimum , average and maximum), relative humidity (minimum, average and maximum) and precipitation, the variables that most influence the number of hospitalizations. With cardiovascular diseases, including all age groups, in 2008, 2012 and 2015 significant correlations were obtained with coefficients between (r = -0.65) and (r = 0.73), with significant associations being moderate to strong , so that the variables precipitation, temperature (average and maximum) are those that most influence the number of hospitalizations; with elderly people, correlations were found in the years 2008, 2009, 2012 and 2015 with thermal amplitude, minimum and average relative humidity, maximum and average temperature and precipitation, with moderate correlation strength, with coefficients between (r = -0.64) and (r = 0.64). The results demonstrate that the variability of meteorological elements also influences the increase or decrease in the number of hospitalizations for respiratory and cardiovascular diseases.

  • Soil cover is an agricultural practice that can offer several benefits to plants and soil, as it promotes the control of weeds, reduces water losses through evaporation, facilitates the harvest and commercialization of fruits, the product is harvested cleaner, with better quality and important in the improvement of the physical, chemical and biological conditions of the soil, where this practice is very important in the cultivation of flat tomatoes destined for the fresh market. Therefore, the objective of this work was to carry out productive and economic analyzes on tomato cultivars of determined growth, in different soil coverings, evaluating the effect of soil temperature and humidity, the production cost and the physical, chemical and biochemical quality of tomato fruits, aiming at the fresh market. The experiment was carried out in the field in a randomized block design under a factorial scheme with two determined tomato cultivars (Fascínio and Thaíse) and five soil cover managements (Soil without cover, plastic mulching, Sorghum, Capim Sudan and Milheto) with four replications. . The drip irrigation system was used, through which fertigation was also carried out. Production evaluations were carried out regarding soil cover management, physical, chemical, biochemical aspects of tomato productivity and production cost. Soil temperature and humidity were also evaluated throughout the cycle and at the end of total tomato production. As a result, considering biomass production, Millet was the one that produced the most, with a value of 9.10 t ha-1, followed by Sorghum, Sudan and spontaneous vegetation. As for the decomposition rate, Milheto and Capim Sudão had the lowest rates and, consequently, the longest half-lives. Total and commercial yields were influenced in isolation by soil cover and non-commercial yield by cultivars and soil cover. Covering with plastic mulching provided the highest total and commercial productivity with 110.50 and 74.44 t ha-1 respectively, and the other treatments did not differ. The management of soil cover influences the production and quality of tomato fruits, and the cultivar Fascínio tends to have a higher concentration of lycopene and β-carotene. The cultivar Thaíse showed greater thickness of the fruit wall in the treatments without cover and sorghum, with no difference between cultivars for the other coverings. The cultivar Fascínio presented the greatest thickness (13.98 mm) compared to the cultivar Thaíse (11.95 mm). Covering with plastic mulching provided the highest soil temperature in relation to treatments without cover, Sudan grass, sorghum and millet. The treatment without soil cover has the lowest thermal amplitude of the soil for the depths of 0.05, 0.10, 0.20 and 0.30 m. Tomato cultivation showed a high potential for economic expression for the study region, especially when using plastic mulching, where it presented a higher operating profit of R $ 138,875.76, followed by treatments with Sorghum (R $ 123,712.05), millet (R $ 117,825.25), without coverage (R $ 110,532.95) and Sudan grass (R $ 99,654.02), with the costs of manual operations (19.61%), tomato seed (9%) , fertilization (13.27%), plastic mulching (7.17%) and irrigation (19.80%) the highest expenses observed in their production in relation to the total operating cost (TOC).
