RESUMO:

The use of bacteria in different cultivars has become an interesting alternative due to its cost-effectiveness, its efficiency in controlling phytopathogens and its contribution to increasing plant productivity. Thus, the application of plant growth-promoting bacteria is considered one of the main strategies for reducing the use of chemical fertilizers. Therefore, the present study evaluates the agronomic efficiency of different dosages and modes of application (via seeds, foliar application and combination of both modes) of the liquid form of inoculants based on the bacteria Bacillus subtilis, Azospirillum brasilense and Pseudomonas fluorescens in plants of calendula (Calendula officinalis L.) with regard to germination aspects of seeds and plant development. For this, the research was divided into two stages, the first being carried out at the Laboratory of Seed Technology and Matology (LaSeM) of the State University of Mato Grosso - UNEMAT, Campus of Alta Floresta - MT, with the analysis of seed germinability . While the second stage was carried out in the field, with the collection and subsequent evaluation of marigold plants aiming at studying the initial, vegetative and reproductive development of plants under the effect of growth-promoting microorganisms, being carried out at LaSeM. The data obtained were submitted to analysis of variance and the measures of the treatments compared by the Tukey test (5%) with the aid of the SISVAR and R software. The results obtained corroborate the use of the analyzed bacteria as biological agents to promote the growth of calendula.
