RESUMO:

Cotton (Gossypium L.) is one of the most important plants for the production of fibers, in addition to being a source of animal food and raw material for the production of oil from its seeds. The growing increase in cotton cultivation has led to the search for alternatives in order to express the maximum productive potential of the plants, however, increasingly influenced by concerns about the environment. For this, the use of biological products are alternatives that aim to increase productivity. Growth inducers tend to improve the growth and defense system of plants against abiotic and biotic stresses, being considered strategic in the search for sustainable agriculture. The objective of this work was to test different products based on resistance-inducing microorganisms in late sowing cotton in the 2021/22 harvest. The experiment was carried out on the private property on a farm located 35 km from the municipality of Sapezal, Estrada SZ 01, left bank. Seven varieties of cotton were sown and three types of products based on microorganisms were used, being a bacterium Bacillus amyloliquefaciens and two fungi of the genus Trichoderma. The experimental design consisted of a factorial experiment with combinations of 7 cotton materials and 3 treatments with applications of resistance-inducing microorganisms and control with 3 replications. The applications were carried out via foliar, 2 applications of each product in stages B4 and F1, with a CO2 backpack sprayer. The trial was conducted from March to July 2022. The following characteristics were evaluated: Plant height, number of first, second, and third position reproductive structures, number of abortions, productivity, and soil microbial activity based on the Basal Basal Respiration (RBS). The productivity result behaved differently in relation to treatments and varieties, in some cases the control treatment expressed higher productivity, not generating a significant difference between treatments.
