RESUMO:

The corn crop has been gaining importance each year and has ceased to be just a second crop to become an essential source of income for the economic gain of the producer. In the search for new technologies to improve crop productivity, the use of micronutrients has been sought, such as Molybdenum and the use of growth-promoting microorganisms such as fungi of the genus Trichoderma. The search for more sustainable technologies in agriculture involves verifying their impact on the soil and microbial activity has been used as an indicator of the impacts of cultivation systems on the soil. The research was conducted in the field at Fazenda Ke Soja in the municipality of Sapezal - MT, in the 2020/21 harvest, in order to evaluate the use of different doses of Molybdenum with and without the use of Trichoderma in the corn crop and the impact of these on the soil microbiota. The design used was randomized blocks, in a 4 x 2 + 1 factorial scheme, with 3 replications for each treatment. The treatments were composed by the combination of 4 doses of Mo (105, 210, 315 and 420 g of Mo ha-1) with and without Trichoderma and an additional control treatment without the application of Mo and Trichoderma. The following characteristics were evaluated: plant height, ear insertion height, stem diameter, ear length, ear diameter, number of grain rows per ear, mass of 100 grains, productivity, chlorophyll A, B and total. No significant difference was observed between Mo doses for all studied variables. Regarding the ear diameter, there was a difference between the levels of the factors and the control, with all the levels of the factors being superior to the control. Regarding grain yield and chlorophyll B content, the application of Trichoderma was superior to the non-application.
