• Abstract:

  The use of microorganisms in agricultural production systems has shown potential for increasing productivity and optimizing cultivation costs in various crops. In this context, the present study aimed to evaluate the effect of different soil management practices, associated with the application of plant growth-promoting microorganisms (PGPM), on the productivity of soybeans, beans, rice, wheat, sorghum, and corn. The experiment was conducted in the experimental area of UNESP – Ilha Solteira, located in the municipality of Selvíria (MS), in a randomized block design with seven replicates. The treatments consisted of three types of management: conventional management, with seed treatment and inoculation, mineral fertilization, and chemical control of pests, diseases, and weeds according to the requirements of each crop; semi-organic management 1, with the application of half the recommended mineral fertilization, soil remineralizer (Brutal Rocks®),organic compost, MPCP (Brutal Plus®), and nutrients (Brutal Calcium® andUltrasal®);semi-organic management 2, similar to the previous one, but without the use of mineral fertilization. In semi-organic management, there was no chemical control of pests and diseases, with only herbicides being used for weed management. The evaluations performed were the grain yield of each crop and an economic analysis of each management system. The yield data were submitted to Tukey's test at a 5% probability, using SISVAR(®) software.The results indicated that, in semi-organic management systems, the plants presented similar health and agronomic performance to conventional management in terms of grain yield. In addition, a reduction in mineral fertilizer costs was observed. These data highlight the potential of using microorganisms associated with nutritional supplementation as a viable strategy for promoting more sustainable, economically efficient, and highly productive cropping systems.
