RESUMO:

Green manure is a technique that results in the improvement of the physical, chemical and biological conditions of the soil, protecting it from erosion, and contributing to reduce dependence on external inputs. Thus, it is important to identify species of green manure adapted in each region. In addition, the use of efficient microorganisms (ME) may potentiate the beneficial effect of the green manure technique. The objective of this study was to introduce and analyze biomass production by Crotalaria juncea (Crotalaria juncea), mucuna-preta (Mucuna aterrina) and bean (Canavalia ensiformes) under the conditions of Matias Barbosa-MG, to determine the effect of green agronomic characteristics of maize-green planted in succession, under no-tillage; and quantify the effect of the application of efficient microorganisms in cultivated area with green maize. This work was carried out in a family production system, in Sítio Irmão Coragem, between October 2016 and October 2017, in the municipality of Matias Barbosa (MG). A split plot scheme was used in the randomized complete block design with three replicates. The variables analyzed in the legumes were biomass productivity and macronutrient content. In the corn crop, the total weight of green peas was evaluated, the percentage of marketable debris, the dry mass of the corn straw, as well as its Nitrogen content. The corn cultivar used was AG 1051. The biomass yield values of legumes and green maize, as well as the percentage of tradable ears, are in agreement with the national average for each variable. These results demonstrate that the studied legumes show good adaptation to Matias Barbosa 's edaphoclimatic conditions. Regarding the results of green maize, the values found show that there was no response to green fertilization or to the use of microorganisms. This was probably due to the fact that the phytomass addition of the legumes during the first year of cultivation was insufficient to affect the characteristics of the green maize evaluated.
