Abstract

The color common bean (Phaseolus vulgaris L.) is one of the most present foods on the Brazilian plate, and for this reason, it becomes a crop that demands attention to decrease spending on input costs and increase productivity per area. Some agricultural practices are necessary to decrease the costs in the producer's pocket, inoculation and co-inoculation are one of the ways to help in this regard, the bacteria are important to reduce the amount of fertilizer in the agricultural field, and, even so, make the plant grow healthy and have the same productivity. In view of this, Rhizobium tropici and Azospirillum brasilense are becoming more and more important for the productivity of the bean plant, together with the no-till farming system and the use of grassy stubble. The experiment will be conducted in Selvíria - MS, in a distrofic Red Latosol, sown at the end of April 2022, in randomized blocks, with 4 repetitions, in a 5x4 factorial design (combination of cover x inoculation factor). The objective is to evaluate the effects of mulches, intercropping and management of inoculation and co-inoculation of beneficial microorganisms (Rhizobium tropici and Azospirillum brasilense) in no-till systems already consolidated in the development and production of the bean crop in a cerrado region, with the hypothesis of observing whether previous crops in the area can interfere with the response of the bean.
