Abstract

The cowpea bean (Vigna unguiculata (L.) Walp.) is the second most widely grown bean in Brazil and every day it is gaining new markets, and for this reason, it becomes a crop that requires attention to reduce spending on input costs and increase productivity per area. Some agricultural practices are necessary to reduce 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, Bradyrhizobium sp 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 grass-studded pastures. The experiment will be conducted in Selvíria - MS, in soil originally with cerrado vegetation, sown at the end of April 2023, in randomized blocks, with 4 repetitions, in a 5x4 factorial design (combination of cover factor x inoculation factor). The objective is to evaluate the effects of mulches, intercropping and management of inoculation and co-inoculation of beneficial microorganisms (Bradyhizobium sp and Azospirillum brasilense) in no-till farming system already consolidated in the development and production of the crop of cowpea in cerrado region, having as hypothesis to observe whether previous crops in the area can interfere with the response of the implemented crop.
