EFICIÊNCIA DE DESSECAÇÃO, PRODUÇÃO DE BIOMASSA E RELAÇÃO C:N DO MILHO, CULTIVARES DE panicum maximum E FEIJÃO GUANDU EM MONOCULTIVO E CONSORCIADO

Abstract

The use of soil cover, through integrated systems, has demonstrated effectiveness in driving changes in soil properties, promoting greater grain production. However, there is still a need to investigate how different cultivation arrangements in these management systems can influence soybean productivity. Thus, this study aimed to evaluate desiccation efficiency, production and C:N ratio of forage biomass in different monoculture and intercropping systems. The experimental design used was randomized blocks with three replications. The treatments consisted of biomass: corn; tamani grass; kenya grass; zuri grass; pigeon pea in monoculture; corn intercropped with tamani grass + pigeon peas; corn intercropped with kenya grass + pigeon peas and corn intercropped with zuri grass + pigeon peas. The results showed that the highest biomass production was obtained in the triple intercrop with zuri grass. Corn in monoculture had a higher C:N ratio and pigeonpea had a lower ratio. The integrated systems contributed to increasing biomass production and balancing the C:N ratio, promoting greater soil coverage and nutrient cycling. We conclude that integrated systems, which combine the cultivation of grasses and legumes, are an innovative and efficient strategy for agricultural production systems, ensuring greater sustainability.
