PRODUÇÃO E QUALIDADE DE SILAGEM DE MILHO COM CULTIVARES DE Panicum maximum E FEIJÃO GUANDU EM SISTEMA INTEGRADO

Abstract

One of the most expensive components in formulating and composing a diet for ruminants is protein. Corn silage has crude protein values ​​between 6 and 9%, which is often not enough to maintain high production. In this context, integrated annual cropping systems with tropical forages for silage production can increase the nutritional value of silage and reduce costs with protein foods. Therefore, the objective was to evaluate the production and quality of corn silage intercropped with cultivars of Panicum maximum and pigeon pea. The experimental design used was completely randomized, with four replications. The experiment was conducted in randomized blocks, with three replications. The treatments consisted of silage: corn (Zea mays L.) in monoculture; tamani grass (Panicum maximum cv BRS Tamani) in monoculture; Kenya grass (Panicum maximum. cv BRS Kenya) in monoculture; zuri grass (Panicum maximum cv. BRS zuri) in monoculture; pigeon pea (Cajanus cajan cv. BRS Mandarim) in monoculture; corn intercropped with tamani grass + pigeon peas; corn intercropped with kenya grass + pigeon peas; corn intercropped with zuri grass + pigeon peas. The results demonstrated that corn silage intercropped with Panicum maximum and pigeonpea cultivars increases the production of ensiled mass by 37.86% compared to corn silage in monoculture and improves the nutritional value of monoculture crops. Thus, the silage produced by the triple consortium proved to be an efficient technique for producing food in a sustainable way, allowing greater intensification of the production system.
