Sucessão entre cultivos orgânicos de milho e couve consorciados com leguminosas em plantio direto

Organic crop succession of maize and collard greens intercropped with legumes in no-tillage system New farming practices have been developed to reduce the application of fertilizer and pesticides and minimize the aggression to the environment, producing healthy foods and environmentally correct. We evaluated the performance of the succession of collard greens (Brassica oleracea L. var. acephala) and corn (Zea mays L.) intercropped with green manure legumes under no-tillage organic system. The study was conducted in Seropedica, Rio de Janeiro State, during two years. We utilized dwarf velvet bean (Mucuna deeringiana) and showy crotalaria (Crotalaria spectabilis) as green manure intercropped with collard greens and in succession sunn hemp (Crotalaria juncea) and velvet bean (Mucuna pruriens) intercropped with corn. As a control, there was a single crop system of corn and collard greens. The experimental design was of randomized complete blocks, a factorial 3 (crop system) x 2 (doses of poultry bed manure), with four replications, in plots of 20 m 2 . For the collard greens we applied 0 and 5.4 t ha -1 of poultry bed manure (2.7 t ha -1
