Adubação verde com crotalária consorciada ao minimilho antecedendo a couve-folha sob manejo orgânico1/Green manure by intercropping crotalaria with baby corn before kale under organic management

The experiment was conducted in Seropedica, State of Rio de Janeiro, with three treatments for green manure, composed of corn, corn intercropped with crotalaria, and crotalaria, in randomized blocks. Baby corn was harvested during growth. After cutting the plants, the treatments were combined with two ways of soil preparation: no-tillage and conventional preparation, in a subplot design, with subsequent planting of kale. The evaluations were the production of fresh and dry matter and accumulation of nutrients in the aerial part of green manures; yield, straw weight and number of ears; nutrient accumulation in the ears; length, diameter, and weight of the baby corn ears and number of ears per plant; yields, number of leaves, leaf area, dry matter, yield per harvest, specific area per harvest and accumulation of N in the kale; and balance of N in the system. The accumulation of nitrogen provided by the intercropping was greater than the corn monoculture, but equivalent to the crotalaria monoculture.
