Produtividade do milho (Zea mays L.) em cultivo solteiro e consorciado com adubos verdes no cariri paraibano.

Abstract

The practice of culture consortium and green manure is often used by farmers as a way to increase agricultural production. Such activities promote improvement of the physical, chemical and biological soil and should be encouraged to minimize tillage damage in the conventional system, the time that contribute to add value to agricultural production, diversity of potential species used. The objective of this study was to evaluate agronomic characteristics and biomass production in maize is grown in monocrop and intercropped with legumes, as well as verify the perceptions of farmers on these practices. In field research conducted in the Experimental Area of the CDSA. It used design randomized with four replications. The treatments were the sole crop of maize (Zea mays L.) and corn consortia with pigeon pea (Cajanus cajan (L.) Millspaugh) and beans pig (Canavalia ensiformes (L.) DC.). The consortium between corn and green manure had satisfactory performance and yields of maize intercropped with pigeon pea and pork beans, proved superior to corn monoculture for the variables: height, stem diameter and weight of ears. Variables production number of spikes and dry weight of corn were not affected by the use of different spacing and green manures. As the production of green and dry biomass were higher in the treatment consortium corn x jack bean, regardless of spacing. The perception survey revealed that planting system in the consortium and the use of green manure is common among farmers interviewed, and the cowpea and pigeon pea beans the best known and used.
