Intercropping of pigeon pea (Cajanus cajan (L.) Millsp.) with corn (Zea mays L.) agroecologically cultivated

Abstract

Agroecology consists in not using chemicals in agricultural production. In an intercropping
planting of grasses with leguminous, the soluble nitrogen will be absorbed by the soil, increasing
their fertility, dispensing the chemicals. The objective of this work was to evaluate the cultivation
of pigeon pea (Cajanus cajan (L.) Millsp.) intercropped with maize (Zea mays L.) by the
application of organic bovine fertilizer in an agroecological system. Four levels of foundation
fertilization with bovine dung (0, 100, 150 e 200 g/pit) were made in a simple and intercropping
planting system, corn versus pigeon pea. There was no difference of pigeon pea production
in regard to the increasing applying of bovine dung. Corn obtained better length for the intercropping
planting at the dosage of 200g/pit. And the largest diameter of the corn cob in the
intercropping system with pigeon pea resulted from a better concentration of organic fertilizer
at the level of 100g/pit.
