Abstract

The effects of over sowing methods of Desmodium ovalifolium CIAT-350 (mowing, plowing, harrowing, plowing + harrowing and manual seeding) and phosphate (P) fertilization (0 and 50 kg of P2O5/ha), on reclamation of Brachiaria brizantha cv. Marandu degraded pastures were evaluated. Legume introduction, irrespective of P fertilization, showed an effective agronomic technique for pasture reclamation. Grass and legume dry matter (DM) yields were improved by P application, while DM of weeds were depressed. In order to obtain greater forage yields and better ratio grass:legumes that ensure the productive stability of the mixture, the manual seeding and mowing plus P application were the most effective methods for oversowing the legume on grass degraded pastures.
