Recovery of pasture with the introduction of legume

Abstract

In Brazil, and especially in the State of São Paulo the pastures are the forms more used in the animal feeding, totaling a total of 72% on average, and great part is in degradation process. The present study will have for objective to evaluate the consortium signal grass (Brachiaria decumbens) with Estilosantes Campo Grande (Stylosanthes capitata (80%) and S. macrocephala (20%)) under different systems of implantations. In the experiment, the experimental design will be used in blocks at random in outline of subdivided portions, with four repetitions and composed by five treatments (main portions) and a witness, to proceed described: T1 = direct planting with drying; T2 = direct planting without drying; T3 = direct planting with scarification of the soil, T4 = railing rome + direct planting; T5 = conventional system (breeze + railing) and T6 = witness. In the subplots they will be appraised the presence and absence of manuring phosphated. The experiment will be accomplished in the Agency From São Paulo of Technologies of Agronegócios - APTA Extreme Oeste, in the municipal district of Andradina/SP of December of 2010 to November of 2011 in soil classified like Latossol Red. The evaluations to be accomplished will be the production of dry matter, sheet percentage to foliate, stem percentage + it hems, percentage of dead material, legume percentage, percentage of plants forayer and composition botanical bromatology of the plants of signal grass and estilosantes Campo Grande, evaluation of the system roots and of the characteristics chemical of the soil and economical analysis of the techniques of renewal of the pasture. As expected benefits intend to determine more efficient practices of recovery of pastures degraded associated or fertilized with match, and the most appropriate forms of maintainable production.
