Abstract

The objective of this work was to evaluate the effect of different forms of reimplantation of pasture with and without phosphatation aiming to contribute to the increase of soybean yield. The experiment was conducted at the Experimental Farm of Universidade do Oeste Paulista (Unoeste), located in the municipality of Presidente Bernardes - SP. The design was done with split plot scheme, containing four replicates. The plots were constituted with 4 kg ha^-1 of Urochloa brizantha (Marandu grass), BNS + Seeding in haul, BNS + Seeding in line consortium with soybean as subplots (with and without phosphatation). The following were analyzed: number of tillers and dry mass yield (PMS); analysis of plant tissue from pasture; foliar diagnosis analysis; and components of production and production of soy. Analyzed variables were submitted to analysis of variance (p <0.05) and means were compared by the Tukey test (p <0.05). In this context, it can be concluded that a higher quality production with a reimplantation of pasture intercropped with a soybean crop yielding an increase of 276 kg ha^-1 compared to the treatment that did not have pasture reimplantation (BNS). Phosphate increased soil phosphorus content in the production of soybean dry matter and no leaf phosphorus content and higher soybean yield.

Key words: Natural seed bank, no-tillage, Urochloa brizantha.
