Doses de fósforo na produção de sementes de soja e desempenho na produção de grãos

Abstract

Objective of this study was to evaluate the effect of application of different phosphorus levels in the production of soybeans and performance in grain production. The experiment was conducted on company property Costa Seeds Drink, located in the municipality of Condor / RS.As property of soil characteristics summarized in a dark red latosol, which consists layer 0-20, the following conditions, MO, ph , base saturation, aluminum, phosphorus and potassium. This area is used no-tillage and irrigation center pivot system. They were deployed in the 2013/2014 season and experiment with cultivating DM 5958 RSF IPRO. The yield components evaluated were of productivity in crops 13/14 and 14/15, height of plants, plants per meter, number of productive internodes, pods per Internode and grains per pod. Regardless of the dose used in the first season of Fosforo considering a seed enrichment, she did not show field productivity gap, also in productivity components.
