Desempenho agronômico da soja em sucessão de culturas com espécies oleaginosas

Abstract

The system no tillage is leveraging the soybean productivity. In this context, crop rotation become very important issue in agriculture, and the use of some oleaginous crop species as canola (Brassica napus L. var oleífera), crambe (Crambe abyssinica Hoechst), safflower (Carthamus tinctorius L.) and radish (Raphanus sativus L. var. oleiferus), can be a positive potential to set up a rotational system or crop succession with soybean, which at the same time, be profitable and sustainable. Thus, this study aimed to evaluate the agronomic performance of soybean in crop succession with oleaginous crop species for production of biodiesel and grains. The trial was developed in the crop season 2009/2010, on the experimental farm from Universidade Federal da Grande Dourados, Department of Agronomic Science. The soil classification is Red Distroferric latosol. We used the casual blocks design, with four replications, involving four species of oleaginous crop species: crambe FMS Brilhante, radish IAC 1000 e IPR, canola Hyola 61 e safflower genetic material paraguayan and cuiabano, totalizing 6 genetic materials used as preceding crop to soybean. We conclude; the productivity of soybean was not influenced by the previous crop; the oleaginous crop species evaluated can be part of a rotational crop system with soybean.
