BEAN CULTIVATION UNDER DIFFERENT PRODUCTION SYSTEMS IN THE NORTHEASTERN OF SÃO PAULO STATE

Abstract

The experiment was carried out at the Research Farm, Camilo Castelo Branco University, UNICASTELO, Fernandópolis (SP). It aimed at studying the effects of different soil preparation systems about the behaviour of bean culture in winter. The experimental area was carried out in randomized blocks with three treatments and four replications with plot dimension of 1.0 x 1.5m (1.5m2). The treatments used were PC: bean yields under conventional tillage in winter and mechanic control of weeds; CM: bean yields under minimum tillage in winter and chemical control of weeds; PD: bean yields under direct tillage in winter and chemical control of weeds. This study evaluated the dry matter production, the plant development and the bean production. The data showed that the average bean development was higher under the direct tillage system. All the production systems studied showed both dry matter and grain productions are similar, demonstrating that the highest development couldn’t be observed under these conditions. It is necessary to keep on studying these kinds of conditions in order to obtain more consistent results.
