Plantas de cobertura de solo em pomar de pessegueiro (Prunus persica L. Batsch) conduzido no sistema de produção integrada

Abstract

This research was carried out in the South of Brazil with the objective to examine the effects of five cover crops and their combinations on peach orchard leaded in Integrated Crop Management. The experimental orchard was installed in 1999 at 1.5 x 5.0m planting density, with two training systems: Central Leader (CL) and Ypsilon Shape (Y). The increment on trunk diameter, the increment on foliage size, the frequency productive buds, fruit yield, fresh and dry matter were evaluated. The combination of different cover crops was beneficial considering the productivity with distinction to the Avena strigosa+Pisum sativum combination. The trunk diameter of peach tree was not influenced by cover crops. Nevertheless, the foliage size, frequency productive of buds, and productivity were significantly affected by the cover crops.
