Soil management tillage and crop on west São Paulo State

Abstract

For reform to sugarcane crops should be proposed production systems that combine environmental conservation with food production. This work will be developed in the Pólo Regional do Extremo Oeste, em Andradina-SP, The objective of this study to evaluate the effects of the succession of crops combined with different soil management systems on the productivity of sugarcane and changes in chemical and physical soil in sugarcane field reform. The experimental design is a randomized blocks in split plots with four replications. The plots treatments will consist of three soil management systems, (conventional tillage, minimum tillage and no-tillage). The split plot will be consist of two comercial crops, soybeans and corn, a choice of green manure (Crotalaria juncea + jack beans), and fallow system. The subplots will be evaluated: leaf rate and production of dry matter of shoot and root, and the grain yields. After harvesting of the crops will be planted the culture of sugar cane in the different treatments, which will be evaluated: will be tillering, leaf rate, dry matter of both and root yield, and culms yield and technology quality. In soil will be nitrogen content, and chemical and physical properties resistance to the penetration. The values obtained will be submitted to analysis of variance and means compared by Tukey test.
