Consorciação de forragens em um latossolo sob plantio direto em mato grosso do sul

Abstract

Green manure, used both in succession as in crop rotation is an excellent practice vegetative soil conservation, since savings in fertilizers, is descompactante, restores good chemical, physical and biological and, especially, increases plant productivity. In the 2006/2007 crop year, the Teaching and Research Farm of the Faculty of Engineering of Single Island - FEIS / UNESP, located under the conditions of the Brazilian Cerrado (22° 23'S and 51? 27' W), we analyzed the productivity of the mass dry forage intercropping millet + pigeonpea (MSF) in terms of physical attributes of soil penetration resistance (PR), gravimetric moisture (UG), volumetric water content (UV) and bulk density (DS) in depths of 0.00-0.10m, 0.10-0.20m and 0.20 to 0.30 m. To that end, we installed a mesh data containing 117 sampling points in a Hapludox under center pivot under no-tillage in an experimental area of 1600m 2. Statistical analysis was comprised of descriptive analysis attributes of the original, simple linear correlation analysis and space between them, and finally, geostatistical analysis, aiming, above all, provide evidence of conditions that increase agricultural productivity. The productivity of forage dry matter was high, but not spatially correlated with the attributes of the soil studied. The water content and bulk density were the soil attributes that most closely related to estimate soil physical quality.
