Abstract

The project will be developed during the agricultural year 2012/13 at the experimental farm of Teaching and Research of the Universidade Estadual Paulista, located in Selvíria (MS). The local soil type is Typic Dark-epi-eutrophic Alic and clayey, originally under cerrado vegetation. The average annual rainfall is 1330 mm, the mean annual temperature is 25 º C and relative humidity of 66% annual average. The experiment will be subsubdivided plots with four replications. Each block will consist of sixteen treatments, consisting of two systems of soil management practices (heavy + harrowing and tillage), four nitrogen rates (zero, 40, 80 and 120 kg ha-1) in the presence and absence of seed inoculation with Azospirillum brasilense. The objective is to evaluate the effect of seed inoculation with Azospirillum brasilense in two soil management systems, the possibility of reduction in nitrogen application by seed inoculation with Azospirillum brasilense, but also increase the productive efficiency of upland rice no-tillage systems.
