Systems of soil management practices and ways of inoculation with Azospirillum brasilense in the second crop of corn under Cerrado

Abstract

The project will be developed during the agricultural year 2013/14 at the experimental farm of Teaching and Research of the Universidade Estadual Paulista, located in Selvíria (MS). The local soil type is Typic Dark dystrophic 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 randomized block with four replication. Each block will consist of eight treatments, consisting of two systems of soil management practices (heavy + harrowing and no-tillage), four ways of inoculation with Azospirillum brasilense (by seed, by leaf spray, by seed + by leaf spray and absence of inoculation. The inoculation by leaf spray will be at the stage of plant V4 in the second crop of corn. The objective is to evaluate the effect of ways of inoculation with Azospirillum brasilense in two systems of soil management practices, the possibility of interaction between the ways of inoculation and the systems of soil management practices, as well as, increase the productivity the second crop of corn under cerrado vegetation in no-tillage.
