Abstract

This research aimed to study a possible synergistic effect with inoculation with A. brasilense and N doses, associated with the application of silicon in acidity corrective form, evaluating the grain yield of irrigated wheat in Cerrado region. The experiment was conducted in Selviria. MS. Brazil, under a no-till system, on a Latossolo Vermelho distrofico (Oxisol). The experiment was set up as a randomized block design with four replications, in a 2 x 5 x 2 factorial arrangement consisting of two soil corrective sources (dolomitic limestone and Ca and Mg silicate as source of Si); five N doses (0, 50, 100, 150, and 200 kg ha(-1)) applied in topdressing; and with and without inoculation with A. brasilense. Inoculation makes wheat production more profitable, irrespective of N doses and corrective sources. The N dose of 139 kg ha(-1) with dolomitic limestone associated with inoculation of A. brasilense provided the greatest grain yield. However, the highest economic return was obtained at the N dose of 100 kg ha(-1), with dolomitic limestone application and inoculation. (AU)
