Abstract

The objective of the present work was to evaluate three different managements of the Pennisetum glaucum (L.) R. Brown crop and two-speed displacement in a no-tillage system of soybean (Glycine max L.) crop on a typical Eutrophic Red Latosol. The experiment was arranged in six treatments, in a factorial array, in a randomized complete block design, with four replications. The treatments were constituted from three combination of crop managements (straw chopper, residue coulter and herbicide) and two speed displacement of the seeding-fertilizer machine (5.2 and 7.3 km h-1). The following variables have been analyzed: emergency index of the soybean, longitudinal seeding uniformity (evaluated by the percentage of acceptable spacings), double distribution and distribution failure, and operational capacity of the seeding-fertilizer machine. There was no difference on the mass decomposition of the Pennisetum crop after management. The management of the Pennisetum crop and the displacement of the seeding-fertilizer machine did not influence the number of days for soybean crop emergency and the longitudinal distribution of the seeds. The operational capacity of the seeding-fertilizer machine was higher at the faster speed. The crop yield did not differ on the studied treatments. (AU)
