Desenvolvimento, produtividade e resistência do solo à penetração nas culturas de aveia preta e nabo forrageiro em dois tipos de manejo do solo no ano de 2005.

Abstract

The present work had for objective to evaluate the development, productivity and resistance of the soil to the penetration in the cultures of black oat and fodder radish, in two types of soil handling in the region of Lages, SC, observing the best covering of soil in a quantitative and qualitative way. In this work the experimental design was used in blocks, tends in the portions the preparation (with chiselling and without chiselling) and in the split plot the winter cultures (black oat and fodder radish) and in the split split plot the depths in the soil (0-10, 10-20, 20-30, 30-40, 40- 50cm), with five repetitions. The productivity of the black oat was 46% larger than of the fodder radish, being influenced by the handling with chiseling. The fodder radish under no tillage contributes in the reduction of the resistance the penetration in 13%. The layer explored by the chiseling provided smaller values of resistance of the soil to the penetration.
