Furrows opening mechanism for nitrogen fertilizer application in common bean crop under no-tillage

摘要

Some crops have shown no adaptation to no-tillage system as a function of compaction soil superficial layer. In way, the mechanism used in seeder to open furrows for deposition of fertilizer call have great importance to facilitate the penetration of roots. This experiment was carried in Selviria (MS), with the objective to evaluate the winter common bean crop yield under no-tillage system, as function of fertilizer distribution opening mechanisms in sowing (chisel and coulter blade) and sidedressing nitrogen application (0, 25, 50, 75, 100 and 125 kg ha(-1)). The experimental design was a randomized block, arranged in a 2 x 6 factorial scheme, constituted by fertilizer distribution opening mechanisms in sowing (chisel and coulter blade) and sidedressing nitrogen doses (0, 25, 50, 75, 100 and 125 kg ha(-1)), With four replications. It is recommended the use of chisel as mechanism to open furrows for fertilizer deposition for the winter common bean crop cultivation. The sidedressing nitrogen application provides increment to the winter common bean crop yield.
