DESEMPENHO AGRONÔMICO DE VARIEDADES DE FEIJOEIRO NO SISTEMA PLANTIO DIRETO

Abstract

The aim of this study was to evaluate the performance of varieties of common bean in notillage on biomass of fallow vegetation as a function of crop fertilization. The study was conducted at Bujari, AC. The experimental design was a randomized complete block split plot with four replications. The experiment consisted in the cultivation of three varieties of common bean in no-tillage on weed straw, with and without fertilization at planting subplot. The variables analyzed were grain yield, final stand, number of pods per plant, number of grains per pod and weight of hundred grains. The data were submitted to the F test and means were compared by Tukey test (p<0,05). The bean variety Carioca Pitoco has better grain yield than the Carioca and Rosinha varieties on the first year of no-tillage system. The crop fertilization increases the yield of varieties of beans grown on straw till the fallow vegetation.
