Desempenho agronômico de genótipos de feijoeiro comum, do grupo carioca, no período das águas, em Uberlândia-MG.

Abstract

Common bean (Phaseolus vulgaris) is an annual plant that has the characteristic of being a plant herbaceous, climbing or creeping type, with indeterminate growth and pods of 9 to 12 cm that can contain 3 to 7 seeds. The cultivation of this plant has been stooded out by the great demand in the world for this food and, mainly, for being a plant with differents edaphoclimatic adaptations, which allows its cultivation throughout the year. In this sense, the presente study aimed to evaluate the agronomic characteristics of common bean genotypes, of the Carioca group, in the water season in Uberlândia-MG. The experiment was accomplished at the Água Limpa Experimental Farm, owned by the Federal University of Uberlândia, located at the geographic coordinates 48º 21’ 04’’ of longitude W and 19º 06’ 09’’ of latitude S, with an average altitude of 800 meters. The experimental design used was randomized blocks (DBC), being constituted of 21 treatments, with 3 replications, totaling 63 plots. Each plot consists of 4 lines spaced 0.5m apart and 4 meters long, totaling a total area of 8 m2. The seeds of the genotypes (treatments) were sown in a zigzag system with 60 seeds per row, that is, 15 seeds per linear meter, totaling 180 seeds per plot. The harvest was done only in the two central lines, the other two were considered borders. In addition, the present work is part of the Cultivation and Use Value (VCU) developed by Embrapa Arroz e Feijão in different regions of Brazil. The data obtained were submitted to analysis of variance, using the F test, and the Scott-Knott test at 5% probability was used to compare the means. The treatments did not show significant differences for the characteristics: pods per plant, yield and grains per pod. In relation to the characteristic mass of 100 grains, there was a significant difference, with emphasis on the genotypes VC41, Pérola and BRS FC406, which presented the highest averages compared to the other genotypes.
