ADAPTABILIDADE DE VARIEDADES DE SOJA PARA REGIÃO EDAFOCLIMÁTICA DE MORRINHOS - GOIÁS

Abstract

The aim of this study was to evaluate and identify the adaptability of different soybean varieties (Glycine max). For edaphoclimatic Region Morrinhos – GO. The experiment was conducted in the 2015/16 season , where the climate is classified as Koppen , as aw , the soil of the area and classified as Oxisol. Using the design of randomized blocks with four replications , 18 treatments , of which eleven are lines and seven witnesses and commercial varieties . The plots consisted of four rows of 5.0 m long, spaced 0.45 m, using as floor area 4 m of the two central lines , despising 0.5 m on each side , as a border . The agronomic characteristics of soybean were evaluated and all following standards commonly used field average degree of bedding plant, number of branches per plant, number of pods per plant per pod grain number, plant height, and insertion height of the first pod, stem diameter, productivity performance evaluation and thousand seed weight. Harvesting was performed separately for each treatment Manual when these 95% of the pods at maturity, or R8 stage. The treatments showed significant using the Tukey's test at p <0.05 probability. The T18 range with higher productivity the average of the best witnesses adapted.
