Estudo de rendimentos de 16 variedades de feijão vulgar - phaseolus vulgaris l. nas estações agrárias do Chókwe e Umbeluzi

Abstract

This work has as general objective to evaluate the behavior of 16 varieties in terms of yield, in different environments. And its specific objectives are: 1. Evaluate the response of the 16 varieties regarding the production of the grain and its agronomic adaptability in different environments. 2. Identify the growth habits that show the best performance. The material used consisted of data obtained from the trials carried out, agricultural stations in Chókwe and Umbeluzi in the 95/96 campaign of the 16 varieties. The data collected refer to the grain yield. The results showed that in Umbeluzi there were no significant differences and the results were low, ranging from 161.7 to 413, 2 kg per hactare. While in Chókwe there were significant differences, and yields relatively high; from 833.3 to 1883.3 kilograms per hactare. The varieties that showed the best grain yield in this agrarian season were: S-TMR-18 P, Smo1, S-TMR-31P, Encarnado and ENS2. The water deficit caused a decrease in yields in all varieties, there was an influence of the environment on the genetic expression of the varieties and the interaction verified was of the cross-type. Varieties whose growth habit allows for greater development and have a greater number of nodes, showed better yields in the most favorable environment.
