Ajuste do rendimento para a variação do estande em experimentos de melhoramento genético do feijão

Abstract: O objetivo deste trabalho foi avaliar o ajuste do rendimento pela variação do estande em experimentos de feijão e propor procedimento para ajustamento por análise de co-variação. Utilizaram-se dados de 33 ambientes do Ensaio Estadual de Feijão do Rio Grande do Sul. Realizaram-se as análises de variação e de co-variação de rendimento e de estande em cada ambiente. Foram considerados quatro modelos de ajustamento alternativos: sem ajuste para a variação do estande; com ajuste para o estande médio geral; com ajus… Show more

“…This relation of FS to grain yield differs in the literature, being dependent on the size of the reduction in the stand. Authors such as Ribeiro et al (2004) state that the FS does not affect yield in the bean crop, while Piana, Silva and Antunes (2007) remark that the yield can be affected by variations in the final plant population. Another explanation was the Application of molybdenum and a desiccant herbicide to the common bean under direct seeding Table 3 shading caused by the presence of standing brachiaria straw, which had not been mown in 2010, promoting etiolation in the bean plants and a consequent reduction in the initial development of the crop that year.…”

“…For the year effect, the average PNP was higher in 2010 (Table 3). The probable reason for this fact is the plasticity of bean plants, which are able to compensate the primary yield components in different environmental conditions, including the plant population (Piana et al, 2007), which in 2010 was lower than in 2009 (Table 2).…”
