Seed yield and seed quality of bush bean (Vigna sesquipedalis Fruw) as affected by seed size and plant population density
1987
Yuvavan, S.
Field and laboratory experiments were conducted from November 1986 to February 1987 to determine the effects of plant population density and seed size on yield and seed quality of bush bean. The population densities were 88,888, 133,333 and 266,666 plants per hectare, and the four seed sizes were large, medium, small and bulk seeds. Split-plot in Randomized Complete Block Design (RCBD) with three replications was used. Plants derived from large seeds flowered earlier, produced greater number of branches, grew taller, had higher leaf area index, higher dry matter yield, greater number of pods, larger pods, more seeds per pod, heavier seed weight and higher seed yield. Large seeds produced plants with better seed quality than the other seed sizes as reflected in the higher germination coefficient and the vigor test. Plant population did not influence the quality of seeds. Plant population density likewise influenced the growth, yield and yield components of bush bean. Higher seed yield was produced in higher plant population, however, the weight of seeds was higher and other yield parameters were comparatively better at lower plant population densities. The quality of seeds in terms of germination and vigor was not influenced by plant population.
