Efecto de la densidad de siembra en la distribución de materia seca en la planta de frijol (Phaseolus vulgaris L.)
The purpose of this study was to evaluate the effect of sowing at four different densities on the production of dry weight per square meter, dry weight per plant, and relative distribution of dry weight among different parts of the plant in four varieties of bean (Phaseolus vulgaris L.) The four varieties were sown at 6, 12, 24 and 48 plants per square meter: plants were selectively removed 15 days after emergence to achieve these densities. The plot dimension was 24 m2; the statistical design used was a split plot with four replications per variety, where the major effect was the variety and the minor effect was the density in the lanvest period, 10 m2 per variety were sampled and one additional sample of 1 m2 was taken for studying only. yield components. This material was dried and the following were recorded a) Dry weight of vegetative aerial structures, b) Dry weighıt of reproductive structures (pods and seeds), c) LDry weight of roots As sowing density increased, total dry weight per area increased, but dry weight per plant decreased, weiglıt reduction was greatest in the reproductive structures pods and seeds) . Relative weight of branches increased at higher densities, but relative weight of the main stem remained constant. As sowing density increased, relative weight of green leaves, pods and seeds produced on branches decreased, but the relative weight of the same structures produced on the main stenn increased.
