Durante el ciclo de cultivo de 1972, se investigo el efecto de la densidad de plantas sobre el crecimiento y rendimiento de la variedad de frijol Canadian Wonder. Al aumentar la densidad de plantas, aumento la MS total del cultivo y el IAF. La produccion de grano/ha al momento de la cosecha aumento en un 27, 50 y 48 por ciento y el no. de vainas/ha. aumento en un 24, 57 y 99 por ciento cuando la poblacion de plantas aumento de 74.000 a 111.000 a 222.000 y 444.000 plantas/ha. respectivamente. La relacion peso del tallo/peso de las vainas al final de la cosecha, disminuyo al aumentar la densidad de plantas. La tasa promedio de crecimiento del cultivo aumento al incrementar la densidad de plantas, pero la tasa neta de asimilacion y la tasa relativa del crecimiento disminuyeron al aumentar la densidad de plantas. La cantidad de luz interceptada aumento, al crecer el IAF y la tasa neta de asimilacion disminuyo al aumentar la cantidad de luz interceptada por las hojas superiores. El indice de cosecha fue mayor a bajas densidades que a altas densidades. (RA-CIAT) spa
The influence of varying plant densities on growth and yield of beans var. Canadian Wonder was investigated during the 1972 growing season. Total crop DM and LAI increased with increase in plant density. Grain yield/ha at final harvest increased by about 27, 50 and 48 percent, respectively, and pod no./ha increased by about 24, 57 and 99 percent, respectively, when plant population was increased from 74,000 to 111,000; 222,000; and 444,000 plants/ha. The ratio of stem to pod wt. at final harvest decreased with increasing plant density. Mean CGR increased with increasing plant density but NAR and RGR decreased with increasing plant density. The quantity of light intercepted increased with the increase in LAI and NAR decreased with the increase in the amount of light intercepted by the upper leaves. HI was higher at low than at high plant densities. (AS) eng
