Response of Pole Beans (Phaseolus vulgaris L.) to Various Plant Densities

Abstract

The effect of four spacings within the row (8, 15, 23 and 30 cm) on the marketable yield of four commercial pole bean varieties, (McCaslan 42, Romano, Kentucky 191 and Blue Lake S-7 Stringless), was evaluated on a winter planting at the Adjuntas Experiment Substation. At the 8 cm spacing, variety Romano was the highest yielder (12,523 kg/ha) while Kentucky 191 had the lowest (9,542 kg/ha). At 15 cm, Kentucky 191 yielded 10,004 kg/ha; and McCaslan 42 only 8,297 kg/ha. At 23 cm, Blue Lake S-7 was highest in yield (11,587 kg/ha) while Romano had the lowest (5,928 kg/ha). At 30 cm, Kentucky 191 was the highest yielder (9,442 kg/ha) while McCaslan 42 was the lowest (4,659 kg/ha).
