Effect of clump planting of maize and time of planting of beans on growth and yield of intercropped maize and beans

Two field experiments were conducted at the University of Nairobi's Faculty of Agriculture Kabete, to investigate the merits of clump planting of maize and time of planting of intercropped beans on growth and yield of the maize and beans. Effect of the treatments on field weed load was also examined. Three clumping patterns of maize and three planting times of beans were tested in a factorial experiment laid out in a completely randomised block design with three replications. The clumping patterns of maize consisted of one maize plant per hill spaced at 75 and 25 cm, two maize plants per hill spaced at 75 and 50 cm, and three maize plants per hill spaced at 75 and 75 cm. The three planting times of beans were beans planted with maize at the same time, planting beans two weeks after maize was planted, and planting beans four weeks after planting of maize. The two crops were intercropped in the same row.
