Effect of planting time and spacing on the yield performance of bushbean (Phaseolus vulgaris L.) in the eastern hilly area of Bangladesh

An experiment was conducted in split plot design with six spacing and three planting time of dwarf French bean (Phaseolus vulgaris L.) during the period from October, 1998 to March, 2000. Earlier (October, 15) planting took longer time for flowering and fruiting while late planting (December, 15) gave early flowering but number of pod and pod yield decreased. Wider spacing gave higher number of pod and pod yield per plant but closer spacing gave higher number of pod and pod yield per unit area. The highest yield (24.16 t/ha) was obtained from 25 x 10 cm spacing of mid-November planting. Plant height, number of branches, foot and root rot disease infestation was higher in earlier planting and was minimum in late planting.
