Cultivation
· Using a peg-toothed harrow, cultivate or off bar 10-15 days after emergence to control weeds.
· If needed, hill up at 25-30 days after emergence to ensure easier penetration of pegs into soil and proper formation of pods particularly in clay soil. However, hilling up may promote build up of Sclerotium roltisii which causes stem rot disease and sprouting of early developed pods.
· Avoid cultivating at the peak flowering and pegging stages to prevent abortion of first open flowers and disturbance of pod formation.
