Pigeon pea, a widely spaced row crop having initial slow growth is sensitive to weed competition during early stages of its growth period. A large proportion of uncovered land during early stages is taken over by rank weed growth, which may cause drastic reduction in growth and yield of pigeon pea. Pigeon pea with additional canopy may suppress weeds, due to shade. To accomplish the same, foliar application of micro nutrient mixture and growth promoters as well as mulching with black gram crop resides were made to increase the growth and spread of pigeon pea and to find its effect on growth, yield and weed suppressing ability.
