Abstract: Field experiments were conducted in summer 2003 and winter 2003-04 to find out the effect of unconventional green manure incorporation on growth and yield of cotton. Three green manures viz., marigold and sesamum and sunnhemp as intercrops were raised in single and double row incorporating them in the interspace of hybrid cotton TCHB 213 on 30 and 40 DAS with the objective to find out diverse use of green manures as a source of nutrients and as a way of weed and pest control in cotton with an aim of improved growth and yield. The results revealed that intercropping with marigold in two rows in between cotton rows and incorporating it in situ on 30 DAS had contributed ultimately more kapas and lint yield securing higher yield advantage in both summer and winter crops.
