Abstract

A field experiment was conducted to study the effect of sunflower on the performance of intercrops. Smothering effect of sunflower on the associated inter- crops was minimised when the intercrops were sown in advance. Advancing the sowing of intercrops viz. cowpea and groundnut by 7 to 14 days prior to sowing of sunflower increased the yield of both the intercrops, Nitrogen applied to sun- flower had no effect on the yield and yield attributes of intercrops.
