Abstract

A two year field study (1993 and 1994) revealed that intercropping of sunflower (Helianthus annuus L.) with black gram (phaseolus mungo L) was most productive interms of sunflower equivalent yield. Sunflower + black gram recorded the highest sunflower equivalent yield (1377 kg/ha) land equivalent ratio (1.19), highest net return (Rs.10088/ha) and benefit cost ratio (3.74). Among the sole cropping. pigeon pea recorded more sunflower equivalent yield, (1559 kg/ha) the highest net return, (Rs. 11588/ha) and benefit cost ratio (3.90). Intercropping of pigeonpea (Cajanus cajan) with sunflower was least productive combination among the intercropping combinations.
