Abstract
A field experiment was conducted during the rainy season of 1999 and 2000 at Baruipur, to evaluate different planting patterns of sunflower (Helianthus annuus L.) and pigeonpea [Cajanus cajan (L.) Millsp.] intercropping. Various growth and yield attributes and yield of sunflower and pigeonpea were superior under sole cropping. Inter cropping of sunflower and pigeonpea in 3:l row proportion and in 2:2 row proportion showed better manifestation of growth and yield attributes in sunflower and pigeonpea respectively. All the intercropping patterns were superior in terms of sunflower equivalent yield and income equivalent ratio (IER) values to sole crops. Intercropping of sun flower,and pigeonpea in 3:l row proportion was the best system, recording the highest sunflower equivalent yield (2,480 kglha), land equivalent ratio (1.38), product of crowding coefficient (k 5.94), income equivalent ratio (1.73), benefit : cost ratio (2.06), gross (Rs 19.840lha) and net returns (Rs 10,212lha) and monetary advantage (Rs 5,463/ha).
