Abstract

A field experiment was conducted during kharif season of 2004 at Main Agricultural Research Station, Dharwad (Karnataka) to study the feasibility and adaptability of intercropping of maize and pigeonpea in 1:1,2:1,2:2,3 :1 and 4:2 row proportions with 50 and 100% pigeonpea population levels. Sole crop of maize and pigeonpea recorded significantly higher grain yield (6337 and 1090 kg ha-1 respectively) over intercropping systems. Among intercropping systems, intercropping of maize and pigeonpea at 4:2 row ratio with 50 per cent pigeonpea population resulted in maximum maize equivalent yield (8076 kgha-1), net returns (Rs. 30492 ha-1) and B:C ratio (2.75) over other intercropping systems and sole crops.
