Intercropping studies with arhar (Cajanus cajan) var. T21 were conducted under irrigated conditions during 1972 and 1973 at the Punjab Agricultural University, Ludhiana. The planting of one row of either mash (Phaseolus mungo) or mutig (Phaseolus sureus) in between two rows of arharh spaced 75 cm. apart, increased the yield of arhar, whereas a sllght reduction in its yield was recorded with groundnut and soybean. Intercropping with maize reduced the arhar yield by 101 per cent. The maximum cash returns (%) over arhar grown alone was recorded from intercropping with a short-duration variety T9 of mash, followed by groundnut and mung. The intercropping of maize and soybean proved to be a losing proposition.
