Summary

Studies on productivity of pigeonpea-wheat cropping systems at the Indian Agricultural Research Institute, New Delhi during 1984–6 revealed that wheat following summer pigeonpea and given 120 kg N/ha produced 4–93, as compared with 451 t grain/ha when it succeeded kharif pigeonpea. Intercropping of preceding pigeonpea with dhaincha for green manure, fodder cowpea and greengram (grain) gave higher yields of 4·35, 397 and 3·68 t/ha respectively than the wheat following pigeonpea alone (3·20 t/ha). Similar effects on wheat straw were also recorded. Summer-sown pigeonpea produced 2·38 t grain/ha without any adverse effect of intercrops. However, kharif pigeonpea produced grain yield half of that obtained in the summer-sown crop. Further, the reductions in grain yield of kharif pigeonpea due to dhaincha, cowpea and greengram were 0·60, 0·52 and 030 t/ha, respectively. Summer pigeonpea + dhaincha-wheat and summer pigeonpea+greengram-wheat proved their superiority over other cropping systems.
