Description A study was conducted for 2 years (1995 and 1996) on productivity Qf rainfed castor (Ricinus communis L.) alleycropped with white papinac [Leucaena leucocephala (Lam.) de Wit] with conjunctive application of green leaf manuringand nitrogen. The result showed that the seed yield of castor was significantly higher in alley cropping of castor 598.9kg/ha (1995) and 474.5 kg/ha (1996) compared with the sole cropping (473.7 and 265.5 kg/ha during 1995 mid 1996respectively). Incorporation of green leaves of white popinac at 5 tonnes/ha 10 days before sowing of castor increasedthe seed yield of castor signiticantly both in alley cropping (669.4 and 512.5 kg/ha) in 1995 and 1996, respectively andin sole cropping with values of 531.2 kg/ha (1995) and 315.4 kg/ha (1996) over without green leaf manuring. Significantlylow seed yield of castor was noticed at zero and 40 kg N/ha compared with the 80 kg N/ha during 1995 (710.6kg/ha) and 1996 (384.9 kg/ha). Combined application of green leaves of white popillac with 40 kg N/ha producedsignificantly more seed yield ofcastor both in alley cropping with values 01'708.3 kg/ha (1995) and 559.3 kg/ha (1996)and sole cropping (575.7 and 318.6 kg/ha during 1995 and 1996 respectively) over separate application of 80 kg N/hawithout green leaf manuring. Similar response was observed in dry matter production, crop growth rate and nitrogenuptake of castor to all the treatments.
