Abstract
A study was conducted for 2 years (I 995 and 1996) on productivity of rainfed castor (Ricinus communis L.) alley cropped with white popinac (Leucaena leucocephala (Lam.) de Wit) with conjunctive application of green leaf manuring and nitrogen. The result showed that the seed yield of castor was significantly higher in alley cropping of castor 598.9 kg/ha (1995) and 474.5 kg/ha (1996) compared with the sole cropping (473.7 and 265.5 kg/ha during 1995 and 1996 respectively). Incorporation of green leaves of white popinac at 5 tonnes/ha 10 days before sowing of castor increased the seed yield of castor significantly both in alley cropping (669.4 and 512.5 kg/ha) in 1995 and 1996, respectively and in sole cropping with values of 531.2 kg/ha (1995) and 315.4 kg/ha (1996) over without green leaf manuring. Significantly low seed yield of castor was noticed at zero and 40 kg N/ha compared with the 80 kg N/ha during 1995 (710.6 kg/ha) and 1996 (384.9 kg/ha). Combined application of green leaves of white popinac with 40 kg N/ha produced significantly more seed yield of castor both in alley cropping with values of 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/ha without green leaf manuring. Similar response was observed in dry matter production, crop growth rate and nitrogen uptake of castor to all the treatments.
