Abstract
A field experiments was cond ucted under lateritic soil, at Kankutia, dist. - Birbhum, W.B., India during 2006 – 2008 in farmers field to study the effect of food fodder intercropping and phosphorus management in oat + chick pea / lentil - green gram - rice cropping sequence under late ritic soil. Sole cropping of oat recorded highest green forage yield (32.1 t/ha). The row ratio, 2:1 of oat + pulses (chick pea / lentil) gave significantly higher fodder than their 1:1 series and SSP showed better effect (28.86 t/ha) than PRP (26.14 t/ha) . Chickpea as sole gave the highest grain yield (13.8 q/ha). But the row ratio 1:1 showed better effect on grain yield of pulses than 2:1 series. The water - soluble SSP produced significantly higher grain yield of pulses than Purulia rock phosphate. Purulia rock phosphate resulted in significantly higher yield of green gram (667 kg/ha) than SSP (555 Kg/ha). Intercropping of oat + lentil (1:1) gave significantly highest grain yield of rice. Oat + lentil (1:1) – green gram – rice gave maximum net return and ben efit - cost ratio (1.36). Use of PRP gave higher net return and B/C ratio (1.21). Oat + lentil (1:1) with PRP were found the best treatment.
