FOOD FODDER INTERCROPPING AND PHOSPHORUS MANAGEMENT IN OAT (AVENA SATIVA L.), CHICK PEA (CICER ARIETINUM L.), LENTIL (LENS CULINARIS MEDIKUS.), GREEN GRAM (VIGNA RADIATA L. WILCZEK), RICE (ORYZA SATIVA L) CROPPING SEQUENCE UNDER LATERITIC SOIL

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.
