Abstract: Two sets of experiments were conducted, one at lateritic soil zone and another one at the alluvial soil zone of West Bengal, India during 1998-2000. The result of experiment at the lateritic zone revealed that maximum (1.47 t/ha) seed yield of rice bean was recorded when crop received 20 kg nitrogen, 80 kg P2O5 and 40 kg K2O/ha. From the experiment conducted at the alluvial zone it revealed that rice bean yielded more (1.26 t/ha) than that of blackgram (1.02 t/ha). At the same time maximum seed yield of both ricebean (1.51 t/ha) and blackgram (1.14 t/ha) was recorded when the crop received 50% recommended doses of nutrient applied through chemical fertilizer along with another 50% recommended doses throiugh poultry manure. This was closely followed by that of 100% recommended doses of nutrient through chemical fertilizer (1.15 and 1.39 t/ha in blackgram and ricebean, respectively).
