Integrated nutrient management in clusterbean (Cyamopsis tetragonoloba) under irrigated conditions

The experiment was conducted at Research Farm of Punjab Agricultural University Regional Station, Bathinda during kharif seasons of 2008–09 and 2009–10. The results showed that application of fertilizer at the rate of 10 kg N+20 kg P₂O₅/ha and 20 kg N+40 kg P₂O₅/ha increased the mean seed yield to the tune of 10.7 and 19.6% over the control, respectively. The application of Rhizobium and PSB increased mean seed yield by 9.2 i nd 19.1% over control, respectively. However, the combination of both inoculants further failed to significantly increase the seed and straw yield of clusterbean further.
