Abstract: A two-year field study was conducted during kharif, 2003 and 2004 at the Pulses and Oilseeds Research Sub-station, Beldanga, Murshidabad, West Bengal to evaluate the performance of liquid and carrier based Rhizobium inoculants in urdbean.The results revealed that though the basal application of inorganic N either at 20 or 40 kg ha-1 gave the highest seed yield, it was closely followed by the seed inoculation treatment with liquid Rhizobium inoculant (LRI) prepared at the Pulses and Oilseeds Research Station (PORS), West Bengal and carrier based Rhizobium inoculant (CRI) prepared at the PORS, W.B. Yield advantages due to inoculation with LRI (PORS) and CRI ((PORS) were 13.06 and 9.61%, respectively, over the uninoculated control. There was positive correlation between symbiotic traits (nodule number, nodule dry weight and total dry matter per plant) with seed yield of urdbean.
