Studies on the effect of biofertilizer and phosphorus levels on yield and economics of urdbean (Vigna mungo L. Hepper)

A field experiment was conducted during the rainy seasons of 2000 and 2001 on farmer's field at Kangra (HP), to study the effect of biofertilizer (PSB, two levels) and phosphorus fertilization (4 levels) on yield and economics of urdbean (Vigna mungo L.). The study revealed that crop responded favourably to seed inoculation with PSB and phosphorus fertilization (60 kg P2O5/ha) in influencing seed yield. Mean values of two years showed that variety UG-218 was observed to give highest net return/ha and net return/rupee invested of Rs. 12,497 and Rs. 7.5, respectively at its optimum dose, which was worked out to be 86.3 kg P2O5/ha while with inoculation net return/ha and net return/rupee investment at optimum dose were higher over their respective uninoculated treatment.
