Abstract

Field experiments were conducted during 1999-2000 and 2000-2001 to assess the efficacy of biofertilizers on growth and yield of potato. The results revealed that 100% N and P + soaking of seed tubers in solution containing 1% urea and 1% sodium bicarbonate + Azotobacter and Phosphaobacteria increased plant height at 45 and 75 days, yield of tubers (750g/plant) and total yield (271 q/ha). However, maximum number of tubers (8.89)/plant were obtained with 75% N and P + treatment of tubers with Bacillus (Strain M1).
