Effect of biofertilizers on growth and yield of potato

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 (750 g/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).
