Main Data : The field experiment was conducted to assess the efficacy of nitrogen and phosphorus nutrients, with or without biofertilizers on nutrient content uptake and yield of potato. Application of 160 kg N + 100 kg P₂O₅ 120 kg K₂O/ha and soaking of seed tubers in solution containing 1% urea and sodium bicarbonate Azotobcter and phosphobacteria was beneficial in increasing N and P content and uptake by haulm and tubers of potato and tuber yield, which was closely followed by application of 120 kg N+ 80 kg P₂O₅ 120 kg K₂O/ha+soaking of seed tubers in 1% solution of urea and sodium bicarbonate + Azotobacter and phosphobacteria. Keywords: Potato, Biofertilizers, Nitrogen content, Uptake, Phosphorus content.
