Abstract

Application of 100 kg P2O5/ha (100% dose of recommended P) along with PSB inoculation gave highest tuber yield (216 q/ha) which was statistically at par with 100% P (206 q/ha). Application 100% P was statistically was at par with 75% P + PSB (203 q/ha). Higher mean of yield, phosphorus uptake, phosphorus use efficiency and apparent nutrient recovery were observed with seed inoculation with PSB as compare to without PSB. The results of this study indicated the beneficial effects of PSB inoculation on tuber yield and 11 to 18% of recommended dose of P can be saved with the seed inoculation by PSB.
