Abstract: A field experiment was conducted during 2015-16 at ICAR- CPRS, Gwalior M.P. during Rabi season, to judge the effect of different phosphorus levels on growth attributes, physiological parameter and grading of tuber in potato crop (Solanum tuberosum L.). The experiment consisted of 10 treatments with four replications. The results revealed that both farmers practice and application of 120 Kg P2O5/ha through fertilizer produced significantly higher dry matter/plant, tuber dry matter/plant, AGR and RGR and both these treatments were statistically at par to each other. On the other hand 100% P2O5 through FYM recorded significantly higher number of leaves/plant whereas application of 100% P2O5 through FYM recorded minimum number and weight of crack tuber as compared to other treatments. Control treatment recorded significantly higher root length and root shoot : ratio, tuber number and tuber yield under < 25 g while application of 120 kg P2O5/ha through fertilizer was higher in case of total number of tuber (per plot), number of tuber and yield of tuber under 20-50 and 50-75 g. However, number and yield of tuber under <75 g was highest in farmers practice. However, quadratic equation line (Y = 21.748 + 5.489 X – 0.587X2) for inorganic doses of phosphorus resulted in, 116.93 and 63.42 kg P2O5/ha were the optimum physical and economical levels, respectively for getting higher yield of tuber. Therefore, it is concluded that application of 120 and 60 Kg P2O5/ha through fertilizer was the best dose of phosphorus for achieving higher optimum physical and economical productivity, respectively.
