Abstract
The experiment was conducted at Narendra Deva University of Agriculture and Technology's Main Experiment Station, Department of Vegetable Science, Narendra Nagar (Kumarganj), ayodhya (U.P.), during the Rabi season of 2016–17. The soil in the experimental field has a sandy loam texture. Four replications of a Randomized Block Study were applied to seven treatments. The experimental findings showed that the use of RDF 100 kg P2O5 per ha was found better with respect to promotion of growth, yield and quality parameters of potato. The maximum value on growth characters were also recorded T7 -RDF kg P2O5 ha-1 is better as compare to (T5-90 kg P2O5 ha-1 and T6-120 kg P2O5 ha-1) using in potato variety Kufri Khyati. It was found significantly superior over rest of all the treatments. An application of treatment T7 -RDF 100 kg P2O5 ha-1 in was found to be most effective total phosphorus uptake by plant and tuber (24.31kg h-1) and available phosphorus (13.50 kg h-1). The tuber and plant content of phosphorus was found T7 (.280 %) and (0.156%) and dry matter (18.10%) tuber and (10.86%) in plant for highest tubers yield (388.79 q per ha) and maximum net return Rs. 139062 as benefit cost ratio 1.47 on this dose of phosphorus in the years investigation.
