Abstract: An experiment was conducted on standardization of site specific NPK requirements for potato variety Kufri Jyoti at HRES, Hassan for three years during Kharif season of 2015-18. The research was initiated with seven treatments viz., T1-RDF -50 per cent NPK, T2-RDF-100 per cent NPK, T3-RDF-150 per cent NPK, T4-without N, T5-without P, T6-without K and T7-without NPK as check. An experiment was laid out in RCBD with three replications by adopting 60 cm x 20 cm spacing. The fertilizers were applied based on the recommended dose of fertilizer of 75:75:100 kg NPK per ha with FYM at 25 tons per ha. The results indicated that, treatment with RDF at 150 per cent of NPK fertilizers resulted significantly highest total tuber yield of 15.86 t/ha with B: C ratio of 1.61 followed by RDF at 100 per cent NPK recorded 13.75 t/ha and B: C ratio of 1.49 as compared to other treatments. Therefore it was indicated that application of higher dose of 150 per cent NPK, crop was responded progressively in terms of producing highest tuber yield and net returns.
