The field experiments were conducted during the two successive winter seasons of 2018-19 and 2019-20 at the Vegetable Research Farm under the AICRP on Potato, Department of Vegetable Science, College of Horticulture and Forestry, CAU, Pasighat, Arunachal Pradesh to develop site specific NPK requirements of potato variety Kufri Jyoti on growth and yield attributes. The experiments included seven different treatments of Nitrogen, Phosphorous and Potassium percentage and were evaluated in Randomized Block Design with three replications. Results showed that among the all the treatments maximum plant height was recorded in T3 (150% RDF of NPK), maximum number of shoots per plant was observed in T2 (50% RDF of NPK) and highest tuber yield was recorded (18.15 t ha-1) in 150% RDF. Therefore, it was indicated that in both the years, the yield of potato greatly depend on the dose of fertilizers i.e., NPK application which influenced progressively in terms of producing highest tuber yield and net returns of the crop.
