Site Specific NPK Requirements of Potato

Abstract

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 T 3 (150% RDF of NPK), maximum number of shoots per plant was observed in T 2 (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.
