Abstract: This study is based upon the assessment of performance of Customized Fertilizer (CF) on potato crop in Eastern region of India. The treatments were control (No fertilizer application), five different graded doses of customized fertilizers (50%, 75%, 100%, 125% and 150% CF dose) and recommended dose of fertilizer. Highest Plant height (54.6 cm) was recorded in treatment 125% CF dose followed by treatment 150% CF dose. Highest number of branches plant^-1 (6.67) and number of effective branches plant^-1 (5.50), tuber length (8.27), tuber plant^-1 (9.03), tuber weight (163.23 g tuber^-1) and tuber yield (23445kg ha^-1) were recorded in 150% CF dose. Net return and B: C ratio was highest in 150% CF dose over all the treatments. Available N was significantly increased in the treatment 150% CF dose over initial. Available P₂O₅ was significantly increased in the treatment 125% CF dose while available K₂O was significantly increased at all application of customized fertilizer over initial.
