Abstract:
The experiment was layout in split plot design with 3 replication. The main plot treatment was 3 varieties viz., Kufri Sinduri (V₁), Kufri Chipsona (V₂) and Kufri Khyati (V₃) and 6 level of integrated nutrient management supply viz., 100% RDF through inorganic fertilizer (N₁), 100% RDF + ZnSO₄ (N₂), 75% RDF + @ 2 tonnes ha^-1 Vermicompost (N₃), 75% RDF + @ 2 tonnes ha^-1 Vermicompost + ZnSO₄ (N₄), 50% RDF + @ 4 tonnes ha^-1 Vermicompost (N₅), 50% RDF + @ 4 tonnes ha^-1 Vermicompost + ZnSO₄ (N₆) kept in sub plot. The crop was sown on 10 November, 2020-21. Seed rate of 20 q ha^-1 was taken for sowing having a spacing of 60 cm x 20 cm. The results revealed that Kufri Khyati produced significantly taller plants of potato having maximum number of compound leaves plant^-1, shoots count plant^-1, dry weight of shoots plant^-1 and crop growth rate, fresh weight of tuber plant^-1, number of tuber plant^-1, which finally resulted in to highest yield and economic returns. Next superior variety was Kufri Sinduri. Amongst the integrated nutrient management the application of 100% RDF + ZnSO_4, caused significantly taller plant height, and higher number of compound leaves plant^-1, shoots count plant^-1, dry weight of shoots plant^-1 and crop growth rate, fresh weight of tuber plant^-1, number of tuber plant^-1, which finally gave the highest yield and economic return followed by 100% RDF (through inorganic fertilizer).
