A field experiment was laid out to evaluate the effect of inorganic fertilizer and organic manure (FYM) on vegetative growth and yield of potato (Solanum tuberosum L.) Cv. Kufri badshah. The study was at factorial arrangement based on randomized block design (RBD). Inorganic fertilizer applied as recommended dose of fertilizer (RDF) with simple fertilizer (Urea, SSP and MoP) and organic manure applied as farm yard manure. It was observed that the highest plant height, number of branches, number of leaves and tuber yield (190.15 q ha^-1) was obtained in treatment combination T₈ - @ (N₂₄₀P₁₀₀K₁₅₀ Kg ha^-1 + FYM 10 t ha^-1) and followed by T₇- @ (N₂₄₀P₁₀₀K₁₅₀ Kg ha^-1 + FYM 5 t ha^-1). The treatment combination T_{8 -} (I₂F₂) @ (N₂₄₀P₁₀₀K₁₅₀ Kg ha^-1 + FYM 10 t ha^-1) with highest net profit Rs. (74646.41 ha^-1) and cost benefit ratio (B: C) (1.96).
