Abstract: A field experiment was conducted at Crop Research Centre, G.B. Pant University of Agriculture and Technology Pantnagar, Uttarakhand during 2016-17 to evaluate the target yield approach of fertilizer recommendation on yield and economics of cauliflower in Mollisols of Uttarakhand. The experiment was laid out in the Randomized Block Design (RBD) with ten treatments and three replications. The treatments consisted Control (T₁), GRD (T₂), TY₁ (250 q ha^-1) (T₃), TY₂ (300 q ha^-1) (T₄), TY₁ (250 q ha^-1) +10 t ha^-1 FYM) (T₅), TY₁ (250 q ha^-1) +20 t ha^-1FYM) (T₆), TY₂ (300 q ha^-1) +10 t ha^-1FYM (T₇), TY₂(300 q ha^-1) +20 t ha^-1FYM (T₈), 10 t ha^-1FYM (T₉) and 20 t ha^-1 FYM (T₁₀). It is clearly indicated that target yield approach treatments both chemical and under INM mode are significantly superior over general recommended dose (GRD). Economic analysis of this experiment clearly reveals that response of fertilizer and net returns under target yield approach were higher as compared to GRD.
