A field experiment was conducted at Research Farm, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, India to study the productivity and profitability of soybean under site-specific nutrient management. The experiment was laid out in randomized block design comprising of three replications and seven treatments including N43P43K50, N43P43K0, N43P0K50, N0P43K50, N20P60K40, Farm yard manure (5t/ha) and N0P0K0. Experimental site was silty clay loam in texture, acidic in reaction, low in available nitrogen, and medium in available phosphorus and potassium. The highest seed yield (1840 kg/ha), harvest index (38.5%), yield gap over N43P43K50(919kg/ha in T7), net return (42234 Rs/ha) and benefit cost ratio (2.25) was recorded at N43P43K50(SSNM). Omission of nutrients significantly reduced yield and monetary returns while it enhanced yield gap. The lowest seed yield, harvest index, net return and benefit cost ratio was recorded in absolute control treatment (N0P0K0). Site specific nutrient management (N43 P43 K50) proved to be the best treatment in enhancing the yield and monetary returns of soybean. The recommended dose of nutrients (N20P60K40) and farm yard manure @ 5t/ha proved to be the second and third best treatment, respectively.
