The Site Specific Nutrient Management (SSNM) provides the field specific recommendations in a cost effective and precise manner. A field experiment was done at National Wheat Research Program (NWRP), Bhairahawa, Rupandehi, Nepal during 2019- 20 to evaluate the site specific nutrient management approaches in order to enhance wheat productivity. The SSNM dose was determined at NWRP by using omission plot techniques. The calculated SSNM dose (148:65:71 N: P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O kg ha<sup>-1</sup>), was compared with SSNM + Zn + B, (148:65:71:5:1 N: P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O Zn : B kg ha<sup>-1</sup>), Research recommended dose (RRD, 150:50:50 N: P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O kg ha<sup>-1</sup>); National recommended dose (NRD, 100:50:25 N: P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O kg ha<sup>-1</sup>), Nutrients expert dose (NED,110:50:73 N: P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O kg ha<sup>-1</sup>), and farmers dose (FD, 80: 40:15 N: P<sub>2</sub>O<sub>5</sub>:K<sub>2</sub>O kg ha<sup>-1</sup>) in a RCB design with four replications. The data on growth, yield attributes and yield were collected and analyzed using Genstat Statistical package. Results showed that research recommended dose (RRD) along with SSNM dose and SSNM +Zn +B were statistically similar (p&gt;0.05), but these treatments were comparatively superior over rest of the treatments for yield attributes and yield. Hence it can be concluded that wheat yield can be improved through adoption of SSNM and RRD of fertilizers at Bhairahawa condition.</p> ER -
