A pot experiment was performed to determine the effect of metribuzin amended with different fertilizers (NPK and vermicompost) on the availability of ammonium nitrogen, phosphorus, potassium ( NH 4 + -N 2 , P, K) and Cu, Mn, Zn and Fe with different concentrations of metribuzin (100, 175 and 250gai.) in Aligarh soil. Pots were also filled with recommended rates of NPK and vermicompost under wheat plants. Among the herbicide concentrations metribuzin @175 gai. proved beneficial as compared to

While the use of NPK and vermicompost proved better in enhancing the nutrients , which may have exerted a positive effect on wheat yield as compared to herbicide use only. Vermicompost increased the micronutrients the most.
