"Abstract: The effects of metribuzin on some soil enzyme activities (FDAH (fluorescein diacetate hydrolysis), dehydrogenase, acid and alkaline phosphatase alone or combined with fertilizers ( NPK and vermicompost ) were investigated in a pot experiment growing wheat as a test crop. Pots were also filled with recommended rates of NPK and vermicompost under wheat plants. Among the soil enzymes dehydrogenase and FDAH were the least tolerant to the effect of the herbicide, whereas alkaline were the most tolerant one. Metribuzin @ 250 gai. proved deleterious for soil enzymes as compared to other two concentrations of metribuzin @ 100 and 175 gai. While the use of vermicompost as compared to NPK proved superior in enhancing enzyme activities, which may have recorded a positive effect on wheat yield also as compared to herbicide (metribuzin ) use only.
