Abstract:

The field experiment was conducted with maize during kharif on a sandy loam soil at College Farm, College of Agriculture, Rajendranagar, Hyderabad. The experiment was laid out in Randomized Block Design with 13 treatments, each replicated thrice. The urease and dehydrogenase activites in soil were assayed and the results showed an increasing trend in enzymatic activities with the age of the crop and exhibited highest activity at tasseling stage and thereafter the activity decreased towards maturity and harvest. Urease activity at vegetative, tasseling and at harvesting stage of maize was significantly higher, the activities being 43.27, 55.30 and 34.15 μg of NH4+-N released g-1 soil 2h-1, respectively followed by T13 (75 % RDF + SV4 @ 6 t ha-1). Similar results were also recorded of dehydrogenase activity at vegetative, tasseling and at harvesting stage of maize.
