The experiment was to study the distribution of soil enzyme L-asparaginase in the vegetable growing soils of Ranga Reddy district of Telangana state. since usage of herbicides and pesticides has become inevitable in this area, hence a study was conducted to assess the enzyme activities in the soils. For the assay forty soil samples were collected, which were assayed for enzyme activity and they were correlated with the physico chemical properties of soil. The enzyme L- asparaginase activities of the surface soils expressed as µg of NH4+ released g-1 soil h-1 ranged from 1.4 to 3.5 with an average value of 1.97 from soils varied in texture from clayey to sandy loam. The pH ranged from 5.7 to 8.9, electrical conductivity from 0.1 to 1.23 dSm-1 and organic carbon from 0.13 to 1.48 %. The available N varied from 201.5 to 472.5 kg ha-1. The available P2O5 status in the soils varied from 11.6 to 79.1 kg ha-1. The range of available K2O ranged from 118 to 411 kg ha-1. These results showed that soil samples collected exhibited a wide variation in their properties. They are slight acidic to alkaline in reaction and non – saline in nature.
