ABSTRACT
In this present studied poly bag experiment was conducted following complete Randomized block design with 12 treatments and three replications. Polluted soil with supply of fresh water, unpolluted soil with supply of fresh water, unpolluted soil with supply of polluted water. The results of pot culture were reveals that the influence of enzymes activity on biological quality of polluted soil and spinach yield at 30 and 60 DAS in soil was estimated. Significantly highest urease activity was found in treatment T8 (20.24, 17.10 ?g of NH4+ g-1 h-1) at 30 and 60 DAS respectively. The highest dehydrogenase activity was in T8 at 30 and 60 DAS and the lowest activity was found in T3. Acid phosphatase was highest in T3 at 30 and 60 DAS and lowest activity was observed in T8. The highest alkaline phosphatase activity was found in treatment T8 at 30 and 60 DAS and lowest activity was observed in T3. Among all the treatments T8 showed highest urease, dehydrogenase and alkaline phosphatase activity and lowest activity observed in T3. But acid phosphatase activity was highest in T3 and lowest in T8.
Key words :
Dehydrogenase, Enzyme activity, Phosphatase activity, Pollutes soils, Spinach, Urease.
