AB The nutrient cycle and organic matter decomposition are catalyzed by soil enzymes. In thisstudy, enzymatic activities of catalase, dehydrogenase, alkaline phosphatase, and urease are studied insoils amended with compost (C), moss (M), or biochar (B) and irrigated with heavy metal-contaminatedwastewater (HM-CW), when Nicotiana alata L. and Petunia hybrida L. was grown in pots. The irrigationof HM-CW reduced the soil enzyme activities. However, combined used of 5% M+C+B, results inthe improved soil enzyme activities. In case of N. alata and P. hybrida, catalase activity was 222.03 ±9.24 and 402.34 ± 10.48 mg KMnO4 g-1 soil h-1, respectively, with M+C+B, which was up to 94%higher than non-amended treatment. Similarly, the M+C+B treatment also showed higher activity fordehydrogenase i.e., 180.24 ± 6.95, and 156.79 ± 8.31 μg TPF g-1 soil h-1 for N. alata and P. hybrida,respectively, that were 73% and 49% higher than non-amended treatment. Alkaline phosphataseproduction (μg p-nitrophenol g-1 soil h-1) for N. alata with M+C+B was 40.10 ± 1.92 and with C+Bwas 38.41 ± 2.00, while for P. hybrida with M+C+B was 39.33 ± 2.05, which is signifi cantly higheras compared with the non-amended treatment. Urease activity at M+C+B application in soil withP. hybrida was 83.22 ± 5.54 mg urea g-1 soil h-1, which was much higher than that of N. alata. In generalenzyme activity enhanced in the soil with N. alata or P. hybrida along with soil amendments. It showsthat application of these organic amendments individually or in combination with N. alata or P. hybridaincreased enzyme activities possibly through affecting soil nutrient dynamics
