Abstract: An experiment was conducted to study the effects of methods of stand establishment of kharif rice and rabi greengram along with and without hydrogel application in greengram on soil enzyme activities i.e Flourescein diacetate (FDA), phosphatase and dehydrogenase at ICAR-NRRI, Cuttack, Odisha in 2017-18. The experiment was laid in split plot design with three replication. Rice variety shahbhagi was taken in kharif under two methods of establishment i.e. direct seeded and transplanted rice whereas greengram variety IPM 2-3 was taken under conventional tillage, conservation agriculture (zero tillage + residue retention) and paira along with and without hydrogel application and an absolute rice fallow. Results revealed that dehydrogenase and acid phosphatase activity was significantly higher under DSR compared to TPR, whereas no significant difference was noticed for FDA and alkaline phosphatase activity. In greengram, the enzymatic activities varied significantly with different stand establishment methods. Highest enzymatic activity (FDA, dehydrogenase, acid and alkaline phosphatase) was reported in greengram under conventional tillage with hydrogel application. Soil enzymatic activity in rice fallow was recorded the lowest followed by paira greengram. However, on system basis, no significant difference in enzyme activity was recorded.
