Abstract
Field experiment was conducted in black soils in order to study the soil enzyme activities viz., Dehydrogenase, Urease and Phosphatases for maize using Arbuscular mycorrhizal (AM) fungi and Zinc Solubilizing Bacteria (ZSB) in combination with graded levels of ZnSO4. Treatment consisted of two factors viz., Microbial inoculation (M1: control, M2: AM fungi, M3: ZSB and M4: M2 + M3) and graded levels of ZnSO4 (S1: 0, S2: 12.5, S3: 25, S4: 37.5, S5: 50 kg ha-1 and S6: 0.5 % foliar spray @ 45 and 65 DAS) replicated three times in FRBD. The combination of AM and ZSB had enhanced the soil enzyme activities viz., Dehydrogenase, Urease and Phosphatases at vegetative, tasselling and harvest stage of crop growth. However, the Dehydrogenase, Urease and Phosphatases activity was quantitatively increased during tasselling stage due to microbial population, root activities and root exudates higher during tasselling stage. Increased doses of ZnSO4 application had positive effect on the soil enzyme activities viz., Dehydrogenase, Urease and Phosphatases. Combined application of AM and ZSB along with 50 kg of ZnSO4 ha-1 had recorded the highest soil enzyme activities at vegetative, tasselling and harvest stages. However, the dehydrogenase, urease and harvest stage was slightly increased at tasselling stage than vegetative and harvest stage. The application of graded doses of ZnSO4 in combination with AM and ZSB had also increased the soil enzyme activities viz., Dehydrogenase, Urease and Phosphatases, which in turn increased the fertility status of soil.
