Impact of tillage practices and weed management options on soil enzyme activity viz., dehydrogenase activity (DHA), soil urease activity (SUA), acid phosphatase activity (AcPA), alkaline phosphatase activity (AlPA), fluorescein di-acetate (FDA) and β-galactosidase activity (β-GaA) at 30 DAS of maize (5th crop cycle). Means having distinct letters demonstrate significant variances between the treatments at 5% probability level (Tukey’s HSD test) and means having the same letters indicate no significant variances among the treatment means at 5% probability level. Refer to Tables 1 and 2 for treatment details.
