Analysis of variance of tillage, mulch and saline irrigation on pH_s, EC_e , Walkley and Black oxidizable organic C (WBOC) and KMnO₄ oxidizable N, Olsen’s P and NH₄OAc extractable K , soil microbial biomass carbon and nitrogen (MBC and MBN), microbial biomass carbon nitrogen ratio (MBCN), dehydrogenase (DHA), alkaline phosphatase (AlK), Urease (Ur), α- and β-glucosidase (α-/β glu) and on green fodder yield (GFY) and dry fodder sorghum yield (DFY) and weighted linear soil health index (SHI_RS); * P < 0.05, ** P < 0.01, *** P < 0.001 and NS: not significant (P > 0.05).
