A pot culture experiment was conducted to study the biological properties of saline soils grown with different cultivars of sorghum during rabi 2015-2016 at Department of Soil Science and Agricultural Chemistry, Agricultural College, Bapatla. Soils of different salinity (1.5, 5, 8 and 12 dS m-1 of ECe) collected from Uppugunduru region were tested using three cultivars (Hytech, Laxmi and Mahalaxmi) in completely randomized design with factorial concept replicating thrice. The salinity levels, cultivars and their interaction significantly influenced the microbial population and enzyme activity. Considerable reduction in microbial population and enzyme activity was observed at the maximum EC tested (12 dS m-1). The interaction between the salinity and cultivars at 30 DAS, flowering and harvest revealed that the bacterial population was highest (15.73, 18.50 and 16.33 X 105 CFU g-1) in the treatment combination of 1.5 dS m-1 x Hytech and lowest (8.87, 10.64 and 9.66 X 105 CFU g-1) in the treatment combination 12 dS m-1 x Mahalaxmi. Similar trends in fungal, actinomycetes population and dehydrogenase enzyme activity were recorded at 30 DAS, flowering and harvest stages.
