Abstract: A pot experiment was conducted in 2015 at S.K.N. College of Agriculture, Jobner during kharif season using cowpea as a test crop to investigate the effect of phosphorus management in cowpea grown on saline soils. Three levels each of saline soils (EC 1, 4.0 and 6.0 dS/m), phosphorus sources (SSP, DAP and PROM), and biofertilizers (control, PSB and PSB + VAM), were tested in completely randomized design with three replications. The results indicated that application of soil salinity having EC 1dS/m recorded the maximum and significantly higher microbial biomass P of cowpea over rest of the treatments. Result further indicate that application of phosphorus source PROM recorded the maximum and significantly higher microbial biomass P of cowpea over rest of the treatments. Dual inoculation with PSB + VAM recorded the maximum and significantly higher microbial biomass P of cowpea over rest of the treatments. The results indicated that application of soil salinity having EC 1dS/m recorded the lowest Na/K and Ca/Mg ratio and highest Na/Ca and Na+K/Ca ratio over the rest treatments. Application of phosphorus source PROM recorded the maximum and significantly lowest Na/K, Ca/Mg ratio, Na/Ca and Na+K/Ca ratio over the rest treatment. Dual inoculation with PSB + VAM recorded also lowest Na/K and Ca/Mg ratio and highest Na/Ca and Na+K/Ca ratio over the rest treatments.
