Abstract: An ongoing long-term field experiment established in 1994 under different vegetable cropping system established at the Vegetable Science research farm, CCS HAU, Hisar, India was selected to study the effects of sodic water irrigation, gypsum and farmyard manures on soil available nutrients in soil. The field was irrigated with high RSC (11.5 me/l) sodic water having three levels of gypsum (G0,G1,G2) G0 control,G1=50 % neutralization of RSC,G2 = 100% neutralization of RSC, as well as FYM (F0, F1, F2) (F0 = control, F1= 10 tons/ha, F2 =20 tons/ha) on a sandy loam Typic Ustochrept having 19.6 percent clay and 9.3 Cmol/kg cation exchange capacity in 0-15 cm layer. Results showed that the pH of soil very high under F0G0, and decreased with the use of FYM and gypsum as amendments, however reverse trend observed in Electrical conductivity. Increasing trend of all available nutrients was observed when FYM applied over no FYM application but with the application of gypsum, Available nutrients (N, P, S) content increased in soil but available K content decreased. These results indicate that the combined use of FYM and gypsum improved soil health and maintained the sustainability of the different vegetable cropping system.
