In order to study the effect of four nitrogen rates (0,60,90 and 120 kg ha-1) and four P20S rates (0,30,60 and 90 kg ha-1) on grain Yield Barley cultivar Gloria "s" (Jonuob) a field, experiment was Condcted In Behbahan station in two growing season (1994-96). A Factorial design in complete block with foUr rePlicate was used. Combined analysis indicate that the best grain yield releated to (NOP60)treatment that had not significant different with (NOPO) treatment ON final resulte we can recomment that no requirment to use nitrogen when N rate of soil was %9 or larger at sowing date and application 50 kg super Phosphate triple when available of soil was larger than 10 ppm.
