In: Mansoura University Journal of Agricultural Sciences 2007.v.32(11)Summary: Mean value of grain yield with U fertilizer was slightly higher (3.89 Mg fed-1) than with AS fertilizer (3.54 Mg fed-1) in 1998 season. A significant increase was obtained in grain yield due to PG application. In 1998 season, ∆ increase % was 8.1, 11.3 and 17.3% with PG1 PG2 and PG3respectively. The corresponding values in 1999 were 2.4, 7.5 and 13.7%. However, OM treatments led to slight decrease in grain yield with the two seasons.
