Abstract :

In order to investigate the effect of rotation and two nitrogen fertilizer rates on yield and some agronomic characteristics of Chamran wheat cultivar, an experiment  was conducted  as factorial based on randomized complete block design with four replications in experimental field of agriculture faculty of Ahvaz Shahid Chamran University in 2002. Rotation treatments including wheat-wheat, corn-wheat, sudangrass-wheat, mixed forage-wheat, suger­beet-wheat and sudangrass-rape seed-wheat and nitrogen fertilizer requirement for producing 5 and 7 tons per hectare were considered as experimental factors. The results revealed significant effect of rotation and nitrogen levels on grain and stubble protein yield. The hieghest grain yield was obtained from sugeer­beet-wheat and corn-wheat rotations in nitrogen level for 7 ton per hectare grain production .Nitrogen, phosphorus and potasium uptake amounts had no significant variation under rotation in all treatments. Nitrogen and phosphorus uptake amounts were lower than optimum and potasium uptake amount was optimum in Ahvaz climate condition.
