In order to study and compare dierent crop rotations based on wheat in case o quantitative and qualitative perormance, economy, soil ertilization and variations on weeds populations, pests and diseases an experiment was conducted at Agricultural Research Station o Gonbad in years 2005-2010. Treatment levels were 6 type o crop rotation consisted o: 1-wheat-wheat, 2-wheat-canola, 3-wheat- chickpea, 4-wheat- cotton, 5- wheat- watermelon and 6-wheat- sunlower, arranged in an RCBD with 3 replications. Plot dimensions was 9Χ20(180m2) with 2 meters between plots and 6 meters between Reps distances. Selection o crop rotation was based on dominant crop(wheat) o the region. All plot treated by wheat planting on initiation and end o the experiment. Data obtained was analyzed using -test and means was compared applying DMRT. Results revealed that eect o rotation was signiicant on ertile spike No/m2, seed No/m2, 1000seed weight, grain yield, straw yield and harvest index. Highest and lowest seed yield o wheat obtained on 3rd and 6th rotations, respectively. Key word: rotation, wheat, systems, grain yield
