| Abstract | ||
| To investigate the effect of rotation on wheat yield and to determine the economic value of crop rotations, eight rotation treatments that had conducted in Jolge-e-Rokh Agricultural Research Station during 2006 - 2010, were evaluated economically, using partial budgeting and marginal analysis. Experimental design was, complete randomized block design with three replications. Treatments consisted of eight crop rotation T1: wheat continuous culture, T2: wheat, wheat, wheat, canola, wheat, T3: wheat, sugar beet, wheat, sugar beet, wheat, T4: wheat, potato, wheat, potato, wheat, T5: wheat, potato, wheat, canola, wheat, T6: wheat, sugar beet, wheat, potato, wheat, T7: wheat, forage corn, wheat, potato, wheat and T8: wheat, forage corn, wheat, sugar beet, wheat. Results indicated that pre plant and kind of crop rotation had significant effects on wheat yield in the final year. Comparing mean test indicated that wheat in rotation had significantly better yield than continuous planting (between 21 to 37 percent). In fixed price, T6 rotation(wheat, sugar beet, wheat, potato, wheat) with relative rate of return 90 % and net income 112.99 million rails had the maximum rate of return and profit respectively, and T3 rotation(wheat, sugar beet, wheat, sugar beet, wheat) with 104 million rails net income followed it. Although change in prices led to change in selected treatment, but treatments in this study had the economical replacements and therefore, farm manager will be faced with flexible options. | ||
