Investigation To Determine A Suitable Rotation For Rain-Fed Wheat In Kermanshah

A Randomized Complete Block Design experiment was conducted to determine the suitable rotation for wheat in Kermanbshah provine. Six crop rotation chickpea-wheat, lentil-wheat, wheat-wheat, fallow-wheat, vetch-wheat, medic-wheat with 4 replications were studied in 2 sites of Sararood Rainfed Research Station. The results of 3 complete rotation periods showed a significant difference in wheat grain yield. Among different crop rotations, medic-wheat rotation was classified in group I and wheat-wheat and vetch-wheat in group II. The remaining treatments varied between these two groups. Chickpea-wheat and lentil-wheat crop rotations were the most suitable from the economic and yield production points of view and are recommended for Kermanshah province.
