In order to evaluatethe quantitative and qualitative traits of forage legumes under rainfed and supplemental irrigation conditions, a field experiment was conducted using a split plot based on randomized complete blocks design with three replications at the Research Station, Agriculture and Natural Resources Research Center of Kurdistan during growing season of 2012-2013. Main factor was irrigation levels (no irrigation, one time irrigation and two times irrigations) and sub-plots was including legume species (Vica villosa L., Pisum sativum L., Vica panonica L., Lathyrus sativus L.). Results showed that plant height, fresh and dry weight, protein percent, NDF and ADF percent were significantly affected by irrigation levels and legume species. P. sativum had maximum height and L. sativus had the highest fresh weight and protein percent. Maximum NDF and ADF was belonged to V. villosa and V. panonica, respectively. L. sativus had the highest fresh and dry weight of forage in two times and no irrigation levels. Under one irrigation condition, P. sativum in terms of fresh and dry weight of forage, was superior compared to other legumes. Finally, according to the results of this study, P. sativum and L. sativus because of high yield and growth are suitable for planting in environmental conditions of Kurdistan Region.
