This study was conducted to evaluate the influence of seeding rates and nitrogen application on the growth, forage yield, and its components of different vetch varieties under rainfed conditions of sulaimani region during the growing season of 2020-2021. The field experiment was conducted in a split-split plot layout arrangement with a randomized complete block design (RCBD) with three replications. The main plots were fertilizer applications (no fertilization 0Kg N/ha and fertilization 40Kg N/ha), and subplots consisting of five varieties of vetch obtained from Agricultural Research Centre-Sulaimania were (V1(Morrd), V2 (Rook), V3 (Excel), V4 (Clima), and V5 (Namoi)), while sub-sub plots were two different seeding rates (40 Kg/ ha and 60 Kg/ha). The result of this investigation showed that the application of nitrogen fertilizer caused to increase in some growth traits of vetch such as no. of branches. plant-1 , no. of leaves. plant-1 , the weight of leaves. plant-1 and root length, green forage yield, dry forage yield, dry matter%, fresh leaf%, fresh leaves/stem ratio, dry leaf%, and dry leaves/stem ratio. Variety 2 (Rook) gave the highest value for most growth traits, green forage yield, and dry forage yield, but the lowest dry matter% was obtained by this variety, and variety 1 (Moord) was the best among other varieties for forage yield components such as fresh leaf%, fresh leaves/stem ratio, dry leaf%, and dry leaves/stem ratio. By increasing the seeding rate plant height, and weight of leaves. plant-1 , green forage yield, dry forage yield, fresh stem%, and dry stem% were increased but other growth traits and dry matter% decreased. Cluster analysis results indicate the presence of high variability based on agro-morphological traits between five varieties of vetch used in this study thus, the improvement of this crop is possible through the breeding techniques.
