Abstract: This study was carried out to determine major differences in yield (herbage yield, dry matter yield, biological yield and crude protein yield) response to some Nitrogen (0, 2, 4 and 6 kg da-1) and Phosphorus doses (0, 4, 8 and 12 kg da-1) between Hungarian and Hairy vetch species. The experiment was laid out in a randomized complete block design with three replications. Test results indicated significant differences between vetch species in terms of herbage yield, dry matter yield, biological yield and crude protein yield. The highest herbage and dry matter yield were obtained from Hungarian vetch in fertilized plots (6 kg da-1 nitrogen 4 kg da-1 phosphorus applications). The lowest herbage and dry matter yield were obtained from Hairy vetch in nonfertilizer plots. In terms of biological yield, the highest yield were obtained from Hungarian vetch with 2 kg da-1 nitrogen and 8 kg da-1 phosphorus applications and the lowest yield were obtained from Hairy vetch by control plots. Generally, herbage and dry matter yield responses of vetches were increased by Nitrogen and Phosphorus rates.
