Background: This research was carried out to determine the silage quality of mixtures of Narbon vetch (Vicia narbonensis) + Italian ryegrass (Lolium multiflorum) planted at different ratios (100:0, 75:25, 50:50 and 25:75) in Şanliurfa province of Türkiye. Methods: The study was carried out in 2022 at Harran University Agricultural Research and Application Area, according to the randomized block trial plan with 4 replications. In the research, quality criteria such as pH value, dry matter ratio, ADF, NDF, crude protein ratio, raw ash ratio, silage odour, structure, colour and Flieg score of silage were determined by labouratory analyses. Result: The highest pH value (5.65) was obtained from 50:50 mixture ratio and the lowest pH value (5.22) was obtained from pure Italian ryegrass. The highest dry matter ratio (35.75%) was obtained from 50:50 mixture and the lowest dry matter ratio (31.07%) was obtained from 25:75 Narbon vetch and Italian ryegrass mixture. The highest ADF value (25.0%) was obtained from pure Italian ryegrass and the lowest ADF value (22.9%) was obtained from 75:25 Narbon vetch and Italian ryegrass mixture with. The highest NDF value (44.8%) was obtained from pure Italian ryegrass and the lowest NDF value (29.3%) was obtained from 75:25 Narbon vetch and Italian ryegrass mixture. The highest crude ash value (12.7%) was obtained from pure Italian ryegrass, the lowest crude ash value (8.2%) was obtained from 50:50 mixture. The highest crude protein value (35.7%) was obtained from 50:50 mixture and the lowest crude protein (27.0%) was obtained from pure Italian ryegrass. It was determined that the 75:25 mixture of Narbon vetch + Italian ryegrass was the most suitable option in terms of digestive efficiency and energy use.
