Background: In this study, it was aimed to compare Hungarian vetch and oats mixed at different ratios not only in terms of silage quality but also in terms of their economic efficiency. “Anadolu Pembesi” Hungarian vetch variety and “Albatros” oat variety were used as plant material in the experiment. Methods: Research was carried out during the winter of 2020-2021 on a farmer field in the Kızıltepe district of Mardin province (Turkiye). In the study, 100% Hungarian vetch, 100% oat, 70% Hungarian vetch + 30% oat, 60% Hungarian vetch + 40% oat, 50% Hungarian vetch + 50% oat, 30% Hungarian vetch + 70% oat silages were tested. Besides silage quality, input-cost analysis and comparison in terms of economic efficiency were also made in the study. Result: Ph value, dry matter, crude protein ratio, acid detergent insoluble fiber, neutral detergent insoluble fiber, digestible dry matter, dry matter consumption, relative feed value and lactic acid ratio varied between 3.88-4.11; 25.02-29.24%; 12.17-19.64%; 31.34-40.24%; 45.27-55.14%; 57.55-64.49%; 2.18-2.65%; 97.15-132.58 and 1.82%-2.38%, respectively. When all the features are evaulated together, 70% Hungarian vetch + 30% oat silage mixture was recommended due to high crude protein ratio, high relative feed value and lactic acid ratio in between low acid detergent insoluble fiber and neutral detergent insoluble fiber ratios. On the other hand, 50% HVS + 50% OS and 60% HVS + 40% OS mixtures stand out as balanced options in terms of both economic gain and quality. This ratio represents the economic optimum point in roughage production and offers an important alternative in the creation of sustainable feed resources.
