This study was carried during the 2018-2019 cultivation period in order to determine yield and yield components and weed and silage quality of some annual legume forage plants in Siirt ecological conditions in the dry conditions of Siirt province. In this study, 10 different legume forage plant species were used as plant material. These are Gap Pembesi (Forage pea), Doruk (Common vetch), Görkem (Narbonne vetch), Tarm Beyazı (Hungarian vetch), Efes-79 (Hairy vetch), Derya (Berseem clover), Native ecotype (Feed beans), Gap Mavisi (Grasspea), Native ecotype (Bitter vetch), Berkem (Fenugreek). The field experiment was conducted in such a way as to have 3 repetitions according to the pattern of random blocks. In the study;  plant height (cm), green herbage  yield (kg ha^-1), hay yield (kg ha^-1), hay yield ratio, silage pH, Lactic acid (LA) ratio, Dry matter intake (DMI) ratio, Crude protein (CP) ratio, Crude protein (CP) yield (kg ha^-1), Acid detergent fiber (ADF) and Neutral detergent fiber (NDF) ratios, Digestible dry matter (DDM) ratio, Relative feed value (RFV) examined the properties of silage Dry matter (DM). According to the research results; 66.17 cm average plant height, green herbage yield 29.530 kg ha^-1, hay yield 7.281 kg ha^-1, hay matter ratio 24.39%, the value of silage pH 4.40, LA of 1.89%, DMI 3.36%, CP 18.32%, CP yield 1.330 kg ha^-1, ADF ratio 27.89%, NDF ratio 35.81%, DDM 67.17%, the value of RFV 174.96 and silage DM ratio 34.53. Considering all the results, bitter vetch and vetch varieties were found to be superior in both yield and quality compared to other varieties.
