This study was carried out to determine some quality characteristics of Gelemen clover (Trifolium meneghinianum Clem.) during budding, flowering and pod setting periods. In the study, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), potassium (K), phosphorus (P), calcium (Ca), magnesium (Mg), condensed tannin (KT), total phenolic (TP), total flavonoid (TF), radical scavenging activity (DPPH) contents were determined. The highest CP was in the budding period (17.78%) and the lowest was in the seed setting period (12.29%). The average K, P, Ca and Mg contents of Gelemen clover were 1.75%, 0.38%, 1.18% and 0.28%, respectively. The highest CT was determined in the pod setting period with 1.93%, and the lowest was in the budding period with 1.06%. The average TP, TF, and DPPH contents of the plant during budding, flowering and pod setting periods were 19.08 mg GA g^-1, 162.71 mg QE g^-1, 162.71 mg QE g^-1, and 67.72%, respectively. As a result, the budding and flowering period of showed superior performance compared to the pod setting period in terms of the quality traits. The secondary compounds determined in the plant were sufficient for animal health and nutrition. In addition, the traits identified in the plant will shed light on future studies.
