This study was conducted in order to determine the effect of different cutting times on the quantitative and qualitative performances of some alfalfa cultivars under Bornova-Izmir-Turkey ecological conditions during different growing seasons of 1997 and 1998. Five different alfalfa cultivars (ABP-987, NS-2011, NS-2022, NS-2020, Pioneer 5715) and three cutting times (late April, mid July and late October) were the factors tested in the study. The two-year average indicated that spring cuttings gave higher green and dry matter yield and higher quality than summer and autumn harvests. There were significant differences among alfalfa cultivars with regard to yield characteristics however no significant qualitative differences, except crude cellulose content were observed.
