Effects of harvest time and the growth regulator Alar-85 on seed yield and seed-yield components of red clover (Trifolium pratense L.) were studied. Data were collected from the primary growth (first crop) and from the aftermath (second crop). The second crop outyielded the first crop in one year and yielded the same in another year. Alar-85 shortened corolla tubes in all four cultivars and reduced plant height in three cultivars. It increased seed yields of the second crop of Dollard and Hungaropoli by more than 100%, through increases in seed setting and the number of heads per m 2 .Key words: Red clover, Trifolium pratense L., seed yield, Alar-85, harvest time
