In order to assess and compare the potential forage production of Crimsonclover with other clover species in different planting dates, an experiment was carried out in split plot arranged in a randomized complete block design with 12 treatments in four replications in Karaj during 2003-2005. In this study pkanting dates were considerd as main plot in four levels (d1: 23 Aug., d2: 6 Sep., d3: 23 Sep. and d4: 7 Oct.) and clover cultivars as subplot in three levels (v1: Crimson clover, v2: Berseem clover and v3: Persian clover). The results of combined analysis of the experiment demonstrated that effects of year, planting date, year × planting date, species, year × species, planting date × species and year × planting date × species (except dry matter yield) were significantly different for fresh and dry matter yield. Mean comparison of planting dates and cloverspecies showed that planting date d1 with 70.20 tha-1 fresh yield, 13.23 tha-1 dry matter yield, and Persian clover with 83.40 tha-1 fresh yield (the same group with Berseem clover), 15.23 tha-1 dry matter yield were the best treatments. Meanwhile, mean comparison of the interaction of planting date × species showed that d3v3 with 90.21 and 18.82 tha-1 fresh and dry matter was the best treatment.
