Comparison of quantitative and qualitative forage yield of different Berseem clover (Trifolium Alexandrinum L.) Varieties

In order to investigate and compare the cultivars of the Berseem clover from the point of yield quantitative and qualitative forage yield, a field study was carried out in 2008-2009, in the form of random complete blocks design using time dependent split plot method (cultivar as the main plot and different harvest stages as sub plot) using thirteen variants in four times and three cuttings at Seed and Plant improvement institute in Karaj. The result of variance analysis for mean cuttings showed that from the point of quantitative traits in fresh yield and dry yield and from the point of qualitative traits in percentage of protein, the effect of harvest by cultivar were significant at the level of one percent. Also the result of mean comparison showed that the highest fresh yield and dry yield and protein percentage, were obtained as 27.38 and 6.68 ton per hectare and 27.63 percent respectively for cultivar Elitt-2 in mean three cultivar. Therefore based on the results, Elitt-2 and Tolidi-e-dezfoul cultivars are appropriate and can be recommended for Karaj metrological conditions compare to other cultivars.
