Forage and Hay Yield Performance of Different Berseem Clover (Trifolium alexandinum L.) Genotypes in Mazandaran Conditions

In order to compare forage and hay yield performance of 10 berseem clover genotypes a complete randomized block design with four replications has been undertaken in 2003 and 2004. Samples of 500 g per plot were selected for measuring of dry weight and dry matter percentages of each cultivar. Fresh forage yield of cultivars were significantly different and cultivar Sacromonte by producing 30.80 t ha-1 in average has been ranked as the first high yielding cultivar position, so that, control cultivar, Karmel, showed as a low yielding cultivar in fresh yield production. With regard to dry weight production, there also were significantly differences among different genotypes. Genotype Sacromonte with 5.07 t ha-1 produced the highest dry weight mainly because of higher fresh yield production; however, results obtained from ratios of dry matter brought position of cultivar Sacromonte from first in fresh and dry weight to fifth in percentage of dry matter. Laura with 20.7% has produced highest percentage of dry matter.
