Chemical Contents of Red Clover Genotypes on Crop Improvement Systems as Livestock Feed

A field experiment was conducted in 2000-2001 at the Research Station of East Anatolia Agricultural Research Institute in Pasinler of Erzurum province in Turkey. In this study, 25 red clovers (Trifolium pratense L.) genotypes were evaluated in terms of chemical contents for animal feeding in the 2 years results. The red clover genotypes were sown in the spring of 2000. The experiment was designed a randomized complete block with replicated 4 times. The genotypes were harvested in 50% flowering once in 2000 and 3 times in 2001. There were significant differences in N (p<0.05), Mg (p<0.05), Zn (p<0.05), Fe (p<0.05), Mn (p<0.01) and Cu (p
