Effect of Seeding Time , Legume Species and Surface Treatment on Legume Establishment , Dry Matter Yield , Quality and Botanical Composition of Grasses in Timothy (Phleum pratense L.) Dominated Pasture at Alpine Area

This study was undertaken to evaluate the effect of legume reseeding on legume establishment, dry matter yield, quality and botanical composition of grasses in timothy(Ph1eum prarense L.) dominated pasture at alpine area. Establishment number and percentage of legume in timothy dominated pasture were increased with spring, red clover(Tr$olium pratense L.) and gramoxone $treatment Dry matter yield of pasture was increased with fall and grazing after overseeding, but, there waq no difference in legume species. Crude protein content(%) of grasses at the first cutting was increased with red clover and paraquat (gramoxone) treatment. Based on the results, it is suggested that spring in seeding time, red clover in legume species and oveneeding after gramoxone treatment are good for effective renovation of timothy dominated pasture at alpine area.
