Description
The experiment was carried out to determine the optimum cultivars and effects of planting date on growth, forage yield and nutritive value of spring sown oats (Avena sativa L.) at the middle mountainous area, Namwon, NLRI, Korea, 1998. The cultivars used in this study was Cayuse, Swan, Foothill, Cashel, Martlock and Winjardie, and the planting dates were 9, 14, 19, 24 and 29 March, and all the forages were harvested on 9 June. Swan among spring oats was the earliest heading type (21 May), and then Martlock (25 May), Winjardie (27 May), and Foothill was the latest (14 June). Dry matter yield was not significantly different (P> 0.05) among six spring oats, except Martlock. Nutritive value was higher in late-maturing cutivars than those of early-maturing types. As the planting date was earlier, the heading date was shortened, and the forage yield was tended to increase. In conclusion, spring oats can be successfully produced by seeding of early March using early-maturing cultivars for more forage production, hay-making during late May, and planting of subsequent forages at the mountainous area in Korea.
