Abstract
The object of this experiment was to suggest the optimum autumn sown small forage crops as next forage crops harvested maize in Daejeon area. The field trials was conducted from 2002 to 2004 at Chungnam National University in order to evaluate the dry matter yield and qualities of the autumn sown small forage crops. The experiment was consisted of split plots (main plot : forage crops as rye, barley and wheat, and sub plot 4 harvest stages as boot, heading, milk and dough) design with three replications. The average DM yield for 2 years of rye was higher than that of other forage crops (p<0.01). As stages proceed, the DM yield tended to increase in all forage crops (p<0.01). In chemical composition, they had a difference on forage crops and stages. The crude protein (CP) was higher in barley (p<0.01), but fibrous contents such as NDF, ADF, cellulose and lignin were lower in wheat than in the other forage crops (p<0.01). In Daejeon area, although barley and wheat at milk and dough stages were observed with maximum yield and high quality as autumn sown forage crops, due to late harvesting periods, it is difficult to utilize them as previous forage crops seeded in maize. Based on the result mentioned above, it is concluded that rye harvested at boot to heading stages is the most suitable fur autumn sown small forage crops in Daejeon area. Meanwhile, in order to have the option of nutritional value in wheat and barley, they need to be supplied early maturing and high-yield variety of wheat and barley.
