Abstract
This field evaluated the effect of different yields on the drying rate of Italian ryegrass ("Kowinearly", Lolium multiflorum Lam.) hay during the spring season. The experiment was performed at Hwaseong, 2015. The different yields of the plot were selected by growth and development check. Three treatments were 35 t/ha(Y1), 45 t/ha(Y2), and 60 t/ha(Y3). After harvest with conditioner, it was conducted tedding 1/day. It was investigated patterns for changes in moisture content. The changes in moisture content were respectively Y1 from 78.9% to 14.4%, Y2 from 79.1% to 18.3%, and Y3 from 77.9% to 25.5% for 5days. It was no different significantly for changes in moisture content by yields from 1st day ~ 2nd day, But It was different significantly from 3rd day to 5th day. the content of neural detergent fiber(NDF) and acid detergent fiber(ADF) were respectively about 34%, 59%, regardless of yields (P>0.05). Crude protein of Yields Y1, Y2, and Y3 were respectively 6.9%, 8.7%, and 9.4% (P<0.05). The result of this study that the higher yields, the slower it dried. The Quantity is a factor to effect on drying rate.
