Abstract
The grassland establishment under the forest become important, but it comes with a shade for the grass growing among trees. The objective of this study is to select the proper grass-clover mixtures to several shading degrees. The grass-clover mixtures were grown under full sunlights and shade cloths, which reduce sunlight intensity by 35, 50 and 75%. The various types of mixtures were allocated at each shading degrees with three replications. The productivity of mixtures was the highest under full sunlights, and intermediate with 35% degree of shading and least with both 50 and 75% degrees of shading. The 1st mixture (orchardgrass+tall fescue+Kentucky bluegrass+ladino clover+perennial ryegrass+timothy) showed the greatest yield in all treatments. The crude protein (CP) concentration of all mixtures increased with the higher degree of shading, but no CP concentration difference was observed in mixtures within same degree of shading. The lowest neutral detergent fiber (NDF) and acid detergent fiber (ADF) concentrations and highest relative feed value (RFV) were resulted in the 1st mixture in all treatments. This study indicates that tall fescue, Kentucky bluegrass, ladino clover, perennial ryegrass and timothy can be used as components for mixtures with orchardgrass which is major component for forest-pastures.
