Some growth response after clipping of orchard grass (Dactylis glomerata L.) under several soil moisture levels were investigated. The results were as follows: When the soil moisture was deficit, the contents of nutrients and water in the plants were so decreased that growth after cutting was pool. Consequently, after several cuttings the yield decreased more severely. The same tendency was observed in the excess humid condition. Water utilization of the plants under such conditions was unefficient. Under favorable condition of soil moisture, the contents of nutrients and water in the plants increased, so stubble and root reserves became greater, and therefore the regrowth after clipping was vigour and the yield of dry matter and protein increased. Moreover, the water use efficiency was high.
