This experiment was carried out to evaluate the effect of nitrogen fertilization on the rate of growth and the accumulation pattern of total water-soluble carbohydrates and crude proein in orchardgrass cv. potomac before and after winter. Plants were grown in the pots under different levels of nitrogen fertilizer (3㎏, 6㎏ and 10㎏ per 10a) from 21 September, 1979 to 25 April, 1980 at experimental field of Chonnam National University in Kwangju. The resultes obtained were as follows: 1. Plant heights before winter were increased continuously and reached its peak an about December 5 with the average temperature of 5℃ and then decreased. However, plant leaves, tillers and dry matter in the shoots increased until the end of December, below average temperature of 5℃. 2. The total water-soluble carbohydrates (TSC) in the basal tissue before winter accumulated until the end of December, below average temperature of 5℃. The reserved carbohydrates in the basal tissue after winter decreased when new leaf after the start of plant growth emerged and then increased with morphological development. But the content of TSC decreased again after emergence of tiller and then increased. Crude protein content in the basal tissue both before and after winter decreased as plants aged.

The experiment was carried out to evaluate the effect of top-dressing before and after cutting on the rate of regrowth and the changes of carbohydrate, nitrate and crude protein contained in the samples after cutting of Orchardgrass. Plants were grown in the fields from April 8 to July 12, 1979 The result obtained were as follows. 1. The increase of dry matter was delayed by the cutting, but in the latter term of growth the increasing rate of dry matter in cut shoots was higher than that in uncut shoots. 2. Cutting resulted in a temporary decrease of total water-soluble carbohydrate (T. S. C.) and nitrate content in the shoots while the crude protein content tended to increase temporally. Similar trends were observed when the plants were left intact with top-dressing. 3. The period of recovery to initial stands after cutting about 4 - 5 weeks was in terms of dry matter and total water-soluble carbohydrates. 4. The top-dressing applied simultaneously with the cutting was more effective to stimulate regrowth than that applied after cutting, however, both of the simultaneous and after cutting application were still better than application prior to cutting.

The crude protein content of Korean native reed was highest in the initial stage, decreased gradually as the growth progressed. Crude fiber content decreased in a manner opposite to that of crude protein. Dry matter digestibility determined by in vitro method was highest during May and decreased gradually as the growing stage progressed. The contents of mineral elements and amino acid show a low level. There was a significant positive correlation (p$lt;0.05) between in vitro dry matter digestibility and the content of crude protein, and was a significant negative correlation (p$lt;0.05) between in vitro dry matter digestibility and the content of crude fiber or that of ADF.
