To select the best silage type forage, the yield performance, grain percentage, and agronomic characteristics of selected sorghum hybrids (sorghum bicolor (L.) Moench) have been evaluated at Suweon and Kwangju areas. The hybrids used in this experiment were Silo Milo, T-E Silomaker, Pioneer 931, Pioneer 944, FS 251 and Suweon 19 hybrid corn. The experiment was arranged as a randomized complete block design with three replications and undertaken over a period of five months from May to September, 1980 and 1981. The results obtained are summarized as follows: 1. FS 251 and Suweon 19 hybrid corn headed and flowered early than other hybrids, however, Pioneer 931 and Pioneer 944 showed later. 2. Pioneer 931 was found to be a tall and large type hybrid, while FS 251 was a short type one. No diseases were found in all hybrids during the growing season, and only Pioneer 944 showed a little lodging. 3. Average grain percentage to the total forage yield of Suweon 19 hybrid corn was the highest (46.0%), and also those of Silo Milo, FS 251 and T-E Silomaker were high over 30%. However, grain percentage of Pioneer 931 was only 12.6%. There was negative correlation between plant height and grain percentage. 4. Pioneer 931 gave significantly higher forage yield than the control variety, Suweon 19 hybrid corn (p$lt;0.05), and there were no significant differences in forage yield between Silo Milo, T-E Silomaker, Pioneer 944 and Suweon 19 hybrid corn. Dry matter yield of FS 251 was the lowest (p$lt;0.05). 5. The results indicated that Pioneer 931 could be recommended as a silage type hybrid instead of silage corn. Silo-Milo, T-E Silomaker and Pioneer 944 can be grown in the areas where the silage corn is not suitable.

A comparative yield trial has been made on 9 cultivars of grasses, legumes and fodder radish introduced from the Netherlands, with 2 available cultivars N. F. G. perennial ryegrass and Kungjung Chongtae radish as controls at Suweon and Cheju for two years 1978-1979. During the growing season, none of the introduced cultivars significantly outyielded the control cultivar N. F. G. perennial ryegrass, although Barmultra Italian ryegrass and Barspectra westerwolds ryegrass produced 4.6% and 2% more dry matter at Suweon, Barvestra perennial ryegrass and all other cultivars significantly lower than the control. Barmultra Italian ryegrass and Barspectra westerwolds ryegrass produced 12.7% and 3.1% more dry matter than the control cultivar N. F. G. perennial ryegrass at Cheju, but the former was only significantly higher than the control cultivar. Data were also collected on the percentage distribution of yield of ryegrasses and on susceptibility to stem rust.

An experiment was carried out to determine the effects of liming, Rhizo-Keto and Rhizo-Kote plus Apron seed coating treatments on the emergence, establishment, seedling vigor, nodule formation, winter survival, and forage dry matter yield of alfalfa (Medicago saliva L.). The experiment was conducted using a split-plot design with liming as main plots and seed coating treatments as subplots. Liming significantly (P$lt;0.05) enhanced the emergence and establishment of alfalfa seedlings compared to non-liming, but did not improve winter survival. Rhizo-Kote and Rhizo-Kote plus Apron seed treatments significantly (P$lt;0.05) enhanced the emergence and establishment of alfalfa seedlings compared to untreated raw seed, however, winter survival was not improved by the seed treatments, Rhizo-Kote plus Apron seed treatment did not improve the emergence, establishment, and winter survival of alfalfa seedlings compared to the Rhizo-Kote seed treatment. Liming did not improve the seedling vigor of alfalfa, but the Rhizo-Kote and Rhizo-Kote plus Apron significantly (P$lt;0.05) enhanced the plant height, nodule number, and dry weight of alfalfa seedlings compared to the raw seed, however,no significant difference was found between the Rhizo-Kote and Rhizo-Kote plus Apron seed treatments for the seedling vigor of alfalfa. Liming, Rhizo-Kote and Rhizo-Kote plus Apron treatments did not increase the nodule formation and forage dry matter yield of alfalfa in the year of following seeding. There were no significant interactions between seed coating treatment and liming for the emergence, establishment, seedling vigor, and forage yield of alfalfa. Based on the results of this experiment it is concluded that liming and Rhizo-Kote seed coating can improve the seedling growth of alfalfa, but those treatments have no consistent effect on forage yield in the year of following seeding.

This experiment was conducted to compare the effects of glutamic acid fermentation residue (G.A.F.R) and urea as a source of nitrogen on the growth, production and chemical composition of pasture species over a period of year from Sept. 7, 1977 to Sept. 24, 1978. Five different fertilizing rates of urea and G.A.F.R arranged according to the amount of nitrogen; 0, 15 ㎏ N/l0a as urea 9, 15 and 21 ㎏ N / l0a as G.A.F.R. The results obtained are summarized as follows: 1. The seedling establishment of pasture species was greatly depressed by urea and G.A.F.R fertilization. As the amount of G.A.F.R fertilizing rate increased the seedling establishment of pasture species depressed proportionately. 2 . Winter hardiness of pasture species decreased when the fertilizing rate of G.A.F.R. increased and urea was a little more effective than G.A.F.R at the same amount of nitrogen except for Italian ryegrass. 3. Dry matter yield of pasture species per l0a was increased significantly with urea and G.A.F.R. (p$lt;0.01) 4. The botanical composition of grasses was increased with urea and G.A.F.R, while ladino clover was decreased 5. The crude protein content of pasture species was increased markedly with urea, and G.A.F.R, while nitrogen free extract was decreased. 6. The results obtained from this experiment indicated that G.A.F.R, as a nitrogen source was equally or more effective on the growth, production and chemical composition of pasture species compared with urea.

This experiment was carried out to evaluate the effect of nitrogen fertilization on the rate of growth, and the changes of carbohydrate, nitrate-nitrogen and crude protein content contained in the samples after seedling establishment of orchardgrass. Plants were grown in the pots fertilized light and increasing nitrogen, till dune 13, 1979 after sowing on the, April 12, 1979. The result, obtained were a, follow; 1. Dry matter yield in the pots fertilized increasing nitrogen way more than that in light nitrogen with aging. The liberal use of nitrogen fertilizers after seedling establishment stimulated the growth of orchardgrass in the early growing stage. 2. The convent of total water-soluble carbohydrate, (T. S. C) m stubble, leaves and shoots temporally decreased following nitrogen fertilization after seedling establishment, after which it again increased, and that of plant parts in the pots fertilized increasing nitrogen decreased more than that of plant part; in light nitrogen. 3. Stubble were higher in the content of total water-soluble carbohydrates (T. S. C.) than leaves, and the content of total water-soluble carbohydrate, (T. S. C.) of plant party decreased by tillering. 4. Nitrate-nitrogen content decreased following nitrogen fertilization and gradually increased, however, it was shown again trend, decreased at the end of experiment. Crude protein content rapidly increased immediately following nitrogen fertilization, however, it gradually decreased.

This study was designed to find out the reasons of the slow growth of Dystaenia takesimana in its early stages and ultimately to promote early growth. To study the growth characteristics of this species, the seedling growth rate, the effect of growth regulators, chlorophyll content in fresh leaves and the relationship between soil characteristics and seedling growth were examined. The results obtained are summarized as follows: 1. The root growth of Dystaenia takesimana was very poor in the early stage and the growth curve of root was quite different from that of alfalfa and orchardgrass. 2. The chlorophyll content of Dystaenia takesimana was very low in the seeding year compared with other pasture plants. 3. With the treatment of gibbereilic acid the plant height of Dystaenia takesimana was considerably promoted, however, this kind of treatment could not be a practical method at the field level. 4. The growth of Dystaenia takesimama was closely related with organic matter, boron and moisture content in the soil. 5. As the results of this study, it was suggested that t11e early growth of Dystaenia takesimana could be promoted 1) by shortening the period of germination with the high temperature treatment (40℃) of the seeds is pre-germination and 2) by the application of compost to the field, and selection for good seminal root development is important to improve establishment.

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.
