This experiment was carried out to investigate the effect of growth stags on the change of weight and percent of leaf, stem, root and grain in Coix Iacryma L. and their chemical composition. The result. obtained were as follows. 1 . The grass height, leaf length and leaf width of Coix Iacryma L. on the green basis were 224㎝, 58㎝ and 4㎝, respectively. It was found that Coix Iacryma L. was nearly finished to gores by the 25th of July. 2. The ratio of leaf and stem per each Coix Iacryma L. on the green basis was progressively decreased and increased, respectively as the growth stage elapsed. However, the ratio of root per each Coix Iacryma L. was almost constant as the growth stage passed away. On the other hand, in the dried basis the ratio of leaf and root per each Coix Iacryma L. was progressively decreased as the growth stage elapsed. The ratio of stem and grain per each Coix Iacryma L. was progressively increased as the growth stage elapsed. 3. The dry matter content of Coix Iacryma L. was 32% at the beginning of October and among this content, the ratio of leaf was greatly decreased and the ratio of stem and grain was progressively increased as the growth stage passed away. 4. Crude protein content of leaf of Coix Iacryma L. by the growth stage on the dried basis was 20% in June and 11% in October and decreased as the growth stage increased. Crude fiber content of leaf of Coix Iacryma L. by the growth stage on the dried basis was 20% in June and 32% in October and increased as the growth stage passed away. On the other hand, content of crude protein and crude fiber of stem and root has the same tendency as leaf has. In the green basis, crude protein content of leaf of Coix Iacryma L. was 2 to 3% and crude fiber content of leaf of Coix Iacryma L. was 3 to 8%. 5. Content of crude protein and crude fiber of grain of Coix Iacryma L. on the dried basis was 12 to 14% and 16 to 29%, respectively and decreased slightly as the growth stage increased. In the green basis, content of crude protein and crude fiber was 2 to 9% and 4 to 14%, respectively and increased slightly as the growth stage elapsed.

This experiment was carried out to investigate the effect of the level of nigroten, phosphate and potash on the grass height, yield and chemical composition of Coix lacryma L.. The results obtained were as follows; 1. Grass height was affected only by the nitrogen fertilization both 1st and 2nd cutting state and not affected by the fertilization of phosphate and potash and by the interaction of N, P and K. In the nitrogen fertilization, grass height was significantly (P$lt;0.05) higher in the treatment (201㎝) applied to 20㎏ per 10a than in the treatment (194㎝) applied to 15㎏ per 10a. However, there were no differences between treatment applied to 20㎏ per 10a treatment applied to 25㎏ per 10a. 2. Yield of Coix lacryma L. on the green basis was significantly (P$lt;0.01) increased only by the nitrogen fertilization among N, P and K. Treatments applied to 20㎏ and 15㎏ of nitrogen per 10a produced 7315㎏ ad 6190㎏ of green grass, respectively, and treatment applied to 20㎏ of nitrogen per 10a was significantly (P$lt;0.01) higher in the yield of green brass than the treatment applied to 15㎏ of nitrogen per 10a. However, there were no significant differences between treatment applied to 20㎏ of nitrogen and treatment applied to 20㎏ of nitrogen per 10a. 3. In the chemical composition of Coix lacryma L. dry matter was not affected by the fertilization level of N, P and K. However, content of crude protein was progressively increased by the increase of fertilization level of N, P and K. On the other band, other chemical composition except dry matter and crude protein also were not affected by the fertilization level of N, P and K. 4. According to the results of this experiment, it may be concluded that the moderate level of N, P and K per 10a. was 20㎏, respectively, for the increase of yield and nutritive value of Coix lacryma L.

This experiment was carried out to investigate the effect of seeding time and cutting stage on the grass height, yield and chemical composition of Coix lacryma L. The results obtained were as follows; 1. In the grass height according to the cutting stage, grass height was highest (130.9㎝) in the treatment sowed on May 25 in 2nd months after seeding and was highest(195.5㎝) in the treatment sowed on May 5 in 3rd months after seeding and was highest (189.4㎝) in the treatment sowed on April 15 in the heading stage. On the other hand, grass height was sharply decreased as the seeding time was late in the 2nd and 3rd cutting stage. 2. The heading stage of Coix lacryma L. was on July 20 in the treatment sowed on April 15 and was on September 2 in the treatment sowed on June 25. However, the heading stage in other treatments was during August. 3. Yield was highest (5100∼6500㎏) in the treatments sowed on April 15 in 2nd and 3rd months after seeding. In general the treatments sowed on June produced greatly less amount of yield(2800∼3300㎏) than the treatments sowed on April or May(4300∼5500㎏). Therefore, it may be concluded that the Cois lacryma L. should be sowed not later than beginning of May in the southern parts of Korea. 4. In the chemical composition of Coix lacryma L. at the green basis, moisture content showed generally 75 to 80%. The content of crude protein was 1 to 3% and snowed highest from April 15 to May 5. The content of crude fiber was 4 to 11% and increased as the seeding time increased. However the content of ether extract, ash and NFE was not greatly affected by the seeding time.

This experiment was conducted to determine the effect of fertilizer application on the yield and feeding value of the Korean wild grasses through April to December, 1969. The results obtained were as follows: 1. The heading stage of the various warm season grasses ranged from late July to mid September for the first year after sowing. However, Silsaepul(Calamagrostis arundinacea) and Gaueksae(Eulia apecicsa) did did not head. 2. The plant height was heigher as the fertilizer application was increased. Through a cutting period, the plant height ranged from 50 ㎝ to 90 ㎝ and the hay percentage of the grasses at each cutting stage varied from 22% to 25%, exclusive of Barengi (Digitaria sanguinalis). 3. The significantly more grass yields were observed in the fertilizer application plots than in the non-fertilizer application plot. The grass yield at the first cutting was increased significantly due to the fertilizer application. The effect of fertilizer application on the grass yield was decreased at the successive cutting. In total grass yield, each species showed the following order of high yield to low: Barengi (Digitaria sanguinalis), Sae (Arundinella hirta), Gueryong (Eargrostr`s ferrugines), Sugueryong (Pennisetum japonica), Nadogirumsae (Andropogen micranthus), and orchard grass. 4. In the chemical composition of the grasses, the contents of crude protein was increased as the level of fertilizer application increased in the fertilizer application plots. 5. Hay production cost of some Korean Wild grasses such as Gueryong (Eragrostis ferruginea): 6.80 Won, Barengi (Digitaria sanguinalis): 7.00 Won, Sae (Arundinella hirta): 7.40 Won, Sugueryong (Eragrostis ferruginea) : 9.00 Won, Nadogirumsae (Andropogon micranthus) : 9.50 Won was found far lower than that of orchard grass: 13.00 Won.

Two Anatoliian queens imported from Canada were crossed with Italian drones. The first cross queens were also backcrossed with Italian drones. Italian colonies used were kept to be almost twice stronger than those of the first cross or back cross throughout the year. The first cross produced significantly (P$lt;0.05) more honey than Italian or back cross on the bee pastures such as acacia, chestnut and lespedeza except for rape. However, there was no significant (P$lt;0.05) difference between Italian and back cross in the honey yield. The heterotic effect by the first cross over Italian for the yearly honey yield per 10,000 bees was 1.2㎏., which amounted to about 70% of the total yield by the same number of Italian bees.
