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.

이 실험은 견직물의 결함인 방추효과를 좋게 하기 위하여 견포에 Formaldehyde를 작용 시켰으며 이때 사용되는 HCl, CH3COOH, CaCl2, HCHO, NaCO3, NH4OH, NaOH, NaHCO3 양과 반응액의 온도 및 시간의 변경에 따라 달라지는 견포의 W.R 효과를 측정하였다. 그리고 면과 Viscose rayon 포도 견포와 동시에 처리하여 비교시험 하므로서 가장 효율적인 견포의 주름저항성 개선조건을 모색한 결과 아래와 같은 결론에 도달했다. (1) 각 직포의 W.R 효과를 향상시킬 수 있는 최적의 온도는 견이 75℃, 면이 35~43℃이며 Viscose rayon포의 작용은 75℃ 이하에서는 온도와 상관성이 없다. (2) 최적의 반응온도 처리로 인하여 견은 처리전보다 11.0%, 면은 33.4%의 W.R 효과를 향상시킬 수 있었다. (3) 견·면 및 Viscose rayon 포의 W.R 효과는 직물에 따라 최적의 반응시간이 존재한다. 즉 HAC Hydride를 사용한 최적 견은 60~90분, 면은 120분, Viscose rayon은 90분이었으며 HAC Anhydride를 사용한 경과 견은 60분, 면은 120분, 그리고 Viscose rayon은 40분이었다. (4) 최적의 반응시간에 의하여 견은 16.6%, 면은 25.0% 그리고 Viscose rayon은 13.3%의 W.R 효과를 향상시킬 수 있었다. (5) 견과 Viscose rayon 포의 W.R 효과는 HAC Hydride를 사용하는 것 보다 Anhydride를 사용하는 것이 더욱 효과적이었다. (6) 반응정도에 있어서는 HAC Hydride를 사용하는 것 보다 HAC Anhydride를 사용하는 것이 더욱 빨랐다. (7) HCHO의 양에 의한 W.R 효과를 보면 건은 HCHO의 양이 10~14ml 때가, 면은 18ml 때가 그리고 Viscose rayon 포는 14~18ml 때가 가장 좋았으며 이때 견은 처리 전 보다 8.3%, 면포는 21.5% 그리고 Viscose rayon 포는 7.0%의 W.R 효과를 얻을 수 있었다. (8) 최대의 W.R 효과를 위한 최적의 HCl 사용량은 견과 면포가 모두 14m1이며 견은 처리 전 보다 22.2%, 면은 19.5%의 W.R 효과가 향상되었다. (9) 중화제로서 NaHCO3 4.2gr을 넣었을 때 견의 W.R는 83.3%, 면포는 61.1%로 가장 W.R 효과가 좋았다. 그러나 NaHCO3를 더 이상 첨가하는데 따라 W.R 효과는 견·면포 모두 저하하였다. (10) 중화제로서 NaOH와 NH4OH를 첨가하는 경과 첨가량이 증가하는데 따라 W.R 효과도 저하하나 첨가량이 어느 한계점(견 3.3ml, 면 3.3~6ml)을 지나 더욱 증가하면 W.R 효과도 다시 양호하여지는 현상을 볼 수 있었다. 이와 같은 경향은 특히 견과 면포에서 현저 하였으며, 이 결과로 보아 견과 면포는 반응액의 (H+)을 전부 중화시키고 남은 NaOH와 NH4OH의 잔여(OH-)하에서도 Formaldehyde와 작용할 수 있지 않는가 추측된다. (11) 견포는 Curing 온도가 비교적 낮을 때 W.R 효과가 좋았고 면포는 높을 때 좋았다. (12) 이 실험의 결과 견포의 W.R를 94%까지 (처리전보다 22% 증가)향상시킬 수 있었다는 점으로 보아 앞으로 견포의 W&W 성을 개선할 수 있는 가능성을 충분히 보여주고 있다. This experiment is to improve the wrinkle recovery (W.R.) of silk fabrics. The silk fabrics is creased very well, and the crease is the serious defection of it. This experiment is to improve the nature by use of formaldehyde on fabrics. The reagents used were HCl, CH3COOH, CaCl2, HCHO, Na2COs, NH4OH2, NaOH and NaHCO3. The silk fabrics was treated, to compare the influence of conditions, by varying the quantities of reagents and the temperature of solution, and the reaction time. The cotton fabrics and the viscose rayon were sunk with the silk at the same condition to be compared the influence. 1) Those of the most suitable temperature to improve for the better W.R. are 75℃ for silk, 35-45℃ for cotton, and no particular temperature under 75℃ for viscose rayon. 2) The W.R. improvements after treated at the temperature of 1) were 11% for silk and 33.4% for cotton. 3) There are the best treating time for every fabrics. They were 60 to 90 min. for viscose rayon when HAC was used for solvent. It took, however, 60min. of the best time for silk, 120 min. for cotton, and 40 min. for viscose rayon when acetic anhydride instead of HAC was used. 4) It was possible to improve 16.6% of W.R. for silk at the most suitable treating time, 25.0% for cotton, and 13.3% for viscose rayon. 5) Acetic anhydride was rather more effective to improve W.R. of both silk and viscose rayon than HAC. 6) Treating time was also shorter in case of using acetic anhydride than HAC. 7) The improvement of W.R. were 8.3% for silk at the 10 to 14 ml, of HCHO the best volume, 21.5% for cotton at 18ml, of HCHO, and 70% of for viscose rayon at 14 to 18ml, of HCHO. 8) The most effective quantity of HCl is 14 ml, for both silk and cotton. The W.R. improvement of silk was 22.2%, and that of cotton 19.5%. 9) The W.R. of 83.3% the best for silk and 61.6% for cotton were gained when 4.2gr. of NaHCO3 brings down the percent of W.R. for both silk and cotton. 10) The more NaOH and NH4OH as neutralizing agents, the less effectivity of W.R. until the quantities of the reagents are reached to a special range which are 3.3ml, for silk and 3.3-6.6 ml, for cotton, and then we can see the W.R. increasing as the quantities of reagents are increased. These facts were evident in case of silk and cotton. We can also see with this fact that the reminder of [OH-] neutralizing [H+] in solution makes it possible to treat formaldehyde on fabrics. 11) Low curing temperature was comparatively better for silk, and high temperature better for cotton. 12) The result of this experiment shows that the Improvement of W.R. for silk was possible to 94% which means 22% W.R. increase compared to the untreated silk. This effect also shows that the improvement to W & W (wash and wear) of silk will be possible.

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 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.

The effects of parasiticides such as Folbex, Acaru, Kerthane, Donga and Sungrim on the control of an external mite Varroa jacobsoni in the honeybees were determined. The colonies used were consisted in 240 Italian and the first cross bees between Italian drones and Anatorian queens. The results obtained were as follows: 1. The control effect of the parasiticides was found to be about 90% with Donga, 70% with Kerthane, 60% with Folbex, 40 to 50% with Acaru, and only under 20% with Sungrim in the mild parasitized colonies. 2. Very few workers were killed from the application of the parasiticides against the mite. 3. The queens were attacked severely by the workers in most of the colonies treated with Kerthane, and sometimes those with Donga parasiticide, although they could be well protected with the queen cage from the worker attacking.

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.
