Seeds of Rehmannia glutinosa were sown at intervals of ten days on 10 April, 20 April, 30 April and 10 May, 2004, on the areas divided into three parts of the non-mulched, the mulched with transparent perforated film and the mulched with black perforated film, in order to examine its growth and harvest yields according to the seedtime and film mulching. 1. Tests for Seedtime of Rehmannia Glutinosa and Film Mulching (2004). 1) Measurement of leaf weight per plant on 20 June showed that the heaviest was the group of transparent perforated film of 20 April, grown up to 82.9 g per plant, that is, 74.6 g heavier than that from the non-mulched of 10 May, 8.3 g per plant. It was also found from the investigation on 9 September that the heaviest was the leaf weight of black perforated film of 20 April, increased up to 385.3 g per plant, and 210.5 g weightier than that from the non-mulched of 10 May, 174.8 g per plant. 2) An examination on 20 June indicated that the leaf area of transparent perforated film of 20 April grew the widest up to 126.3 cm2 per plant, and 94.5 cm2 wider than that from the non-mulched of 10 May, 31.8 cm2 per plant. From the test on 9 September, the leaf area of black perforated film of 10 April was found the widest, up to 234 cm2 per plant, that is, 28.7 cm2 wider than that from the non-mulched part of 10 May, 206.2 cm2 per plant. 3) On 20 June, the root weight the group mulched with transparent perforated film of 20 April was found the heaviest, 14.6 g per plant, that is, 11.9 g heavier than that from the non-mulched of 10 May, 2.7 g per plant. On 9 September, the heaviest was the root of black perforated film of 20 April, 205.2 g per plant, and 100.6 g weightier than that from the non-mulched of 10 May, 104.6 g per plant. 4) On 20 June, the most was the root number of the plants from black perforated film of 20 April, 13 per plant, which was 8 more than that from the non-mulched of 10 May, 5 per plant. On 9 September, roots of transparent perforated film of 20 April was the most, 21 per plant, and 11 more than those of the non-mulched of 10 April, 10 per plant. 5) It was found on the whole that the groups mulched with film grew only a little in their leaf weights, leaf areas, numbers of roots, root weights.

Effects of the application of N-P-K fertilizer and organic substances on the growth and yield of chinese foxglove (Rehmania glutinosa) was studied in 2005. some plots of experimental upland were fertilized with three mixture of N-P-K=10-10-20kg/10a, 20-20-30kg/10a, and 30-30-40kg/10a, followed by mulching with black perforated film. Organic substances were mixed with N-P-K=27-27-36kg/ 10a as a basal fertilizer. Amounts of mixtures containing completely decomposed manure and those having moored and fermented manure were 0, 1000, 2000, 3000, 4000kg/10a, respectively. Additional fertilization treatments were conducted with a mixture of N-P-K=14-14-20kg/10a and with N-P-K= 14-14-20kg/10a on 5 July, 20 July, 5 April, 5 September, and 20 September. Conventional farming performed by farmers labor and mechanization integrated cultivation were compared on order to investigate the retrenchment of labour and increases in growth and harvest yield according to the systematization of work for the labour-saving equipment. 1. Effect of Three Major Nutrients(2005) (1)The root weight from N-P-K=20-20-30kg/10a was the weightiest, 238g per plant and that from N-P-K=0-0-0kg/10a a was the lightest, 183g per plant. The difference in root weights between both group was 100g per plants. (2)The number of root from N-P-K=20-20-30kg/10a was most, 22.1 per plant and that from N-P-K=0-0-0kg/10a was the least, 17.3 per plant. The difference in root number between both group was 4.8 per plants. (3)The root weight from 3000kg/10a of manure of full ripeness was the weightiest, 295g per plant and that from non-treated was the lightest, 230g per plant. The difference in root weights between both group was 65g per plants. (4)The number root from 3000kg/10a of manure of full ripeness was the most, 29.8 per plant and that from non-treated was the least, 15.2 per plant. The difference in root number between both group was 14.6per plants. (5)The number of root weight from N-P-K=14-14-20kg/10a of side dressing of 20, July was the weightest, 265g per plant and that from non-treated was the lightest, 230g per plant. The difference in root weight between both group was 35 per plants. (6)The number of root from N-P-K=14-14-20kg/10a of side dressing of 20,July was the weightest, 21.6g per plant and that from non-treated was the least, 15.2 per plant. The difference in root weight between both group was 6.1 per plants. 2. Systematization of Work for the Labour-saving Equipment(2006) (1)The time required for the conventional work was the longest on the whole, 229 min/10a. Cultivation on mechanized group A took 1210 min/10a 980min/10a shorter than conventional one. Group B required 845 min/10a, which was 235 min/10a shorter than group A (2)The rates of mechanization over total labour time were 4207% for the mechanized group A and 36.6% for the group B, while the root weight from the conventional group was heavier than both mechanized groups. the reason of the low late in root weight of mechanized group A was considered as famers lack of skill because they worked with the equipment for the first time. (3)The reason of the better harvest from the conventional area was that famers hands were able together almost all products, while equipment was not able to lift some portion of seed tuber from the gtound. (4)It is suggested as the result that the integrated mechanized cultivation using farm appliances to the utmost should be adopted, since the cost of production for mechanized areas was lower than that for conventional area, in spite of some loss harvest.

Experiments were carried out in 1981 at the experimental farm of An Sung Agricultural Technical College, to determine the ecological responses of peanut cultivars to different seeding date and densities. Cultivars representing three plant types, ie. runner, semi-runner and Spanish types were chosen and planted on May 15 and June 15. Population levels of 10,000 and 20,000 plants per 10 a were studies with each plant spacing of 60×30, 50×20, 50×10cm respectively. The results obtained are summarized as follows: 1. Main stem of the Spanish type was longer than that of the runner type cultivar, planting density had more significant influence than seeding date on the length of main stem. 2. Number of branches to be greater with increased planting density. For the late seeding date, the number of branches decreased significantly more for runner type cultivars than for semi-runner or Spanish. 3. Try weight (per m^2) increased quite rapidly until August 26, then began to fall slightly. Runner type tended to yield more dry weight than Spanish type cultivars did. Increasing plant population resulted in increased dry weight. This weight tended to be less for the early or late seeding dates than for the plots sown on May 15. 4. Dry pod weight increased rapidly until September 7, then began to increase slowly. 5. The pod yield were generally in the increasing order of Spanish, semi-runner and runner type cultivars. Optimum density for runner type was seeds with plant spacing of 60 ×30cm per 10a with highest yield and that form semi-runner and Spanish type cultivarar was 10.000 seeds with plant spacing of 50×20cm.

1.Development of science has mainly accomplished through experiment or test. The science of agriculture has developed through experiment and closely connected with temperature, light, soil, and fertilizer. And the experiments have much examples earring out through field experiment. Therefore, it is considered now in detail about varience of field before experiment. 2.In this experiment, the plants in border rows showed vigorour growing. 3.In the shallow-plowed fields, the growing of the second raws was less vigorour than that of herder rows, but there were no singificant differences betwen the seconed rows and centeral part. Meanwhile, in the deep-plowed hield, the growing of the border row plants was as twist vigorour as that of the 2nd rows, and the central plants were less vigorour than the second row plants in growing. At the same time, it was observed that, in the central part plants, the weight of harvested rice of deep-plowed fields was than that of shallow-plowed fields.

배추는 재배 온도에 따라 수확량과 품질에 많은 영향을 받을 수 있다. 고온 스트레스 저항성 배추품종 육성을 위해 본 연구는 스트레스 저항성에 관련이 있다고 알려진 trehalose 유전자 관련 다형성 마커를 개발하였다. 아라비돕시스 trehalose 합성 유전자와 유사한 총 28개의 배추 EST를 NCBI database에서 찾고 고온에 상대적으로 약한 지부품종과 고온에 잘 견디는 품종인 권심을 대상으로 다형성을 조사하였다. 이 중 10개의 EST에서 insertion/deletion 또는 single nucleotide polymorphism을 발견하여 이를 바탕으로 쉽게 이용이 가능한 10개의 다형성 PCR 마커를 개발하였다. 본 연구에서 개발된 trehalose 분자마커는 앞으로 배추 작물에서 환경 스트레스 저항성과 유전적 연관성을 확인하는데 이용될 수 있고 MAS를 이용한 품종육성에 이용될 수 있다고 기대된다. High temperature stress might affect the yield and quality of Chinese cabbage. In order to develop cultivars resistant to high temperature stress, we developed polymorphic DNA markers for trehalose synthesis genes related to abiotic stress resistance. A total of 28 Brassica rapa ESTs homologous to trehalose synthesis genes of Arabidopsis were found from the NCBI database. The polymorphic DNA sequences were searched between Chinese cabbages - Chiifu, which is relatively susceptible to high temperature stress, and Kenshin, which is tolerant to high temperature stress. Among the 28 ESTs, we found 10 ESTs that have either insertion/deletion and/or single nucleotide polymorphism between the two cultivars. Those polymorphic sites were then targeted for the development of 10 PCR based markers. These molecular markers related to trehalose genes could be used not only to test their relationship with abiotic stress resistance in Chinese cabbage, but also the development of abiotic stress resistant cultivars using MAS.
