  • This study was carried out from 2015 to 2016 to identify the suitable sowing and harvesting dates of summer crops in the mountain of Yeongnam, South Korea. The experimental design consisted of the different sowing and harvesting dates as follows: corn hybrid (Z. mays, Kwangpyeongok) of sowing (May 8, 19, and 27) and harvesting (August 10, 20, and 30); sorghum${\times}$sorghum hybrid (Sorghum bicolor ${\times}$ Sorghum bicolor, SS405) of sowing (May 27, June 19 and June 27) and harvesting (August 10, 20, and 30). In corn hybrid, ear rate and dry matter (DM) yield decreased (p<0.05) with the postponement of sowing date. Otherwise, ear rate and DM yield increased (p<0.05) with the postponement of harvesting date. Crude protein content decreased (p<0.05) with the postponement of sowing date, but neutral detergent fiber content increased (p<0.05). In sorghum${\times}$sorghum hybrid, plant length and DM yield with the postponement of harvesting date increased (p<0.05), while crude protein content with the postponement of harvesting date decreased (p<0.05). This study concluded that sowing corn hybrid in early May and sorghum${\times}$sorghum hybrid in early June then harvest in the middle of August was recommend to increase dry matter yield and feed value.

  • This study aimed to determine the chemical components of different cultivars (Gabjubaekmok, Sangjudungsi, and Godongsi) of persimmon (Diospyros kaki Thunb.) and the effects of maturity. The detected free sugars were fructose and glucose, and glucose levels tended to increase with maturity. Palmitic acid, oleic acid, linoleic acid and stearic acid, and potassium were major components. In the amino acid component analysis, the following were usually present in the following month: glutamic acid in Gabjubaekmok in July, lysine in Sangjudungsi in August, and threonine in Godongsi in October. Vitamin C tended to increase with aging, and fruit harvested in July had the highest total phenolic and flavonoid contents. In the metabolite analysis, there were significant differences among cultivars and with maturity. The major physiological compounds were analyzed using ultra performance liquid chromatography quadrupole time-of-flight tandem mass ($UPLC/Q-TOF/MS^2$) and were citric acid and gallic aicd. As maturity progressed, citric acid increased but gallic acid decreased.

  • This study was carried out to investigate the flower yield and quality of Lilium Oriental Hybrids as affected by planting date. In cut flower production experiments, effect of planting date and bulb source was studied in rain shelter houses with 30% shading. Four planting dates compared were May 15, June 5, June 25, and July 15. Bulbs used for cut flower production were either imported or produced domestically. The greatest cut flower yield and quality were obtained from bulbs planted either on May 15 or June 25. Bulbs planted on July 15 produced cut flowers of very poor quality and yield, due to high temperatures during the planting time. Therefore, for planting in July, means other than 30% shading have to be adapted to lower temperature during early growth stage. Although plants from imported bulbs had better growth and cut flower yield as compared to domestic bulbs, there was no significant difference.

  • 적막한 시가 자본주의 사회에서 외로운 행보를 계속한다. 올 상반기에 나온 여러권의 시집은 창조와 파괴의 장소, 그 적막한 생명의 원천을 보여준다. 그러기에 지금이야말로 시의 여백의 시대, 아니 시의 르네상스가 도래할 시기인지도 모른다.
