This study was carried out to investigate varietal differences on growth characteristics under the conditions of PE film-mulching and non-mulching in sesame. At maturing stage from 76 to 95 days after sowing, Yangbaeckkae, non-branching plant type, under non-mulching showed larger leaf area index (LAI) than that of film-mulching, while plant height and the number of capsules per plant were similar to those of film-mulching. LAI of Ahnsankkae, branching plant type, under non-mulching was similar to film-mulching, while plant height and the number of capsules per plant were smaller than those of film-mulching. Net assimilation rate (NAR) of two varieties under non-mulching was lower at seedling stage from 25 to 35 days after sowing but higher at flowering stage from 45 to 55 days after sowing. At maturing stage from 66 to 77 days after sowing, NAR and crop growth rate (CGR) of Yangbaeckkae under non-mulching were greater than those of film-mulching, whereas those of Ahnsankkae under non-mulching were lesser than those of film-mulching. Yield under non-mulching was decreased by 7 % in Yangbaeckkae and 33 % in Ahnsankkae compared with that of film-mulching, therefore Yangbaeckkae was more adaptable for non-mulching than Ahnsankkae. Main factors decreasing yield of Yangbaeckkae under non-mulching were small LAI, NAR, and CGR at the stage of young seedling, and small number of capsules at early maturing stage from first flowering to 20 days after first flowering.

The present study investigated the effects of dietary supplementation of peanut shell extract on the growth performance and physiological properties of broiler chicks. Two diet energy levels (Positive and Negative) and four additives (0.0, 0.05, and 0.1% peanut shell extract and commercial antioxidant) were factorially arranged for eight treatments. The overall weight gain of the broilers was slightly improved at 0.05% for the antioxidant treatments regardless of the diet energy levels, but there was no statistical difference among the treatments (p > 0.05). The carcass characteristics of the broilers, such as cooking loss, crude protein content, antioxidant activity, and thiobarbituric acid reactive substances (TBARS) values, were improved by the feeding diets containing the 0.05% peanut shell extract. Furthermore, it was confirmed that the dietary supplementation of peanut shell extract did not have a negative effect on the immune responses of the broilers show by the lack of statistical differences in the liver and bursa Fabricious weight and cytokine level among the treatments. From the economic analysis, dietary supplementation of peanut shell extract significantly influenced the compensatory growth and food efficiency and, in turn, led to a decrease in the duration needed to reach 1.5 kg compared to the control. These results suggest the possibility that the peanut shell extract could be used as a functional feed additive by improving the growth performance and carcass characteristics with no detrimental effects on broilers.

This experiment was performed to analyze variation of growth traits of soybean to determine the information of less sensitive traits under different environmental conditions. Sowing was carried out on June 2 each year and the experimental plot was laid out in three replicates by randomized complete block design with thirty soybean varieties which consisted of 19 cultivars for beancurd and soypaste, 8 cultivars for soy-sprout including 1 landrace, and 3 cultivars for cooking with rice including 1 landrace during the period 2014-2015. The weather conditions during the experimental period were quite different with extremely low precipitation and longer sunshine duration in 2015 than 2014. The variation of characteristics related to growth period such as days of growth, days of maturity, days of flowering and the 100-seed weight was less in spite of different environmental conditions. While the variation of the number of pods per plant was high. Considering growth and seed characteristics like the number of pods per plant, the number of seeds per pod and 100-seed weight which are linked directly to the yield, cultivars such as Shingi, Daewonkong, Danbaegkong, and Daepung for beancurd and soypaste, Pungwon, Haepum and Shingang for soy-sprout and Seoritae for cooking with rice were more stable and could be expected to have high yield in Suwon, the south-central part of South Korea. These results could be useful for the selection of breeding resources to develop cultivars with high stability under changeable weather condition.

요구르트는 유산균을 이용하여 제조한 대표적인 유발효식품이다. 국내 유통되고 있는 요구르트는 약 30개의 업체에서 생산되고 있으며, 최근 당 저감화 정책 실시로 저당제품이 출시되고 있다. 본 연구는 국내 시판되고 있는 액상타입의 요구르트를 수집하여 제품의 일반적인 특성을 조사하였고, pH, 산도, 당도, 점도, 호기성 혐기성 유산균수를 측정하여 기초자료로 사용하고자 하였다. 탈지분유(97%) 및 원유(57%)가 주된 원료로 높은 빈도로 사용되고 있으며, 발효스타터는 요구르트에 100% 이용되고 있으며 주로 수입균주가 이용되고 있다. 당은 sucrose, oligosaccharide, xylitol이 첨가되었고, 그 외 구연산, vitamin C, gum류 등이 요구르트의 기능성과 물성 등을 개선하고자 하는 부원료로 사용되고 있는 것을 확인하였다. 30종의 요구르트의 품질특성을 분석한 결과 pH는 3.6-4.6, 당도는 7.4-21.2%, 총산도는 0.4-0.9%, 호기성 유산균수 7.2-11.3 log CFU/mL, 혐기성 유산균수는 8.0-11.5 log CFU/mL로 분석되었다. 본 연구에서 도출된 시판 액상타입 요구르트의 품질분석 결과는 다양한 소재를 접목한 요구르트 개발의 품질규격설정의 기초자료로 유용 할 것으로 사료된다.
