Four seed vetch (Vicia tetrasperma), a biennial native leguminous plant, was used for a cover crop with different quantity of sowed seeds. Weed suppression and yield were evaluated for the red pepper cultivation in the following year of the vetch seeding. Seeding of 1.0, 2.0, 3.0, 4.5, and 6.0 kg 10 $a^{-1}$ suppressed weed occurrences until late in the growing season of the red pepper. Consequently, red pepper in the cover cropping system with seeding of 3.0, 4.5, and 6.0 kg 10 $a^{-1}$ had a similar yield to the conventional red pepper. The ideal seed rate in four seed vetch was 3.0 and 4.5 kg 10 $a^{-1}$ in terms of reducing weed occurrence as well as increasing growth and yield in red pepper.

To screen several promising red pepper cultivars, may be adaptable to organic cultivation conditions, seventy six F1 hybrids commercial and eight local purebred red pepper cultivars were tested. Comparing the infection rate of phytophthora blight between commercial (F1 hybrid) and local (Purebred) cultivars, average infection rate of commercial cultivars was 9.8% and that of local cultivars was 17.8%. But the infected fruits rate of anthracnose in field were similar as 3.3% in commercial (F1 hybrid) and 3.1% in local (Purebred) cultivars. In yield characteristics, average yield of commercial cultivars was 2.89 t $ha^{-1}$ and that of local cultivars was 2.22 t $ha^{-1}$. For organic pepper farmers it is more favourable to cultivation purebred cultivars because they can save to the same quality plant next year's crop. In this study among the local purebred cultivars, two cultivars are promising that their yield near to 3 t $ha^{-1}$ and have disease field resistance.

The purpose of this article is analyzing the impacts of climate change on red pepper yield in Korea, with employing a panel data regression model. Our results show that there is a negative impacts of high temperature and precipitation amount on red pepper yields. Especially high temperature and rainfall in July cause serious damage to red pepper yield. According to the reduction schedule on greenhouse gas emission(RCP 8.5 scenario.), red pepper yield would be 25.4% lower than it is, for reasons of high temperature and rainfall damages by the end of 21st century.

A field experiment was conducted to investigate the effect of long-term (21-year) fertilizer and compost treatments on the yield of red pepper and chemical properties in top-dong, Suwon. Six treatments were chosen for this work: No fertilization (No fert.), NPK fertilizers (NPK), NPK and compost (NPK+Compost), NP and compost (NP+Compost), NK and compost (NK+Compost), PK and compost (PK+Compost). The yield of red pepper for 21 years indicated the significant differences among the No fertilization, the PK+Compost, and other treatments. The relative yield index was 13% and 59% respectively, for the No fertilization and the PK+Compost if the average yield of red pepper for the NPK regards $20,048kg\;ha^{-1}$ as the yield index with 100%. Soil organic matter at the compost applied treatments significantly increased compared with the No fert. and the NPK. The average increase rates of soil organic matter by applying the compost ranged from 0.69 to $0.73g\;kg^{-1}\;yr^{-1}$. Available phosphate content in soil appeared the significant increase all treatments excluding the No fert. It is estimated that the available phosphate in soil was increased by $7.0mg\;kg^{-1}\;yr^{-1}$ by applying compost and $14.2mg\;kg^{-1}\;yr^{-1}$ by applying P fertilizer. Application of K fertilizer or the compost alone, the NPK, the NP+Compost, continuously caused soil K depletion whereas K fertilization plus the compost maintained at a constant level of exchangeable K. The results indicated that the addition of compost to NPK fertilizer is recommended for the maximum stable yield for red pepper and enhancement of organic matter though it is also needed for adjusting of P and K fertilization.

고추 oleoresin의 적정 추출조건을 설정하기 위하여 추출에 영향을 미치는 몇 가지 인자들을 대상으로 oleoresin의 수율, capsanthin 및 capsaicin 함량의 변화를 조사하였다. Ethyl alcohol 용매로 추출한 oleoresin은 수율 및 capsanthin 함량이 높고, Ethylene dichloride 용매의 경우는 capsaicin 함량이 높게 나타났다. 혼합용매의 경우는 단일용매의 경우보다 수율은 증가하나 capsanthin 및 capsaicin 함량은 거의 변화가 없었다. 추출에 사용한 3가지 품종 중에서 진솔에서 추출한 oleoresin의 품질이 가장 우수하였다. 적정 추출온도 및 추출시간은 $20^{\circ}C$ 및 $3{\sim}5$시간이었다. 장기 저장한 고추일수록 고추분말의 입도가 클수록 추출되는 oleoresin의 품질은 저하되고, 함량도 적었다 고추의 과피에는 capsanthin이 씨에는 capsaicin이 가장 많았다. 고추분말과 추출용매의 적정혼합비는 $1\;:\;3{\sim}1\;:\;4(w/v)$였다.

The cultivation of once-over harvest pepper cultivars might be very valuable to Korean farmers who still depend on traditional hand-harvesting method. Thus, we conducted this experiment to obtain important information for enhancing the productivity of once-over harvest red pepper fruits by supplying several nutrient-controlling and growth-regulating chemicals, such as $KH_2PO_4$, $SiO_2$ and 2-chloroethylphosphonic acid (ethephon). Adequate fertilization was provided in each treatment plots. In this study, two once-over harvest pepper cultivars, Saengryeg No. 211 and 213 (SR 211 and SR 213), and one regular piecemeal harvest pepper cultivar, Kangryegdaetong (KRDT), were cultivated to evaluate the productivity of pepper fruit as affected by above chemicals. The distribution of macro- and micro-nutrients in pepper fruits among the cultivars were different in term of N, B, Cu, and Fe concentrations. In particular, the concentration of B in SR 213 was about 2 times higher than that in SR 211 and KRDT. However, overall red pepper productivity of SR 211 was markedly higher ($2.91{\sim}3.38Mg\;ha^{-1}$) than that ($1.68{\sim}2.37Mg\;ha^{-1}$) of SR 213. Also, the productivity of matured red pepper was significantly influenced by the treatments of $KH_{2}PO_{4}$, $SiO_2$ and ethephon. The yield indices for matured red pepper fruits were the highest with the treatment of $KH_2PO_4$ or $SiO_2$ with ethephon, which were 113~116% for SR 211 and 147~150% for SR 213. Thus, the applications of $KH_2PO_4$ or $SiO_2$ with ethephon would be suggested to enhance the productivity of matured red pepper fruit.

본 연구는 고추씨 분말이 닭다리살 재구성 육포의 이화학적 및 관능적 특성에 미치는 영향을 규명하고자 조사하였다. 고추씨 분말의 함량을 각각 0%(control), 1%, 2%, 3%를 첨가하여 닭다리살 재구성 육포를 제조하였으며, 실험 결과는 다음과 같다. 고추씨 분말을 첨가한 닭다리살 재구성 육포의 수분 함량이 대조구보다 유의적으로 높게 나타났으며 (P<0.05), 단백질 함량은 고추씨 분말을 첨가할수록 줄어드는 경향을 나타내었다. 가열 전후 pH는 고추씨 분말 첨가량이 증가할수록 감소하는 경향을 보였다. 가열 전후 명도, 적색도와 황색도는 고추씨 분말이 증가함에 따라 증가하는 경향을 보였다. 보수력, 건조수율은 고추씨 분말을 첨가할수록 증가하는 경향을 보였으나, 전단력은 고추씨 분말을 첨가할수록 감소하는 경향을 보였다. 관능평가에서 고추씨 분말을 3% 첨가한 닭다리살 재구성 육포의 색도, 풍미, 연도, 다즙성과 전체적인 기호도가 가장 우수한 평가를 받았다. 이상의 연구 결과를 종합하면 3% 고추씨 분말을 첨가한 닭다리살 재구성 육포가 조직감과 관능적 특성을 증진시킨다고 판단된다.

In this study, growth of pepper seedlings was tested by treating organic materials in a plastic green house in Ssangok-ri Dogok-myeon, Hwasun-gun, Jeollanam Province from February 3, 2010 to April 19, 2010. The raised seedlings were planted to the organic planting area with an interval of $70cm{\times}55cm$ on April 20 in Deogam-ri Gogeum-myeon Wando-gun and red peppers were harvested at 7 times from July 22 to September 29. Before planting, the plant length of the overgrowth of seedlings was reduced by 26.8% using plant powder treatment as compared to the control group. The red pepper yield was 27% higher than in the control group when 20g of bone ash powder and 20g of plant powder were mixed. The yield tended to increase in other treatments compared to the control group.

Nowadays, sustainable and environment-friendly agriculture has become an important issue all around the world, and repeated applications of mineral and/or organic fertilizer will probably affect mineral nutrient dynamics in soil in the long term but only a limited number of observations are available. This study was carried out to investigate whether there is any influence of different fertilizer management for red pepper (Capsicum annuum L.) cultivation on soil physicochemical properties, leaf mineral content, yield and fruit quality in the aspect of long-term practice in open field condition. NPK, NPK+compost, compost only, and unfertilized control plot were included in the treatments. The application of chemical fertilizer and/or compost repeated annually for 17 years from 1994 to 2011. Soil organic matter content was higher in compost treatments than in no-manure treatments. Available phosphate and the yield of red pepper were highest in NPK+compost treatment followed by NPK (chemical fertilizer), compost, and control. The results indicate that in the long term, nitrogen supply is still needed for increasing red pepper yield, but reduction in the use of chemical fertilizer could be also possible with the proper application of compost.
