This study was carried out to evaluate the effects of applying levels of organic liquid fertilizer (OLF) on growth and fruit quality of hot pepper. The OLF was made with compositions of chicken dung : rice bran : soybean meal (2:1:1). Hot pepper was applied with 5 treatments; control (chemical fertilize), OLF-1.0X (standard applying levels), OLF-0.7X (70% of standard applying level), and OLF-1.3X (130% of standard applying level). The plant height was reduced at 23cm in the OLF-1.0X treatment compared to control of 293㎝. The number of hot pepper fruits was significantly increased. The content of capsaicin in the ripened pepper decreased by 23.6% in the OLF-1.0X treatment with 253㎎ㆍ㎏⁻¹ compared with control of 331 ㎎ㆍ㎏⁻¹, but the content of free sugar increased by 19.5%. The content of capsaicin and soluble solid content in OLF-1.3X treatment were significant different with other treatments. The yield of red pepper in OLF-1.0X treatments increased by 15% with 4,190㎏ㆍ10a⁻¹ compared to control of 3,643㎏ㆍ10a⁻¹, and OLF-1.3X and OLF-0.7X treatments showed increase by 10% and 6%, respectively.
The present study was carried out to evaluate the effects of organic liquid fertilizer (OLFs) fertigation on the growth and fruit quality of hot pepper (Capsicum annuum L.) cv. ‘Nokkwang (Seminis Korea)’. Treatments were given with control (chemical feritilzer), OLF Ⅰ(fowl dropping : fish meal : soybean meal, 2:1:1), OLF Ⅱ(fowl dropping : bone meal : soybean meal, 2:1:1), OLF Ⅲ(fowl dropping : bone
meal, 1:1), and OLF Ⅳ(fowl dropping : rice bran : soybean meal, 2:1:1). The composition ratio of OLF based on weight to weight. The pH and EC of OLFs according to different material and compositions ranged from 6.5 to 6.8, and from 2.91 to 3.69dS · m-1, respectively. The C/N ratio was the highest as 5.75 in OLF Ⅳ, and there was no difference among the treatments in C/N ratio of the exception of OLF Ⅳ. In OLF Ⅳ total fruit weight was the highest as 1,558g per plant and total fruit number increased as 23.7% compared to control. The content of capsaicin in the ripened pepper increased with OLF Ⅰ and Ⅱ treatments, and decreased with OLF Ⅲ and Ⅳ treatments compared to control of 662mg ․ kg-1, but the soluble solid content was the highest with OLF Ⅳ treatment as 10.0°Brix.
황기(Astragalus membranaceus)를 첨가한 청국장의 품질 특성을 조사하였다. 수분함량은 발효가 진행됨에 따라 감소하였고 조단백은 약간 증가하였다. pH는 발효초기에 약간 감소한 후 증가하는 경향을 보였으며, 아미노태질소는 24시간까지는 황기 첨가구가 높았으나 이후에는 대조구가 높았다. 색도(명도, 적색도, 황색도)는 감소하였다. 발효온도 에서 ACE 저해도는 대조구 48시간 86.0%, 황기첨가구 24시간 95.3%로 가장 높은
본 연구는 검은비늘버섯(CBPM-6호)의 선도유지 효과를 알아보기 위해 포장재(Wrap, PE, PP, AE)및 저장온도(1, 3, 6)을 달리하여 18일간 조사한 결과는 다음과 같다. 저장기간 중 포장재별 중량 감모율은 랩포장시 1에서 18일 후 3.17%이었으나, AF필름에서는 1.08%의 낮은 중량 감모율을 나타내었다. 색도는 저장기간이 연장될수록 명도와 황색도는 약간 증가하는 반면 랩 포장에서는 감소하는 경향을 나타내었다. 버섯 저장 전
검은버섯분말 3, 5, 7%를 첨가하여 국수를 제조한 후 품질을 분석해 련 결과 최고점도와 최종점도 및 노화도는 무처리보다 버섯첨가구에서 모두 낮은 값을 나타내었으며 첨가량이 증가할수록 낮아지는 경향을 나타내었다. 버섯분말첨가량이 증가함에 따라 수분흡수율은 약간 증가하였다. 색도는 버섯분말의 첨가량이 증가함에 따라 분말, 반죽, 국수등 모든 처리구에서 명도는 낮아졌으며, 적색도와 황색도는 증가하는 것으로 나타났다. 버섯국수 조리후 중량과 부피는
진품콩에 작두콩의 종실을 첨가하여 맛과 영양이 우수한 요구르트를 제조하기 위하여 진품콩에 작두콩의 혼합 비율별로 두유를 착즙하고 유산발효 시킨 제품의 가공특성을 검토하였다. 원료콩의 단백질 함량은 진품콩이 38.0%로 작두콩 27.5f%보다 높았다. 유산발효 중 PH와 당도는 발효개시 후 4시간까지는 급격히 저하했다가 8시간 이후에는 완만하게 감소하였으며 유기산 함량과 유산균 수는 증가하였고, 20시간 발효시 진품콩 100%에 비하여 진품콩 95

This experiment was conducted to develop liquid fertilizer for leaf vegetable using the agricultural by products such as dry chicken dropping, bone meal, rice bran, soybean oil cake and fish meal. Combination of 50% dry chicken dropping, 30% bone meal and 20% rice bran among several combinations of by products was selected as materials for liquid fertilizer of head lettuce and cabbage. 50㎏ of materials with combination selected got mixed to 200ℓ of water, which kept under room temperature in greenhouse. EC and pH of fertilizer was stabilized after 35 days.
On the decrease of bad smell during fermentation, addition of materials such as bioceramics, woody vinegar and active charcoal was not effected. And on rapid fermentation, addition of microorganisms and sugar had a little effect, but decreased the content of inorganic nutrients. Fertigation of liquid fertilizer developed on cabbage by dropping made head weight increased by 0.9㎏ per plant and nitrate content decreased by 276ppm in comparison with chemical fertilizer which was 3.5㎏, and 2,426ppm, respectively. By use of organic liquid fertilizer developed in this experiment, yield of cabbage could be more obtained by 26% than in use of chemical fertilizer and income by 24%.
