Abstract
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 293cm. 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 $253mg{\cdot}kg^{-1}$ compared with control of $331mg{\cdot}kg^{-1}$, 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 $4,190kg{\cdot}10a^{-1}$ compared to control of $3,643kg{\cdot}10a^{-1}$, and OLF-1.3X and OLF-0.7X treatments showed increase by 10% and 6%, respectively.
본 연구는 개발된 유기액비의 시용량이 고추 생육 및 과실 품질에 미치는 영향을 구명코자 실시하였다. 개발된 유기액비의 조성은 계분 : 쌀겨 : 대두박(2:1:1, w/w)이며, 시험 처리는 화학비료 시비구인 대조구와, 유기액비의 표준 시비량 처리구인 OLF-1.0X 처리구, OLF-1.0X의 70%수준인 OLF-0.7X 처리구, OLF-1.0X의 130% 수준인 OLF-1.3X 처리구 등 4 처리를 하였다. 초장은 OLF-1.0X 처리구에서 대조구 293cm에 비하여 23cm 감소하였으나 과수는 유의하게 증가하였다. OLF-1.0X 처리구에서 홍고추의 총 캡사이신 함량은 $253mg{\cdot}kg^{-1}$으로 대조구 $331mg{\cdot}kg^{-1}$으로 보다 23.6% 감소하였으나, 유리당 함량은 19.5% 증가하였다. OLF-1.3X 처리구의 총 캡사이신 함량과 가용성 고형물 함량은 다른 처리들과 유의성을 나타내었다. OLF-1.0X 처리구의 홍고추 수량은 $3,490kg{\cdot}10a^{-1}$으로 대조구 $3,168kg{\cdot}10a^{-1}$보다 10% 증가하였으며, 총수량은 15% 증가하였다. 따라서, 고추 유기액비 관비재배시 적정시용량은 OLF-1.0X로 밝혀졌다.
