Abstract

This study was conducted to investigate the seedling qualities and growth of paprika according to various irrigation points (IPs) (30, 40, 50, 60 or 70%) compared to the weight of rockwool cube with 100% water content for raising seedlings of paprika. Growth degree of paprika seedlings was positively correlate with various irrigation points. In particular, paprika seedlings with IP 30-40% and IP 50-70% treatments were significantly higher than those with other treatments. Leaf area of seedlings was 50-100% wider in those with IP 50% and IP 40% treatments than those with other treatments, therefore dry weight was heavier in IP 30-60% treatments. The dry weight of more than IP 50% treatments had no significant differences. Leaf area (Y1) had a significant relation with the irrigation point (x) as Y1 = 48.311x + 133.7 (R2 = 0.9116**). Also dry weight (Y2) of the seedlings showed a linear regression equation as Y2 = 0.1584x + 0.8616 (R2 = 0.8853*). Considering the leaf area and the dry weight of irrigation points for rising seedlings of paprika in this study, the optimum range of the irrigation points in the water contents of rockwool cube is IP 50%.

본 시험은 저면관수 방식의 파프리카 육묘 시 암면큐브에 대한 다양한 급액시점 (IP 30%, 40% 50%, 60% 및 70%)에 따른 파프리카 묘의 소질을 조사하였다. 급액시점에 따른 파프리카 묘의 생육량은 급액시점과 정의상관을 나타내었다. 특히 IP 30~40% 처리구와 IP 50~70% 처리구들 간 뚜렷한 차이를 나타내었다. 엽면적은 50% 이상의 처리구에서 40%이하의 처리구에 비해 50~100%정도 더 넓었고, 건물중도 30%~ 60% 정도 더 무거웠다. IP 50% 이상 처리구에서 건물 중의 유의한 차이는 없었다. 급액시점(x)은 파프리카 묘의 엽면적(Y1)과 Y1=48.311x+133.7(R2 = 0.9116**), 건물중(Y2)과는 Y2=0.1584x+0.8616(R2 = 0.8853*)의 선형회귀관계를 나타내었다. 따라서 본 연구 조건에서 파프리카 육묘 시 처리 간 엽면적과 건물생산량을 고려하였을 때 수분함량 100%인 암면큐브 무게의 50%에 급액하는 것이 적합하고 경제적일 것으로 생각된다.
