Abstract
This experiment was carried out to define the effects of application amounts of the chemical fertilizers on plant growth and yield of the ginger. The results obtained are summarized as follows. Plant height of the ginger was 45.3 cm at lower level of fertilizer, 52.6 cm at recommended level, and 49.4 cm at higher level. Leaf area, stem number, and stem diameter were more significantly increased at higher level of fertilization compared to recommended rate. Dry weight of shoots and rhizomes were significantly increased with the increase of fertilization level. Stem number, stem diameter, leaf area, dry weight of shoots, and fresh weight of rhizomes were positively correlated with the amounts of fertilizer applied. Yield of rhizomes were 1, 653 kg at lower level of fertilizer, 2,248 kg at recommended level and 2,428 kg at higher level, respectively. Ginger yield showed 7.4% higher at higher level of fertilization compared to recommended rate.
본 시험은 시비량의 차이가 생강의 생육 및 수량에 미치는 영향을 구명하기 위하여 수행한 시험 결과를 요약하면 다음과 같다. 1. 초장은 감량구에서 45.3cm, 표준구에서 52.6cm 증량구에서 49.4cm로 표준구가 가장 크게 나타났다. 2. 엽면적과 경수, 경직경은 증량구가 표준구에 비하여 높게 나타났으며, 지상부와 근경의 건물중도 증량구에서 가장 높게 나타났다. 3. 경수, 경직경, 엽면적, 지상부 건물중, 근경의 생체중 등이 비료 수준과의 관계에서 감량구와 표준구간, 감량구와 증량구간에 유의성이 인정되었다. 4. 수량은 감량구에서 1653kg/10a, 표준구에서 2248kg/10a, 증량구에서 2428kg/10a로 증량구가 표준구에 비하여 7.4%의 증수 효과를 나타냈다.
