Abstract

The experiment was carried out to examine the effect of planting date on the growth and marketable yield on rain shielding vinyl house in Busan area. Okra cultivars were 'Jukokra', 'Greensod', 'Marumichang', 'Betafive' and 'Akamarumichang'. Planting date were June and July. Plant height, stem length and leaf width were significantly different between various cultivars. Plant height and stem length were best at 'Akamarumichang' among all cultivars tested and the 'Betafive' cultivars showed the lowest plant growth of June treatment. There was no significant difference in planting of July treatment. Marketable yield of okra fruit was affected by planting date. In case of June planting date, 'Betafive' cultivars produced the highest marketable yield (4,286 kg/10a) in green fruit. Marketable yield of green okra fruit was increased at 'Betafive' and 'Greensod' cultivars, whereas 'Marumichang' cultivars was lowerd. Therefore, the optimum planting date was considered June planting in rain shielding culture of okra in Busan area.

본 연구는 부산지역의 비가림하우스에서 오크라의 정식시기와 수량에 미치는 영향을 조사하기 위하여 수행되었다. 오크라의 품종은 '적오크라', '그린소드', '마루미짱', '베타화이브', '아카마루미짱' 등 5개 품종을 이용하여 6월과 7월에 정식을 실시하였다. 오크라의 초장과 절간장은 품종간에 유의한 차이가 있었다. 6월에 정식한 처리구에서 오크라의 초장과 절간장은 '아카마루미짱' 품종에서 가장 길었으며, '베타화이브' 품종에서 가장 짧았다. 반면, 7월에 정식한 처리구에서는 품종 간에 생육의 차이가 없었다. 오크라 과실의 수량은 정식시기에 따라 유의한 차이가 있었다. 오크라의 녹색 과실의 수량은 6월 정식에서 '베타화이브' 품종이 4,286kg/10a으로 가장 많았다. 또한, 녹색 오크라 품종은 6월 정식의 경우 '그린소드' 품종과 '베타화이브' 품종에서 수량성이 좋았으며, '마루미짱' 품종은 수량성이 낮았다. 따라서, 부산지역 비가림재배에서 정식시기는 6월 초순에 정식하는 것이 적합하였다.
