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.

The experiment was carried out to examine the effect of pinching time on growth and marketable yield of okra in rain shielding vinyl houses. Okra (Abelmoschus esculentus L., 'Green sod') seedling was transplanted in May, 2013. Pinching times of okra were in each 30th, 45th, 60th day after transplanting of okra. Shoot branch and top fresh weight were significantly different between each pinching times. Top fresh weight were highest at 60th day pinching time after transplanting investigated, and were lowest at 30th day pinching time after transplanting. There was no significant difference in plant height and stem length among pinching times. According to pinching times, marketable yield and number of okra fruits were varied. Marketable yields were highest at 60th day after transplanting, whereas were lowest at 30th day after transplanting. Mineral concentrations of okra fruits were not significantly different among pinching times. Therefore pinching times 60th day after transplanting was effective to increase yield of okra fruit in rain shielding vinyl houses.
