This study was carried out to investigate the effects of cultivars and to establish the hydroponic cultivation method of spinach (Spinacia oleracea L.) for autumn season. Considering the rate of germination, plant height is 25cm interior and exterior and leaf blade and petiole attitude is erect the best two cultivars Artlars, Dimple were selected among the 19 cultivars tested. Seed germination was more than 90% in both cultivars of Artlars, Dimple. Seed rate of germination drops more or less, but it was cultivar that Mahoroba cultivars is becoming in export standard production, and Premium, Platon cultivar which plant height of leaf blade and petiole attitude is erect is about 20cm was thought by suitable cultivars to domestic. Plant height relationship difference that follow to planting distances decreased according as planting distances growth than 1211cm to 1215cm. In the meantime, the increase of leaf area and fresh weight was increasing transplanting distance. The yield per ha of 14,890kg in the 1211cm was 67% increased than that in the 129cm. Therefore, 1211cm spacing is considered optimum planting distance for spinach hydroponic cultivation in autumn season.
