Abstract
This study was carried out to investigate the effects of cultivars and to establish the hydroponic cultivation method of spinach (Spinacia oleracea L.) f3r autumn season. Considering the rate of germination, plant height is 25 cm 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 20 cm was thought by suitable cultivars to domestic. Plant height relationship difference that follow to planting distances decreased according as planting distances growth than $12{\times}11$ cm to $12{\times}15$ cm. In the meantime, the increase of leaf area and fresh weight was increasing transplanting distance. The yield per ha of 14,890 kg in the $12{\times}11$ cm was $67{\%}$ increased than that in the $12{\times}9$ cm. Therefore, $12{\times}11$ cm spacing is considered optimum planting distance for spinach hydroponic cultivation in autumn season.
