Methods for optimizing Japanese radish cv. Natsutukasa cultivation using single seed sowing were assessed for individual plants by examining variations in seed size, seed sowing depth, type of tape seeder machine, and the effect of urea fertilizer application. The highest rates of germination were found in seeds, which had seed diameters exceeding approximately 2 mm. Seed sowing depth also affected germination in radish plants and the occurrence of vacant hills increased with sowing depths below 3 cm. Application of two grains of urea fertilizer at distances of 2 cm from each seed point increased root thickening during the latter growth stage. We think that this combined method for single seed sowing cultivation is of practical use because the occurrence of vacant hills is similar to those of ordinary thinning cultivation and root thickening growth is intensified.
