This experiment was carried out to examine the effects of time of water supply on the growth of seedlings and their yield in eggplant, cv.'Hayabusa'.<BR>1) The growth of seedlings was affected by time of water supply. Especially noon watering induced vigorous growth with a higher<I>S/R</I>value at transplanting time, while morning watering arrested the growth accompanying by a lower<I>S/R</I>value.<BR>2) Seedlings received morning watering during the period of raising seedling grew faster and established a deeper and wider root system consisting in a lot of thick roots over 1 mm in diameter after transplanting, resulted in the highest yield compared with those grew under noon or evening watering.<BR>3) The more number of thick roots over 1 mm in diameter had the plant, the higher its yield. Then there was found a close correlation between the number of thick roots and yield.<BR>4) Seedlings which showed lower<I>S/R</I>value with larger leaf area at transplanting time produced higher yield in vinylhouse. There was a correlation between this value and yield.
