Abstract
In Kanto district we can find light volcanic ash soii scope with poor land, low temperature and dry climate. Especially, in such soil scope, freezing layer, which does not melt whole day, is made up under the condition that mean temperature is below than 2°C. On this land, wheat and barley are not so grown. In ease when the roots of wheat and barley cannot go through the freezing layer, the plant is tend to be injured from drgught and cold. As the characteristics of the varieties fit to the land, good growth in earley period is required. The root system of the wheat and barley which is planted later, can not go down under the ground, and so is likely to be damaged, Consequently, in selection of variety as well as in cultivation method, it is important to take care in the earley period of the plant.
