In order to clear the effect of excess soil moisture in ripening stage on grain quality of wheat and barley, pot-experiments were carried out from 1957 to 1960. The results were summarized as follows: 1000-grain-weight of kernel raised from the soil with air porosity below about 20 volume-percent of soil was significantly inferior to one from the control plot with larger air porosity. The lowering in production in the plot holding higher soil moisture was due to smaller air capacity, higher acidity and lower redox-potential of soil. In consequence, the plant grew poorly and declined in respiration and water absorption activities. The excess soil moisture in the first half of ripening stage was mose injurious than that in the second half on plant growing. High temperature encouraged excess soil moisture injury to plant ripening. The conclusion above-mentioned was supported by surveying those points in some practical wheat fields around Chikugo Area.
