【 摘 要 】

We examined the soil water content and plant height of wheat cv. Norin 61 in 26 fields in Inashiki City, Chikusei City and Sakuragawa City in the southern part of Ibaraki Prefecture in Japan. A significant negative correlation was found in a 1.8 ha paddy field in Inashiki City in 2007. This negative correlation was also found in 6 out of 7 fields in other cities in 2007. The negative correlations were found in 15 fields, however, a positive correlation was found only in one out of 19 fields in 2008. The relationship between soil nutrient contents and the plant height in these fields was not clear. These results suggested that excess soil moisture limited wheat growth in many fields in Ibaraki Prefecture.
