Possibility of Producing Good Eating Quality Rice with Special Reference to Water Quality in Noto

Abstract

This paper discusses possibilities of producing good eating quality rice in Noto. Good water quality, large difference between day and night temperatures and lower nitrogen level during heading stage are considered to be important factors for producing good eating quality rice. Irrigation water quality was compared between Noto and Niigata. The sunshine duration and difference between day and night temperatures during the grain-filling phase at Noto were compared at Tohkamachi and Yuzawa which are about 10km from Uonuma where the best quality rice is produced in Japan. Based on my study, those factors are fulfilled in Noto. Therefore, I think there is high possibility for Noto to produce good eating quality rice.
