In Oita prefecture, growth and yield of standard cultivar shave been investigated at fourteen places for paddy rice and eight for wheat and barley through recommanded cultivar selection project. And the data for air temperature of each place have been accumulated using the automatic weather recording system since 1988. The main purpose of this research is to clear the relationship between the air temperature, and the growth or yield of each cultivar. Furthermore, in expeirimental farm (Usa city) we estimate the growth stages, degree of lodging and number of unhulled rices for rice cultivars. As for wheat and barley, we estimate the heading date on the basis of length of young panicle, young culm, and so on. At the same time, we aim at making efficient use of estimateddata.
