In trials with rice Sasanishiki, the uptake of N was measured during various parts of the growth period for plants grown in 4 different regions of Yamagata Prefecture. Data were presented for the average yield of rice in the whole of Yamagata and in these regions for the period 1965-88. Differences were found in the patterns of N uptake and in the yields in the different regions.
