抄録

The superb weather during growing period produced a high yield and a high quality of wheat and two-rowed barley in northern Kyushu in 1999. The crop situation index and the average yield in Fukuoka Prefecture were 132 and 447 g/m2 for wheat and 118 and 398 g/m2 for two-rowed barley, respectively, the second highest since 1945. Furthermore, the inspection grade became higher because of the increase of well-developed grains. Wheat's high yield was caused by an increase in the number of ears and 1, 000-grain weight in response to a low precipitation during the growing period and sufficient sunshine hours during the ripening period. Two-rowed barley's high yield was caused by a increase in the number of ears and well-developed grains in response to sufficient sunshine hours during the ripening period. The yield and apparent quality of wheat were improved by a recduction of the first top dressing of nitrogen at the tillering stage and a thin sowing in early sowing culture in abnormally warm and dry weather. In terms of cultivar, the good yield was caused by a wide diffusion of the high yielding and quality wheat cultivar Chikugoizumi.
