The climatic conditions during the growth period in 1994 and 1995 were different from those in normal years. The longer sunshine duration, higher radiation intensity and higher air temperature were considered the important factors responsible for the higher yield in the present experiment. The yield of soybeans in the present experiment was higher and reached of 397-661g m-2 more than the average yield of 302g m-2 for Ehime Prefectural Experimental Station. The results obtained in the present experiment indicate that soybean plants have capacity to produce higher grain yield under the climatic conditions like that in 1994 and 1995. The climatic conditions during the ripening stage were a little different between two years. Longer sunshine duration, higher radiation intensity and higher ai temperature during the ripening stage in 1994 might have contribution to higher LAI and higher NAR and hence higher CGR. The higher CGR during the ripening staged in 1994 as consider to produce higher seed weight and hence higher seed yield. © 1997, The Society of Agricultural Meteorology of Japan.
