The Relation between the Yield of Barley and the Weather Factors. Part. II

[摘要] Studies of the Relations between teh Yield of Chief Crops and the Weather Factors in Japan. No.11.The equation for estimating the yield of barley from the weather factors which are closely correlated with the yield is obtained by the method reported in a previous number of this journal for each prefecture in Japan.The mean error of the estimated yield is larger than 10% in Miyagi, Osaka, Wakayam, kagawa, and Kagosima prefectures, and smaller than 5% in Gumma, Isikawa, Siga, and Tottori prefectures. (see fig. 1.). Its mean value for all the prefectures in Japan is 7.3%.The results of the present study will be very useful for forecasting the yield of barley.
