Relation between the Yield of Naked Barley and the Weather Factors, Part I

Studies on the Re_??_ations between the Yield of the Important Crops and the Weather Factors in Japan. No.7

Abstract

The coefficients of correlation between the yield of naked barley and the weather factors (Monthly mean temperature, monthly amount of rainfall and monthly total hours of sunshine) have been calculated by the method previously reported in this magazine, for each prefecture in Japan, each month during the cultivating time.
The correlation coefficients calculated are shown in tables 1, 2, 3.
From the correlation coefficients we see clearly that the weather at the early stage of growth and from flowering to ripening time has most important influence upon the yield of naked barley and it is favourable for the naked barley culture when the weather is rainless, sunny at the above each time.
