Yield variability of crops in Japan

Auteur :
UCHIJIMA, Z.

Description :
Yield and climate data are analysed to obtain relationships between yield variability and weather variability. The analysis indicates that the influence of weather variability on crop yield is greater in regions with poor agroclimatic resources than in regions with good agroclimatic resources. The spectral analysis is made to study in more detail regional characteristics of yield fluctuations. It is reported that Japan can be classified into five districts from the stand point of characteristics of yield fluctuations.
