[ABSTRACT] This paper compares the applicability of the Crop Production Index CPI with conventional methods, taking into account the acquisition of the necessary data by remote sensing. The author has developed the CPI index as a remote sensing method for monitoring grain production in the early stages of crop growth in Japan and Asia. A photosynthesis based crop production index CPI takes into consideration the solar radiation, the effective air temperature, and NDVI as a factor representing vegetation biomass. The CPI index incorporates temperature influences such as the effect of temperature on photosynthesis by grain plant leaves, low-temperature effects of sterility, cool summer damage due to delayed growth, and high-temperature injury. These latter factors are significant at around the heading period of crops. The CPI index for rice was validated at ten monitoring sites in the central and northern half of Japan. This paper proves the ability of the CPI to predict poor crop production using rice yield statistics, contrasting it against conventional methods such as the cumulative Growing degree day GDD, integrated NDVI, and photosynthesis rate.
