摘要：The temperature and precipitation have precious role in agricultural production which are varied during year and overtime. Using the historical data of yield, temperature, and precipitation in three adjacent agricultural districts of Georgia, this study attempts to assess the impacts of temperature and precipitation on mean yield of peanut production. Study finds that for all levels of temperature would have positive impact on peanut yield. The precipitation would produce the positive impact on yield up to certain limit but excessive precipitation would have negative effect on peanut yield.
