Interrelationships between yields of Burley 21 variety and meteorological factors such as precipitation, duration of sunshine, and evaporation in Suweon, Chungju, Daegu, and Jeonju were investigated during the growing seasons from 1976 to 1985. Cultivation period from the 41st to the 60th day after transplanting which showed the highest transpiration by the tobacco plant was corresponding to relatively dry season in Korea from the middle of May to early of June. The meteorological factors during the middle stage of the tobacco growth, especially the 41st to the 80th day after transplanting, seemed to have higher correlation with tobacco yield, than any other periods. This result implied that the middle stage of the growth when tobacco plant consume more soil moisture by transpiration proved to be a important growth stage having a great influence upon tobacco productivity.
