[Objective] The aim was to explore the flue-cured tobacco variety and the cultivation technology suitable for popularization and cultivation in the tobacco area in west Anhui.[Method] The split plot design was applied and with the nitrogen application amount as main factor and variety as secondary factor,the main agronomic characters,economic characters and intrinsic chemical composition of 3 flue-cured tobacco varieties with different treatments were analyzed.[Result] The variety 9601 showed obvious premature trend and its field growth vigor was stronger than that of Yunyan 87 and Yunyan 85.The most suitable nitrogen level of the 3 varieties was 97.5 kg/hm2 under the local ecological condition.Among the 3 varieties,the comprehensive economic characters of the variety 9601 were prominent,which was better than that of the other two varieties and was suitable for popularization and cultivation in the tobacco area of west Anhui.Adding proper application amount of potassium fertilize was helpful for coordinating the intrinsic chemical composition of tobacco leaf.[Conclusion] The research provided the technological basis for the renewal of tobacco variety in the tobacco area of west Anhui.
