Abstract: 【Objective】The purpose of this experiment is to research the effects of application of different types of cake fertilizer combined with chemical fertilizer on the flavor quality of the flue-cured tobacco leaves. 【Mothod】The field experiment was done to investigat the contents of the petroleum extracts, chemical and aroma components of flue-cured tobacco leaves by applying different types of cake fertilizer combined with chemical fertilizer. 【Result】The contents of petroleum extracts in leaves were significantly increased in the four cake fertilizer treatments compared with chemical fertilizer treatment . The contents of aroma components in leaves were also increased in the four treatments. High quality leaves containing the suitable ratio of nicotine and reducing sugar could be obtained by the sesame cake treatment. The sensory evaluation indicated that the higher flavor quality of leaves could be obtained by the treatment. The leaves in cake fertilizer treatment had the characteristics of good aroma quantity, full aroma quality, small odor, suitable irritation, comfortable lingering smell, mild smoke and good combustibility. 【Conclusion】So the higher sensory smoking scores was gained in the cake fertilizer treatment. Consequently 50% of sesame cake N added with 50% of chemical fertilizer N is the optimum combination in tobacco-growing region of Henan Province.
