Abstract: In order to know the optimum ratio of organic to inorganic fertilizers, the experiment was conducted to study the effects of different ratio of organic to inorganic fertilizers on yield and quality of flue-cured tobacco (Nicotiana tabacum L.) Yunyan 97 including agricultural characters,internal chemical compositions,sensory evaluation and economic benefit. The result showed that,compared with the control,after applying different ratio organic fertilizers,the content of total sugar and reductive sugar were increased,the content of total nitrogen and nicotine were reduced in some degree,the equal distributions of chemical compositions,the quality and quantity of aroma were improved, and the pungent odor was decreased in the treatments. When the ratio of organic to inorganic fertilizer was 25% to 75% applied,compared with the control,5 percentage point of the first class tobacco leaf was increased and 483.40 Yuan per 667 m2 was increased. Based on the comprehensive input and output efficiency of fertilizers,the 25% to 75% ratio of organic to inorganic fertilizer was recommended for Yunyan 97 planted in the rice field in Xingyi area.

Key words: flue-cured tobacco (Nicotiana tabacum L.), organic fertilizer, inorganic fertilizer, yield, quality
