Abstract: To investigate the effects of applying different types of organic fertilizers on the yield and quality of flue-cured tobacco under reduced chemical fertilizer conditions, based on the principle of “equivalent nitrogen replacement”, a treatment group without organic fertilizer was established as the control(CK), and treatment groups were set up by replacing 20%(T1, K1), 40%(T2, K2) and 60%(T3, K3) of the tobacco-specific compound fertilizer with sesame cake fertilizer(T) and rapeseed cake fertilizer(K), respectively. The experiment was conducted in Zunyi City, Guizhou Province. The results revealed that treatment T2 achieved the highest comprehensive score of tobacco yield and quality, indicating the optimal overall performance, followed by T1 and K2. Key agronomic traits including middle leaf length and middle leaf width under T2 were significantly superior to those of other treatments, with increments of 16.31% and 13.73% relative to the control(CK), respectively. Treatment T2 exhibited prominent economic performance, with both yield and output value being the highest, increasing by 64.65% and 94.13%, respectively, compared with CK. The reducing sugar content of K2 reached 30.06%, significantly higher than that of the other treatments except K1; nevertheless, T2 possessed superior coordination of chemical components with a comprehensive chemical quality score of 88.39, while K2 ranked second in overall chemical performance. T2 obtained an appearance quality score of 93.17, which was 38.71% higher than that of CK. In terms of sensory quality, T2 performed best in after taste and aroma quantity and attained the highest comprehensive sensory score, with K2 as the secondary performer. In conclusion, reducing the application of chemical fertilizer by 40% and combining it with sesame cake fertilizer (T2) could effectively promote the growth of Yunyan 87, increase its yield and overall quality.

Key words: tobacco, sesame cake fertilizer, rapeseed cake fertilizer, reduction of fertilizer use, fuzzy comprehensive evaluation, yield and quality
