Abstract: To clarify the effects of different types of organic bran fertilizers on the yield, quality and economic benefit of flue-cured tobacco in Qingyuan City, Guangdong Province, and to screen suitable high-quality organic fertilizer substitution schemes for this region, Yueyan 97 was used as the test variety, and five treatments were set: conventional commercial fertilizer (CK), sesame bran fertilizer (T1), peanut bran fertilizer (T2), rapeseed bran fertilizer (T3) and soybean bran fertilizer (T4). The agronomic traits, economic traits, chemical composition, sensory quality and appearance quality indicators of flue-cured tobacco were systematically determined, and the AHP-entropy weight TOPSIS model was constructed for multi-indicator comprehensive evaluation. The results showed that T1 performed best in plant height and leaf number at the mature stage; T2 had the highest yield of 2 966.19 kg/hm2, which was significantly increased by 9.98% compared with CK; T1 achieved the best economic benefit with an output value of 96 611.69 yuan/hm2, which was significantly increased by 20.90% compared with CK; the proportion of superior tobacco leaves in T1 was significantly increased by 20.23% compared with CK. In terms of chemical composition, T2 had a higher nicotine content, while T1 exhibited a higher sugar-nicotine ratio. Sensory evaluation indicated that sesame bran fertilizer performed outstandingly in improving the aroma quality and appearance quality of upper leaves as well as the aroma quality and aroma quantity of middle leaves of flue-cured tobacco. According to the comprehensive AHP-entropy weight TOPSIS evaluation results, the ranking of each treatment was T1>T2>T4>CK>T3. In conclusion, sesame bran fertilizer and peanut bran fertilizer could improve the yield, quality and sensory style of flue-cured tobacco in Qingyuan City, among which sesame bran fertilizer had the best comprehensive performance and could be recommended as the preferred organic fertilizer for substituting chemical fertilizer in this tobacco-growing area.
