Abstract

Abstract: In order to explore the optimal nitrogen application rate for cigar tobacco cultivation in Shandong tobacco-growing regions, using the cigar variety QX103 as experimental material, and different nitrogen application levels (0, 75, 120, 165, 210 kg/hm²) were established to analyze their effects on the agronomic traits, nutrient accumulation, photosynthetic characteristics, appearance quality, physical properties, chemical composition, and economic performance of cigar tobacco. The results showed that with increasing nitrogen application, leaf width and leaf area initially increased and then decreased. Conversely, leaf thickness, palisade tissue thickness, and tissue compactness exhibited an increasing trend. Photosynthetic capacity, as well as the score of maturity, oil content, body, and color uniformity of wrapper leaves, initially increased and then decreased with increasing nitrogen application, and the optimal performance was observed at the nitrogen application rate of 120 kg/hm². Under this fertilization level, the physical characteristics and chemical composition of the wrapper leaves were well-balanced and met the quality standards for premium wrappers. Furthermore, the total yield, wrapper yield, wrapper output rate, and output value all reached their maximum levels at this application rate. It could be concluded that an appropriate increase in nitrogen application could promote the growth, development, and photosynthetic efficiency of cigar tobacco, enhance the appearance quality, improve the physical properties of wrapper leaves, and optimize their chemical composition. Taking into comprehensive consideration both the yield and quality of wrapper leaves, the recommended nitrogen application rate for cigar tobacco cultivation in Shandong tobacco-growing regions was 120 kg/hm².
