...Research on the quality of raw tobacco from the 2024 crop in Cao Bang province revealed a relatively high stem-to-leaf ratio in cured tobacco: 36.6% in leaves from the middle stalk section (C section) and 36.8% in leaves from the upper stalk section (B section), showing increases of 1.9% and 3.4% compared to the 2023 crop. Consequently, the leaf fragment yield during stem separation decreased. Nicotine content in the c and B section leaves was 1.36% and 2.06%, respectively-lower than in the 2023 crop, likely due to both weather conditions and the use of local varieties with naturally low nicotine levels. High chlorine levels in the leaves were attributed to KCL fertilizer application or residual chlorine from the preceding rice crop. Overall, the quality of raw tobacco in the 2024 crop fell short of expectations. To address these challenges, technical solutions are recommended, including minimizing low-nicotine local varieties and increasing the use of high-quality varieties like GL7, GL9, and D65, using specialized tobacco fertilizers instead of KCL, applying fertilizers appropriately, and improving crop management practices such as topping and suckering.
