Agrobiological characteristics, yield, and resource-use indicators of selected Burley tobacco cultivars in Dak Lak Province

This study evaluated the agrobiological characteristics, major disease incidence, yield, and resource-use indicators of six imported Burley tobacco cultivars: B1451, L1416, L1509, L1533, L1596, and L1608, with KY14 as the control during the 2025–2026 season in Ea Bung, Dak Lak Province. The experiment used a randomized complete block design with three replications. Actual cured-leaf yield ranged from 3.20 to 3.63 t/ha. L1533 produced 3.63 t/ha, comparable with KY14 at 3.48 t/ha, while maintaining a 104-day growth period, 23.7 harvested leaves per plant, and a fresh-to-dry ratio of 8.17. L1608 matured in 98 days and yielded 3.38 t/ha, indicating potential for shorter production cycles and reduced labor and curing-barn requirements.
