The Effect of Different Planting Densities on Yield, Yield Components and Some Quality Characteristics of Virginia (Sun-Cured) Tobacco in Manisa Province

This study was conducted in 2023 under Manisa / Karayenice ecological conditions. The aim of the study was to determine the yield and yield components and some chemical properties of sun-cured virginia tobacco variety with different planting densities. Three different planting densities (40x70 cm, 50x70 cm and 60x70 cm) were applied in the study which was carried out with 3 replications according to randomized blocks experimental design. Plant height (cm), number of leaves (per plant-1), leaf width (cm), leaf length (cm), yield (kg ha-1), total alkaloid (nicotine) (%) and total reducing sugar (%) were analyzed. As a result of the results obtained from the experiment; plant height 184-190 cm; yield 409-434 kg da-1; total alkaloid (nicotine) content 1.738-2.360%; total reducing sugar content 1.94-3.92%. It was concluded that it is suitable for sun-cured virginia tobacco cultivation in the region; when yield and yield components are considered, 50x70 cm planting density and when chemical properties are prioritized, 60x70 cm planting density can be recommended.
