Abstract

The experiment was implemented at the Stakhris Agricultural Research Station in Latakia during the two successive seasons of Agricultural 2021/2022, according to a split-randomized block design, with three replicates for each treatment. The research aimed to study the effect of irrigation method and spraying with amino acids on the growth and productivity of tobacco plants, the Virginia tobacco variety (Nicotiana tabacum var. Virginie vk51), where the morphological and physiological characteristics were studied (plant height (cm) and total leaf surface area (m2/plant), and the content of air-dried tobacco leaves of biochemical compounds (total protein, soluble sugars, and nicotine (%)). Using the drip irrigation method with the third level of amino acids (I1A2) gave the best results, as it was significantly superior to the rest of the treatments, as the plant height value in this treatment reached (226 cm), which was reflected positively on the total leaf surface area of ​​the plant (3.52 m²). /plant), and the qualitative characteristics of dry tobacco leaf improved, as the percentage of total protein and nicotine decreased and the percentage of total soluble sugars increased. Based on the above, it can be suggested to use the drip irrigation method with the third level of amino acids, given their significant role in stimulating growth in the Virginia variety and improving the quality of the resulting tobacco.
