Abstract<\/strong><\/p>\n\n\n\n

The experiment was carried out at the Agricultural Research Station, Setkhiris,\nLattakia, during the agricultural season 2018, according to the randomized\ncomplete block design (RCBD) with three replicates per treatment. The research\naimed to study the effect of drip irrigation and potassium fertilization that\nwas added to irrigation water or directly to soil on\ntobacco (Nicotiana tabacum var. Virginie vk51<\/em>), and on some physical\nsoil properties (bulk density (g\/cm3<\/sup>) and total porosity (%)), and\nmorphological and physiological characteristics (the number of leaves per plant,\nplant leaf area (m2<\/sup>)), and yield of fresh and dry leaves (kg\/1000 m2<\/sup>),\nbesides the content of dry tobacco leaf with biochemical compounds (the total\nprotein and the soluble sugars, nicotine (%)) and some mineral oxides (K2<\/sub>O)).\nThe drip irrigation method with potassium fertilization reduced the bulk soil\ndensity, that was positively reflected on the increase of the total porosity\nduring the agricultural season, and increased number of leaves per plant and\nplant leaf area, and giving the highest fresh yield of leaves (2120.7 kg\/1000 m2<\/sup>)\nand dry yield of leaves (441.31 kg\/m2<\/sup>), especially when the whole\npotassium fertilizer was added to the irrigation water, as well as improving\nthe quality of dry tobacco, where the total protein and nicotine content (%)\ndecreased, and the percentage (%) of total soluble sugars increased. According\nto the results, it could be proposed the use the drip irrigation method with\npotassium fertilization added to irrigation water, considering to its significant\nrole in stimulating the growth of the Virginie<\/em> variety and in improving\nthe quality of tobacco produced. <\/p>\n\n\n\n
