<\/p>

The experiment was carried out at Alrensiya village in Tatous\ngovernorate in the Syrian coast during the agricultural season 2018, and based\non a randomized complete block design with three replicates. The aim of this\nstudy was to determine the response of Burley21<\/sub><\/em> tobacco to\nwater stress and nitrogen fertilizer additives. Both growing plants under full\nirrigation and water stress (50% of field capacity) were subjected to four\nnitrogen fertilizer additives (25, 50, 75 and 100) kg\/ha. So, the plant height,\nplant leaf area, leaf area index (LAI), photosynthesis rate and crop growth\nrate, chlorophyll and carotenoids contents, fresh and dry leaves yield and leaf\nthickness were studied. The nitrogen fertilization increased most of the\nstudied traits and indicators, both under irrigation conditions with full water\nrequirements and under water stress conditions. This positive effect was also proportional\nto the amount of fertilizers used. However, water stress, led to decreases in\nmost of the studied traits as compared to nitrogen fertilization treatments\nunder the full irrigation conditions. In addition, the nitrogen treatment\nimproved the growth and productivity indicators under water stress, and this\npositive effect was also proportional to the amount of fertilizers. The best\nresults were obtained at nitrogen fertilization of 100 kg\/h, either under\nirrigation conditions with full water requirements or under water stress\ncompared to other fertilization treatments<\/p>\n\n\n\n
