style="color:black"><span style="color:#0d0d0d">Drought stress is one of the most important abiotic stresses that limits plant growth and yield, especially in arid and semi-arid regions, by disrupting water and nutrient uptake and physiological processes. In order to investigate the role of organic fertilizers in improving spinach yield under drought stress conditions, a factorial experiment was conducted in a completely randomized design (</span><span style="background:white"><span style="color:#0d0d0d">CRD</span></span><span style="color:#0d0d0d">) with three replications in greenhouse conditions. The treatments included 13 individual levels and mixtures of liquid fertilizers Zargreen, molasses and vinasse with ratios of 100-0-0(Z1), 75-25-0(Z2), 75-0-25(Z3), 50-25-25(Z4), 0-100-0(M5), 25-75-0(M6), 0-75-25(M7), 25-50-25(M8), 0-0-100(V9), 25-0-75(V10), 0-25-75(V11), 25-25-50(V12) and 0-0-0(C13) in three-kilogram pots at a rate of 0.14 ml and two moisture levels of 100% field capacity and 75% field capacity. The results of the experiment showed that drought stress caused a decrease in the fresh and dry weight of shoots and roots, height, chlorophyll a and chlorophyll b, and an increase in the amount of soluble carbohydrate</span><span style="color:#0d0d0d">s</span><span style="color:#0d0d0d">, while the use of organic fertilizers improved the conditions compared to the control. The best treatment (Z1) caused a 34% increase in height, 53% in fresh weight, 30% in chlorophyll a and 35% in chlorophyll b, and a 35% decrease in soluble carbohydrate</span><span style="color:#0d0d0d">s</span><span style="color:#0d0d0d"> and 5% in water consumption. In general, the use of organic fertilizers was able to reduce some of the negative effects of drought stress and improve spinach yield.</span></span></span></span></span><br> &nbsp; اسید آمینه, زرگرین, کلروفیل, ملاس, ویناس Amino acids, chlorophyll, molasses, vinasse, zargreen. 277 300 http://journal-irshs.ir/browse.php?a_code=A-10-1027-1&slc_lang=fa&sid=1 Edris Gavili ادریس گویلی Edris_Gavili@Yahoo.com 100319475328460011057 100319475328460011057 Yes دانشگاه زنجان Mohammad Babaakbari محمد بابااکبری Babaakbari@znu.ac.ir 100319475328460011058 100319475328460011058 No دانشگاه زنجان Akbar Hassani اکبر حسنی Akbar.Hassani@znu.ac.ir 100319475328460011059 100319475328460011059 No دانشگاه زنجان Milad Pero میلاد پرو M.Pero@zarholding.com 100319475328460011060 100319475328460011060 No دانشگاه زنجان Setareh Amanifar ستاره امانی فر Amanifar@znu.ac.ir 100319475328460011061 100319475328460011061 No دانشگاه زنجان
