“…Cell division rate in roots of onion plants was reduced by high salt concentrations, hence the plant growth and productivity was reduced significantly (Singh and Roy, 2016). However, to mitigate the impact of salt stress on plant growth and development, different strategies have been used including intercropping with halophyte species (Lastiri-Hernández, 2021), antioxidant compound (Mohamed and Aly, 2008) and plant growth regulator and widely applied salicylic acid (SA) (Ashraf et al, 2010 andda Silva et al, 2019). SA is known to reduce biotic and abiotic stress in plants by activation of the defense system (Wani et al, 2017).…”

Soil salinity negatively affects crop production and leads to loss of agricultural lands worldwide. In Iraq, poor agricultural practices, such as inadequate drainage facilities and low water quality, are known to be caused soil salinization. Onion (Allium cepa L.) is an economic crop that is consumed heavily as green or dry bulb onion. The cultivated area of green onion was statistically decreased in the Kurdistan region, Iraq, lately. Therefore, this study was conducted in the Directorate of Agriculture, Ankawa, Erbil, to examine whether salicylic acid (SA) mitigate the effect of salt stress and improve the growth and development of green onions. Two different concentrations of NaCl (20 and 40 mM) were injected around the base of each plant and after 24h, SA (0.5 and 1mM) was sprayed to the vegetative parts of each plant, evenly. The results showed that the short-term application of SA was reduced the impact of NaCl. The number of green leaves, leaf area, plant height, root growth, bulb diameter, plant weight and total yield (t. ha-1) was improved by the application of SA. It has been suggested the application of a commercial or SA analogue to the agricultural saline land may alleviate the salt stress and improve the product.
