Salinity is one of the major problems which ultimately leads to yield loss among important crops. For all major crops, average fraction of harvested area – between 20% and 50% of record yields; these losses are due to drought and high salinity of the soil. A wide range of strategies are needed to manage such effects. It is necessary to develop biological methods for managing salt stress that are simple and inexpensive. There are a range of plants recognized as glycophytes, which are salt sensitive and. Generally, our main crops are glycophytic in nature. Parsley (Petroselinum crispum) is a biennial herb belonging to the Apiaceae family and has higher medicinal values ​​and as a seasoning as well as a garnishing agent in the food industry. It can grow dynamically in harsh environment and due to scarcity of nutrients. Although P. crispum has been widely explored for its medicinal values, say no to plagiarism.

Introduction The 21st century is characterized by international water shortage, polluted environment and salinization of soil and water. There are two threats to agronomic sustainability, namely increasing human population and decreasing accessible land (Shahbaz et al., 2013). One of the main reasons for natural soil salinity is the fluctuation of the water table. As the water table fluctuates, crops cannot use a significant volume of water. As a result, the soil allows greater precipitation penetration and causes a rise in the water table (Jardine et al. 2007), which ultimately increases the salinity problem. Natural salts are mobilized and rise to the surface, causing salt deposition to increase above natural levels (Mills et al. 2016). In most regions, the problem of soil salinity is due to the rapid expansion of irrigation (Shrivastava et al., 2015). Anthropogenic origin is the other major cause of soil salinity. The use of inappropriate cultivation techniques, intensive use of fuels, increasing number of industries and urban water use have led to the deposition of large quantities of salt in the upper soil layer (Sytar et al ., 2018). Soil salinity, mainly NaCl, limits growth. and the production of many cultivated plants. Salinity not only reduces crop yield per hectare, but also decreases arable land. These losses are compounded by the additional challenges that agriculture requires to provide sufficient food for the world's population (with a superior lifestyle) which is growing at an alarming rate (Schroeder et al. 2013). Higher concentration of NaCl in plants mainly induces osmotic effects and/or ionic stresses which ultimately lead to secondary stresses, i.e. oxidative and related stresses (Flowers et al., 2008). To survive with unfavorable Na+ concentration, the plant uses various approaches to maintain a low level of cytosolic Na+. These approaches include: 1. Reduced entry of Na+ into plant cells 2. Compartmentalization of Na+ into the vacuole 3. Efflux of Na+ from the root tip (Aharon et al.,..
