“…Salt stress can be caused by climate change, low-quality irrigation water, and inadequate doses or management of fertilizers such as potassium chloride (KCl), one the most used source of K in World (Yuan et al 2019; Malakar and Chattopadhyay 2021). When the concentration of solutes in the soil increase causes greater difference on ionic component, which reduces the osmotic potential, inducing water de cit (Lefèvre et al 2001;Irakoze et al 2022), harming water relations and plant morphophysiology.…”

Salinity can be stressful and impair water relations and the germination of soybean seeds, making it necessary to establish sustainable solutions to overcome this situation. We hypothesized that seed priming (SP) with Parachlorella sp. microalgae can reduce the stressful effects of salinity and contribute to seed germination and seedling growth, inducing tolerance. We aimed to evaluate the constituents of Parachlorella sp. biomass and potential of SP in soybean to mitigate the effect of salinity on germination and vigor. Seeds were subjected to the following priming: i) without priming, ii) priming with 5 mL, and iii) 10 mL kg seed-1. Then, seeds were subjected to four osmotic potentials: 0.0 (control), –0.4, –0.8 and –1.2 MPa, induced by KCl. Parachlorella sp. biomass contained several metabolites such amino acids, carnitines, lipids, and phytohormones. The maximum percentage of normal seedlings was in –0.79 MPa. Seed without and with 5 and 10 mL of Parachlorella sp. showed higher root protrusion at –0.71, –0.37 and –0.30 MPa, respectively. Priming with 5 and 10 mL of Parachlorella sp. resulted in greater root protrusion in seeds not exposed to salinity. Seedlings from seed that received Parachlorella sp. showed greater growth even under salt stress. Priming with 10 mL of Parachlorella sp. resulted in seedlings with greater biomass accumulation at –1.2 MPa. Priming contributed to the lower electrolyte leakage in –1.2 MPa. Although soybean is sensitive to –1.2 MPa, SP with 10 mL of Parachlorella sp. microalgae demonstrated to be a sustainable and efficient alternative to mitigate the stressful effect of salinity on seedling vigor.

“…Cltoxicity developed due to soil salinity is not only a thread to food security but it also affects the aesthetic values of ornamental plants leading to decrease its marketable values. The toxicity effect of chloride is more severe than sulphate in saline soil (Irakoze et al, 2022). It has been reported that half the concentration of chloride toxicity is equal to full concentration of sulphate.…”

Soil salinity is associated with the accumulation of soluble salts in higher concentration deteriorating soil health associated with unfavourable environment for plant growth. It is mostly confined to those regions where there is high temperature and low precipitation, mostly in arid and semi-arid regions. Major factors responsible for soil salinity can be categorised into primary and secondary factor affecting at the spatial and temporal scale. Higher concentration of soluble salts in soil increase the osmotic potential disrupting the movement of water from root to leaf. So, soil salinity is primarily associated with the water stress condition in plants which is a direct impact to plants. Indirectly it interferes with the nutrients absorption which is one of the most important factors for proper plant growth. Plants poses different mechanisms to avoid salt stress condition in soil but maximum of it are an active processes were additional energy must have to spend for it that can impact proper growth and production. The ions primarily responsible for both the soil and plant stress under soil salinity are Na+ and Cl- which concentration increases with certain primary and secondary soil salinization factors. So, primary aim to control the impact of soil salinity is to reduce the activity/concentration of both Na+ and Cl- from the soil. So, use of the essential nutrients (K+ and SO4-2) that has an antagonistic relationship with the salts is a new approach. Due to similar charge and physico chemical properties of K+ and SO4-2 with toxic ions Na+ and Cl- respectively, there lies an antagonistic relationship. Furthermore, SO4-2 of its less toxicity to plants and improve soil pH condition especially in arid and semi-arid region, the combination of K+ and SO4-2 salt is a good combination to ameliorate the Na+ and Cl- toxicity under saline soil.

Environmental stress is a global threat to provide the world’s food. Drought and salinity are the main threats to agricultural land productivity. This is a challenge in implementing SDGs 2030 as well as an opportunity if we are able to use germplasm to overcome various environmental stresses. Research on 2 varieties of rice Inpari 42 agritan as a comparison variety and varieties Sigupai which is a local variety of Aceh originating from Abdya. This study used a 2x3x6 split plot design with 108 experimental units and 324 experimental pots. There is an interaction between varieties when salinity occurs and salinity level on the growth of rice plants in the vegetative phase and electrical conductivity in soil and water which shows different responses between the Inpari 42 Agritan variety and the Sigupai varieties. On the electrical conductivity of the Sigupai. variety, it was better able to reduce Ec at different levels of salinity and time of occurs in the vegetative phase. Meanwhile, Inpari 42 Agritan is more capable of increasing growth under conditions of increased salinity in the vegetative phase. The local variety Sigupai, the rate of growth reduction is also relatively low compared to that without salinity. This is an opportunity to deal with drought and salinity that can occur anytime and anywhere due to drought, water management and improper fertilization that can occur anywhere. It is a challenge to overcome drought and lowering salinity with the use of local varieties and appropriate agronomic practices.
