“…SA also has a crucial function in the mechanism of plant water stress tolerance. Exogenously applied SA has been reported to influence uptake and transport of nutrients (Kaydan, Yagmur, & Okut, 2007), stomatal regulation (Heidari et al, 2020;Janda, Gondor, Yordanova, Szalai, & Pal, 2014), growth and photosynthetic rate (Li et al, 2014;Mohammadi, Shekari, Saba, & Zangani, 2017) and chlorophyll synthesis (Abdolahi, Shekari, Saba, & Zangani, 2018;Heidari et al, 2020). Thus, it may be concluded that SA when applied acts as a regulator that potentially affects the growth and productivity in plants (Ashraf, Akram, Arteca, & Foolad, 2010).…”

Inducing tolerance against drought stress with plant growth regulator and plant nutrients is vital for ensuring food security and sustainable crop production. The present study was undertaken to assess the influence of salicylic acid (SA) either seed primed or foliar application (1.1, 2.2, 0.7 and 1.4 mM SA) coupled with potassium (K) fertilisation (0, 50 and 100 kg/ha) on wheat yield and nutrients uptake under drought stress (100% field capacity [FC], 60% FC, 30% FC) at tillering stage. Findings revealed that drought stress substantially reduced yield components, yield and grain nutrients content and uptake, whereas the potassium use efficiency (KUE) and antioxidant profile was improved. However, the foliar application of 0.7 mM SA and 1.1 mM SA as seed priming had increased number of spikes, thousand grain weight, grains per spike, grain and biomass yield, N, P, K content and K uptake, KUE and antioxidant profile both under no stress and drought stress treatments indicating the key role in ameliorating the ill effects of drought stress as compared with no SA application. Moreover, K fertilisation at 100 kg/ha had improved growth, yield and yield components, plant nutrient uptake and antioxidant profile except proline under both no stress and mild stress as compared with no K application. These results suggested that the combined use of SA either as foliar or seed primed with higher K fertilisation can substantially improve wheat yield, and grain nutritional content under mild and severe drought stresses.

The purpose of this study was to investigate the impact of salicylic acid (SA) on wheat subjected to cadmium (Cd) stress. The experiments were conducted during the winter season of 2022‐2023 (November to February) at the University of the Punjab in Lahore, Pakistan. The study involved four wheat varieties: Akbar‐2019, Galaxy‐2013, Ujala‐16, and Chakwal‐86. The study utilized a factorial design with three replicates, examining three Cd levels (0.1 mM, 0.2 mM, and 0.3 mM) and two SA levels (0.5 mM and 0.9 mM). SA was applied as a seed priming agent, while cadmium sulfate (CdSO4) solution induced Cd toxicity. Various growth parameters, including plant height, total plant length, leaf length, leaf breadth, and leaf area, were measured alongside physiological and biochemical parameters such as total chlorophyll content, carotenoid content, oxidative stress indicators (MDA and H2O2), and antioxidants (total soluble protein, CAT, and APX)—to assess the effects of SA under Cd stress. The results indicated that the application of 0.5 mM SA resulted in the highest vegetative growth and maximum physiological and biochemical parameters, while 0.3 mM Cd significantly reduced growth. The performance of the treatments was observed in the following order: 0.5 mM SA > 0.3 mM Cd. Ujala‐16 showed intermediate growth and yield, while Chakwal‐86 had the lowest growth rate and yield. The study demonstrated that SA mitigates Cd stress effects, with 0.9 mM SA and 0.1 mM Cd yielding the highest growth, second only to 0.5‐ and 0.9‐mM SA treatments. These findings underscore the potential of SA to enhance wheat growth and yield in Cd‐contaminated soils. In conclusion, SA is suggested as a beneficial treatment for improving productivity and economic returns in Cd‐stressed areas. Future recommendations include conducting long‐term studies to evaluate cumulative treatment effects and investigating how salicylic acid mitigates cadmium stress through biochemical pathways and gene expression, enhancing agricultural practices.
