Maize (Zea mays), initially domesticated in Central America, is the world's leading crop and is widely cultivated as a cereal grain. It is one of the most versatile emerging crops with wide adaptability. Ascorbic acid was applied to the plants growing under control, 60 and 120 mM NaCl, in two ways: as a foliar spray on leaves or through roots in the soil at two levels, 100 and 150 ppm. At UAF Community College PARS, a pot experiment with three replicates was conducted using a CRD with a factorial layout to investigate the influence of ascorbic acid on a variety of physiological and morphological parameters. After the application of NaCl treatment, various parameters were recorded, like shoot attributes, root attributes, and photosynthetic pigments; nutrient analysis was conducted using a standard procedure. NaCl significantly reduced the growth of the plants. All the considered parameters showed negative growth with high NaCl, but the application of ascorbic acid improved and alleviated the effects of NaCl toxicity on all parameters, except in the roots, where salt accumulated, leading to non-significant results. The leaf area index, root length, shoot length, per plant leaves, maximum plant height, (a and b) carotenoids, SOD, POD, MDA, BOD, CAT, chlorophyll content, nitrogen content Na⁺, K, Ca^2+, protein content, and soluble sugar are some of the parameters that were measured. The collected data was scrutinized using COSTAT software, and treatment means were compared using the LSD test with a probability level of at least 5%. Moreover, Tukey's test was applied to compare the means of the samples.
