The present study investigates how Potassium chloride (KCl) affects and alters the biochemical and morphological characters of Triticum aestivum L variety (Ghanimat). The experiment was arranged in Randomized Complete Block Design (RCBD) under the natural light condition. Potassium chloride (KCl) applied as foliar spray at the dose of (20, 40, 60, 80, and 100 ppm) on wheat plant. Morphological parameters including shoot length, root length, fresh and dry weight, relative water contents, leaf area, leaf no, root no were analyzed along with biochemical contents including Chlorophyll a b, protein, proline, sugar, carotenoid, phenol and amino acid contents. Results showed that the maximum concentration of morphological parameters observed at different applied potassium chloride but maximum morphological parameters are high in (control 20, 40, and 60 ppm). Biochemical contents show that maximum concentration of Chlorophyll a b, protein, proline, sugar, carotenoid, phenol and amino acid contents observed in (control 100, and 40 ppm). The current study revealed that KCL deficiency as well as excess concentration affects plant growth and various morpho-physiological processes. The usage of optimum KCl we can improve the T. aestivum L quantitatively and qualitatively.
