Abstract

Climate variability presents a significant challenge to global food security in arid and semi-arid regions. A field experiment was conducted at the Experimental Farm of the Faculty of Environmental Agricultural Sciences, Arish University at North Sinai in Egypt. The aim of this study was to test and evaluate the effect of the applied foliar application of seaweed extract (SWE) and selenium-nanoparticles (Se-NPs), individually and in combination, on improvement of vegetative growth and yield of quinoa cultivar (Masr3) across two successive growing winter seasons. A randomized complete block design in a split-plot arrangement was followed with two levels of SWE (0 and 3000 mg/L) and four Se-NPs concentrations (0, 0.5, 1.0, and 2.0 ppm). The results indicated that both SWE and Se-NPs significantly enhanced vegetative and yield traits, with the combined application producing the highest performance across all parameters. Also, the foliar co-application of seaweed extract (3000 mg/L) and nano-selenium (2 ppm) appeared a highly significant enhancement in both vegetative growth parameters and yield components, highlighting a synergistic effect that increased physiological activity, nutrient uptake, and plant productivity. Therefore, integrating bio-stimulants, such as seaweed extract, with low-dose nano-selenium offers a sustainable strategy for improving quinoa productivity under climate stress is suggested. The combined use of natural and nano-based foliar sprays holds potential for broader application in climate-smart agriculture.
