A field experiment was conducted during the 2022 growing season at the Qlyasan Research Center, College of Agricultural Engineering Sciences, to investigate the effects of foliar application of seaweed extract (SE) on the phenological, physiological, biochemical, and reproductive traits of wheat. The study involved four wheat varieties (Sulaimani-2, Rizgari, Alaa, and Hasad) and three SE concentrations (0.0, 1, and 2g L⁻¹), arranged in a randomized complete block design with three replications. Results showed that the highest SE concentration (2g L⁻¹) significantly enhanced plant height, flag leaf area, specific leaf area, dry matter accumulation, root-shoot ratio, and relative growth rate. Reproductive parameters such as spike length, number and weight of spikes per m², spikelets per spike, grain number and weight, grain yield, biological yield, and harvest index also improved. Furthermore, increasing SE concentration positively influenced physio-biochemical traits, including soluble sugar content, total chlorophyll content, carotenoid content, and protein percentage. The interaction between SE levels and wheat varieties was significant across all traits, with Rizgari showing the most pronounced response, likely due to its superior morphological features and genetic capacity for nutrient uptake and physiological efficiency.
