| The present research aimed to study the Physiological Response of different Chickpea genotype to Foliar Application of Gibberellin. it was conducted during 2025–2026 growing season as field trial at Al-Bu’aitha Research Station, College of Agriculture, University of Anbar. The experiment was implemented according to a randomized complete block design (RCBD) in a split-plot arrangement with three replicates. The main plots represent four doses of gibberellin (0, 100, 200, and 300) mg L-1, whereas the subplots included three cultivars of chickpea (G1, G2, and G3). The results showed the superiority of the plants of the genetic structure G2 in the traits of dry weight, leaf area, chlorophyll content, relative growth rate, crop growth rate, and net assimilation rate, as it gave averages of 16.21 g plant-1, 1116.6 dm2, 1.82 mg g-1, 0.01720 g day-1, 0.2140 mg cm-2 day-1, and 0.3009 mg cm-2 day-1, respectively. Gibberellin concentrations significantly affected the studied traits, as the concentration of 100 mg L-1 showed significant superiority in all studied traits, reaching 17.36 g plant-1, 1207.4 dm2, 2.05 mg g-1, 0.0176 g day-1, 0.2267 mg cm-2 day-1, and 0.3295 mg cm-2 day-1, respectively. The interaction between the two study factors also significantly affected all studied traits, as the treatment of 100 mg L-1 in interaction with the genetic structure G2 gave significant superiority in the traits of dry weight, leaf area, chlorophyll content, relative growth rate, crop growth rate, and net assimilation rate, with averages of 17.97 g plant-1, 1226.4 dm2, 2.29 mg g-1, 0.0181 g day-1, 0.2358 mg cm-2 day-1, and 0.3430 mg cm-2 day-1, respectively. | ||
