Effect of Foliar Application of Zinc Oxide Nanoparticles on Selected Vegetative Growth Traits of Two Garlic (Allium sativum L.) Cultivars

Abstract

The purpose of the experiment was to find out how the vegetative growth characteristics of two garlic cultivars were affected by ZnO nanoparticles. Using a randomized complete block design (RCBD), the research examined two primary components and their interactions, with three replicates for each factor. The compatibility of two garlic cultivars with four concentrations of ZnO nanoparticles (0, 50, 100, and 150 mg/L) led to the inclusion of 24 experimental units in the study. The Iraqi Local Garlic variety (49.225cm, 5.475 branch number, 376 555 cm²) was superior in height, number of branches, and leaf area, respectively, compared to the Persian (Iranian) variety (47.25cm, 4.107 branch number,347.667 cm²). The 150 ZnO nanoparticles concentration (50.275 cm, 5.175 number of branches, 998.18 cm²) was superior in height, number of branches, and leaf area, respectively, compared to the control treatment. As for the bilateral interaction between the variety and the concentration of ZnO nanoparticles, the treatment of the local variety and the concentration of ZnO nanoparticles was superior to 150, concentration (51.25 cm, 5.75 number of branches, 545.70 cm²) was superior in height, number of branches, and leaf area respectively compared to the control treatment.
