Abstract: (10 Views)
Finding sustainable and environmentally friendly strategic approaches to increasing food production is of vital importance for future food security. The use of nanotechnology is a promising approach in agriculture. However, determination of efficient and cost-effective concentrations according to the desired plant species needs further investigation. Therefore, the current study was conducted with the aim of evaluating the effect of nano-zinc oxide on the growth and physiological traits of maize plants in the spring of 2023 in Zahedan city. The experiment was conducted as a factorial design in a randomized complete block design with four replications. Zinc foliar spray treatment in the form of zinc oxide at four levels (distilled water (control), 0.3, 0.6, and 1.2%) was considered the first factor, and nano zinc oxide treatment at four levels (distilled water (control), 0.025, 0.05 and 0.1%) was considered the second factor. The results showed that the investigated traits were significantly affected by zinc oxide and nano zinc oxide. Means comparison of interaction effects showed that the highest dry matter yield (6802.5 kg/ha), grain yield (2340 kg/ha), and protein content (5.8 mg/g fresh leaf weight) were obtained from the foliar spray treatment of 0.06% zinc oxide together with 0.1% nano zinc oxide. The highest activities of the enzymes' catalase, guaiacol peroxidase and superoxide dismutase enzymes were 1.36, 0.299 and 1.05 per minute per mg of protein, respectively. The highest amount of catalase in the foliar treatment is 0.6% normal zinc oxide along with 0.05% nano zinc oxide; the amount of guaiacol peroxidase in the foliar treatment is 0.6% zinc oxide along with 0.025% nano zinc oxide; and the amount of superoxide dismutase in the foliar treatment is 0.3% zinc oxide together with 0.025% nano zinc oxide was observed. According to the findings of the research, foliar spraying of 0.6% zinc oxide together with 0.1% nano zinc oxide is suggested to improve the quantitative and qualitative traits of the maize plant.
