EFFECT OF NANO-IRON AND NANO-ZINC ON SOME GROWTH CHARACTERISTICS, CHEMICAL COMPONENTS AND OIL OF BASIL PLANT (OCIMUM BASILICUM L.)

Abstract

This study was carried out in an agricultural field in the College of Agriculture and Marshes - Thi-Qar University. The experiment aimed to investigate the effect of Nano-iron and Nano-zinc on the vegetative growth characteristics, chemical components and oil of basil plant. The study included two main factors and their overlap with three replications for each factor using a randomized complete block design (RCBD). The study included twenty-seven experimental units resulting from the compatibility of three concentrations of iron (0, 30, and 60) mg L -1 and three concentrations of zinc (0, 20 and 40) mg L -1 . The results showed that the Fe2 treatment was superior to the Fe1 treatment and the control treatment in terms of plant height, number of leaves, number of branches, leaf content of chlorophyll and carbohydrates, and the percentage of oil, which were (61.56 cm, 92.49 g, 12.60 branches, 15.71 mg100 g-1 fresh weight, 172.4 mg g -1 dry matter and 10.57%) respectively. While the Zn2 treatment was superior to the Zn1 treatment and the control treatment in each of the plant height, the number of branches, the number of leaves and the highest percentage of oil with averages of (54.74, 85.28, 10.73 and 9.215%), while it was not significant in the content of each of the leaves of total chlorophyll and carbohydrates. The interaction treatment Fe2Zn2 was superior to the control treatment H0N0 and the rest of the treatments in the study in plant height, number of leaves, and percentage of oil only, but it was not significant in the rest of the studied trait characteristics.
