Abstract
The study was conducted in the wooden canopy of the Department of Horticulture and garden Engineering / College of Agriculture / University of Tikrit during the 2021 agricultural season, in order to study the effect of spraying with glutamic acid and Nano-zinc oxide on some vegetative growth characteristics and mineral content of Lavendula Angustifolia Mill plant. A factorial experiment was carried out with two factors, the first factor of glutamic acid with three levels (0, 100, and 200) mg. L1- The second factor is Nano zinc oxide at four levels (0, 0.50, 1, and 1.50 g). L1 - According to the design of the full randomized RCDB sectors (Randomized Complete Block Design) and three duplicates, the most important results are summarized as follows: Characteristics of vegetative growth: The transaction G2 was characterized by giving the highest differences in plant height, the number of leaves, and total chlorophyll content, which amounted to 32.475 cm and 876.12 leaves. Plant-1, 35.128 mg. gm 1-soft weight, respectively, compared to the lowest values for the above-mentioned traits for the comparison transaction.
