Effect of Spraying with Different Concentrations of Organic Fertilizer Nutrigreen and Salicylic Acid on the Vegetative Growth of Two Cultivars of Gladiolus hybrid L

The experiment was carried out inside the wooden canopy of the Department of Horticulture and Landscaping / College of Agriculture and Forestry / University of Mosul during the period from 17 March to 10 October 2022 in order to evaluate the response of two varieties of Gladiolus X hortulanus L. They are: White Prosperity with white flowers and Plumtart with flowers Purple for treatment with Nutrigreen organic fertilizer in three concentrations: zero, 1000- and 2000-ml. L -1 , as well as treatment with salicylic acid in three concentrations, 500 and 1000 mg. L -1 sprayed on the shoots three times. In the implementation of the experiment, the factorial experiment with a randomized complete block design (RCBD) was used in split plots (Factorial Experiment with in split plot) with three replications and 7 treatment plants. The results indicated that the white cultivar recorded the largest plant height 136.596 cm, while the purple cultivar plants recorded the largest values for the leaf length per plant 86.312 cm and the number of leaves per plant 8.206 leaves. Plant -1 , the leaf area of the plant was 484.472 (cm 2 ), and the dry weight of the leaves was 16.559 (g).
