Abstract
The experiment was carried out in the lath house at the Horticulture and Landscaping Department/College of Agriculture/University of Diyala, during the season 2015-2016 to study the effect of chelated calcium and iron foliar spray on growth and flowering of snapdragon plant (Antirrhinum majus L.). The experiment included six treatments: T1 = 0 (Spraying with distilled water only), T2 = 1.5 g.l-1 chelated calcium, T3 = 3 g.l-1 chelated calcium, T4 = 1 g.l-1 chelated iron, T5 = 1.5 g.l-1 chelated calcium + 1 g.l-1 chelated iron and T6 = 3 g.l-1 chelated calcium + 1 g.l-1 chelated iron. The experiment was carried out using Randomized Complete Block Design (RCBD) with three replications. (Each treatment has six replicates (6 pots), one plant in each pot. The results showed that all the foliar spraying treatments with chelated calcium and iron led to a significant increase in all vegetative and floral growth characteristics studied except for inflorescence diameter in comparison with control treatment.
