The study was conducted at the Botanical Garden for Department of Biology, College of Education for Pure Science (Ibn Al-Haitham), University of Baghdad for the growing season (2016-2017) in order to study the chelating compound DTPA effect at different concentrations (0, 5, 10, 15, 20) mg.L-1 and growth organizer brassinolide at concentrations (0, 0.5, 1, 1.5, 2) mg.L-1 and their interaction on some morphological properties and content of macroelement (nitrogen, phosphorus, potassium) for coriander plant. Randomized complete Block Design (RCBD) was tested with three replicates. The results showed that the application by (DTPA) act to an increase in the mean of stem diameter and the total chlorophyll content in the leaves and concentration of nitrogen and potassium at the concentration of 20 mg.L-1 while no a significant effect on phosphorus concentration compared to the control treatment. Brassinolide increased all the studied characteristics of stem diameter, total chlorophyll content in leaves, concentration of nitrogen and concentration of potassium at concentration of 2 mg.L-1, while it did not have a significant effect in phosphorus concentration compared to control treatment.

The results also showed a significant interaction between the factors of experiment in all the studied characteristics at the concentrations 20 mg.L-1 from DTPA and 2 mg.L-1 from brassinolide except of phosphorous which showed a significant interaction at concentrations 20 mg.L-1 from DTPA and 1, 1.5 mg.L-1 from brassinolide.
