Abstract

The experiment was carried out in the field belonging to the Botanical Garden belonging to the Department of Biology, College of Education for Pure Sciences (Ibn Al-Haitham), University of Baghdad, for the growing season 2021-2022 to study the effect of bio-fertilizer (AG 8-1-9) in three concentrations (0, 3, 6) mg.L-1 and brassinolide hormone in four concentrations (0, 2, 4, 6) mg. L-1 and its interactions in some growth parameters and total chlorophyll of two varieties of Medicago sativa plant. The experiment was designed according to Randomized Complete Blocks Design (R.C.B.D.) with three replicates per treatment. The averages were compared using the least significant difference at the probability level (0.05), and the results showed the following:
