A field experiment was carried out in Diyala Governorate during the winter season 2020-2021 to evaluate the effect of spraying three concentrations of Brassinolide hormone (1, 2 and 3 ppm) in addition to the control treatment (0 ppm) and three dates of spraying (after 20,40 and 60 days of germination) in the production of oil and total glycosides in Securigera securidaca seeds, by using a factorial experiment according to the randomized complete block design. The results showed that the spraying treatment with a concentration of 2 ppm was superior in seed yield, content and yield of oil, and content of total glycosides in the seeds, which reached 9.76 g/plant, 4.00%, 15.43 kg/ha and 1.770 mg/100 g seeds respectively, while the second date of spraying with the hormone Brassinolide was superior in seed yield, content and yield of oil, and total glycosides, reached 9.39 g/plant, 3.76%, 13.15 kg/ha and 1.750 mg/100 g seeds respectively. The results also show that the interaction treatment was superior at concentration 2ppm in the second date and gave the highest content and yield of oil and total glycosides which reached 4.24%, 17.54 kg/ha and 1.820 mg/100 g seeds respectively.
