Abstract
This study was conducted in a private field in Basrah AL-Qurna for the growing season 2022-2023 to study the effect of the hormone brassinolide, hydrogel polymer and two different watering periods on some anatomical characteristics of okra leaves. The experiment included a study of the effect of three factors: (BR) at two concentrations (3, 6) mg/l, (SAP) at two concentrations (50, 100) g/ m² soil, and two watering periods (3, 6) days. The experiment was designed depening on the complete random block design (R.C.B.D.) with three replicates for each treatment, and the least significant difference test was (0.05). The results showed that the treatment of plants with the (BR) led to a significant increase in all the studied characters, as the (SAP) had a significant effect on all the studied traits, and the binary interactions significantly affected all the studied featuers. In conclusion, significant increase occurred in all studied traits at a hormone concentration of 6 mg/ l and a polymer at a concentration of 100 g/ m² soil and an irrigation period of 3 days compared to the control treatment and an irrigation period of 6 days. Keywords: Okra plant, Brassinolide hormone (BR), Hydrogel polymer (SAP), Irrigation periods.
