Abstract: 

The research was carried out during the agricultural season for the year 2022 on a private farm in Deir Ezzor Governorate, the aim of studying is the effect of suppressing the growing top with different dates (0,40,55,70) days of cultivation and spraying dry baking yeast with concentrations (1.5-3-4.5)g/liter in addition to treatment The non-sprayed control of some characteristics of vegetative growth and yield of okra, the local cultivar (Almothaman). The results showed that the plants whose growing tops were pinched off at the first date, in terms of the number of leaves, their content of chlorophyll, and the productivity of one plant over the rest of the dates (86.25 leaves / plant – 296.60 mg/100g- 752.82 g/plant (while the second date was superior in terms of the number of fruits (98 fruits/plant) as the uncrushed control showed the highest height of the plant. With regard to spraying with dry yeast, there was an increase in all traits with increasing concentration and with all treatments, and the effect of overlap Between vetting at the first date and spraying with a concentration of 4.5g/liter was significant in all traits except for number of fruits, where it reached the highest value at the time of the second vetting with the same concentration and the characteristic of plant height, where it reached the highest value in plants that were not mowed and sprayed with a concentration of 4.5g/liter.

Keywords: Dates of growing point pinching, dry yeast, okra.
