The field experiment was conducted in the Saran-covered canopy belonging to Agricultural Preparatory School, Abi Gharq for the spring season (2018-2017) to study the effect of antioxidants (Vitamin E, salicylic acid and selenium) on the tolerance of the Senna coffee plant to salt stress.

The seeds of Senna coffee was obtained from a plant grown in a home garden in Baghdad.

The study was conducted to study the effect of saline stress at two levels of well water (4, 8 dS.

m-1), in addition to the water of control treatment (Tap water) and spraying three factors of antioxidant (200 mg.

L-1 salicylic acid and 150 mg.

L-1 vitamin E and 173 mg.

L-1 selenium) as well as the control treatment of and interactions between factors in the growth and flowering of the Senna coffee plant and its content of active compounds.

It was observed that irrigating with well water at a salinity of (4, 8 dS.

m-1) led to a significant decrease in all the vegetative and flowering traits for the Senna coffee plant.

The spraying with selenium, vitamin E and salicylic acid was significantly affected in improving the most studied traits of Senna coffee plants.
