Background and Objective: Abiotic stress (drought and the low nutrients of sandy soils) affecting on plant growth and yield. The foliar application of natural antioxidants compounds considered one of the methods to avoid the deleterious effects of such stress conditions. The present work implemented to find out the effect of spraying aspartic acid, coumarin and benzoic acid at different concentrations on growth, yield, some physiological criteria and quality traits of flax seed yield grown under sandy soil conditions. Materials and Methods: The experiment conducted in randomized complete block design with three replications. The concentrations for foliar applications with aspartic and benzoic acid (50, 100 and 200 mg L–1) and coumarin (25, 50 and 100 mg L–1) were distributed at random in the plots. Results: The studied growth criteria and photosynthetic pigments increased significantly with the application of aspartic acid, coumarin and benzoic acid. Aspartic acid at 100 mg L–1 was the most effective treatment followed by 50 mg L–1 benzoic acid in most cases of the tested parameters. The highest value was observed in response to benzoic acid in total soluble sugars, proline and free amino acid. Aspartic acid spraying induced the highest values of total phenols, IAA, DPPH% and total soluble protein. Aspartic acid was the superior in affecting yield, yield components and the nutritive value of flax followed by coumarin and benzoic acid. Conclusion: The obtained results suggested that the use of aspartic acid at 100 mg L–1 was promising in alleviating stress on flax and improved the yield and nutritive value of its seeds.
