Antioxidants protect the body against cancer, cardiovascular disease, rheumatoid arthritis (arthritis), aging, brucellosis, Alzheimer's, stroke, type 2 diabetes, inflammation and infection, and generally strengthen the immune system. This study was carried out to evaluate the amount of plant antioxidants in comparison with nano-chelated nitrogen and urea fertilizers in wheat under drought stress in Koodian and Nasrabad regions of Fars province.The experiment was conducted as a split-plot design in a randomized block design. The main factor included irrigation treatment (normal irrigation and no irrigation at flowering stage) and sub factor included nitrogen treatment (0, 37, 74 and 110 kg / ha) as urea fertilizer, and subfactor included nitrogen (0, 14, 27 and 41 kg / ha) was chelated as nano-nitrogen fertilizer. The studied traits were chlorophyll a and b, anthocyanin, carotenoid, flavonoid and proline. Using nano fertilizers at 240 kg / ha compared to the same amount of urea can increase anthocyanins by up to 24%, carotenoids by up to 8%, proline by up to 15%, flavonoids by up to 13%, and chlorophyll a and b by up to 60%.
