Melatonin fights the oxidative damage caused by drought and stimulates growth, productivity and quality characteristics of tomato fruits. Melatonin fights the oxidative damage caused by drought and stimulates tomato growth, yield, and quality characteristics. Although many previous studies have confirmed that exogenous magnetic therapy used can relieve the negative effects of drought stress on many plant species, most of these studies were conducted exclusively on seeds, seedlings and young plants within a short period of their life cycle. These results indicate that exogenous TMs play an important role in increasing tomato tolerance for poor irrigation and may be recommended as a promising treatment in agriculture under these conditions. In this study, we investigated the effect of magnetic therapy on non-root application at 0, 20 and 40 ppm on tomato plants grown in the field under optimal irrigation conditions and under poor long-term irrigation conditions. Therefore, knowledge about the use of magnetic therapy as a potentially promising non-root application in agriculture to improve yield and plant quality under poor field conditions is still insufficient.
