Physiological response of sweet corn (Zea mays Ls.) grown under sandy soil to α-tocopherol treatments and different irrigation systems

Abstract Background Antioxidants or vitamins are organic compounds that needed in tiny quantities and have stimulatory role on growth productivity of different plants. Two field experiments were conducted two summer seasons to investigate the irrigation systems (spraying dripping) α-tocopherol foliar treatment with concentrations (0, 100 200 mg/L) some indices physiological aspects, yield its components sweet corn Results The results show dripping system was more effective than Sprinkler increasing studied biochemical attributes as well quantity quality. also enhancing effect treatments indices, quality varieties via photosynthetic pigments, indole acetic acid, phenolics, carbohydrates constituents, free amino acids proline contents. Moreover, interaction between showed that, mg/L most growth, Conclusion It could be concluded constituents. maize plant improve aspects consequently yield.
