| Abstract | ||||
| Increasing irrigation intervals (every 14, 16, 18 or 20 days ), decreased growth parameters as well as yield and its components of maize plants throughout the hole experimental periods during the two growing seasons ( 2007& 2008 ). Irrigation every 20 days was the most effective treatment in decreasing growth , yield and its component of maize plants. According to antioxidants, the the results show that applied antioxidants Citric acid, Ascorbic acid or Sea weed extract increased all growth parameters , yield and its components of maize plants.Sea weed extract was the most effective in this respect. The interaction effect between irrigation intervals and antioxidants substances show that the applied antioxidants enhanced all growth parameter as well as yield and its component of maize under drought stress. It could be concluded that applied antioxidants could partially counteract the harmful effect of drought stress (irrigation every 16, 18, 20 days ) on growth as well as yield and its component of maize plant . | ||||
