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 .
