| Abstract | ||||
| In Egypt, we are under the water poverty limit. Therefore, practical solutions must be undertaken to confront the water scarcity, which hinders agricultural development in Egypt. For this purpose, two field trials were performed to assess different irrigation intervals as main plots (irrigation every 8, 10 and 12 days), soil conditioners as subplots [ without (control), biochar and compost] and foliar application of ascorbic acid at different rates (0.0, 5.0 and 10.0 mM) as sub-sub plots on maize plant performance and yield. Findings showed that deficit irrigation (irrigation every 10 and 12 days) caused a significant decline compared to irrigation every 8 days. Both soil conditioners improved plant performance and increased yield and quality of maize compared to plants grown without soil conditioners, but compost was more effective than biochar as a soil amendment in this regard. Also, the external application of ascorbic acid possessed a vital role in hindering the hazard effect of drought treatments, where plant performance and its yield increased as the rate of ascorbic acid increased. On the other hand, drought treatments led to raise antioxidants production in plant leaves at the period of 40 days from sowing to hinder the hazard effect of ROS, which were produced due to water deficit stress, while soil conditioners and foliar applications led to a decline of the maize plant's self-production from antioxidants.On the contrary, plants grown without studied substances cannot continue producing antioxidants under drought treatments in the advanced stage of growth (70 days from sowing). | ||||
