The results show that dripping irrigation system was more effective than Sprinkler system on increasing the studied growth indices and biochemical attributes as well as yield quantity and quality. The results also show the enhancing effect of different α-tocopherol treatments on growth indices, and yield quantity and quality of the sweet corn varieties via enhancing photosynthetic pigments, indole acetic acid, phenolics, carbohydrates constituents, free amino acids and proline contents. Moreover, the interaction between the two irrigation systems and different concentrations α-tocopherol showed that, dripping irrigation with 200 mg/L α-tocopherol was the most effective treatment on in...
