Changes in Growth and Some Biochemical Parameters of Maize Plants Irrigated with Sewage Water

The purpose of this investigation was to study the effect of sewage water irrigation on the growth, photosynthetic pigments, sugars, proteins, total free amino acids, proline and the activity of antioxidant enzymes of maize plants. Results indicated that sewage-irrigated plants in most cases showed a significant increase in growth and all biochemical parameters than the control plants. This increase was generally higher in shoot than root. This study provides evidence for a beneficial effect of sewage water application for maize plants.
