Abstract
Egypt is recently facing the challenge of limited water due to the increase in population and the limitation of water resources. Therefore, this means that researchers must investigate non-conventional water sources, for example, the use of greywater. Since quantities of water are consumed in the ablution process, and this water is less polluted, this research aims to collect ablution water and study its quality as reuse water in the irrigation of squash plants. Three treatments were carried out for irrigation: 1- Tap water (TP: control), 2- Greywater (GW), and 3- Magnetized greywater (MGW). To investigate how well these treatments worked, some measurements were made on squash plants and soil properties. The tenth (10th) and twentieth (20th) day following the agriculture produced the maximum chlorophyll a (Chl-a), chlorophyll b (Chl-b) and carotenoid (Car) levels as compared to control when plants were watered with MGW. Additionally, the activity of antioxidant enzymes is raised when GW is used, whereas it diminishes when MAW is used, compared to control on the 10th and 20th day after agriculture. The outcomes data demonstrated that MAW irrigation of squash plants produced the greatest NPK values. It is very promising for the reuse of GW in irrigation. Among different irrigation water used (TP, GW and MGW), MAW recorded the most significant values of soil chemical properties as well as seed germination. The data showed that the EC value of soil irrigated by MGW significantly decreased compared to the EC values of the soil before irrigation or soil irrigated by GW or TP.
