Application of magnetic field improves growth, yield and fruit quality of tomato irrigated alternatively by fresh and agricultural drainage water.

Although the North Delta region in Egypt is one of the most densely populated areas in the world, it suffers from a severe shortage of fresh water needed to irrigate crops. So usually farmers resort to the use of low-quality water, such as agricultural drainage water, which could pose a threat to the quality of crops and then human health. Two field experiments were carried out during two consecutive summer seasons of 2014 and 2015 aimed at delivering more information about the pros and cons of alternative irrigation for tomato using fresh and agricultural drainage water with or without applying of magnetic field.
