Laboratory study was conducted to examine whether there is any beneficial effect of magnetically treated water on its quality and seedling emergence in sandculture. Water of various types like tap water, saline water, canal water and sewerage water was applied. Results revealed that the application of magnetized water promoted the germination rate of maize seeds, regardless of magnetic strength or flow rate. Seeds irrigated with magnetized water grew faster, higher and heavier than the untreated water and a significant effect appear with magnetized sewerage water. On the other hand, there was negligible effect of magnetically treated water on quality parameters like EC, pH, and SAR. The results are presented in this book that certainly enhance learning among researcher, scientists and students and helps planning research studies The authors appreciate the efforts of Barthlemy Chaton and his team in facilitating during book finalization and highly acknowledge publishing of this book by LAMBERT Publishing House Ltd., for technical knowledge sharing internationally.
