Effect of Magnetic and Guality of Irrigation Water in Growth and Yield Parameters for Barley Crop (Hordium vulgare L.)

Abstract

Field experiments were conducted at the Research Station College of Agriculture,University of Basrah at Garmat Ali district. The experiments were carried outduring the winter season 2012-2013 in clay loam soil. The purpose of the research is tostudy the effect of water magnetization and the quality of irrigation water in growth andyield parameters for barley crop (Hordium vulgare L.) during the plant growth stages(the beginning of the branching and the beginning of flowering and after harvesting) .The experiments treatments Included magnetization of irrigation water, non-magnetizedwater (M0) and water magnetized (M1). The irrigation water quality treatment includedfive types of water namely, tap water (TW) , River water (RW), wastewater (WW),treated sewage water passed through sandy filter (WWT) and mixed water (MW) (50% RW + 50% WWT ).The experiments were conducted using factorial experimentsaccording to randomized complete block design is (RCBD). The irrigation water wasadded on the basis of the shortfall in the level of water of the evaporation basin installedin the field. The amount of water added was 100% of the amount vaporized water plus20% as leaching requirements. The results showed that :The plant height ,the dry weightof the roots and the grain yield per area increased significantly while the dry weight ofvegetative parts increased insignificantly with magnetized water compared with nonmagnetizedwater. The effect of the water quality treatments on growth parameters takenthe following order WW >TW >WWT >MW >RW.
