| Abstract | ||
| Afield experiment was carried out during the winter seasons of 2008-2009 and 2009-2010 at the farm of Department of Field Crop Sciences, College of Agriculture-University of Baghdad, to evaluate the response of wheat (Triticum aestivum L) yield to irrigation with magnetized water and levels of fertilizers. A randomized complete block design by split plot arrangement was used with three replications. The main plots included four levels of magnetic water strength 0, 500, 1000 and 2000 GS, while the subplots included four levels of fertilizer 0, 1/2, 2/3 and 1F from the recommended level. The results showed that no significant effect of magnetized irrigation water on all yield characteristics studied was found in both seasons, although noticeable increasing was observed in some characteristics, such as number of spikes, number of grain in spike and biological yield in both seasons. However the levels of fertilizer significantly affected most yield characteristics of wheat in both seasons, and the recommended fertilizer level of 1 F caused greater effect on number of spikes 317.07 spike.m-2, number of grains in spike 61.95 grain.spike-¹, grain yield 6.20 t.ha-¹, biological yield 16.78 t.ha-¹, harvest index 37.03%, in first season, and number of spikes 318.55 spike.m-2, number of grain.spike-¹ 62.47 grain.spike-¹, grain yield 6.03 t.ha-¹, biological yield 15.65 t.ha-¹, harvest index 38.49% at second season as compared with others fertilizer levels. It was concluded that there was no significant responses of bread wheat cultivar IPA 99 to magnetized irrigation water. Irrigation with magnetized water did not lead to reduction in the fertilizer level usually applied to bread wheat. We recommend further studies to determine the response of other varieties of wheat and plant species to different magnetic irrigation water, and using other types of magnetic field and the forces are different, as the plant response to this technology vary according to species, plant species, types of forces and the magnetic field. | ||
