| Abstract | ||
| This study was conducted in the lath house , Department of Horticulture / University of Baghdad , during the growing season of 2005-2006 to investigate the effects of the magnetized water in dissolving and absorption of mineral elements by detecting the contents of those elements in the leaves of one year old orange splings local cultivar budded on sour orange rootstocks.This experiment laid out using a split plot design. The treatments with magnetized and non magnetized water were the main plots while the foliar sprays with urea , Fe and Zn were the sub plots . Irrigation was done using magnetized and non magnetized water . Magnetization of water was carried out by using two Dipolar inagnetizcr connected in series with water pipe. The mineral elements were sprayed at three different times . Trisuperphosphate (20% P) and potassium sulphate (42% K) at one level (25 g/ plant) for all treatments.Irrigation with magnetized water significantly increased the leaves mineral content of orange splings by a ratios of (10.78 , 26.14 , 19.29 % ) for the elements (N+ , P+3, K+ % ) and (6.28 , 10.89 , 17.72 %) for the elements (Fe+2 , Zn+2 , S+2 %) respectively as compared with the control treatment.Foliar spray with nitrogen and second level of Fe ,Zn significantly causes a highest increments of their concentration in the level (13.4 , 34.36 , 69.3 %) respectively , also the foliar sprays significantly increased the P , S , K content in the leaves.The interaction between magnetized water and the spray with nitrogen and the second level of Fe and Zn significantly gave the highest increment in ions concentration of (N+ , P+3, K+3, Fe+2, Zn+2, S+2) in the leaves as compared with the control treatment. | ||
