Abstract
This study was carried out in the lath house , Department of Horticulturc,Univcrsity of Baghdad, during the growing seasons of 2005-2006 to investigate the effect of using magnetized water in irrigation , foliar sprays of urea , Fe , Zn on the vegetative and roots growth of orange saplings local cultivar budded in sour orange rootstock. The experiment was sctcd up using split plot design. The main plots were represented by magnetized and non magnetized waters , the sub plots were represented by the foliar sprays of urea , Fe , Zh. The saplings were irrigated with magnetized water and non magnetized water and foliar sprays of mineral elements were done at three different times. Irrigation with magnetized water significantly increased plant height, number of branches , stem diameter , length of root , number of root branches at a percentages of 39.30 , 19.70 , 50.00 , 21.47 and 39.31% , respectively, and also increased the total carbohydrates , leaf area , total chlorophyll , dry weight of vegetative parts , and dry weight of rooting system by a ratios of 23.92 , 18.71 , 12.99 , 17.39 , 8.77 % , respectively. Foliar sprays with mineral elements used in this study significantly influenced the vegetative and roots growth specially the foliar sprays with Urea by which a heights increment were happened in vegetative characters except total chlorophyll content and carbohydrate percentage where chlorophyll content was the height (3.60 mg /1) when Fe at (1.0 g /1) while the highest percentage of carbohydrate of 11.67 % were found when Zn at (1.13 g / I) was sprayed. The interaction effect of magnetized water and foliar sprays with urea . Fe and Zn significantly increased most parameter included in this study as compared with those treatments irrigated with non magnetized water and sprayed with the mineral elements used in this study.
