| Abstract | ||||
| This applied experiment was conducted at private Farm (160 feddan), sustained of soil and water salinity, at Km80 of Cairo-Alexandria desert road (the green wealth farms). Four electromagnetic devise (6 inch) set up on the main ground irrigation sources. One well for each agriculture sector Apricot, Peach, Flame-seedless grape and Thompson seedless grape sectors. These sectors has been irrigated by magnetic treated water (MTW), beginning of December2013, through a drip system. The results indicated that MTW has led to non-significant decrease of water salinity (only from 2.18-3.31 to 2.14- 3.12 dSm-1), pH (from 8.2- 8.3 to 8.25-8.15), SAR (from 6.4-7.7% to 5.6-6.0) and hypothetical NaCl (from 57.37 – 60.53% to 53.31- 58.15%) Concerning the effect of MTW on soil chemical properties, the data showed that soil salinity was decreased after using MTW compared with the normal water. Soil salinity was decrease from 4.88- 6.15 dSm-1to 2.73-4.15dSm-1 and 1.45-2.58 dSm-1 after one month and eight ones of the magnetic treatment, respectively. Besides, pH values were reduced from 8.2-8.3 to 7.9-8.05 before and after magnetic treatment respectively. As well as the hypothetical NaCl and MgCl2 were diminished from 21.5 meq/L and 8.0 meq/L to 6.3 and 3.0 meq/L through eight months from the treatment. It is worth mentioning that the magnetic irrigation had good effects the availability of NPK and micronutrients (Fe, Zn, Cu and Mn) all during fertilization season, entail the observed increasing on the yield of fruits. Thus, the results indicated that the main beneficial of using MTW were in improving yield for Apricot, Peach, Flame-seedless grape and Thompson seedless grape to 40.0, 29.0 23.0 and 19.0 % respectively. Also, raising the efficiency of water productivity till ranged to 40.2, 29.2, 28.0 and 19.3 %, respectively. | ||||
