an experiment was carried out in a private orchard located at Wadi El-Natroon district, El-Beheira Governorate, Egypt, during two successive seasons of 2014 and 2015. The aim was to test the influence of magnetizing irrigation water, bio-fertilizer inoculation [Effective Microorganisms (EM) – Plant Growth Promoting Rhizobacteria (PGPR) – Phosphorine (Bacillus megaterium)] and some soil amendments (agriculture sulphur – gypsummagnetic iron oxide) on yield and fruit nutrients content of Manfalouty pomegranate. Generally, the analysis of variance proved that, average of fruit weight (gm) and total yield (Kg/tree) were positively affected by magnetic water treatments than all other non-magnetic ones and the control. It can be seen that, in the 1st season magnetic water + PGPR gave the highest average of fruit weight (341.68 gm.) whereas, in the 2nd season the same previously mentioned treatment and magnetic water + gypsum recorded the highest values (325.00 and 326.00 gm). Magnetic water produced the maximum fruit yield (10.60 and 20.78 kg/tree) when supplemented with PGPR. All magnetic water treatments (especially when inoculated with PGPR or EM) caused more effective increasing of fruit yield compared with non-magnetic treatments and the control. As for fruit nutrients content (N, P, K, Mg, Ca, Fe, Cu, Zn and Mn), all magnetic treatments surpassed the other non-magnetic treatments and the control. However, fruit sodium content took the other way around whereas; the control and non-magnetic treatments led to marked increases in both parameters. |
