| Abstract | ||
| The effect of P and K on fruit yield and mineral content of Florida Peach trees irrigated with magnetized water which investigated in two successive seasons (2010 and 2011). This study was carried out at Sadat City zone in North Egypt between longitude 30°40' and 21.41"E and latitudes 30°18' and 41.16"N. Fertilizer rates were of 150, 225, 300 g P2O5/tree and 250, 500, 750 g K2O/tree, beside control treatment (without PK). Phosphorus was mixed with organic manure (25 kg/tree) and supplied in Mid-October, whereas K was applied in three equal doses in October, November and February of each season. Magnetic water irrigation and non-magnetic were used at previous rates of P and K fertilizers. The results indicated that the application of 225 g P2O5 and 500 g/ K2O/tree increased economic fruit yield and mineral content of leaves with a high availability of P and K in soil orchard. Also, a significant positive effect was obtained of magnetized water irrigation for all fertilization rates. So, the results in this study showed that the optimum fertilizer treatment (P2K2) achieved the highest fruit yield and plant mineral content as well as mineral content of the studied soil. Moreover, it could be using magnetized irrigation water as a technology, which may be one of the factors contributing to the increase in the nutrients availability for Florida peach trees grown in newly reclaimed soils conditions. | ||
