| Abstract | ||||
| The current investigation was carried out to evaluate the ground water quality of some wells in Toshka area comparing with the Nile water (Nasser Lake) as a control, during 2007-2008 season. Soil chemical properties; and soil productivity for wheat plants (Triticm aestivum L) Giza 168 were also observed. Data obtained from water samples of all wells show that, the pH values of irrigation water were in the normal range, the values of EC were ranged from 0.93 to 1.99 dSm-1, the values of total dissolved solid (TDS mgl-1) were ranged between 595.2 to 1273.6 mgl-1, and the cation values for water wells were found in the following order: Na > Ca > Mg than K. While anions were: Cl > SO4 more than HCO3. Meanwhile, the data obtained from soil samples show that, the soil texture was generally sandy loam, soil reaction is generally slightly to moderately alkaline, gypsum content were ranged from 0.80 to 6.43%, soil organic matter ranged between 0.14 to 0.93%, cation exchange capacity was ranged between 3.08 to 17.62 meq/100g soil, and the soluble cations are in the following order: Na > Ca > Mg than K., while soluble anions were Cl > SO4 more than HCO3. Finally, soils in Toshka area were very poor in there contents of available macro and micro nutrients; therefore, the productivity of wheat plants were recorded 10.75 ardab fad-1. Also, data revealed that the macro and micronutrients in wheat grains, straw and roots recorded lower values compared with the normal values. | ||||
