THE USE OF METEOROLOGICAL DATA AND GEOGRAPHIC INFORMATION SYSTEMS (GIS) IN THE INTEGRATED MANAGEMENT OF SOIL AND WATER FOR SUSTAINABLE AGRICULTURE IN TOSHKA

Abstract

The present investigation was carried out at the experimental Farm, Water Studies and Research Complex (WSRC) Station, National Water Research Center, Toshka, Egypt during 2013/2014 and 2014/2015 seasons. Wheat crop was used in the current study to test the integrated management of water and agriculture as well as in an assessment of reference evapotranspiration (ET0) within the meteorological data by using computer programs. The transactions of different irrigation regimes (60, 80, 100 and 120%) was applied based on crop evapotranspiration (ETc) that was calculated by the amounts calculated daily (ETo), measured using penman-monteith method, where the irrigation process were carried out at 8 am. Results showed the comparison between Misr 1 and Misr 2 wheat cultivars in both seasons under the different irrigation treatments was not significant for all studied characters while there were significant differences among irrigation regimes (60, 80,100 and 120%) (ETc) as well as in terms of Super Absorbent Polymers (SAP) (hydrogel treatment) compared to null treatment. . The heighest wheat crop productivity was obtained when used (120% ETc treatment) coupled with adding Hydrogel as a (SAP
