• Evapotranspiration (ET)

•  Irrigation of greenhouse crops in Egypt

• Water requirements of Egyptian greenhouse crops

•  Determination of crop coefficient values for Egyptian greenhouse crops

•  Factor contributing to relatively low ETc values in greenhouse

·         Use the soil mulch

·         Used shading above the greenhouse roof

     Used cooling techniques
