Effective moisture conservation method for heavy soil under drip irrigation CIGR Journal
Mostafa, Harby M. S..
Abstract: Drip irrigation is one of the most efficient systems in delivering water to the plant root zone but it still allows relatively high evaporation from the saturated zone that develops under emitters especially in clay soils of low infiltration rates.  Initial lateral water movement may take a long time in such soils thus exposing surface water to high evaporation.  The vertical columns method induces water infiltration keeping the actual water surface deeper in the soil profile.  The objective of this research is to compare between the effect of vertical compost and sand columns on the distribution of water in the root zone and the potential for water saving in clay soil.  A field experiment was conducted and the results indicated that the vertical...

Performance of supplementary irrigation systems for corn silage in the sub-humid areas CIGR Journal
Mostafa, Harby M. S.; Derbala, Asaad.
In the humid and sub-humid areas, agricultural production is largely rain fed and this needs to be urgently supplemented by irrigation practice if the country is to meet its food demand.  A two years study was carried out at the experimental site of the Institute of Agricultural Technology and Biosystems Engineering, Johan Heinrich von Thünen Institute (vTI), Braunschweig, Germany to compare performance of maize crop for silage production using three different irrigation systems; rain fed, drip and rain-gun sprinkler.  Growth parameters such as plant height, stem diameter were measured.  The total yields of silage were obtained for all treatments at the harvesting.  The experimental results reveal that total yields obtained from different treatments were...
