| The machine of pipes installation of subsurface drip irrigation systems was tested and studied at the Abu-Ghalib farms production (private farm), El-Giza Governorate, Egypt, in growing summer season 2017. The goal of this research was to study the technical and economical evaluation of the installation subsurface pipes for drip irrigation system by Manual method (M) as control, Semi-Mechanical method (SM), and Quad-Raw Machine method (QRM) using different lateral spacing. The QRM method of installation is powered by tractor, the SM method consists of three steps: firstly, the drill plow is drilled under the soil using the tractor, then the pipes are extended in the holes by the labors, and the M method of installation is by labors only for all steps for... |

| 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... |
