Última Design a Combined Machine for Seedbed Preparation CIGR Journal Salama, dina Saber; Pibars, Sabreen KH; Abdelhay, Yossry B.; Tayel, mohamed Y.; Nasr, Gamal M.. Soil preparation is a very important part of the grain production process as it is necessary to maximize the possible yield. The mechanical soil preparation assists better water and air circulation and fertilizer dissolving in soils, which can increase the grain yield. The aim of this investigation was to design a new combined machine for seedbed preparation in one trip and assesses its effect on some soil physical properties and crop yield. Field experiments were carried out on clay loam, three diverse tillage methods were conducted under the same conditions of soil moisture content, operating speed and plowing depth. The tillage methods were: new combined (NCM), traditional method (TM) and no tillage method (NT). Results Clarified that the new combined...

Ano: 2018 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/4591 Validation of EGY-DRIP program Application in Determining the Optimum Lateral Length CIGR Journal Pibars, Sabreen KH; Imam, Hisham M.. In drip irrigation systems the lateral lines are the pipes on which the emitters are installed. The accurate design of drip irrigation laterals needs to determine the total energy losses that include the pipe friction losses along the lateral line and minor losses due to emitter connections. A friendly user interface computer application named EGY-DRIP had developed for drip irrigation system design. The program had written in Microsoft visual basic 2013 to carry out hydraulic calculations of drip irrigation sub-unit design. The hydraulic calculation based on inputs of water properties, quality, soil characteristics, reference evapotranspiration, crop factors, and irrigation system components (drippers, pipes, and fittings). The program supported with an... Tipo: Info:eu-repo/semantics/article Palavras-chave: Validation; Drip irrigation system; EGY-DRIP Program; Friction losses..
