| Abstract | ||
| The experiment was conducted in a field of the College of Agriculture/University of Baghdad in 2013 to evaluate the effect of tractor speed and irrigation tubes installation system on some performance indicators for combine implement designed and manufactured locally used for tillage and installation of irrigation tubes with Massey Ferguson MF (650) 140 hp as a machine unit . Three levels of tractor speeds included 4.50, 5.50 and 6.50 km/m which represented main plots and two levels of irrigation installation Tubes systems included subsurface installation system and surface installation system(drip irrigation)represented sub plot’s study in this experiment included: Slippage percentage practical productivity, field efficiency and fuel consumption were measured in this study.Split plot design under randomized complete block design with three replications were used in this study . The results were as follow:the combination between practical speed 4.50km/h and surface installation system (drip irrigation) was superior in getting less slippage percentage 6.36%. The interaction between practical speed 6.50 km/h and surface installation system (drip irrigation) was superior in getting less rate of fuel consumption , highest practical productivity 1.29 ha/hr, field efficiency 81.90. We recommend to used combine implement Used for Tillage and Subsurface Irrigation Tubes Instillation. | ||
