Abstract
Drip irrigation is a system for supplying filtered water and sometimes fertilizer directly onto or into the soil. Clogging causes poor distribution along the lateral line, and it may take time before they are discovered, cleaned, or repaired, resulting in a poor distribution of plant watering along the lateral line. As a result, it is necessary to investigate the hydraulic performance of these systems to zero in on the most important influencing parameters. In this study, the irrigation systems produced and imported, which are frequently used by farmers in the Iraqi Governorate of Kerbala. The results obtained for systems of drip irrigation indicate when using dripper (1), the field uniformity ranged between 73.4% to 88%. The uniformity of absolute ranges between 73% and 86% and the design uniformity range between 70.8% and 85.2%. The uniformity coefficient of statistical (SU_c) was ranging between 73.4% and 88.6%. The coefficient of variation ( ) for the irrigation system was ranging between 0.26 and 0.11%. The efficiency of application ranged from 73.4% to 86.8%. When using dripper (2), the field uniformity obtained ranged from 84% to 95%, the uniformity of absolute ranged between 83% and 94%. The design uniformity ranged from 79.7% to 93%, and the uniformity coefficient of statistical (SU_c) was ranging between 86% and 95%. The coefficient of variation ( ) ranged from 0.13 to 0.05%, and the efficiency of application ranged between 82.5% and 94%.
