Abstract

The Performance of a CENTER-PIVOT IRRIGATION system was evaluated. The system was located at station # 37, section 4 of Pars Agro- industry company in Moghan. The system irrigated 47.26 hectares of a loamy soil land, planted weed corn in 2000. The object of this study was to investigate application design problems of the system, in order to improve IRRIGATION water use efficiency. Evaluation factors: Potential Application Efficiency of Low Quarter (PELQ), Application Efficiencey of Low Quarter (AELQ) and Distribution Uniformity (DU), following FAO and ASCE standards, were calculated using field data analysis. Field data including soil moisture content before IRRIGATION and after 24-48 hrs., root depth rotating speed of the system and water distribution pattern were measured and recorded during the IRRIGATION season. To observe water distribution pattern, containers were set up on four radial rows under the system in a six-meter spacing.The averages of PELQ, AELQ and DU were found 38.00,37.07 and 49.01 percent, respectively. These values, according to the above mentioned standards, are considered- to be low, indicating that the performance of the system was far from ideal.Based. on the analysis of the results, recommendations were made as to adjustment of rotating speed, application frequencies, water supply in proportion to crop requirements etc. for improving application design of the system.
