ترجمة الملخص

The presentstudy aims to determine the efficiency of some organic acidsas Acetic acid, Oxalic acid, and Citric acid inpreventionof clogging phenomenon in emitters of drip irrigation systems. Three different kinds of emitters (EM1, EM2, EM3) were tested using saline well water containing accumulated gypsum and calcium carbonate. The accumulation of these salts that occurred at the nozzle and internal passage of emitter is increased by increasing of surrounding temperature. Two types of experiments were carried out in the present study. The first one is an indoor laboratory test, but the second is an outdoor field one. In the laboratory test, the solution and precipitation of gypsum and calcium carbonate were done, in addition to measuring of hydrogen number (pH) and electric conductivity (EC). The results showed that a concentration of 15 meq/l of citric acid was enough to dissolve these salts, on the other hand, the acetic and oxalic acids had a negative effect on solution. However, these organic acids didn’t increase the values of EC more than 3 millimho/cm. The field test was conducted on a basic soil, medium content of organic material. However, the last three acids were added to the irrigating water using a chemical fertilizer to determine the efficiency of each acid on the three tested kinds of emitters. The average discharge of emitters (q) and average pressure of laterals (H) were measured many times during the irrigation period 300 h. However, the total operating time of the tested irrigation network was 1200 h at the end of fourth year. The results showed that the third emitter kind (EM3) revealed reduction in emitters clogging better than other two kinds (EM1 and EM2) .Asthesecond emitter kind (EM2) revealed slightly better results than the first kind (EM1).A hydraulic study was also carried out in the present study. The values of emitter discharge coefficient (kl); emitter exponent (x); uniformity coefficient (Uc); The coefficient of variation of emitter’s performance along the lateral(Vf); and clogging percent (Pclog), were calculated for all emitter kinds. The results showed a good agreement between the indoor (laboratory) and outdoor (field) results.
