Abstract

A field experiment was conducted in Dhi-Qar Governorate, Al-Gharaf district, Al-Salem area adjacent to the Al-Gharaf river at longitude 31 ° 17?55 ? N and width 46 ° 14?30 ? E. This study was conducted in the autumn season of 2018 in clay-texture soil, to evaluate some of the drip irrigation system design parameters in the hydraulic properties of system, soil characteristics, growth, and yield of corn (Zea mays L.), and the economic feasibility of each system, emitters discharge treatments  (2, 4, 6 and 8 L.hr-1), the distance between the emitter treatments were 20, 30 and 40 cm, and the lengths of field pipes were 10, 15 and 20 m. The main results showed emitters discharge exceeded 8 L.hr-1 by 0.747 m.day-1, whereas it was 0.612, 0.512 and 0.348 m.day-1 for the treatments 6, 4 and 2 L.hr-1 respectively at the beginning of the growing season, while at the end of the season, the values were 0.907, 0.701, 0.589 and 0.461 m.day-1 for 8, 6, 4 and 2 L.hr-1. The distance 20 cm between emitters was significantly increasing in the hydraulic conductivity values by 11.92%, 32.98% compared with the 30 and 40 cm treatments, respectively, which amounted to 0.629 m.day-1. at the end of the season the values were 0.769, 0.669 and 0.539 m.day-1 for 20, 30 and 40 cm treatments respectively, while the treatment of field length of 10 m recorded the highest values at the beginning of the season by 0.661 the lowest values were 0.571 and 0.433 m.day-1 respectively, with a decline of 13.61%, 34.49% compared to the treatment of 10 m. At the end of the growing season, the values were 0.769, 0.678 and 0.547 m.day-1 for transactions 10, 15 and 20 m, respectively.
