| Abstract | ||||
| The aim of this research is to evaluate hydraulic performance of prevailing chemical injection equipment used with pressurized irrigation systems including; (1) By-pass pressure differential tank, (2) With suction pipe of irrigation pump, (3) Separate electric centrifugal pump, and (4) Venturi, to help in selecting an appropriate chemical injector according to field and operating conditions.The mainresults in this study can be summarized in the following: *The average of injection rates were: 190, 380, 1000, and 1175 for venturi, by-pass differential tank, with suction pipe of irrigation pump, and separate electric centrifugal pump respectively, at pressure drop or irrigation pressure of 100 kPa. * The average uniformity of injection rate ranged from 94.8 to 99% during fertigation time for prevailing equipment under study . * Economical verification of the feasibility of using chemical injectorsis discussed according to different field conditions. | ||||
