The venturi injector has been used widely in different sizes of irrigation system as one of the main fertilization devices. The venturi injector plays great roles in the quality of crop production especially, integration with irrigation system. In this paper, some of the major limitations associated with the operation of the venturi injector has been highlighted. These major difficulties found are unstable suction flow, backflow, and critical cavitation. These limitations affect the hydraulic performance of venturi injector by reducing the efficiency or total working performance. The future work suggestions for further upcoming research concentration were presented for improvement of agriculture field. | Review of venturi injector application technology for efficient fertigation in irrigation system
