A study was undertaken in the greenhouse to assess the performance of three irrigation systems which included sprinkler, drip and ebb and flow irrigations. Hand irrigation was also included as the check. Based on results from cost analysis, drip irrigation was the most profitable method for poinsettia production. Sprinkler irrigation showed lower cost than drip irrigation, and lower in water use efficiency as well as high in bract damage. The highest material cost was found in ebb and flow irrigation. There was no significant difference observed in the effect on plant growth among irrigation systems.
