A Study On Development Of Intelligent Irrigation Systems For Melon Cultivation In Greenhouse

摘要

The price of melon varies with its quality. It is very difficult to control the quality of melon in various growing stages, because irrigation management in a green house influences the fruit quality. In this study, the intelligent irrigation systems were developed using the know-how extracted from an expert. Fuzzy control and On-off control for irrigation were examined. Changes in soil moisture content were predicted by Fuzzy control systems with various climate sensors. As the results, the performances in Fuzzy control and On-off control were respectively 52% and 40% water saving compared to the manual irrigation by an expert. The qualities of fruits by Fuzzy control and On-off control were almost the same results from the manual irrigation.
