Modern greenhouses, particularly those that recirculate their drainage solution, have numerous climate, crop, fertigation and salinity controllable system variables, so they need a computer controlled decision support system (DSS) for optimal operation. To meet this need, the GREENMAN greenhouse management DSS was developed (Bar-Yosef et al., 2004; Bar-Yosef and Klaering, 2006). It aimed to be generic for all C3 greenhouse crops and a wide range of climate, growth substrate and water quality conditions. It is designed to issue hourly greenhouse management recommendations, but it is suitable for tactical and strategic decision making as well.
