Objective of this research was to investigate the effect of fertigation setting point such as -5, -10, -20, and -30 §æ on the growth and fruit quality of sweet pepper (Capsicum annuum L.) in greenhouse culture. The net $CO_2$ assimilation and transpiration rate were the lowest in the treatment of -30§æ. The pH and EC in soil solution were not severly affected by irrigation setting point and no statistical differences were observed among treatments of irrigation setting point tested. The N content of above ground plant tissue was the lowest in the treatment of -30 §æ and those of K, Ca, and Mg were the highest in the treatment of -10 §æ. But that of P did not show statistical differences among treatments tested. As the fertigation setting point was getting low, the growth decreased at 60th day after planting, while there were no differences among treatments at 210th day after planting. The fruit quality except sugar contents did not show differences among treatments, but sugar contents was the highest in the treatment of -30 §æ with $8.0^{circ}$Brix. Above results indicated that fertigation setting point should be in the range from -10 §æ to -20 §æ to ensure good crop growth and fruit quality in sweet pepper production.
