This study was carried out to investigate the effects of T-P concentrations in irrigation water on the growth, yield, and grain quality of rice. It acquire fundamental knowledges to set up irrigation water quality standards. The pot experiment was conducted with 5 treatments using irrigation waters. It consisted of various total phosphorus concentrations(control, I, 2, 5, 10mg/L) and replicated four times with randomized block design. The results of this study showed that as T-P concentrations in irrigation water increases, plant height tended to increase. Dry weight of rice plant at T-P 10mg/L was significantly higher than the control. However, T-P in irrigation water did not affect plant height, tiller number, plant dry weight, yield, and quality of rice.
