Abstract

The purpose of this study was to investigate the effects of ponding depth treatment on water balance in paddy fields. Field experiment was performed in an experimental farm in Taegu, southern part of Korea during the rice growing season in 2001, 2002 and 2003. Experimental plots were three 8m x 80m rectangular plots. Three ponding depth treatments, very shallow, shallow, and deep were used. Daily values of water balance components were measured in the field.The irrigation amounts measured at the experimental plots showed that the very shallow and the shallow ponded plots required smaller amount than the deep ponded plot. The shallow ponded plot saved irrigation water about 17.7% compared with the traditional deep ponded plot in 2001. The very shallow ponded plot saved irrigation water about 25.7% compared with the traditional deep ponded plot in 2002, The shallow ponded plot saved irrigation water about 18% compared with the deep ponded plot in 2003.
