The combined increase in demand for food and scarcity of water
worldwide necessitates saving water and increasing its
productivity. This study determined varietal performance of four
paddy cultivars - TXD306, TXD220, TXD88 and SUPA in terms
of yield as influenced by four different ponding levels. The study
assessed the yield and water productivity for each ponding depth,
the differences in seepage and percolation as a result of
differences in hydrostatic pressure. Results showed no
significant difference in yield of varieties as a result of ponding
treatments. This implies that a lot of water can be saved for
other uses if the optimum ponding level, i.e., zero level is adopted.
