The aim of this experiment was to determine:
• an experimental methodology for assessing the waterlogging tolerance of irrigated wheat
varieties
• whether there is sufficient variability in the tolerance of current wheat varieties to justify further
experiments to identify lines best suited to irrigation on waterlogging-prone soils.
• Measuring redox potential and soil water potential helps to explain crop responses to waterlogging
in different soils.
• Current varieties vary in their response to irrigation and waterlogging on heavy, sodic clays. As these soils occupy 40–60% of some irrigation districts, variety experiments on them are needed so lines better suited to irrigation on heavy, sodic clays can be selected.

DAP (di-ammonium phosphate) at 125 kg/ha was drilled with the seed. Both experiments were top-dressed with 250 kg/ha urea in split applications, with the first on 20 July at Jerilderie. |
