Summary Crops grown with flood irrigation on slowly draining clay soils are subject to periods of waterlogging during and after each irrigation. The aim of this experiment was to quantify crop responses to these short-term waterlogging events and to assess the modifying effect of different agronomic practices. Maize was grown in undisturbed (U) and repacked (R) profiles of clay loam soil encased in steel cylinders (0.75 m diameter × 1.4 m deep). Two levels of N (high (HN) 300 kg N ha−1, and low (LN) 150 kg N ha−1) were applied as a split dressing. Three periods of flooding (F) of 72, 72 and 48 h were imposed on half the treatments beginning on days 40, 54 and 68 respectively after sowing. The other irrigation regime (C) kept the profile well watered but avoided surface inundation.
