e0“applying deficit irrigation (375 m 3 ha −1 ) at the flowering stage of maize grown at medium density (M: 75000 plant ha −1 ) under the RFRH system (MIF) can improve soil water storage (0–200 cm) at the bell, filling and flowering stages”
e2“MIF also improved irrigation water use efficiency (IWUE) (9%) and irrigation water productivity (IWP) (46%) compared with no-irrigation under the RFRH system (MI 0 )”
