This experiment aimed to improve the infiltration and water holding capacity of red–brown earth irrigated by furrow.
• Cover cropping did not improve cotton yields in this experiment.
• High stubble loads from spraying out the cover crop after the cereals reached growth stage Z39 negatively affected established cotton plant numbers and consequently lint yield.
• Cover crops terminated at growth stage Z39 had no yield penalty, but stored more soil water than the fallow treatment.
