I have observed flows for furrow irrigation ranging from 0.3L/s to above 10 L/s per furrow for broadacre crops. The ideal flowrate is influenced by many factors including the field length. For example in Australia for cotton grown on heavy clay soil with a 1000m field length we commonly recommend a flowrate of 5 to 6 L/s per furrow (furrows on 2m spacing)
