Abstract

  • While it is logistically feasible to grow and harvest two short-season maize crops during the dry season in the West Kimberley, growing a single crop with high yield potential is a more efficient use of machinery, labour and inputs.
  • Total biomass yield from a double cropping trial east of Broome generated 20.8t/ha dry matter and 59.7t/ha of silage over a seven-month period but this did not exceed the yield achieved from growing a single crop with a longer-season phenology and best practice agronomy.
  • Plant population density was highly correlated with yield, underscoring the importance of achieving the target plant population at establishment of 60,000 plants/ha.
