• Walk the land to ensure that the stand is even, standing (not lodging) and has no many gapsReap the cobs from a measured 20 sq. metres.
  • If the rows are at 90cm, then you should reap 22m row length, if the rows are 75cm, then measure 26.6m row length.
  • Shell the cobs, weigh the grain and determine the moisture content using a moisture meter.
  • Do this for three or four separate samples at widely separate points and determine the average.
  • Use the calculator below to calculate yield average estimate corrected to 1 ha and to 12.5% Moisture Content
