To compare the effect of different stubble treatments on crop establishment, growth, grain yield and quality over a three year timeframe.
Overall, early growth was a function of a number of constraints. In the fully retained stubble plots plant establishment was poor due to large straw windrows creating major problems at sowing and mice damage. In surface stubble treatments lower soil temperatures and higher populations of vulpia resulted in reduced plant vigour. Where stubble was fully retained this effect was less than when most stubble was removed through cutting and baling.
