GENERAL NOTES FOR ALL CEREALS:

  • Estimate or measure the germination of your seed; this will be a high percentage figure for all good seed, i.e. >90%. Germination figures are available on request for all PGG Wrightson Grain (PGW Grain) cultivars.
  • The TGW is available on all seed supplied by PGW Grain; obtain the TGW for other seed.
  • The establishment percentage needs to be adjusted to allow for field conditions, including soil type, seed bed quality as well as slug and other pest issues.
  • Adjusting the target plant number downwards, below the recommended ranges, should be considered for paddocks with a history of high fertility and/or lodging problems and especially in areas where growth may continue all winter e.g. the Manawatu.
  • Adjusting the target plant number upwards, beyond the recommended range, should be considered for dry conditions, low fertility or grass weed competition. If this is a regular issue, a review of your grass weed control strategy is recommended.
  • Barley is generally more take-all tolerant than wheat as a second-year cereal, and although yields are usually lower than a first-year barley crop, the risk of take-all seriously affecting yield is lower than wheat.
  • An appropriate plant growth regulator (PGR) programme needs to be assessed for individual crops and will be influenced by sowing date, seed rate, nitrogen use, crop thickness and yield potential. Some spring crops, may not need a PGR programme, and as with any cultivar, do not apply if the crop is under any form of stress. Please contact your local PGW Representative for site specific recommendations.
