Data input

The model needs the following information:

  1. Basic set-up information (e.g. grower, field location, variety, planting and emergence dates) which are entered on the Potato Crop Management web-site.
  2. Weekly measurements of crop ground cover. These can be entered manually on the web-site or automatically using the CanopyCheck app which runs on iPhone and iPads. A downloadable app User Guide is available here.
  3. Crop yields (taken at about 50 days after crop emergence) are entered onto the web-site as either total or graded yields. More detailed information on crop sampling is available here.

Yield forecasts provided to users will contain graphics and tables outlining expected crop development. An example of the model output is available here data can also be downloaded in csv format.
