Data from a fabricated experiment investigating the effects of Nitrogen application and seeding rate on grain production for a crop, conducted across 10 fictional sites in South Australia. The variables are as follows:
Site
: The experiment site locations.Latitude
: Latitude for the site, recorded in decimal degrees Northing.Longitude
: Longitude for the site, in decimal degrees Easting.SowDate
: The date that the crops were sown.NitrogenDate
: The date that the Nitrogen treatments were applied.Rep
: Replicate number. (Each site has 3 replicates.)Variety
: The anonymised variety (10 levels).Nitrogen_kgNha
: The applied Nitrogen rate treatment, in kg N/ha.SeedRate_plantsm2
: The seeding rate, measured in target establishment plants/m2.Yield_Tha
: The measured grain yield for the plot in T/ha.
