Planting Effective Plots

Quality data can only be achieved through quality plots. Establishment of the plot is critical we need to be aware of the following things:

Pre plant preparation

• Stakes, forms, GPS unit, safety equip.
• Check plot seed inventory – do you have the hybrids you want
• Plan ahead– If possible plant the plot early in the season.

Successful Plot establishment

• Site is level and of one soil type
• Watch for dead furrows
• Identifications stakes – 2 per variety in the corn row
• Documentation – fully completed (includes soil type, tillage, previous crop etc.)
• GPS location or map to find site
• Correct planting depth
• Population – watch seed size and changes in population
• Leave documentation with dealer or NK rep.

In season Assessment

Monitor that the stakes are correct
Trim fronts or make a path to and along the front of the plot for easier access.


• Spring Vigour
• Flowering/pollination
• Pest pressure – insect/weed/disease
• Maturity – milk line or black layer

Harvest assessment

• Population
• Lodging
• Pest pressure – insect/weed/disease
• Stalk integrity – push test
• Moisture
• Test weight
• Yield

Remember using your plot information and information of other plots in the area and throughout North America as the best way to get the ‘right hybrid on the right field for the highest yield’.
