Description

The total area planted to beets in Québec has been increasing in recent years. Over 650 hectares of beets were grown in 2011. Yet no fertilization chart had been developed specifically for this crop. The chart in use was not based on scientific trials and was a general chart for beets and radishes. Industry stakeholders estimated that the recommended nitrogen dose of 11 kg N/ha was not sufficient to cover the crops needs. Furthermore, there was no scientifically validated data on phosphorus doses to help extension agents manage the environmental constraints in the Agricultural Operations Regulation (AOR). Therefore it was important to conduct NPK fertilizer trials on this crop.

Objective(s)

  • Determine the nutrient needs of beets based on soil texture and phosphorus and potassium levels under Québec growing conditions.
  • Develop NPK fertilization charts tailored to Québec growing conditions. The knowledge acquired through this project will support the current expansion in beet farming. Applying lower doses than required prevents the crop from growing properly while applying too much fertilizer increases the cost per unit and the risk of nutrient flow into the environment. Proper fertilization therefore will make Québec producers more competitive while protecting the environment.
