This study includes three sites across Alberta, in Lethbridge, Vegreville, and Donnelly. Each location has been prepared with randomized split plots, approx. 1.5 x 6m in size. In Lethbridge, the hemp is grown under irrigation while all of the trials in Vegreville and Donnelly are rainfed. Sites have been seeded into cereal, pulse, or forage stubble. Special attention was paid to ensure no trial was seeded into canola.
All of the plots across Alberta have been treated with no tillage, or very minimal tillage from disking to allow for proper seeding. None of the plots were limited in nutrients and provided with supplements to promote healthy growth. Plots were well maintained and kept free of known pests and disease.
