To evaluate the climate adaptation, agronomic management, and rotational value of diverse oilseed crops in wheat-dominated semiarid cropping systems of the northern Great Plains.
Synthesized regional field research comparing cool-season oilseeds (canola, mustard, flax) and warm-season oilseeds (sunflower, safflower) across the northern United States and Canadian prairies.
Evaluated agronomic management practices, including early spring seeding, dormant seeding, and no-till planting systems for small-seeded crop establishment.
Canola, mustard, and flax show strong adaptation to cool, short-season environments, whereas sunflower and safflower require warmer, longer growing seasons.
No-till seeding systems improve seed-to-soil contact and conserve soil moisture, facilitating the establishment of small-seeded oilseeds in semiarid conditions.
Adjusting planting dates via dormant and early spring seeding broadens the geographical range and rotational utility of oilseed crops within cereal-based farming systems.
