Which of the following crops is considered a major specialty crop in western Canada?

Dry peas are considered a major specialty crop in western Canada due to the region's conducive climate and soil conditions for their growth. They are particularly valued in crop rotations for their ability to improve soil health and provide nitrogen, which benefits subsequent crops. The popularity of dry peas is not just due to their agricultural advantages but also their increasing demand in both domestic and international markets, making them an important economic contributor for rural farmers in western Canada.

In contrast, wheat is a staple grain crop rather than a specialty crop, while rice is not typically grown in western Canada due to climatic constraints. Corn, though it is widely cultivated in other regions of Canada, does not have the same level of significance or specialty status in western Canada as dry peas do.
