Which of the following is grown as a winter annual crop in Oklahoma?

1. Corn

2. Soybean

3. Canola

4. Sesame

The correct answer is: Canola

Canola is grown as a winter annual crop in Oklahoma due to its ability to thrive in cooler temperatures and its growth cycle which allows it to be seeded in late summer or early fall and harvested in late spring or early summer. This crop is well-suited to the region's climate and can take advantage of the winter moisture, which helps in establishing its growth. In contrast, corn and soybean are typically grown as summer annual crops in Oklahoma, as they require warmer conditions for optimal growth and are usually planted in the spring. Sesame, while it can be grown in Oklahoma, is also primarily a warm-season crop and better suited for planting in late spring to summer, not as a winter annual. Therefore, canola stands out as the suitable choice for a winter annual crop in this context.
