Which two soybean maturity groups are most commonly grown in Oklahoma?

1. IV and V

2. 00 and 0

3. II and III

4. VII and VIII

The correct answer is: IV and V

In Oklahoma, the soybean maturity groups that are most commonly grown are group IV and group V. These groups are well-suited for the climatic conditions and growing season of the region, which allows for optimal development and yield of soybeans. Group IV soybeans typically have a shorter growing season and are ideal for the northern parts of Oklahoma where the length of the growing season may be limited. They are planted early in the season and harvested before the onset of fall frost. On the other hand, group V soybeans, which have a slightly longer growing season compared to group IV, can be planted in various parts of Oklahoma and are favorable in areas where the growing season is longer, maximizing potential yield. The selection of these groups takes into account factors such as soil type, rainfall patterns, and temperature, which all affect soybean growth and development. This understanding of local agricultural practices and environmental conditions is essential for optimizing soybean production in Oklahoma.
