Cranberries are a primary crop for which of the following states?

Cranberries are primarily associated with Wisconsin, which is known for its substantial production of this fruit. The state provides the ideal growing conditions, including the necessary climate, soil type, and water availability, which are crucial for cranberry cultivation. Wisconsin accounts for a significant portion of the cranberry harvest in the United States, often leading the country in production levels.

The other states listed—Nebraska, Missouri, and Iowa—do not have the same level of cranberry farming. While they may grow various crops, they are not recognized for cranberry production, making Wisconsin the standout choice for this particular question.
