To provide a prediction for the number of million bales of cotton that will be harvested during the fall of 2023, we need to consider the impact of drought and high temperatures on cotton yields. Generally, adverse weather conditions like drought can significantly reduce crop yields, while high temperatures can also stress plants and affect growth.
Given these factors, if the summer of 2023 experienced severe drought and high temperatures, it is likely that the cotton harvest would be on the lower end. Based on historical data and the expected conditions, a reasonable prediction might be between 2-4 million bales.
Thus, of the options provided, I would predict 2-4 million bales of cotton will be harvested in the fall of 2023.
