Why is grain sorghum beneficial in drier areas?

• A. It tastes better than corn
• B. It has higher protein than corn
• C. It can be grown in conditions where corn may not thrive
• D. It requires more water

Answer: (C)

In dry conditions, the plant’s ability to use water efficiently and still complete its growth cycle is what matters for choosing a grain for feed. Grain sorghum is notably drought-tolerant and can thrive with less water than corn, which makes it a reliable option in arid regions.

That’s why the best choice is the one about growing in conditions where corn may not thrive. Sorghum’s physiology—its efficient water use, heat tolerance, and deeper rooting—lets it produce grain when rainfall is limited, so it’s often more suitable for drier climates than corn. Taste or protein content aren’t the driving factors for this environmental suitability, and sorghum does not require more water; it generally needs less.
