Step 1: Understanding the Concept:
Millets are a diverse group of small-seeded grasses widely grown around the world as cereal crops or grains for fodder and human food.
They are highly resilient to harsh environments and drought.
Step 2: Detailed Explanation:
Sorghum (Sorghum bicolor), commonly known as Jowar in India, is widely recognized as the "King of Millets."
Sorghum holds this title due to its dominant production volume, extensive geographical distribution, and high nutritional value.
It ranks as the fifth most important cereal crop globally in terms of production and acreage, following wheat, rice, maize, and barley.
Sorghum possesses excellent photosynthetic efficiency as a \( \text{C}_4 \) plant and exhibits high drought tolerance due to its deep root system and xerophytic leaf adaptations.
It serves as a dual-purpose crop, providing grain for human consumption and highly valuable nutritious fodder for livestock.
In nutritional terms, it is gluten-free, rich in dietary fiber, protein, and essential micronutrients like iron and phosphorus.
While Pearl millet (Bajra) is also highly significant, Sorghum's overall agricultural scale and versatility earn it the designation of the "King of Millets" in standard agronomic classification.
Step 3: Final Answer:
Sorghum is known as the King of Millets.
