Step 1: Understanding the Concept:
Forage crops (or fodder crops) are plants that are grown specifically to be consumed by livestock, such as cattle, goats, and sheep.
They can be consumed fresh through grazing, or preserved as hay (dried) or silage (fermented).
High-quality forage is essential for maximizing milk and meat production in animal husbandry.
Step 2: Detailed Explanation:
Let's classify the crops mentioned in the question:
1. Berseem (A): {Trifolium alexandrinum}, commonly known as Egyptian Clover. It is the most important leguminous forage crop of the winter (Rabi) season in India. It is often referred to as the "King of Fodders" because it is highly nutritious, palatable, and provides multiple cuttings. It is a definitive forage crop.
2. Safflower (B): {Carthamus tinctorius}. This is primarily an oilseed crop. While the oil-cake left after extraction can be used as animal feed, the crop itself is grown for its seeds (oil) and flowers (dyes). It is not categorized as a forage crop.
3. Lucerne (C): {Medicago sativa}, also known as Alfalfa. It is a perennial leguminous crop and is widely considered the "Queen of Forages". It is incredibly rich in protein and vitamins. It is a world-renowned forage crop.
4. Sunflower (D): {Helianthus annuus}. Like safflower, this is a major oilseed crop. It is cultivated for the high-quality edible oil in its seeds. It is not a primary forage crop.
Conclusion: Only Berseem (A) and Lucerne (C) are forage crops.
Step 3: Final Answer:
Based on the agricultural classification of crops, Berseem and Lucerne are the only forage crops in the list.
Therefore, the correct choice is option (B) A and C only.
