Berseem
Explanation
Crops are classified based on their economic utility into categories such as food crops, fodder crops, fiber crops, and oilseeds. Fodder crops are specifically cultivated to provide feed for livestock.
- Berseem is correct: Berseem (Trifolium alexandrinum), also known as Egyptian clover, is one of the most important winter (Rabi) fodder crops in India. It is highly nutritious, palatable, and succulent, making it a primary source of green fodder for cattle and buffaloes.
- Lentil is incorrect: Lentil (Lens culinaris) is a pulse crop cultivated primarily for human consumption as a source of protein.
- Castor is incorrect: Castor (Ricinus communis) is a non-edible oilseed crop. Its oil is used for industrial and medicinal purposes, not as livestock fodder.
- Pigeon pea is incorrect: Pigeon pea (Cajanus cajan), also known as Arhar or Tur, is a major pulse crop used for human food. While the plant residues may be used as fuel or low-grade forage, the primary cultivation purpose is grain production.
Key Takeaway: Berseem is a dedicated leguminous fodder crop, whereas Lentil and Pigeon pea are pulses, and Castor is an oilseed crop.
