Detailed Explanation:

✅ Cowpea is used as pulse (Lobia for consumption), fodder (high-protein livestock feed), and green manure (rapid nitrogen fixation).
✅ Green gram serves as pulse (Moong dal), fodder (plant residues post-harvest), and green manure (short-duration soil enrichment crop).
✅ Pigeon pea functions as pulse (Arhar/Tur), fodder (leaves and pods), and green manure (nitrogen enhancement in intercropping systems).

All three crops serve triple purposes.
