Bengal gram is considered as an inseparable other crop plant in the seed production field of the
Show Hint
- Green gram
- Cowpea
- Oat
- Lentil
The Correct Option is D
Solution and Explanation
"Inseparable other crop plants" are those cultivated plant species whose seeds are so similar to the main seed crop in size, shape, surface texture, and weight that they cannot be easily separated by standard commercial mechanical seed cleaning equipment.
Their presence in the seed field is highly restricted to maintain physical purity standards during certification.
Step 2: Detailed Explanation:
In agricultural seed production, seed crop standards list specific inseparable other crop plants for major crops:
- For Barley: Oats and Wheat are inseparable.
- For Wheat: Barley, Oats, and Gram (Bengal gram) are inseparable.
- For Lentil (Lens culinaris): Pea, Bengal gram (Cicer arietinum), and Lathyrus are designated as inseparable other crop plants.
Lentil and Bengal gram are both winter (Rabi) season pulse crops grown under highly overlapping environmental conditions.
Small-seeded Bengal gram can easily contaminate lentil crops.
Because their seed physical dimensions and specific gravity overlap, separating them using screens or gravity separators is extremely difficult.
Therefore, Bengal gram is considered an inseparable other crop plant in lentil seed production fields, requiring rigorous roguing during field inspections.
Options (A) and (B) (Green gram and Cowpea) are warm-season (Kharif) crops with entirely different growth habits and highly distinct seed characteristics, making them easy to separate.
Option (C) (Oat) is a winter cereal with elongated seeds that are easily separated from spherical pulse seeds.
Step 3: Final Answer:
Bengal gram is considered as an inseparable other crop plant in the seed production field of lentil.
Therefore, the correct option is (D).
