Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Seed metering mechanisms meter seeds from the hopper into the delivery seed tubes at a calibrated, uniform rate depending on seed shape and size.
Step 2: Detailed Explanation:
Standard seed metering mechanisms include:
1. Fluted Roller Mechanism: The standard mechanism used in tractor-drawn seed drills for cereal grains like wheat, barley, and oats. Rotating longitudinal flutes meter seeds continuously without mechanical grain damage.
2. Cup Feed Mechanism: Used in older British drills for variable seed sizes.
3. Cell Edge Drop Plate Feed: Used in precision planters for single-seed metering of row crops (maize, cotton, groundnut).
4. Brush Feed: Used for small horticultural and grass seeds.
Step 3: Final Answer:
Hence, the suitable metering mechanism for wheat seeds is Fluted roller, corresponding to option (D).
