Question Statement:
The seed metering mechanism most widely recommended and suitable for precision planting of single seeds of crops like cotton, maize, and groundnut is:
Options:
(A) Fluted roller mechanism
(B) Internal double run mechanism
(C) Horizontal or inclined cell plate mechanism
(D) Corrugated roller mechanism
Answer Key:
C
Step-by-Step Solution & Explanation
Inclined and horizontal cell plate / cup-feed mechanisms are precision metering devices designed to pick up and drop individual seeds (cotton, maize, groundnut) with minimal mechanical damage and uniform plant-to-plant spacing. Fluted rollers and internal double-run devices are used for continuous drilling of small grains (wheat, barley).
