Question

Which of the following is primary function of seed broadcaster?

• A. Open the seed furrow to proper depth
• B. Meter and distribute seed over a given width of land
• C. Deposit the seed in the furrow in acceptable pattern
• D. Cover the seed and compact soil around it

Hint:

Seed drills perform all four seeding functions (opening, metering, placing, covering).
Broadcasters perform only one: metering and throwing (distributing) the seed over the surface.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Broadcasting is a method of seed distribution that involves scattering seed randomly across the field surface.

Step 3: Detailed Explanation:
Let us analyze the mechanical actions of a broadcaster:
1.

Furrow Opening: Broadcasters do not utilize furrow openers. This eliminates (A).
2.

Metering and Distribution: The machine meters seed from a hopper and flings it outward over a designated width using rotating impellers. This matches (B).
3.

Deposition in Furrows: Since no furrows are opened, seeds are not deposited in furrows. This eliminates (C).
4.

Seed Covering: Broadcasters simply drop seed on the soil surface; covering and compaction must be performed by a separate harrowing or rolling pass. This eliminates (D).
Thus, the primary function of a broadcaster is to meter and distribute seed across a width of land.

Step 4: Final Answer:
The correct option is 2, which corresponds to "Meter and distribute seed over a given width of land".
