Question

Which of the following is primary function of broadcaster?

(A) Open the seed furrow to proper depth

(B) Meter the seed

(C) Distribute seed over a given width of land

(D) Deposit the seed in the furrow in acceptable pattern

(E) Cover the seed and compact soil around it

Choose the correct answer from the options given below:

• A. (A), (B), (C), (D) and (E).
• B. (A), (B), (D) and (E) only.
• C. (A), (D) and (E) only.
• D. (B) and (C) only.

Hint:

Remember a broadcaster works only on the surface, it never opens or closes a furrow.

Answer 1

The Correct Option is D

Step 1: A broadcaster is a seeding device that scatters seed over the soil surface across a width of land, unlike a seed drill which places seed in furrows at a fixed depth.

Step 2: Since a broadcaster does not open any furrow, statement (A), opening the seed furrow to proper depth, is not something it does, that job belongs to furrow openers on a seed drill.

Step 3: A broadcaster does need to meter the seed, that is control how much seed is released, so statement (B) is a genuine function.

Step 4: After metering, its other essential job is to spread that seed uniformly across the working width of the machine, so statement (C), distributing seed over a given width of land, is also genuine.

Step 5: Since there is no furrow, there is nothing to deposit seed into a furrow (D), and no covering or compacting of soil around the seed (E), those belong to a seed drill's covering device and press wheel, not a broadcaster.

So only (B) and (C) are true primary functions of a broadcaster, option 4.
