Livestock Production Management- ICAR JRF/SRF 2024

MCQ (Single Correct)

Which one of the following are secondary tillage implements?

(A) .Subsoiler

(B) .Cultivator

(C) .Disc harrow

(D) . Wetland plough

Choose the correct answer from the options given below:

(A), (B) and (D) only. (B) and (C) only. Correct (6), (C) and (0) (B) and (D) only.

Cultivator (B): A secondary tillage implement used for seedbed preparation, intercultural operations, pulverizing clods, and destroying weeds.
Disc harrow (C): A secondary tillage implement utilized after primary ploughing to pulverize soil clods, incorporate plant residues, and level the seedbed.
Subsoiler (A): A heavy primary tillage implement designed to shatter impervious subsoil hardpans at depths of 30–60 cm without turning the soil.
Wetland plough (D): A specialized primary tillage implement used for initial puddling and turning wet soil under flooded rice field conditions.
Conclusion: Only Cultivator (B) and Disc harrow (C) are secondary tillage implements. (Correct answer: Option 2)
