Question

Which of the following is not a secondary tillage implement?

• A. Cultivators
• B. Harrow
• C. Rollers
• D. Meston plough

Answer 1

The correct option is D Meston plough

Secondary tillage is used to improve the seedbed by increased soil pulverization, to conserve moisture through the destruction of weeds, and to cut up crop residues. It is accomplished by use of various types of harrows, rollers, or pulverizers, and tools for mulching and fallowing.

Plough is a tool used for the initial cultivation of the soil for the preparation of the sowing. It is not a secondary tillage implement.
