  1. Terrace tillage

  2. Reduced tillage

  3. No tillage

  4. Both B and C

Show answer
Correct Option: D
Explanation:
Conservation tillage is a tillage system that creates a suitable soil environment for growing a crop and that conserves soil, water and energy resources mainly through the reduction in the intensity of tillage, and retention of plant residues. The most important advantage of conservation tillage systems is significantly less soil erosion due to wind and water.  No tillage farming is a way of growing crops or pasture from year to year without disturbing the soil through tillage. No tillage is an agricultural technique which increases the amount of water that infiltrates into the soil, the soil's retention of organic matter and its cycling of nutrients. Reduced tillage  is a practice of minimising soil disturbance and allowing crop residue or stubble to remain on the ground instead of being thrown away or incorporated into the soil. In terracing, wide steps are cut around the slopes of hills to prevent soil erosion. Since, both reduced and no tillage indulge in soil and water conservation, same as the conservation tillage
So, the correct answer is 'Both B and C'
