With reference to the circumstances in Indian agriculture, the concept of “Conservation Agriculture” assumes significance” Which of the following fall under the Conservation Agriculture?
- Avoiding the monoculture practices
- Adopting minimum tillage
- Avoiding the cultivation of plantation crops
- Using crop residues to cover soil surface
- Adopting spatial and temporal crop sequencing/crop rotations
Select the correct answer using the code given below:
A.1, 3 and 4
B.2, 3, 4 and 5
D.1, 2, 3 and 5
C.2, 4 and 5
Correct Answer: Option C
Conservation Agriculture (CA), as defined by the Food and Agricultural Organization (FAO), is a resource-saving agricultural approach that aims for acceptable profits, high and sustained production, and environmental conservation.
The three main principles of Conservation Agriculture are:
- Minimum tillage and soil disturbance.
- Permanent soil cover with crop residues and live mulches.
- Crop rotation and intercropping.
Based on these principles:
- Adopting minimum tillage is a key component of CA.
- Using crop residues to cover the soil surface is also a fundamental practice.
- Adopting spatial and temporal crop sequencing/crop rotations aligns with the principle of crop rotation.
- While avoiding monoculture is beneficial, it is incorporated within the broader principle of crop rotation and diversification.
- The cultivation of plantation crops is not directly related to the core principles of Conservation Agriculture. It depends on specific farming systems and environmental conditions.
Therefore, options 2, 4, and 5 are correct.
Hence, option c is the correct answer.
