With reference to the circumstances in Indian agriculture, the concept of “Conservation Agriculture” assumes significance. Which of the following fall under the Conservation Agriculture?

1. Avoiding the monoculture practices

2. Adopting minimum tillage

3. Avoiding the cultivation of plantation crops

4. Using crop residues to cover soil surface

5. Adopting spatial and temporal crop sequencing/crop rotations

Select the correct answer using the code given below:

The correct answer is 2, 4 and 5 (Adopting minimum tillage, Using crop residues to cover soil surface, and Adopting spatial and temporal crop sequencing/crop rotations).

Understanding Conservation Agriculture (CA):

Conservation Agriculture is a sustainable farming system based on three core principles linked together to conserve soil, water, and biological resources while ensuring profitable crop production:

1. Minimum Soil Disturbance (Minimum Tillage):
Practicing zero or minimum tillage minimizes soil erosion, preserves soil organic matter, and maintains the natural structure of the soil. (Statement 2 is correct)

2. Permanent Organic Soil Cover (Surface Residue Management):
Using crop residues, cover crops, or mulches to cover the soil surface protects the soil from wind and rain erosion, reduces water evaporation, and enhances biological activity. (Statement 4 is correct)

3. Diversified Crop Rotations (Spatial and Temporal Crop Sequencing):
Adopting diverse crop species in sequences (temporal) or intercropping combinations (spatial) helps prevent pest and disease buildup, enhances soil fertility, and optimizes nutrient usage. (Statement 5 is correct)

Analysis of Incorrect Statements:

• Statement 1 (Avoiding monoculture practices): While crop diversification is recommended, avoiding monoculture in itself is not defined as one of the fundamental pillars of Conservation Agriculture.

• Statement 3 (Avoiding the cultivation of plantation crops): Plantation crops (like tea, coffee, rubber, etc.) are actually perennial crops that provide permanent land cover and reduced soil disturbance, which aligns well with conservation goals. Avoiding them is not part of Conservation Agriculture.

Therefore, statements 2, 4, and 5 form the core components of Conservation Agriculture.
