The given statement states that ploughing is done for. We need to identify the appropriate option that describes the next step or purpose after ploughing. Let's analyze each option:
A: Harvesting
- Harvesting is the process of gathering mature crops from the field.
- Harvesting is done after the crops have grown and matured.
- Ploughing is done before sowing seeds or planting crops, so it is not directly related to harvesting.
- Therefore, option A is not the correct answer.
B: Preparation
- Preparation refers to the activities done to make the land ready for planting or sowing seeds.
- Ploughing is an essential step in land preparation as it helps loosen the soil and remove weeds and debris.
- After ploughing, further preparation steps like leveling, furrowing, or adding fertilizers may be required before planting.
- Therefore, option B is the correct answer as it describes the next step after ploughing.
C: Weeding
- Weeding is the process of removing unwanted plants (weeds) from the field.
- While weeding is a necessary agricultural practice, it is not directly related to ploughing.
- Ploughing helps in weed control by burying the weed seeds deeper in the soil, reducing their germination.
- However, weeding is typically done after the crops have been planted, not immediately after ploughing.
- Therefore, option C is not the correct answer.
D: Irrigation
- Irrigation is the artificial application of water to the soil to ensure proper plant growth and development.
- While irrigation is an important step in agriculture, it is not directly related to ploughing.
- Ploughing is done to prepare the soil and create a suitable seedbed, but it does not involve the application of water.
- Therefore, option D is not the correct answer.
In conclusion, the correct answer is B: Preparation as it describes the next step after ploughing.
