Topic: Major crops cropping patterns in various parts of the country.
Q5. Explain the major agronomic differences between conventional transplanted paddy and Direct-Seeded Rice cultivation. Assess their implications for water use and weed management. (10 M)
Difficulty Level: Medium
Reference: IE
Why the question
The growing challenge of balancing agricultural productivity with ecological sustainability, particularly in water-stressed states like Punjab where rice cultivation practices are undergoing major transformation.
Key Demand of the question
The question requires explaining the major agronomic differences between conventional transplanted paddy and Direct-Seeded Rice cultivation systems. It also demands assessment of their implications for water consumption and weed-management practices.
Structure of the Answer:
Introduction
Briefly mention the ecological stress caused by water-intensive paddy cultivation and the emergence of DSR as a climate-adaptive agricultural practice.
Body
- Agronomic differences between transplanted paddy and DSR: Explain differences in crop establishment, irrigation practices, labour requirement, puddling, mechanisation, and weed emergence conditions.
- Implications for water use and weed management: Mention the benefits of DSR in reducing groundwater extraction along with challenges such as increased weed pressure, herbicide dependence, and the need for integrated weed-management systems.
Conclusion
Conclude by stating that sustainable rice cultivation requires balancing water conservation goals with long-term soil health and ecological sustainability through scientific and integrated farming practices.
