From UPSC perspective, the following things are important :
Prelims level: Direct Seeding of Rice (DSR)
Mains level: Read the attached story
Central Idea
- The ongoing southwest monsoon season in India has registered a deficiency of 37.2% in rainfall.
- Weak monsoon affects paddy cultivation, a water-intensive crop.
- This article explores the Direct Seeding of Rice (DSR) as a water-saving alternative to traditional transplanting methods in the context of deficient rainfall.
Understanding Direct Seeding of Rice (DSR)
- DSR is the method of directly sowing paddy in the field without nursery preparation, puddling, or flooding.
- Traditional transplanting methods use flooded fields to suppress weed growth and provide oxygen to the roots.
- DSR replaces water with chemical herbicides for weed control.
- DSR offers potential water savings and reduces irrigation dependency during early crop stages.
DSR Technique and Water Savings
- Field Preparation: Ploughing, laser levelling, and soil compaction to retain moisture.
- Sowing: Using DSR machines for direct sowing in the field.
- Weed Control: Application of pre-emergent herbicides to suppress weed germination.
- Reduced Irrigation: First irrigation required 18-20 days after sowing, reducing water usage.
Benefits and Cost Savings
- Water Savings: DSR reduces the total number of irrigations compared to traditional methods.
- Labor Savings: DSR machines cover larger areas in less time, reducing labor requirements and costs.
- Herbicide Costs: Additional expenses for herbicides are offset by savings in labor costs.
Challenges and Adoption of DSR
- Subsidized Electricity: Availability of subsidized or free electricity for irrigation reduces incentives for DSR adoption.
- Machine Design: Limited access to well-designed and efficient DSR machines hampers widespread adoption.
- Proper Plant Spacing: Achieving optimal plant-to-plant distance is crucial for successful DSR.
- Policy Incentives: State governments offering financial incentives for DSR adoption, such as in Haryana and Punjab.
Environmental and Sustainability Benefits
- Conservation of Water Resources: DSR reduces water consumption and contributes to water conservation efforts.
- Reduced Carbon Footprint: DSR eliminates the need for flooding fields, reducing methane emissions.
- Soil Health and Erosion Prevention: DSR promotes soil health by minimizing soil disturbance and erosion risks.
Future Outlook
- Government Initiatives: Promoting DSR through subsidies, awareness campaigns, and support for efficient machine development.
- Research and Development: Continuous research to improve DSR techniques, herbicide efficiency, and machine design.
- Farmer Education and Training: Enhancing knowledge and capacity-building programs to encourage wider DSR adoption.
- Future Prospects: Increasing DSR adoption can contribute to sustainable agriculture and resilience against water scarcity.
Conclusion
- Direct Seeding of Rice (DSR) offers a viable water-saving alternative to traditional transplanting methods.
- Adoption of DSR can mitigate the impact of deficient rainfall and water scarcity.
- Development of efficient DSR machines, supportive policies, and continuous research are crucial for widespread adoption of this sustainable farming technique.
