Wed Jan 07 05:50:03 UTC 2026: # Green Manuring Faces Adoption Hurdles Despite Proven Benefits in Tamil Nadu

The Story:
A study released by the State Planning Commission in Tamil Nadu reveals that while green manuring is recognized as a sustainable agricultural practice with significant benefits, its wider adoption is hampered by challenges related to seed availability and distribution. The report, titled ‘Impact analysis of Green Manuring under the Chief Minister’s Mannuyir Kaathu Mannuyir Kaappom Scheme’ prepared by the M.S. Swaminathan Research Foundation (MSSRF), surveyed over 5,000 farmers and found strong support for green manuring. However, issues like climatic constraints, knowledge gaps, and economic dependence on subsidies hinder its widespread implementation.

The study highlights the positive impacts of green manuring, including improved soil water holding capacity, enhanced soil fertility, increased crop yields, and reduced chemical fertilizer use. Economic benefits, such as lower cultivation costs and increased income, were also reported. The report recommends focusing on local decentralized seed production, strengthening extension services, and institutionalizing soil health monitoring to ensure large-scale adoption and long-term impact.

Key Points:

  • The study was conducted by the M.S. Swaminathan Research Foundation (MSSRF), surveying 5,168 farmers across 34 districts.
  • 98% of surveyed farmers expressed willingness to recommend green manuring.
  • 99.7% of surveyed farmers sowed the seeds, while only 0.3% did not due to monsoon failure, poor seed quality, or late distribution.
  • 97% of respondents observed improved soil water holding capacity, 93% noted enhanced soil fertility, 94% experienced increased crop yields, and 88% reported reduced chemical fertiliser use.
  • An average yield increase of up to 15% per acre and income gains of ₹17,500 per acre were reported.
  • 49% of farmers in the south zone were unwilling to adopt green manuring without government support.
  • The report recommends local decentralized seed production and strengthened extension services for wider adoption.

Key Takeaways:

  • Green manuring offers significant agricultural benefits in Tamil Nadu, including improved soil health and increased crop yields.
  • Seed availability and timely distribution remain critical bottlenecks to wider adoption.
  • Economic incentives and educational support are essential for encouraging farmers to adopt green manuring practices.
  • Decentralized seed production and strengthened extension services are crucial for the long-term success of the scheme.
  • The findings emphasize the need for a multi-faceted approach to promote sustainable agricultural practices.

Impact Analysis:

The findings of this report have significant implications for agricultural policy in Tamil Nadu. By addressing the bottlenecks identified in the study, the state government can promote wider adoption of green manuring and improve the sustainability and resilience of its agricultural sector. Focusing on local seed production, enhancing extension services, and providing economic incentives can empower farmers and contribute to long-term food security and environmental sustainability. The integration of soil health monitoring with national schemes can further enhance the effectiveness of green manuring practices. This research is poised to inform future policy decisions and investments aimed at promoting sustainable agriculture in the region and beyond.
