Machinery and operational methodology
- Zero-Till Seed-cum-Fertilizer Drill: Equipped with inverted-T openers that cut narrow soil slits in stubble, placing seeds and fertilizer simultaneously at uniform depth.
- Happy Seeder and Super Seeder: Advanced tractor implements that manage standing and loose paddy straw simultaneously, cutting straw, sowing wheat, and depositing mulch on top in a single pass.
- Operation: Sowing occurs directly behind the combine harvester while the soil retains residual kharif moisture.
Agronomic and economic benefits
Zero tillage eliminates 4 to 6 rounds of preparatory ploughing, saving up to 70% to 80% on diesel and operational time. It advances wheat sowing by 7 to 10 days, helping the crop escape terminal heat stress in March. The retained surface mulch reduces soil evaporation, moderates canopy temperatures, and prevents crop residue burning.
Weed dynamics and soil health improvements
- Surface mulch suppresses weed seed germination, particularly little seed canary grass (Phalaris minor) in wheat.
- Preserves soil organic matter, minimizes soil erosion, and promotes earthworm activity in the root zone.
- Government provides substantial machinery subsidies for Happy Seeders and Super Seeders under the Crop Residue Management (CRM) scheme.

Common questions
How does zero tillage help prevent air pollution and stubble burning?
By enabling farmers to sow wheat directly into standing paddy residue with Happy Seeders and Super Seeders, eliminating the need to burn rice straw.
Does zero tillage reduce wheat yield compared to conventional tillage?
No. Field trials across ICAR institutes demonstrate that zero-tilled wheat delivers equal or higher grain yields due to timely sowing and better moisture retention.
Where can farmers apply for subsidies on zero-till machinery?
Through the central SMAM portal (agrimachinery.nic.in) and state crop residue management portals.
