e0“At all sites, direct seeding led to lower below-ground biomass growth and seed cotton yields compared with conventional tillage in an early transition to conservation agriculture starting from degraded soils (2% to 25%).”

Other claims from this paper (11)
- Intervention effect Direct seeding lowered below-ground biomass growth relative to conventional tillage.
- Intervention effect Cotton yield under direct seeding was 12% lower than under tillage.
- Intervention effect Cotton yield under direct seeding was 15% lower than under strip tillage.
- Intervention effect At 45 days after emergence, direct-seeded cotton was 9% shorter than tilled cotton.
- Intervention effect At 90 days after emergence, direct-seeded cotton was 13% shorter than tilled cotton.
- Intervention effect At 45 days after emergence, direct-seeded cotton was 23% shorter than strip-tilled cotton.
- Intervention effect At 90 days after emergence, direct-seeded cotton was 6% shorter than strip-tilled cotton.
- Intervention effect Fertilizer effects on seed cotton yield varied by site and treatment and were marginal within tillage methods.
- Intervention effect Fertilizer regimes increased yield differences between conventional and no tillage.
- Recommendation The authors consider limited early yield penalties under conservation agriculture a reasonable trade-off.
- Recommendation The authors suggest strip tillage to start a transition without initial yield penalties.
