Other claims from this paper (12)
- Intervention effect At D1, no-tillage raised KTE 12.2% over conventional tillage.
- Intervention effect At D2, no-tillage raised maize yield 14.0% over conventional tillage.
- Intervention effect At D2, no-tillage raised KTE 13.9% over conventional tillage.
- Intervention effect At D1 in 2019, post-silking population DM accumulation was 11.0% higher with no-tillage than conventional tillage.
- Intervention effect At D2 in 2019, post-silking population DM accumulation was 16.9% higher with no-tillage.
- Association Maize yield correlated positively with ear number (r = 0.57***).
- Association Maize yield correlated positively with DMA (r = 0.64***).
- Association Potassium translocation correlated positively with KTE.
- Association K harvest index correlated positively with KTE.
- Intervention effect Under spring drought, long-term no-tillage significantly increased yield.
- Mechanism Authors attributed the no-tillage yield increase mainly to increased 1000-kernel weight.
- Mechanism Authors attributed increased K efficiency mainly to DM accumulation and distribution and K accumulation in grain.
