e0“Maize ( Zea mays L.) in the early season in no‐till (NT), compared with conventional tillage (CT), has reduced dry matter due to cooler temperatures near the seed, in spite of increased plant P absorption caused by more effective mycorrhizae in the less‐disturbed soil”

Other claims from this paper (9)
- Intervention effect No-till and no-till hand-planting stimulated early-season P uptake and mycorrhizal colonization in maize.
- Intervention effect Shoot dry mass was reduced in the no-till and no-till hand-planting treatments compared with conventional tillage.
- Intervention effect At all P rates, maize yields under conventional tillage and rotary cultivator were similar.
- Intervention effect At all P rates, maize yields under no-till hand-planting and no-till were similar.
- Intervention effect Maize yields increased with increasing fertilization.
- Intervention effect At low soil P fertility, no-till and conventional tillage gave similar maize yields.
- Intervention effect At and above 50 kg P ha −1, maize yields under conventional tillage exceeded those under no-till by 1000 kg ha −1.
- Mechanism Increased plant P absorption under no-till was attributed to more effective mycorrhizae in the less-disturbed soil.
- Intervention effect Early-season responses to tillage treatments were the same at each fertilizer rate in maize.
