Other claims from this paper (12)
- Intervention effect Seed soaking in Cu EDTA increased wheat seed yield.
- Intervention effect Seed soaking significantly reduced plant emergence in most cases.
- Intervention effect Seed-soaked Cu EDTA produced smaller yield gains than foliar Cu EDTA.
- Intervention effect Seed-soaked Cu EDTA produced smaller yield gains than spring soil-applied Cu EDTA.
- Intervention effect Spring soil spray-broadcast Cu EDTA produced the highest yield among spring applications.
- Intervention effect Granular Cu-treated MAP fertilizer had no significant effect on wheat seed yield.
- Association Copper uptake by seed generally followed seed yield trends.
- Intervention effect Partial factor productivity was higher with combined N and Cu than N alone.
- Intervention effect Residual soil nitrate was 3.3 to 4 times higher without Cu than under Cu fertilization.
- Recommendation The authors recommend previous-autumn surface-broadcast granular Cu sulphate with spring incorporation to correct Cu deficiency.
- Recommendation The authors conclude that low-rate Cu EDTA seed soaking can prevent Cu deficiency and increase yield.
- Recommendation The authors conclude that combined Cu and N fertilization can minimize residual nitrate accumulation and downward movement.
