Title
Effect of zinc application strategies on maize grain yield and zinc concentration in mollisols

Other claims from this paper (6)
- Intervention effect Zinc fertilization increased maize grain yield (GY) in four of five sites.
- Intervention effect Zn application strategies did not affect maize grain Zn concentration, which ranged from 19.5 to 43.1 mg kg−1.
- Observation At all sites, grain Zn concentration in the control treatment was above the maize sufficiency threshold of 18 mg kg−1.
- Recommendation The maize grain Zn sufficiency threshold needs to be updated for current maize hybrids.
- Recommendation Soil-Zn and foliar-Zn are the more suitable application strategies for maize at very low soil Zn availability.
- Method / resource Grain Zn concentration of maize was predicted by a regression model on grain yield and soil Zn-DTPA, with R2 = 0.38.
