Other claims from this paper (19)
- Observation Corn grain yields ranged from 1.83 to 7.04 t/ha across applied potash fertilization levels.
- Observation Grain yields among corn hybrids ranged from 4.35 t/ha (Bc 66-61) to 5.31 t/ha (OsSK 407).
- Association Hybrid and K fertilization considerably influenced plant density realization.
- Observation Ear-leaf zinc at silking was low, at 23.2 mg Zn kg-1.
- Observation Ear-leaf manganese at silking was low, at 15.7 mg Mn kg-1.
- Observation Ear-leaf iron at silking was low, at 130 mg Fe kg-1.
- Observation Ear-leaf Zn ranged from 18.9 to 26.5 mg among hybrids, a significant effect of inheritance.
- Observation Ear-leaf Mn ranged from 14.2 to 17.2 mg among hybrids, a significant effect of inheritance.
- Observation Ear-leaf Fe ranged from 120 to 142 mg/kg among hybrids, a significant effect of inheritance.
- Intervention effect Ear-leaf Mn and Fe concentrations decreased under potash fertilization.
- Intervention effect Ear-leaf Zn increased under potash fertilization.
- Intervention effect Plant K status improved under potash fertilization, reaching 1.18% K.
- Intervention effect Plant Mg status was reported as improved under potash fertilization, at 0.47% Mg.
- Association Ear-leaf K status differences between OsSK377 and Bc66-61 may be linked to their grain yield differences.
- Intervention effect Corn grain yields were 75% lower under soil stress from K deficiency and Mg oversupply.
- Observation Soil test showed low exchangeable K.
- Observation Soil test showed high exchangeable Mg.
- Observation Soil test showed low Zn, Mn and Fe.
- Recommendation Increased K fertilization and more tolerant hybrids are recommended for corn production improvement on these problem soils.
