Reducing Corn Cob Defects
Corn cob defects can be caused by nutrient deficiency. Any corn abnormality needs to be analysed before it can lead to severe corn yield losses.
Phosphorus
Phosphorus deficiency can cause the corn cob to be defective, by taking on a distorted, twisted appearance with poor grain set at the point of the cob.
Potassium
Potassium deficient plants, show cobs smaller in size and can have incomplete corn grain set at the tip end.
Optimum potassium versus potassium deficient
Boron
Boron deficient grain set are restricted, with the corn cob having many missing kernels and a few large grains.
Copper
Copper deficient corn grains are deformed, leading to loss of yield and grain quality.
