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.
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.

Increasing corn yield
The aim of every grower is high corn yield, and there are a large number of agronomic factors that can influence this, many of which are within the grower's control, given climatic and soil conditions.
Improving corn quality
Corn has different quality standards depending on the use of the crop. Good crop nutrition will ensure high protein and energy levels of grain in the corn cob. It will also help to boost the quality of the ensiled leaf material in forage crops.
Role of Nutrients by Corn Growth Stage
Corn crops require the right nutrients, at the right time, to achieve the best results possible. Here you find an overview of the role of nutrients by corn growth stages.
