Any high-yield production system for maize should also consider zinc fertilizer as a matter of course to target early development.
Can too much nitrogen hurt corn?
Under- and over-applying nitrogen fertilizer to corn crops often leads to adverse economic consequences for corn producers. Excess levels of nitrogen in nature also pose serious threats to environment.

How do you increase maize yield?
How to increase maize grain yield
- Nitrogen fuels growth and crop yield.
- Phosphate improves root growth and crop establishment.
- Potassium deficiency restricts grain yield and quality.
- Magnesium has a vital role in photosynthesis.
- Micronutrient deficiencies can affect grain yield.
Is urea fertilizer good for maize?
Maize height and dry matter production were depressed with increasing salinity levels. The application of composted manure and urea fertilizer enhanced plant growth and nutrient uptake compared with the non-treated control. Maize growth was better under urea fertilizer than under composted manure.
How do you apply fertilizer to corn?
The most common and recommended starter fertilizer placement is 2 inches to the side and 2 inches below the kernel at planting (2-by-2 band). Placed in this manner, the possibility of fertilizer injury to the seed is reduced (Figure 1).
