Increasing Forage Maize Energy Level

Nitrogen

02.1 Fig 22 Nitrogen Yield Protein. Forage Maize Sudan

Rates need to be high enough to maximize plant growth and also ensure good protein assimilation in both grain and silage crops.

However, too much nitrogen can encourage excessive leaf growth, increasing the proportion of leaf and stem to grain. As a result, the starch content of maize silage can be reduced and maize yields can also suffer.

Phosphorus

Fig 38 Phosphorus Quality. Forage Maize Pakistan and Sudan. Rebuilt

Uptake of phosphorus from the soil continues after the grains begin to develop and at maturity 70% of the phosphorus in the plant is in the grain. Here it has a direct effect on maize grain protein. At later stages of growth, phosphorus boosts the development of grain and accelerates crop maturity.

Potassium

Potassium nutrition increases crude protein content of forage maize. There is evidence that boron increases the starch content of forage maize, increasing forage maize energy.

Zinc 

Zinc is an essential component of enzymes involved in carbohydrate metabolism and protein production. Therefore, a low zinc supply reduces growth and starch content of maize.

There is evidence that boron increases the yield and starch content of forage maize. Foliar applications made at the V5 or V6 stage, when there is significant leaf cover, will improve yields in deficient crops.
