How to Increase Maize Yield Potential


Maize is one of the world’s major crops, it is the main source of food and agricultural income for farmers.

While the weather is often the most important factor in determining Maize yields, farmers can make several management decisions to help put the crop in optimal conditions and boost yield potential.


Field Improvement

Improve drainage system

Increase water retention

Avoiding soil compaction

Clean up field residue

Variety Selection

Selecting varieties that are suitable for the local environment can greatly increase yield potential.

Crop Rotation

Crop rotation as a method to increase the yield potential of subsequent maize crops, adding a crop to a year's rotation can lead to higher yield potential

Fertilizer Management

Maintaining proper soil fertility and soil pH can reduce the risk of low yields.

Starter fertilizers have been shown to promote early plant growth. And they are recommended at planting time in the following cases:

1. Planting occurs earlier than normal in cooler soils; 

2. Planting into reduced tillage systems with high residue cover; 

3. Planting is delayed due to lack of available P; 

4. Planting into a continuous Maize production system, especially in reduced tillage systems; 

5. Nutrients are not applied at adequate rates before planting.  

Ensuring that Maize can take up sufficient effective N during peak growth is key to reaching yield potential

Disease Management

Diseases attack Maize at the nutritional growth stage and are more susceptible to affecting yield.

Seedling diseases can reduce stand size and thus reduce the number of plants on the cob. Foliar diseases can reduce photosynthetic capacity, lower the number of grains per spike, and can lead to stem diseases that reduce the number of harvestable spikes.

High-quality seed treatments can help reduce seedling diseases.

To reduce the incidence of foliar fungal diseases, we will need to use fungicides.

Insect Management

Like Maize seedling diseases, seedling pests can reduce stand size and limit the number of plants that produce ears.

Insects feed on growing plants by limiting nutrient uptake by the root system, limiting the movement of resources in the stem, reducing the number of grains per ear by limiting pollination, and reducing the number of seeds after pollination.

Feeding on leaf tissue reduces photosynthetic capacity and decreases yield potential.

Insect feeding on the cob can also affect grain quality.

Weed Management

Weed control is essential to achieve optimal maize yields. The conditions and agricultural inputs necessary for high yield and quality also favor vigorous weed growth. Weeds compete for limited resources such as sunlight, water and nutrients and this is a major cause of reduced Maize yields.

Preventative Control

Preventative weed control refers to any control method that aims to prevent weeds from being established in a cultivated crop, a pasture, or a greenhouse. Examples of preventative weed control would be using certified weed free seed, only transporting hay that is weed free, making sure farm equipment is cleaned before moving from one location to another and screening irrigation water to prevent weed seeds from traveling along irrigation ditches.

Cultural Control

Cultural weed control refers to any technique that involves maintaining field conditions such that weeds are less likely to become established and/or increase in number. Examples of cultural weed control would be crop rotation, avoiding overgrazing of pastures or rangeland, using well-adapted competitive forage species, and maintaining good soil fertility.

Chemical Control

Chemical weed control refers to any technique that involves the application of a chemical (herbicide) to weeds or soil to control the germination or growth of the weed species. In economic terms, chemical control of weeds is a very large industry and there are scores of examples of chemical weed control products.

King’s Angel(Propisochlor + Mesotrione + Atrazine OD)


KING'S ANGELhas a broad spectrum of weed control and provides excellent yield protection in Maize.

One-step Solution

The unique and efficient formulation allows KING'S ANGEL to provide higher-level control of annual grasses and broadleaf weeds.

Fast Effect

KING'S ANGEL combines the power of 3 active ingredients in one formulation so it has excellent contact action.

  1. Propisochlor

    Propisochlor is an herbicide that is absorbed through the shoots of germinating plants

  2. Mesotrione

    Mesotrione is used as a selective herbicide that works by inhibiting HPPD, especially in maize.

  3. Atrazine

    Atrazine is one of the most widely used herbicides and it is used to prevent pre-emergence broadleaf weeds in crops

Excellent Crop Safety

KING'S ANGEL is safe for all the Maize species at all the growth stages

Long-lasting Protection

The long-lasting residual activity of KING'S ANGEL can help growers manage difficult weeds longer into one season which helps save time and labor

Application Flexibility

KING'S ANGEL is very flexible as far as time of application is concerned.

It gives a high level of control against broadleaf weed from the two-leaf to the four-leaf stage and grassy weed before the three-leaf stage.

The Control Efficacy

After 15 days of using KING’S ANGEL, monocotyledon and dicotyledon weeds were removed and no new weeds grew after 30 days.
