Potential of Corn Yield
Knowing about corn yield potential helps you in formulating a harvest plan. There are many different ways of estimating this corn yield based on the time you plan to harvest in the growing season. Your crop will play a huge role in the estimation process. You need to take out random corn samples to ensure that the corn yield estimation is done correctly.
One sample can be chosen from every 15 acres unless there are variable circumstances. If the field is non-uniform, you need to gather more samples to estimate the estimation.
Two of the ways using which the corn yield potential can be estimated are the corn yield component and corn ear weight. These methods can produce the yield estimate within about 20 bu/acre of the actual yield. Any of the methods can be used to measure the potential of corn yield.
Understanding Soil Fertility for Corn Growth
Soil fertility is an essential part of plant growth. If the soil is not fertile, then your plant will not grow the way you want, no matter what you do. Soil can be called fertile if the necessary nutrients are present in it. The three key nutrients that you need to see are Nitrogen (N), Phosphorous (P), and Potassium (K).
If you have land where the soil lacks certain nutrients, you need to prepare the soil before harvesting. There are other nutrients such as sulfur and zinc that are also necessary for fertile soil. Deficiency in any of these nutrients will not be good for the soil. However, you need to ensure that these nutrients should be present in the right amount.
Corn can grow best in a loamy soil. Along with these nutrients, there should be beneficial organisms present in the soil. The ideal soil would be about six feet deep for corn growth, along with a loose and medium texture. The capacity for holding water should be good, including good drainage properties.
The soil should be able to provide the necessary nutrients to your crop. Fertile soil for corn is that where there are equal parts of water and air in addition to organic matter. The air would be beneficial for the roots, while the water would enhance the plant growth. Humus or organic matter will be a storehouse for nutrients and hold the water.
This gives the soil the necessary texture and reduces the risk of erosion. It also detoxifies the soil and protects the crop from pests and diseases. Other necessary elements are oxygen, carbon, and hydrogen that form carbohydrates, vitamins, proteins, fats, and other products. This can be achieved through photosynthesis. All of this can help in making the soil fertile for the growth of corn.
How to Fertilize Sweet Corn for Optimum Growth
Sweet corn needs soil, whose pH level is between the range of 5.8 and 6.5. The pH level of the soil can be determined through strips for soil testing. This will be a great help in choosing the right kind of fertilizer for your sweet corn field. Since sweet corn takes up a high quantity of nutrients, you need to use fertilizers to provide the same.
The fertilizer should be rich in nutrients so that the soil does not get depleted. If the crop cannot get nutrients from fertilizer, it will absorb whatever they find within the soil. This can affect the soil’s quality and create an impact on the growth of the crop.
Identifying the Needs of Your Corn Yield
When you plant your corn, you need to take care of the yield. Whether it is the fertilization process or the growth process, many things can impact your corn growth. Without understanding your corn yield’s needs, you will not be able to grow a healthy plant.
Below are a few things that you need to pay attention to for a good yield. These include knowing the different growth stages and choosing fertilizers. It also consists of the tips that you need to follow before you start your planting process and what to do when sprouts start to grow.
How To Fertilize Based On Corn Growth Stages?
There are four main growth stages in corn crops, where different play important roles. Understanding the fertilization needs of each of these stages will give you an idea of what nutrients to offer and in which way.
Soil – Drilling
- Nitrogen for early growth
- Phosphorous and zinc to shoot growth and maximize the development of roots
- Calcium for improvising the root growth and make the plant string through cell strength enhancement
Emergence – V6
- Nitrogen is the main component in this stage. It enhances development and growth
- Phosphorous and potassium promotes leaf growth and strength
- Magnesium and sulfur contributes to the health of the leaves
- Boron and zinc contribute to new growth
- Several other micronutrients for not limiting the enhancement to photosynthetic growth
V6 – VT (Stem Extension – Tasseling)
- Potassium for protein synthesis and yield
- Nitrogen amount is reduced for maintaining dry matter with the production of protein
- Sulfur, magnesium, and other micronutrients for enhanced leaf growth and strength, grain proteins, and canopy development
R1 – R6 (Reproductive Growth)
- Potassium for maximizing the yield and crop growth
- Nitrogen ensures that the potassium is balanced and protein levels are good
- Boron contributes to grain ser and growth of pollen tube
- Zinc for sustaining the high uptake while the grain filling process is occurring
All of the nutrients mentioned above should be provided in proper quantity to work their magic. Even if all the stages use the same nutrient, the amount will increase or decrease depending on the need. Proper attention should be given to the quantity for healthy, mature growth.
Steps To Follow Before You Plant Corn Seeds
Before you start planting your corn seeds, there are certain things that you need to follow. Choosing the seed is the first thing that you will have to do. Your whole yield depends on the kind of seed that you plant. Along with that, you need to check the kind of plant that you are planting the seeds on.
The nutrients present on the soil and the nutrients required by the soil have to be checked. A proper balance of the necessary nutrients that will help in corn growth is required. Also, make sure that you choose the right fertilizer from the planting stage itself for optimum results.
What to Do When Sprouts Start Growing?
In corn, sprouts can start growing very quickly if the right care is taken. Fertilization is the key here, and you need to make sure that this fertilization process continues till the time your corn becomes mature. When sprouts start to grow, you can reduce the amount of fertilizer you have been using.
As the plant grows, the need for a growth boost is reduced, and more focus is given on its maintenance. Ensure that the plant received adequate water so that the sprouts do not shrink up and become dry. Additionally, any damaged or dried sprouts should be removed from the plant immediately.

Frequently Asked Questions
1. Can Corn Be Over Fertilized?
Yes, corn can be over-fertilized, and the results can be very harmful to your crop. Many people think that applying more fertilizers may make the growth process. However, this is not how fertilizer works.
Too much fertilizer can damage the corn or even kill the plant permanently. That is why you need to apply fertilizers very cautiously. Any fertilizer, you will have application instructions provided with it. You need to follow these instructions so that you do not accidentally put more fertilizer into your crop.
The difference in the amount of fertilizer will also vary depending on your crop’s maturity and land size. The soil’s ability to retain nutrients also plays an essential role in this process. Hence, you need to check every factor and then apply fertilizer to not over-fertilize your corn.
2. Should The Brown Tips Of The Corn Plant Be Cut?
Corn Plant, also known as Dracaena Fragrans, is a very well-known houseplant. The most common problem will see in this plant will be brown tips. This can occur due to many reasons and is not something that you need to worry about. This problem can be handled very easily.
Brown tips in corn plants are caused due to inconsistent watering or under-watering. There are other reasons, such as high chlorine and fluoride content in water and stress caused by repotting and acclimation.
To trim the brown tips, you can take the help of a shear. Only get rid of the damaged parts and do not touch the healthy part of the plant. Ensure that the tool you use to cut the damaged part is sharp to clean the cut without damaging the remaining portion.
3. Will Corn Deplete Soil?
Yes, corn can deplete the soil due to the high demand for nutrients. If the crop lacks proper attention, it can take the entire nutrient from the soil and deplete it with time. That is why most people plant other crops besides corn. Some of these plants are legumes, mostly beans that can minimize this depletion of nutrients.
Legumes will be able to balance the most important in the soil, which is nitrogen. Since corn needs more amount of nitrogen and legumes cultivate beneficial bacteria. The bacteria cultivated can pull the required amount of nitrogen and goes through nitrogen fixation to transform it into plant food.
To save the soil, you can do the same and plant legumes in between your corn yields. You can use good fertilizers to provide your crop with other necessary nutrients.
4. Can I Use Coffee Grounds For My Corn?
Yes, coffee grounds can be added to your corn yield. Many people add coffee grounds to various plants, including corn. Corn can have a very good reaction to coffee grounds and have enhanced growth very quickly. Coffee grounds enhance the soil texture and also drain away from the water after heavy rainfall.
Slowly the coffee grounds added to the soil start decomposing and add the three main nutrients: nitrogen, phosphorous, and potassium. One thing to remember is that coffee grounds are not a substitute for fertilizers. You will still have to use proper fertilizers even when you use coffee grounds.
Coffee grounds are often perceived as highly acidic, but the coffee grounds’ pH level gets reduced once they have been brewed. This does not harm the crops, and the balance of the nutrients is maintained as needed by corn.
