When to Stop Irrigating Corn: A Guide for Farmers

When To Stop Irrigating Corn?

Corn is a thirsty crop, and irrigation is essential to ensuring a healthy harvest. But how do you know when to stop irrigating corn?

There are a few factors to consider, including the weather forecast, the stage of growth of the corn, and the soil moisture content.

In this article, we’ll discuss each of these factors in detail and help you determine when it’s time to turn off the irrigation system.

We’ll also provide some tips on how to water corn efficiently and avoid wasting water.

So if you’re wondering when to stop irrigating corn, read on for the answers!

When To Stop Irrigating Corn?	Reason	Recommendation
When the corn silks are 60%-70% dry	This is when the corn is starting to mature and no longer needs as much water.	Reduce the amount of water you are giving the corn and gradually stop irrigating altogether.
When the corn ears are fully formed	The corn is now mature and does not need any more water.	Stop irrigating the corn completely.

Factors to Consider When Deciding When to Stop Irrigating Corn

There are a few factors to consider when deciding when to stop irrigating corn. These include:

• The stage of growth of the corn crop. Corn plants require more water during the vegetative stage of growth, when they are actively growing leaves and stalks. As the corn plants mature and begin to produce ears, they require less water.
• The weather conditions. Corn plants require more water during periods of drought or when the weather is hot and dry.
• The soil conditions. Corn plants that are growing in sandy or well-drained soils require less water than corn plants that are growing in heavy clay soils.
• The irrigation system. The type of irrigation system you are using can also affect how much water you need to apply. Drip irrigation systems are more efficient than sprinkler irrigation systems, so you can usually get away with applying less water with a drip system.

Once you have considered all of these factors, you can make an informed decision about when to stop irrigating your corn crop.

Signs That It Is Time to Stop Irrigating Corn

There are a few signs that it is time to stop irrigating your corn crop. These include:

• The corn plants have stopped growing new leaves.
• The corn plants are starting to turn yellow or brown.
• The soil around the corn plants is dry to the touch.
• The corn plants are starting to tassel.

If you see any of these signs, it is time to stop irrigating your corn crop.

Note: It is important to note that you should never stop irrigating your corn crop abruptly. If you do, the corn plants may experience water stress and damage. Instead, gradually reduce the amount of water you are applying over a period of several days.

Deciding when to stop irrigating corn is a decision that should be made based on a number of factors, including the stage of growth of the corn crop, the weather conditions, the soil conditions, and the irrigation system. By considering all of these factors, you can make an informed decision about when to stop irrigating your corn crop and ensure that your crop reaches maturity without experiencing water stress.

3. Methods for Stopping Irrigation

There are a few different methods for stopping irrigation, depending on the type of irrigation system you have and the time of year.

• For drip irrigation systems, you can simply turn off the water supply. This is the easiest method, but it may not be the most effective. If the soil is still wet, the water will continue to drain out of the soil, which can lead to waterlogging and root rot.
• For sprinkler irrigation systems, you can either turn off the water supply or gradually reduce the amount of water you’re applying. Gradually reducing the amount of water will help the soil dry out more evenly and prevent waterlogging.
• For flood irrigation systems, you can either turn off the water supply or gradually reduce the depth of the water. Gradually reducing the depth of the water will help the soil dry out more evenly and prevent waterlogging.

No matter which method you choose, it’s important to make sure that you stop irrigating gradually. This will help the soil dry out more evenly and prevent waterlogging and root rot.

4. Potential Consequences of Stopping Irrigation Too Early or Too Late

If you stop irrigating corn too early, the corn may not be able to produce a full crop. This is because the corn needs water to produce kernels. If the corn doesn’t get enough water, the kernels will be small and underdeveloped.

In addition, stopping irrigation too early can also lead to the corn plants becoming stressed. This stress can make the corn more susceptible to pests and diseases.

On the other hand, if you stop irrigating corn too late, the corn may not be able to mature properly. This is because the corn needs water to fill out the kernels. If the corn doesn’t get enough water, the kernels may not fill out properly and the corn may not be as sweet or flavorful.

In addition, stopping irrigation too late can also lead to the corn plants becoming stressed. This stress can make the corn more susceptible to pests and diseases.

It’s important to stop irrigating corn at the right time to ensure that the corn plants have enough water to produce a full crop and to avoid stress.

When to stop irrigating corn is a complex decision that depends on a number of factors, including the type of irrigation system you have, the time of year, and the weather conditions. By following the tips in this article, you can help ensure that your corn plants get the water they need to produce a healthy and bountiful crop.

When should I stop irrigating my corn?

There are a few factors to consider when determining when to stop irrigating your corn.

• The stage of growth of your corn. Corn is a thirsty crop, and it needs a lot of water to grow. However, the amount of water it needs decreases as it matures. Young corn plants need more water than mature corn plants.
• The weather conditions. If the weather is dry, you will need to irrigate your corn more often than if the weather is wet.
• The soil type. Corn plants that are growing in sandy soil will need more water than corn plants that are growing in clay soil.

Generally speaking, you should stop irrigating your corn when the corn ears are fully formed and the kernels are starting to dry down. This is usually around the time of silking. However, you may need to continue irrigating your corn if the weather is dry or if the soil is sandy.

How do I know if my corn needs water?

There are a few ways to tell if your corn needs water.

• The leaves of your corn plants will start to wilt if they are not getting enough water.
• The soil around your corn plants will start to dry out if they are not getting enough water.
• You can also check the moisture level of the soil by sticking your finger into it. If the soil is dry to the touch, your corn plants need water.

What happens if I stop irrigating my corn too early?

If you stop irrigating your corn too early, it may not produce as much corn as it could have. This is because corn plants need water to grow and develop properly. If they do not get enough water, they will not be able to produce as many kernels of corn.

What happens if I stop irrigating my corn too late?

If you stop irrigating your corn too late, it may start to develop dry rot. Dry rot is a fungal disease that can cause corn kernels to rot and fall off the cob. This can reduce the yield of your corn crop.

How can I prevent my corn from drying out during a drought?

There are a few things you can do to prevent your corn from drying out during a drought.

• Irrigate your corn regularly. This is the most important thing you can do to keep your corn plants healthy during a drought.
• Mulch your corn plants. Mulch helps to keep the soil moist and cool, which can help to reduce water evaporation.
• Plant your corn in a sheltered location. Corn plants that are sheltered from the wind will lose less water through evaporation.
• Water your corn early in the morning or late in the evening. This will help to reduce water evaporation.

By following these tips, you can help to keep your corn plants healthy and productive during a drought.

When to Stop Irrigating Corn?
