Did You Know?
1. Corn is a water-hungry crop, requiring an average of 1 inch (2.5 cm) of water per week during the growing season.
2. Interestingly, ancient civilizations such as the Mayans and Aztecs relied on a unique agricultural technique called “chinampas” to grow corn. These floating gardens allowed crops to be cultivated on artificial rafts in shallow lakes, eliminating the need for excessive water consumption.
3. In the United States, corn is not only used for food production but also plays a vital role in the production of ethanol as a fuel additive. Approximately 40% of the U.S. corn crop is used for ethanol production.
4. When it comes to water consumption, one unanticipated fact is that corn grown for seed production requires significantly less water relative to corn grown for grain. This is due to the fact that seed corn plants are often spaced further apart, reducing competition for water and nutrients.
5. While corn thrives in moist soil, excessive water during certain stages of growth can actually be detrimental. Overwatering corn can stunt its root development and lead to shallow root systems, making plants more susceptible to being toppled over by strong winds.
Corn’s Water Requirements: 1 Inch Per Week
Corn, scientifically known as Zea mays, is a warm-season crop that is widely cultivated around the world. As one of the most important staple crops, corn requires adequate amounts of water to grow and produce abundant harvests. The amount of water needed is crucial to ensure optimal growth, especially during critical stages such as tasseling and kernel development.
To meet its water requirements, corn necessitates approximately 1 inch of water per week. This amount is taken into consideration to ensure the healthy growth of the plant, promote nutrient absorption, and maximize crop yields. Insufficient water can lead to water stress and negatively impact corn’s overall health and productivity.
- Key points:
- Corn is a warm-season crop.
- Corn requires adequate water for optimal growth.
- 1 inch of water per week is needed for healthy growth.
- Water stress can negatively impact corn.
Water Stress Impacts Corn’s Kernel Development
Water stress is a major concern for corn production. Insufficient water during the critical stages of pollination and kernel development can have detrimental effects on corn yields. In particular, water stress during tasseling can lead to ears with missing kernels, which significantly reduces overall productivity.
Tasseling is the reproductive stage of corn growth, wherein stalks produce tassels that release pollen. During this stage, if the plant doesn’t receive adequate water, pollen production and distribution may be compromised, resulting in incomplete pollination. Consequently, this can cause ears with gaps or missing kernels, ultimately diminishing both the quality and quantity of the harvest.
Efficient Irrigation Methods For Corn
Efficient irrigation methods are crucial for ensuring that corn receives the necessary amount of water to thrive and produce abundant harvests. Two popular methods for watering corn are soaker hoses and drip irrigation. These methods allow water to be delivered directly to the soil surface, reducing evaporation and ensuring efficient water uptake by the roots.
Soaker hoses are porous tubes that release water slowly along their length. Strategically placed along the crop rows, soaker hoses can deliver water directly to the root zone without wasting water on non-target areas.
Drip irrigation, on the other hand, utilizes a network of tubes with small emitters that release water in droplets at a controlled rate. Both methods are effective in promoting optimal growth by providing water directly to the roots.
Importance Of Watering At The Soil Surface
Watering corn at the soil surface is essential for several reasons. First, watering at ground level helps to minimize leaf wetting, which can reduce the risk of disease development. Moisture on the leaves can create a favorable environment for fungal growth, potentially resulting in diseases such as rust or blight.
Second, watering at the soil surface ensures that water is directly available to the plant’s roots, where it is most needed. This method allows the roots to efficiently absorb the water, maximizing nutrient uptake and supporting healthy plant growth.
Lastly, watering at the soil surface helps to minimize water loss through evaporation. By reducing water evaporation from the surface, more water is available for the plant, further supporting its growth and development.
- Watering at ground level minimizes leaf wetting
- Water directly available to roots for optimal nutrient uptake
- Reduces water loss through evaporation
“Watering at the soil surface is crucial for corn as it minimizes leaf wetting, reduces the risk of disease development, maximizes nutrient uptake, and conserves water.”
Preventing Missing Kernels: Proper Watering During Tasseling
To ensure a bountiful harvest and prevent missing kernels, it is crucial to provide adequate water during the tasseling stage of corn growth. Water stress during this stage can significantly impact pollination, resulting in ears with gaps or missing kernels.
The timing and amount of water during tasseling are critical. It is recommended to increase the frequency and amount of water applied, delivering close to the weekly 1-inch requirement during this stage. Ensuring that the soil is adequately moist during tasseling will promote healthy pollen production and distribution, increasing the chances of successful fertilization and kernel development.
Tip: Efficient irrigation methods such as soaker hoses and drip irrigation, combined with watering at the soil surface, can help maximize water uptake and minimize the risk of missing kernels.
By providing the optimal amount of water at the right time, farmers can ensure healthy corn plants and achieve plentiful yields.
- Proper watering practices during critical stages like tasseling
- Utilizing efficient irrigation methods
- Providing optimal water uptake and minimizing the risk of missing kernels.

Frequently Asked Questions
Does corn need to be watered everyday?
Corn does not need to be watered every day, but it does require a consistent supply of moisture to thrive. As a member of the grass family, corn is a high-demand moisture crop that relies on the soil being consistently near 75% moisture content. In most cases, providing the crop with an inch of water per week should suffice, wetting the soil to a depth of at least 5 inches. However, soil conditions, such as sandy soil, may require slightly more water to meet the crop’s needs. Therefore, regular watering is essential to ensure optimal growth and yield for corn.
Can corn get too much water?
While the corn plant has a certain level of tolerance for drought, it can indeed suffer negative consequences if given excessive amounts of water. When corn is overwatered, it becomes more susceptible to disease and shows symptoms such as yellowing leaves, root rot, and leaf drop. This is because the excessive moisture can create a favorable environment for diseases to thrive, compromising the well-being of the corn plant. Therefore, while water is essential for corn plant growth, it is important to ensure that the plant receives an appropriate amount to avoid overwatering and its associated issues.
How much water can corn absorb?
Corn is a highly efficient water user, and research has revealed that during tasseling/silking, it can absorb approximately 0.28 to 0.30 inches of water per day, equivalent to around 2 inches per week. These findings were obtained using the leaf collar method, which accurately measures the water use rates at different growth and developmental stages of corn. This information highlights the significant water requirements of corn during key periods of its growth cycle.
Do corn plants like water?
Corn plants require regular and adequate watering to thrive. They prefer soil that is consistently moist but not overly saturated. To provide optimal conditions for corn plants, it is recommended to water them whenever the top 1 inch of the soil feels dry during the active growth periods in spring and summer. However, it is important to be cautious and reduce watering during the fall and winter months, allowing the top 2 inches of soil to dry out before watering again. By maintaining the right level of moisture, corn plants can grow healthily and flourish.
