Sweet corn needs ample water from germination to harvest, but the most critical period for water is about 2 weeks before silks form. Aim for 1 inch of water per week, and supplement natural rainfall with irrigation as needed.
How often should corn be watered?
The Corn plant requires moderate watering. Water thoroughly once every 7 – 10 days or when the soil is dry to touch down 1 inch into the soil. The roots of the Corn plant are located close to the canes.
How much water does a sweet corn plant need?
Sweet Corn Crop Guide
| Estimated Cost | $500 to $1000 per acre up to harvest |
|---|---|
| Soil Requirements | Medium to heavy soils preferred |
| Water Requirements | Sweet corn needs 20 – 35 acre-inches of water. Critical water peaks are during pre-tassle and kernel fill. |
| Minimum Size | 1 acre hand harvest – 20 acre for mashine harvest |
Does corn need to be watered every day?
Corn has deep roots, so you need to water long enough that water reaches a depth of 30–36 inches. Because corn benefits from deep, soaking watering, it’s best to water once per week rather than daily, as this ensures adequate soil moisture.
Does corn use a lot of water?
A high-yielding corn crop uses about 600,000 gallons of water per acre. An acre of corn releases approximately 4,000 gallons of water a day in evaporation. Corn uses nearly 3,000 gallons of water for each bushel of yield. Finally, it takes approximately 127 gallons of water to produce one pound of corn.
When should you stop watering corn?
Like field corn, irrigation for sweet corn should terminate at maturity. For sweet corn, this could be anywhere from 60 to 100 days.
Does corn need a lot of sun?
Corn grows best in loamy, well-drained soil under full sun — six to eight hours of unfiltered sunlight daily.
Why is my corn dying?
If you have withering corn plants, the most likely cause is environmental. Corn plant problems such as wilting may be the result of temperature fluxes and irrigation, although there are some diseases that afflict corn plants that may result in wilted corn plants, too.
Why are my corn leaves turning yellow?
Yellowing leaves are often a sign of a problem with the nutrient uptake process, either due to water competition from nearby grass or drought conditions. Corn plants get 13 of the 16 required nutrients for growth through the soil, either through direct contact as roots grow or via mass flow or diffusion.
How do you grow sweet corn successfully?
Plant seeds one inch deep, and eight to 12 inches apart, with rows 30 to 36 inches apart. Plant in blocks of at least four rows rather than a long single row for proper pollination. Small, lightweight Shrunken (sh) kernels demand the most care at planting. Do not plant them deeper than three-fourths to one inch.
At what stage does corn need the most water?
Corn requires the most water during the early reproductive growth stages (Table 1), which are also the most sensitive stages to water stress. Substantial reductions in yield can occur if corn does not receive enough water to meet ET demands during this critical water use period.
What time of day should I water corn?
Water sweet corn whenever the soil surface dries out, but don’t saturate the soil. The surface should feel just moist to the touch and water should drain away from around the plants within 10 to 20 seconds. Water first thing in the morning so any moisture that gets on the leaves has time to dry during the day.
Why is my corn plant turning yellow and brown?
The problem you are experiencing is probably due to inconsistent watering. If the soil dries out too much the tips of the leaves will turn brown. Of course, you don’t want to over water either, especially in winter when growth has slowed, because this can lead to root rot.
What crop needs the most water?
Take rice. It’s the most water-intensive crop and the fourth-biggest user of water. Yet rice generates only $374 per acre-foot of water.
How much water does sweet corn need a day?
Sweet corn needs ample water from germination to harvest, but the most critical period for water is about 2 weeks before silks form. Aim for 1 inch of water per week, and supplement natural rainfall with irrigation as needed.
Which food requires the most water?
Breaking up meat’s monopoly as the most thirsty food type is nuts, with 9,063 liters of water needed to produce the average kilo. Further down the scale are fruits and vegetables, requiring 962 and 322 liters per kilogram respectively.
Can you over irrigate corn?
Of course, excessive irrigation/rainfall and soil saturation will stunt plant growth, reduce corn yield potential and promote nitrogen loss as well.
How much water does corn need after Dent?
Thankfully, corn moisture requirement steadily drops from a peak of 1.5-1.75 inches per week prior to the dough stage (four weeks post tassel) to an inch or less per week after dent and even lower as the grain approaches physiological maturity.
Why do we need to stop irrigation one week before harvesting?
This soil moisture level also minimizes physical tuber damage. If soil is dry before harvest, a final irrigation should be applied at least one week prior to harvest to raise the soil moisture level and raise the tuber hydration level.
What is the best fertilizer for sweet corn?

How long does sweetcorn take to grow?
about three months
Sweet corn is a fast-growing annual that is planted in spring and grows through the summer. It is ready to harvest about three months after planting, but early varieties can be ready in as little as two months.
