Corn growers maximize yield if they plant in april or may. If young plants don’t get damaged by a cold snap or frost, a mid-April planting date will produce the same yield. Spring planting dates for corn (Zea mays L.), soybeans (Glycine max), and cotton (Cottona spp.) in the U.S. and Canada. FAO.

How long does it take to grow sweet corn?
It takes two to three months from sowing seeds to picking corn. The number of days from sowing to harvest will usually be noted on the seed packet. After the seeds are sown, ‘Honey and Cream’ hybrid sweet corn takes 84 days to mature. Sweet corn can be grown in a variety of soil types, from sandy loam to clay loams.
It can also be planted in the ground, but it is best to plant it in soil that is rich in organic matter, such as peat moss or composted manure. If the soil is too dry, you may need to add a bit of water to moisten it before planting. You may also want to cover the plants with a layer of mulch to keep them from drying out during the growing season.
Does corn need a lot of water?
Depending on planting date, planting density, maturity group, location, and weather conditions, high yielding corn requires approximately 22 to 30 inches of water per year. The most sensitive stages to water stress are the early reproductive growth stages, which require the most water. Water requirements of corn (Zea mays L.) and soybean (Glycine max) grown at different planting densities.

Should you water corn everyday?
Water needs to reach a depth of 30–36 inches in order for corn to have deep roots. It’s best to water once per week rather than daily, as this ensures that the soil is well-hydrated and corn benefits from deep, soaking watering. Corn is a perennial plant, meaning that it grows year-round. This means that you can plant corn in the fall, and it will continue to grow throughout the winter.
If you plan on planting corn this year, be sure to plant it in a location that has plenty of sun, such as a sunny window sill or in an area that receives a lot of morning and afternoon sun. Corn is also a drought-tolerant plant that can tolerate a wide range of soil types.
How many corn cobs do you get per plant?
A single corn plant can produce between two and four ears of corn. The selection of cultivars is a matter of trial and error. It is best to start with a variety that is well suited to the climate and soil conditions in which the crop will be grown.
If, on the other hand, your crop is grown in a temperate climate, such as that of northern California, it will need to be selected for its ability to withstand the heat of summer and the cold of winter.
In either case, the selection should be made with the aim of producing a crop that can be harvested within a reasonable period of time, so that the farmer can make a profit on his investment.
How often does corn need to be watered?
It takes about 1 inch of water a week for corn to grow. Don’t forget to water your corn patch because water stress during pollination will result in ears with lots of missing kernels. Use a garden hose or a soaker hose to apply water to the soil.
If you’re growing corn in a greenhouse, you’ll need to water your plants as well. If your greenhouse is too hot or too cold, the plants won’t be able to take the water they need. You’ll also want to make sure you have enough water in your irrigation system to keep up with the growing season.
Does sweet corn need full sun?
For maximum growth and yield, sweet corn should receive full sun. pH of the soil should not be too acidic or too alkaline.
Too high of a pH will inhibit the growth of beneficial microorganisms, and too low of an acidity will cause the plant to become stunted and die. pH is too high, too much water will be lost through evaporation, which will reduce the amount of nutrients available for plant growth. It is important to keep soil pH within the range of 5.6-6.2.
This will allow the plants to absorb all the nutrients they need to grow well and produce healthy, high-yielding crops.
