Corn Development Stages: From Emergence To Pollination
Understanding the different stages of corn development is crucial for monitoring the growth of the plants and ensuring their optimal care. The development stages of corn can be divided into several different phases:
-
VE stage (emergence): This stage usually occurs within 4 to 5 days after planting under ideal conditions. However, it can take up to 2 weeks or longer under cool or dry conditions.
-
V1-V5 stages: At the V1 stage, a round-tipped leaf on the first collar appears, and nodal roots begin to elongate. By the V2 stage, the plant is 2 to 4 inches tall. The V3 stage, which occurs 2 to 4 weeks after emergence, marks the point where the plant switches from relying on kernel reserves to photosynthesis. At the V4 stage, it is crucial to control broadleaf weeds. By the V5 stage, the number of potential leaf and ear shoots are determined, and the plant reaches a height of 8 to 12 inches.
-
V6-V8 stages: These stages begin around 4 to 6 weeks after emergence. The growing point of the plant starts to grow above the soil surface, and the nodal root system becomes dominant. The V7 stage marks the beginning of the rapid growth phase and stem elongation. By the V8 stage, the plant reaches a height of 24 inches.
-
V9-V11 stages: These stages occur around 6 to 8 weeks after emergence. The corn plants enter a period of steady and rapid growth. At the V9 stage, the tassel starts to develop rapidly, and new leaves appear every 2 to 3 days. The ear shoots also begin to develop during this stage.
-
V12-Vnth stages: By the V12 stage, the plant is about 4 feet tall or even taller. Nutrients and water are in high demand at this stage. All leaves are full size, and roughly half of them are exposed to sunlight. Brace roots start to develop, and the plant is about two weeks away from silking at the V15 stage.
-
VT stage (tassel emergence): This stage begins around 9 to 10 weeks after emergence. During this stage, the corn enters the critical period of pollination. The tassels become fully visible, and silks start to emerge within 2 to 3 days. Pollen shed begins and continues for about 1 to 2 weeks.
Factors Affecting Corn Growth: Hail, Insects, And Nutrient Deficiencies.
While corn plants generally have the ability to grow and develop under favorable conditions, there are several factors that can significantly impact their growth and yield potential. These include hail, insects, and nutrient deficiencies.
Hailstorms can cause severe damage to corn plants, resulting in a significant reduction in yield. The physical impact of hail can break or damage the plants, leading to a loss of foliage and reduced photosynthesis. To protect corn plants from hailstorms, implementing preventive measures such as installing hail nets can be effective.
Insects, including pests like aphids, corn borers, and rootworms, pose a significant threat to corn plants. These insects feed on the plants, damaging the leaves and stems, which ultimately affects their growth and development. To control insect pests, the use of appropriate insecticides can be employed.
Nutrient deficiencies can also hinder corn growth and reduce yields. Corn plants require a balanced supply of essential nutrients, such as nitrogen, phosphorus, and potassium, to thrive. Deficiencies in these nutrients can manifest in various ways, including stunted growth, yellowing leaves, or poor kernel development. Regular soil testing and appropriate fertilization can help address nutrient deficiencies and ensure optimal plant growth.
In summary, to maximize corn growth and yield, it is crucial to take preventive measures against hailstorms and insect pests. Additionally, addressing nutrient deficiencies through regular soil testing and proper fertilization is essential. With these measures in place, successful corn cultivation can be achieved, leading to a rewarding harvest of freshly grown corn.

Frequently Asked Questions
How long does it take for corn to fully grow?
Corn is a crop that thrives in a relatively short span of time. Once the kernels are planted between April and June, the growth process accelerates, allowing farmers to reap the harvest from July to October, a mere eight weeks later. This quick turnaround not only makes corn a popular choice among farmers but also contributes to its overall productivity as a crop.
How much can a corn plant grow in a day?
A corn plant has the remarkable ability to rapidly grow once it reaches a certain height. After slowly reaching approximately 24 inches in height, it can then undergo a growth spurt, adding an impressive 3 to 4 inches per day during hot weather. Interestingly, there is a belief that planting corn under a waning Moon can result in a slower growth rate but ultimately yield larger ears.
How long does corn take to crop?
The time it takes for corn to crop can range from 72 to 110 days, depending on the specific variety. It is important to refer to the seed packet for the days to maturity to get a general idea of when the corn will be ready for harvest. This ensures that farmers and gardeners can plan their harvesting schedule accordingly.
How many corn do you get from one plant?
The number of corn you get from one plant can vary depending on the variety and maturity of the plant. Generally, most sweet corn varieties will yield one to two ears per plant. The early maturing types typically produce one ear, while those that mature later can have two harvestable ears. This variation is due to the rapid growth and relatively shorter stature of sweet corn plants.
