Understand the Growth and Development Stages of Corn






The understanding of how corn grows and develops can help the producers to prevent loss of crop and enhance the potential yield. The damage to crops can be minimized if a timely assessment can be done and the herbicides can be applied at the right time. Also, the right agriculture equipment is necessary for the proper planting of seeds and covering the seed furrow. 

The growth of the corn plants is either at the vegetative stage or at reproductive periods.    The vegetative stage of the corn starts at the time of the emergence of the seeding and it goes on till the tassel starts emerging as the reproductive stage of the corn begins. When it is at the vegetative stage, the leaves grow and develop along with the formation of the stalk.

Growth stages of corn

From early May to mid of July, the vegetative stage of the corns occurs. The stage of reproduction begins with pollination and when the grain becomes fully formed it is the end of the reproductive stage. Mid-July to mid-September is the period of reproductive stage of the corns.

Atmospheric temperature is one of the major parameters that are crucial for the growth and development of grains. Ideal temperature is not only necessary at the time of germination and emergence but also at the time of storing according to the grain bin weather station.

Vegetative Growth stage of Corn

The vegetative stage of the corn can be assessed by the growing point which is symbolized by a small triangle forms almost near to the top of the stalk tissue.  This is not visible above the soil as it is present below the surface of the soil.

The growing point of the corn refers to the group of rapidly dividing cells that are able to produce new leaves.  Generally, a new leaf of the corn plant takes four days to develop till the group of cells have reached the point of developing reproductive structures that are ear and tassel.  On average, about 16-20 leaves develop on a single corn plant.

The growth of the corn is mainly developed below the soil and it takes about two to three weeks for the plant to emerge.  This is helpful for the protection of the plant from frost and cold in the early stages of development. Otherwise, the plant becomes prone to more damage.  The early vegetative growth of the corn includes the development of root as well as leaf along with the expansion.

After three weeks of the emergence of the plant, the stalk starts to grow and develop above the surface of the soil. The plant can develop about 8 to 10 leaves at this stage. The stalk develops and grows upward as well as horizontally.   The growth of corn plants is primarily done from the growing point where the leaves are originated. In case of hail, frost, or rain, there are lower chances of survival of the plant, and the yield is reduced.

The right agriculture equipment when planting the corn seeds

When planting the corn seeds, it is essential that seeds should germinate and emerge at the same time and faster for higher potential yield. Therefore, the use of the right agriculture equipment is the key to increase the chances of faster and consistent germination and the emergence of the seeds. Germinator Closing Wheel is one of the most effective agriculture equipment that the producers can employ with their planters when planting the seeds. Germinator Closing Wheel covers the seed ā€˜Vā€™ properly and increases the chances of proper development of the roots as well as the stalk of corn. Besides, it eliminates the sidewall compaction so the roots can expand and grow deep strongly. As a result, the loss of seeds per acre per bushel is lowered and the potential yield is higher.
