Plant a population of seeds for the most effective emergence. The preferred recommendation is planting 10% more seeds than the final crop yield you are aiming to achieve. The industry average for germination is around 95%, and while De Dell seeds have a history of performing well north of that, it is always a good idea to mitigate risks beyond your control whenever possible.
Ensure that the soil you are planting in is moist. If your soil is dry, it makes it more difficult for the seed to latch into the dirt and grow effectively. However, you must also be mindful to avoid the effects of soil compaction. Soil compaction occurs when the ground does not allow nutrients to reach the seed, and can happen when your soil becomes too moist. Moisture can be gained through irrigation and natural conditions, while soil compaction is fought off by avoiding excessive field work.
Planting correctly isn’t only about having the right soil conditions; the depth of your corn seeds is also important. If seeds are planted too shallow then they will have nowhere to grow; if they are planted too deep then cold soil can negate their growth. The ideal depth is between 3-5 cm, shallow enough for the warmer temperatures that exist near the surface, but also still deep enough to access moisture that seeds need to grow effectively.
Proper spacing for growth
When planting corn in rows, you want to ensure the you give each plant enough space to thrive. Most corn hybrids have a flex type ear on them which will continue to grow under the proper conditions. These types of hybrids like to be planted at a moderate population between 28,000 to 32,000 plants per acre. Other hybrids have a more determinant ear which means they grow to a fixed size and can handle a higher planting population from 32,000 to as high as 40,000 plants per acre. Consult with your local De Dell Dealer for the optimal planting populations for hybrids on your farm.
Plant with Uniformity
The best way to plant corn seeds is to plant with uniformity. As your corn is emerging, it’s important that it isn’t overshadowing other corn crops that are just beginning to grow. If corn is overshadowed, it will lose out on important wind pollination. Planting corn in uniform rows can help mitigate risk of overshadowing so that your corn crops have access to the elements they need to grow.
The corn planting process is dependant on soil temperature, as corn tends to struggle in cooler and extremely hot temperatures. The optimum soil temperature for growth of corn occurs at any point above 10 degrees celsius. On the other hand, growing corn becomes risky when your soil is warmer than 38 degrees. Keep things pleasantly warm, and avoid overly hot soil conditions.
Certain soil types lend themselves more to planting corn, and it is important to know whether or not your soil is suited for optimized growth and emergence. For example, fine-textured soils are less able to hold onto water and moisture, when compared to medium or coarse textured soils. Understanding the kind of soil you’re dealing with, such as a soil which takes longer to warm up to the temperatures needed for seed growth, is an essential aspect of growing corn.
Tiling Your Crops
Tilling is an important process when growing corn, because it can help loosen soil up to give it the best opportunity to grow seeds. When preparing to plant seed corn, ensure that you are tilling effectively — but not unnecessarily. Avoid working wet soil, because excessive tilling can hurt your soil’s ability to remain fertile, and therefore lowers potential crop yields.
