Growing Corn: Varieties, Planting Guide, Care, Problems and Harvest
Apr 06, аи Check planting depth when starting each field. In summary, corn should never be planted less than inches deep, to inches is an ideal target, but depending on soil type and conditions, may be planted up to 3 inches deep without any effect on stand establishment. Have a safe and successful planting season. Jul 11, аи Corn rows need to be spaced inches apart. Plant the seeds 1 1/ inches deep and inches apart. That gives each corn stalk space to grow. Cut a row with your tractor or a hoe (if you are planting in a smaller garden space) and drop the seeds in .
The first step in successful corn planting is understanding the land. Soil type matters, as does slope and drainage of the field. Flatlands are more suited to strip tillage that will aid in soil warming and drying, compared to sloped fields that are more suited to a no-till approach, according to Mark Licht, Iowa State University Extension and Outreach cropping systems specialist.
Flat areas with prairie potholes that can pond excessively in heavy rains simply may not be suitable for corn production. The next step is choosing the right seed. There are many varieties on the market, all developed with different goals in mind. If planting early, a full maturity variety will allow for early season vigor aapart quick fall dry down.
If planting is late, an earlier maturity variety is desired to wrap up the growing season before fall. You may want a trait package that includes herbicide or insecticide or choose a more conventional variety and make applications xpart the season dictates.
Picking a seed company is part of the decision. Some companies give a discount for quantity if you buy all your seed in a given year from them. Others may give a loyalty discount if you buy from them year after year. One of the advantages of consistently buying from the same company is familiarity with the product line-up. That may help navigate the overwhelming number of options, especially for the new producer.
Debate about the advantages of a inch or inch row is ongoing and depends in part on the hybrid genetics of your seed. Your seed salesmen can be of assistance in advising you as to row spacing and expected seed rate response. Licht says 33, seeds per acre is an ideal range fiwld much of the Midwest. A higher rate may maximize yield, but a lower rate may be more economical when factoring in fo cost of seed. Watch the season-long weather report. Plant lighter in a plajt season so there is less competition for moisture.
In a wetter year, you can bump up your rate. Others are married to a particular date no matter what or just want to beat their neighbor to the field.
But Licht says there are more reliable ways to determine the right time for planting. Field moisture needs to be adequate to germinate the seed, but not so wet it hampers plant emergence or vigor or causes equipment to create unnecessary compaction.
Federal crop insurance dictates when you can start planting in your state and qualify for the program. In Iowa, it is April Licht says many producers get into more trouble on the second field they plant.
The large planter is ideal for large fields with no fencerows, but it is not for everyone or every farm. Be sure to choose the right size planter for the size of your operation and your landscape.
Licht says a standard planter from your dealer will generally suffice, at least to start. Various attachments, like how to make apple vinegar cleaners, starter fertilizer, and insecticide delivery systems can be added later. Just the right amount of down pressure is needed to plant effectively without causing compaction, and that varies according to soil type and organic matter.
Soil fertility will determine whether or not to apply a starter fertilizer when planting, so it is important to know your soil test levels. Set up your planter with your desired seeding rate and make sure it is set for the right seed depth. Licht recommends 2 inches. As you are planting, make sure you get the furrow closed and you are not creating sidewall compaction.
Licht recommends getting out of the tractor every four to six hours to evaluate how the planter is performing. Settings that worked one day, or in the early morning, may not be as effective after temps and breezes have warmed and dried the soil. Once the fieldd is planted and the corn is growing, be sure to check the emerging corn and count the plant population. Are there doubles? Is the seed spacing what it should be? Are there skips? Understanding what you have will plqnt you manage potential problems through the growing season.
Weak root systems from compaction can lead to lodging in heavy winds, and a how to self harm with a razor blade stand is open to weed competition. So, walk your field, evaluate your work, plan fueld to manage your crop, and make adjustments for next year.

If you are growing a tall variety of corn, you need to plant the seeds further apart than if you are raising a smaller variety. You should plant seeds for tall corn in rows that are about three and a half feet (1 meter) apart. The space between each plant should be between seven and ten inches ( cm). Mar 13, аи Debate about the advantages of a inch or inch row is ongoing and depends in part on the hybrid genetics of your seed. Your seed salesmen can be of assistance in advising you as to row spacing and expected seed rate response. Licht says 33,, seeds per acre is an ideal range for much of the Midwest. May 26, аи Generally, space traditional rows of corn 36 inches apart and the plants 12 inches apart, for blocks of double rows; and 30 to 36 inches apart for rows that contain hills of corn. Importance of.
Gregory A. Luce University of Missouri luceg missouri. There are a lot of factors that influence corn stand and final yield. Some we cannot control and some we can. One easy way to give your corn crop the best opportunity for consistent stand level, and ultimately yield potential, is to plant at the proper depth. The old rule of thumb index finger in this case is to plant corn seed at a depth equal to the second knuckle on their index finger.
Well, not everybody has the same length fingers so a bit more accurate measurement is in order for this important management decision. University Extension publications across the Midwest typically recommend a corn seeding depth of 1. Most agronomists will agree that planting corn too shallow leads to more frequent problems than planting too deep. From my experiences, bad things happen when corn seed is planted shallower than 1. Therefore, I recommend targeting 2 inches as an excellent depth for corn planting.
A primary reason to target a 2 inch depth is to achieve good seed-to-soil contact. In order to accomplish this throughout the seedbed, the seed needs to be where the moisture levels are most consistent. Uneven soil moisture throughout the seed zone is the primary cause of uneven emergence, the results of which can easily be yield losses of 8 to 10 percent.
The second reason for the recommended planting depth is to establish a strong nodal root system. The nodal root system not only helps support the corn plant structurally, but is also responsible for uptake of the vast majority of the water and nutrients the plant needs.
A good nodal root system is essential in reducing early season root lodging as well as helping the plant perform better under drought stress later in the season. A shallower planting depth, especially less than 1. Heavy texture soils may require careful planting depth adjustment but it is still important too not plant too shallow. There are always exceptions to the rules that can rely on some fine tuning.
For instance, if soil conditions are dry at planting time, planting to moisture is often practiced to help uniformity of emergence. Soil texture is another factor to consider. In very heavy textured, high clay content soils, corn seeds should not be planted deeper than 2. However, in lighter sandy soils planting 3. In fact, planting 2. The conditions of every one of your fields may vary dramatically enough to warrant a slightly different seeding depth for each one. Growers should check corn seeding depths when they enter fields with different soil types or tillage practices.
It is a recommended practice to spend some time evaluating each field at the time of planting. In summary, corn should never be planted less than 1. All rights reserved.
