How does water affect corn plant growth?

Corn plants will fight to thrive depending on growing season conditions. When stressed for water, corn plants will send down roots deep enough to reach moisture. In a relatively moist year, corn plants put down strong roots but at more shallow depths.

What are the developmental stages of corn?

The description of the essential processes that fuel plant growth leads to an explanation of the developmental stages of corn. Topics include vegetative growth, the transition to reproductive growth, pollination/fertilization, and the stages of grain development. Biology of Corn 1 covers the parts of the corn plant and their functions.

What is the future of growing corn?

In a relatively moist year, corn plants put down strong roots but at more shallow depths. With accidental innovators like Harry Stine pushing out proven research, higher corn yields that correlate directly with higher corn populations is just the tip of the iceberg in terms of the future of growing corn.

What are the 3 main topics in corn biology?

Topics include vegetative growth, the transition to reproductive growth, pollination/fertilization, and the stages of grain development. Biology of Corn 1 covers the parts of the corn plant and their functions. Biology of Corn 2 covers growth and development of corn. Biology of Corn 3 covers corn taxonomy and classification.

What is yield contest?

Yield contests are perfect resources for finding how to boost your bushels per acre. Although plots are often under intense management, yield contest plots a great way to see what results can come from heavy scouting, sampling, and responding quickly to plant needs. If entering a contest, start with the basics and look for room for improvement. And if watching, take notes!

How do corn plants survive?

When stressed for water, corn plants will send down roots deep enough to reach moisture. In a relatively moist year, corn plants put down strong roots but at more shallow depths.

What temperature should corn be planted at?

When farmers are itching to get into the fields to plant, it’s important to remember that soil temperatures should be at 50°F. for a strong start for corn seed germination. Corn planting time all depends on the seed variety being planted and, of course, weather conditions.

What is gene editing?

The use of gene editing is the secret sauce behind the impressive corn plants of the future. Unlike genetically modified organism (GMO) technology, gene editing can change the behavior of a plant without introducing any foreign material into the plant.

How long can corn survive in water?

If weather works against the seedlings, replanting may be an option. Young corn can’t survive in standing water for over four days and sometimes last only 48 hours before oxygen levels drop off.

What are the two main types of corn?

There are two main types of corn – sweet corn and field corn .

What is high yield?

High yields are the trophy at the end of the marathon that is the growing season. If high-yield factors like nutrients, hybrid type, plant populations, and specific management practices are in place, agronomists see consistent yield increases when applying a fungicide at tassel.

How does corn starch help the ethanol industry?

Infrastructure to plant, harvest, and store corn in mass quantities benefits the corn ethanol industry. Unlike sugarcane, in which squeezed sugar water can be directly fermented, corn starch must be cooked with alpha and gluco-amylase enzymes to convert the starch to simple sugars.

How much corn is used for ethanol?

Using the current corn-to-ethanol conversion of 2.8 gallons of ethanol from a bushel of corn, total U.S. corn production could result in approximately 37 billion gallons of ethanol, which would provide approximately 26% of our 137 billion gallon-per-year gasoline consumption (Energy Information Administration). However, using all of our corn for ethanol is neither realistic nor necessary and has not been proposed. Creating the 15 billion gallons required under the RFS-2 would call for 5.4 billion bushels or about 41% of our 2009 corn crop. Although this percentage seems rather high, one-third of the weight and 100% of the nutritional content of corn entering an ethanol dry mill biorefinery is returned to the feed market as distillers grains. These distillers grains can be used to replace corn in the diets of cattle, swine, and poultry. When this replacement is calculated into the overall consumption figures, it lowers the number to 27% of our 2009 corn crop, or only 3.6 billion bushels of corn to produce the 15 billion required gallons. Throughout history, the United States has seen a steady increase in the yields of both corn and ethanol production. It is very likely that the United States will be able to increase corn ethanol production without expanding to new acres and still have plenty of corn remaining to meet other domestic use and export demands.

What is the energy ratio of corn ethanol?

Life cycle analysis (LCA) of ethanol production from corn grain has yielded a net energy ratio of 1.2 to 1.45 (Liska et al., 2009), which represents just a 20% to 45% positive energy balance in producing ethanol from corn. A major criticism of corn ethanol has been the large amount of fossil energy used in production.

What is the main feedstock for ethanol?

Corn ( Zea mays) is a popular feedstock for ethanol production in the United States due to its abundance and relative ease of conversion to ethyl alcohol (ethanol). Corn and other high-starch grains have been converted into ethanol for thousands of years, yet only in the past century has its use as fuel greatly expanded.

How much water does corn need?

To produce grain, corn will use approximately 22 to 28 inches of water, which requires 12 to 20 inches of rainfall or irrigation during the growing season (Al-Kaisi, 2000; Hoeft et al., 2000; Kranz et al., 2008).

What can distillers be used for?

These distillers grains can be used to replace corn in the diets of cattle, swine, and poultry. When this replacement is calculated into the overall consumption figures, it lowers the number to 27% of our 2009 corn crop, or only 3.6 billion bushels of corn to produce the 15 billion required gallons.

What are the steps of conversion of ethanol?

For fuel ethanol, two more steps are included: using a molecular sieve to remove the last of the water and denaturing to make the ethanol undrinkable.

What does Licht say about second field?

Licht says many producers get into more trouble on the second field they plant. “They wait and follow directions on the first field, then the spring rains come, and they see a two-day window, so they hit the second field too soon. When you think you’re ready, wait another one-half day. You’ll be better off.”.

What is the first step in corn planting?

The first step in successful corn planting is understanding the land. Soil type matters, as does slope and drainage of the field.

What temperature should soil be for a sandbox?

Soil temperatures need to be at least 50°F. with a 5- to 14-day warming trend ahead. 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.

How many seeds per acre?

Licht says 33,000-38,000 seeds per acre is an ideal range for much of the Midwest. A higher rate may maximize yield, but a lower rate may be more economical when factoring in the cost of seed. Watch the season-long weather report. Plant lighter in a dry season so there is less competition for moisture. In a wetter year, you can bump up your rate.

What determines whether or not to apply starter fertilizer?

Soil fertility will determine whether or not to apply a starter fertilizer when planting, so it is important to know your soil test levels.

Do seed companies give discounts?

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.
