Prairie Hybrids
Dear Customer, Have you visited your local grocery store recently, and noticed all the attention being focused on “Healthier”? ...or on Non-GMO, and maybe even Organic? As I’ve worked more closely with food companies, I’ve seen how the end-user is changing the entire food industry. (We all watched this summer as Amazon bought Whole Foods, right?) It is clear that Families are paying more attention to the ingredients in their food, and that is putting pressure on Ag to change and adapt. They’re even paying attention to what we are feeding our animals, and the health of our soils and water. They’re demanding “Healthier”. At Prairie Hybrids, we would like to say to these customers… “Welcome Back”! For over 45 years Prairie Hybrids has been a promoter of “Healthier”, with Non-GMO and Organic.
My father (James) passed away last October, but we will always cherish the values and the wisdom he brought to our community, our families, and to Prairie Hybrids. He
PAGE 1Prairie Hybrids
played a huge part in shaping Prairie Hybrids into what it is today. And, he always taught us by his example, saying… it’s “not always what I want to do, …but it’s what I need to do”. So, with Dad in mind, we keep focused on producing Quality, Pure, “Healthier” products, and always doing what we need to do.
Thank you for being our customer.
Sincerely,Gilbert Hostetler

PRAIRIE HYBRIDSREPLANT POLICY
If the stand of corn in a field originally planted to Prairie Hybrids corn is generally impaired, and it is desirable to destroy the stand and replant the field, Prairie Hybrids will furnish seed corn in adequate quantities to replant the field (or fields) for 50% of the retail base price, provided the original seed was purchased at our regular retail price, and that said field is replanted to corn during the same season. To take advantage of this offer, the farmer must notify Prairie Hybrids in time to permit inspection of the field by a Prairie Hybrids Representative BEFORE the original stand is destroyed.
PRAIRIE HYBRIDSRETURN POLICY
Prairie Hybrids will accept returned corn that was purchased for the 2018 season, provided bags are unopened and in SALEABLE CONDITION. No returns will be accepted after June 30, 2018. No returned corn will be accepted that was bought at clearance prices, or at a special discount.

GDU: WHAT IT MEANSGrowing Degree Units (GDU) is a way to rate the maturity of hybrids. It is based on the temperature required for a corn plant to reach physiological maturity. This is when the “black layer” has formed to the tip of the kernel, and the corn is safe from frost.This system will help you choose the best hybrids and maturities for your area. It will also help you estimate the maturity needed when planting is delayed. For example, if you plan to replant on May 25, and have 2350 GDU remaining until the average first killing frost, the hybrids can be selected on the basis of their GDU rating.
To figure growing degrees, the high and low temperatures are averaged for each day. Then subtract 50 degrees (the minimum temperature at which growth occurs in corn).
Temperatures below 50 degrees are always counted as 50 and those above 86 degrees are always counted as 86.
For example, on a day when the low is 48 degrees and the high is 90, GDU is determined as follows:GDU = 86 + 50 divided by 2 - 50 = 18
TIPS TO A HIGHER YIELDDear Customer,When you plant hybrid seed corn, it is critical to have adequate nutrition available to the corn plant, within the first 42 days, so it can produce an abundantly sized ear inside the corn plant. The most efficient way to accomplish this is with the planter. When you have good fertility, adequate moisture and cool nights, the corn plant has proven to yield abundantly for our customers.
The planter is one of the most important pieces of equipment on the farm. The planter settings can make or break a farm financially. If done correctly, the seed will emerge very evenly, which is the start to an abundant yield. We recommend planting 2 inches deep, when soil temps are 57 degrees and colder, or 2.25 inches deep, at 60 degrees and warmer…especially if planting after mid-May. Always error on the heavy side of packer wheel pressure. Correctly planted seed should all emerge evenly (within the same 12 hour period).
If you use chemicals, use pre-emerge chemicals all the time. It is best to avoid post emerge chemicals, if possible. If you do use post-emerge chemicals, spray before the 6th leaf or after the 9th leaf, if possible.
Wishing you an abundant harvest.
Sincerely, Gilbert Hostetler

This yield projection chart has been released from the University of Illinois. It has been modified slightly to take into consideration hybrids that have different ear types. Use this chart to know when to start planting, if you should replant, or if it’s too late to plant corn.
*Fixed Ear Type Hybrids: 3415, 5447, 6212, 6878.**Flex Ear Type Hybrids: 392, 418, 816,1663, 2607, 3074, 5879, 5787, 5200, 6903, 6158, 6950, 6407, 7204, 7355, 7387, 8052, 8229, 8904.
How to use this table:1. Enter the line that most closely represents the date your field was first planted. Read across the column until you are on line closest to the actual plant population remaining.
Example: If you planted 5447 (Fixed Ear Type Hybrid) on April 10 and 15,000 plants per acre remain, expect a yield of approximately 76% of full potential.
2. Enter the line representing the date closest to replanting. Read opposite your population goal. Example: May 24 planting, 30,000 plant population, 86% of potential yield.
3. Calculate net yield by subtracting yield potential from yield potential if replanted.
4. Determine if any yield advantage can be gained by replanting. Also, subtract the added cost of replanting (labor, fuel, chemicals, seed) and consider potential risks involved with replanting of a field.

ESTIMATING CORN YIELDSPRIOR TO HARVEST
There are several techniques for estimating corn grain yield prior to harvest. This version was developed by the Ag. Engineering Department at the University of Illinois, and is the one most commonly used. A numerical constant for kernel weight is figured into the equation, in order to calculate grain yield. Since weight per kernel will vary, depending on hybrid and environment, the yield equation should only be used to estimate relative grain yield. For example, yield will be overestimated in a year with poor grain fill conditions, while it will be underestimated in a year with good grain fill conditions.
Step 1. Count the number of harvestable ears per 1/1000th acreStep 2. Count the number of kernel rows per ear on every fifth ear. Calculate the average.Step 3. Count the number of kernels per row on each of the same ears, but do not count kernels on either the butt or tip that are less than half-size. Calculate the average.Step 4. Yield (bushels per acre) equals: (ear #) x (avg. row #) x (krnl #) /90
LENGTH OF ROW EQUAL TO 1/1000TH ACRE
An accurate estimate of plant population per acre can be obtained by counting the number of plants on a length of row equal to 1/1000 of an acre. Make at least three counts in separate sections of the field, calculate the average of these samples, then multiply this number by one thousand (1,000).
Length of single row toRow width equals 1/1000th of an acre

MEASURING HARVEST LOSSES
Insects, disease, weather, machine settings or operation, and other factors can cause grain losses that cannot be recovered with mechanical harvesting equipment. These rules of thumb may be helpful in estimating the significance of these losses:
Ear CornEvery large ear (0.7 lb.) per 1/100 acre equals about one bushel per acre. Four half-pound ears per 1/100 acre equal about 3 bushels per acre.
Shelled CornAn average of 2 kernels per square foot equals about one bushel per acre. Make several counts at various locations.
SoybeansAn average of 4 beans per square foot equals about one bushel per acre. Make several counts. Be sure to count beans left in pools below cutter bar level.
Grain SorghumAn average of 17 kernels per square foot equals about one bushel per acre. Make several counts at various locations.
