Seeding rates are important when drilling wheat!

Sandra Wick, Crop Production Agent


Producers are or soon will be planting their 2019 wheat crop, so stay tuned for some guidelines to remember when drilling your wheat. Variety selection is one of the most challenging decisions that needs to be made, but you need to remember that the wheat seeding rate is also a very important component to establishing your wheat crop. Recommendations in Kansas are often stated in terms of pounds or seeds per acre, and vary according to different precipitation zones. However, seed size can also have an impact in the final number of seeds actually planted per acre. A variety with larger kernels or less seeds/lb., when planted according to pounds per acre recommendations, will result in fewer seeds planted per acre and thinner stands than a variety with smaller kernels. So if the weather and fertility during the growing season are NOT favorable for tiller formation and survival, grain yields may be reduced due to the thinner stand. On the other extreme, a variety with small kernels planted according to pounds per acre recommendations can result in above-optimal stand establishment, therefore increasing competition for available resources such as water and nutrients.

So an advantage of planting wheat in terms of seeds per acre rather than pounds per acre is that seed costs can be reduced for varieties with a small kernel size. Seed size can simply be measured in terms of the number of seeds per pound. The “normal” range is about 14,000-16,000 seeds per pound for most wheat varieties, but it can range from 10,000 seeds per pound to more than 18,000 seeds per pound. K-State Research and Extension studies have shown that wheat variety plays a major role in determining wheat kernel size, as does the quality of your seed cleaning. So seed cleaning is very important if you are keeping and planting your own seed. This will ensure the final amount of seeds planted per acre will be close to your original target.

Certified seed, or seed submitted for germination testing, will provide for you the seeds/pound. The 2019 Wheat Varieties book for KS and the Great Plains also provides a reference to the seed size tendency of specific varieties. However, an easy on-farm method to estimate the average seed weight is to collect several representative 100-seed samples and the weight of each of those samples in grams. Then to calculate the seeds/lb., simply divide by a conversion factor and the average weight of the 100-seed samples. There is also a quick reference guide available to help you adjust the planting rate in pounds per acre based on the wheat variety seed size and the targeted number of seeds planted per acre. This is available at any of the Post Rock Extension District Offices in Beloit, Lincoln, Mankato, Osborne or Smith Center. The recommended wheat seeding rate for a dryland wheat producer in Central Kansas is about 750,000 to 900,000 seeds per acre, which calculates to about 50-60 lbs. with a final stand from 600,000 to 720,000 plants per acre. Then you simply use your seed size to increase or decrease the seeding rate along with your cropping system used and your planting date.

Lastly, with the recent warmer air temperatures, soil temperatures are also high. According to our KSU Mesonet, Weather Data Library, at our 3 weather stations in our PR district including JW, OB and MC counties, the avg. 2 and 4” soil depth temperatures over the past 7 days has averaged 76 degrees. Producers need to check the coleoptile length of wheat varieties which can affect your planting depth. Categories range from short to long so the planting depth should be adjusted accordingly as higher soil temperatures tend to shorten the coleoptile length so planting too deep can affect the germination of your seed. Call or stop by the Extension Office for a copy of the different coleoptile lengths of each of the wheat varieties. Contact me if you have further questions on wheat seeding rates at any Post Rock Extension District offices.

Fall Prevention Awareness Day

Ashley Svaty,  Nutrition, Food Safety and Health Agent 

One of the most important reasons that falls among older adults are so dangerous is the high risk of serious injury. The National Council on Aging has declared the first day of fall, Sept. 22 “Falls Prevention Awareness Day,” which aims to raise awareness about how to avoid these injuries.  A lot of those injuries can occur to the brain, so we have a high incidence level of traumatic brain injury,” said Erin Yelland, adult development and aging specialist for K-State Research and Extension. “Also, a large proportion of older adults who fall experience injuries to their bones - hip fractures, wrist fractures, fractures to elbows and knees.”
 
Yelland said injuries from falls could take months and sometimes years to get over, especially if those injuries require surgery, often followed by physical therapy and rehabilitation. Research has shown that a majority of the people who fall have a continued fear of falling.
Below are the 4 main items to consider to reduce falls:
Identify vision problems.
Seniors should visit their eye doctor at least once a year to make sure prescriptions are up to date, and to monitor for eye diseases or other problems.  If your glasses are not the correct prescription, your vision is going to be off which can lead to falls.
Make your home safer.
Installing devices in the home, such as grab bars, is a great safety precaution to prevent falls. These could be installed anywhere—along the walls of hallways, in the bathroom or next to the bed.

When older adults start to lose their balance and grow wary of falling, they tend to lean toward the wall and walk along the wall. If you’re in that stage, or you know someone who is, recommend that they install grab bars. So if they would fall, they could try their best to grab onto that bar and pull themselves back up to get to a telephone or to safety. The bars can also be a source of stability.

Assess your medications.
As people age, their doctors could place them on multiple medications. Seniors should visit their doctor and pharmacist to discuss their medicines and side effects.

If a side effect is dizziness or disorientation, perhaps there’s a different drug you can take that has the same benefits but has less side effects. Also, just being aware of what medicines you’re on and the side effects can prevent a lot of issues, including fall prevention, as older adults age.

Exercise to improve your strength, balance and mobility.
Exercise is a huge component of fall prevention, inactivity leads to weakness and an increased risk of falling. Through exercise that improves strength, balance and flexibility, we can increase the likelihood that our bodies are physically able to withstand a fall, help us recover from a fall, and more importantly, prevent falling. Also, with exercise often comes confidence and less fear of falling. Post Rock District offers Stay Strong, Stay Healthy strength training sessions in Jewell, Lincoln, Mitchell, Osborne, and Smith Counties.
