CropWatch: Your Place for Reliable Crops Information


CropWatch is written by Nebraska Extension specialists and educators from across Nebraska to provide timely, research-based information to help you make your farm decisions. During pesticide education sessions and other programs, I remind producers about the vast amount of resources available. We continue to reach more people each year, but we still have many producers that are not checking it on a regular basis.  I hope you’ll all make it a goal or resolution to do so in 2018!  Just a sample of some CropWatch information I included in this week’s column.

Nebraska Crop Budgetsmoney bag
The Nebraska Crop Budgets have been updated for 2018 costs and conditions, and include five new budgets relative to corn-soybean rotations. In total, there are 78 crop production budgets for 15 crops, as well as information on crop budgeting procedures, machinery operation and ownership costs, material and service prices, and a crop budget production cost summary. The 2018 crop budgets are available at

NE Extension Successful Farmer Series
The Nebraska Extension Successful Farmer Series returns January 5 with the first of six workshops to be held at the Lancaster Extension Educator Center in Lincoln.

These Friday morning workshops, held from 9 to 11:30 a.m., are organized by topic so individuals can zero in on the topic most pertinent to their needs, he said.

The cost is $5 for each session or $15 to attend all six. Handouts and materials will be provided at each workshop and CCA credits will be available. For more information, see the program brochure. To preregister, call 402-441-7180. Refreshments will be provided.

Private Pesticide Applicator Trainings
Private pesticide applicators holding licenses that expire in 2018, as well as anyone seeking first-time private applicator certification, can contact the Extension office for information on pesticide safety education training sessions. About 200 statewide sessions will be held January-April. Letters to producers with a listing of the trainings should be in your mailbox soon if you need to recertify, but you can check the website for a complete listing.

Shorter than Normal Corn?

Crop ET Weekly Report
The ETgage I outside of Geneva changed 2.0 inches for the week of June 29 – July 6th. Corn in the reproductive stages has a coefficient of 1.1 inches so corn in the area used 2.2 inches or .31 inches per day.

Have you noticed shorter than normal corn?

One thing many have either noticed or heard is how unique this growing season is from most others. From various crop professionals to horticulturists, this year has definitely been different from other years I’ve experienced since in Extension with plants progressed earlier than normal. It has also been a drier than in recent years. With that in mind, I’ve had several questions which were recently addressed on UNL Extension’s CropWatch website which I’m summarizing below.

In many areas of the state we’re seeing shorter than normal corn this year, leading to the question, “Why this year?” To explain this, Keith Glewen, UNL Extension consulted with two top corn physiology experts — Bob Nielsen, extension corn specialist at Purdue University, and Tom Hoegemeyer, professor of practice in the UNL Department of Agronomy and Horticulture. His CropWatch article depicts the following information.

Nielsen and Hoegemeyer explain that a variety of interacting factors can lead to shorter than normal corn. First, let’s look at this corn crop to date. We planted most of the crop much earlier than normal, which led to corn plants developing during a period when in most years, the seed would still be in the bag. After planting, we experienced warm daytime growing conditions and cool, almost cold nighttime temperatures.

The mature corn plant height depends on three factors: amount of solar radiation on the top leaves during growth, water, and temperature. We usually don’t have issues with solar radiation limitations in the western Corn Belt; this year water was more of a factor. Much of the young corn plant’s development was in drier than normal growing conditions. There was adequate moisture for growth but nothing like we have experienced in recent years.

Water availability and temperature impact growth rate. Cell division is affected much less than cell expansion, and slower growth rates lead to slower root development, further limiting water uptake and nutrients. Slower cell expansion leads to shorter internodes and smaller leaves, and this leads to less water uptake and light interception, CO2 uptake, further impacting growth. Because of these changes, we have less internode elongation and thus early planted corn tends to be shorter than later planted corn.

Will conditions leading to shorter corn impact yield? Not necessarily. More important to the final yield of this year’s crop is the heat and moisture stress that the crop is now experiencing as it moves into pollination.  With the high heat we experienced this week, it will be a concern.

Fillmore County Fair

Fillmore County 4-Her’s will be showcasing their projects July 14-19th at the Fillmore County Fair.  As we prepare for this event, it is important to emphasize that 4-H youth are more important than 4-H projects, learning how to do a project is more important than the project itself, competition is a natural human trait and should be recognized as such in 4-H work; it should be given no more emphasis than other 4-H fundamentals. And one of my favorite points is that, “a blue ribbon 4-H’er with a red ribbon entry is more desirable than a red ribbon 4-H’er with a blue ribbon entry.”

Come and support 4-H’ers with fair activities as listed below:
