For the past ten years I’ve come across farmers who really believed in applications of sugar to reduce their pest populations. Being no research to my knowledge to prove it, I tucked the observation in the back of my head for future reference. With farmers looking to increase yields and looking to other farmers such as Kip Cullers for information, some of our on-farm research producers were curious about sugar applications in their operations with the hopes of increasing yield.
Nebraska On-Farm Research Corn Results
Using the application rates that Kip Cullers uses, one Clay County producer applied 3 lbs of sugar (purchased pallet of cane or beet sugar from the local grocery store) per 10 gallons of water at V7-V8 on corn in 2010-2011. Cullers also tanked mixed the sugar solution with a post-herbicide application like glyphosate but this producer didn’t do that. To simulate any affect of the water or driving through the field, he also drove through the untreated check spraying water only. Two years of research results showed no significant increase in yield. However, there was a noticeable difference in standability at harvest. This producer did not apply a foliar fungicide either year. When it came to harvest, this producer needed the reel in 2010 for the untreated check. Stalk rot ratings were taken using the pinch test two weeks prior to harvest. To him, the $1.25/acre of sugar was worth it to improve standability even if yield was not significantly improved. You can view the full research report here.
Several York County producers have also tried this with one producer finding a non-statistical 2 bu/ac yield difference with the check yielding better while the other producers found a statisically significant 2 bu/ac increase to the sugar treatment. Another producer in Hamilton County is testing this using the corn product he grows-using 1 qt of corn sugar (high fructose corn syrup) per 10 gal of water applied still at V7-v8.
In 2012, a small plot study was conducted at UNL’s South Central Ag Lab near Clay Center to determine any differences between sugar application, fungicide application, and untreated check in corn. All treatments were applied at R2. Because of the drought in 2012, there was minimal disease pressure, thus there were no significant differences between the three treatments regarding area under the disease progress curve. The untreated check did show the most stalk rot (via the push lodging test). The sugar application reduced the lodging rating by half and the fungicide application showed the lowest lodging rating. For yield, there were no significant yield differences with the untreated check yielding the highest followed by the fungicide and sugar applications. The entire study report can be found here.
In Soybeans we have had producers apply 3 lbs sugar in 10 gallons of water at R3 (beginning pod). In all years, there have been no significant differences in yield. Lodging ratings were not taken as that is more variety and water dependent.
has shown that application of sugar to crops increases the numbers of beneficial insects in those fields. South Dakota research entomologists showed that lady beetles benefited from a combination of prey and non-prey foods. In a follow-up study, these entomologists applied sugar sprays to soybeans and quantified the frequency of sugar feeding by analyzing the gut contents of common lady beetles in three states. They found all the tested lady beetles regularly consumed sugar-like nectar in soybean fields, even when it wasn’t applied as a supplement. They also found more lady beetles in the sugar treated plots compared to the untreated plots.
At this time we can’t explain the standability effect we’re seeing from our sugar applications to corn. Our hypothesis is that early application of sugar to corn is increasing beneficial microbes that may be keeping the exposed brace roots and stalks healthier. We hope to conduct more research in the future to answer this question.
the application of sugar to corn and soybeans has not always shown increased yield. However, in nearly all of the corn studies, sugar treated plots have shown increased stalk strength at harvest. Research has also shown an increase in the number of beneficial insects in fields where sugar was applied. Further research is needed to understand the interactions aiding stalk strength in corn.

What do you think of sugar applications to crops? Have you tried this in the past and if so, what were your results?
Even with recent rain and snow events, the subsoil is still dry. You may be wondering,
“What should I do regarding corn planting rates in 2013?”
A few weeks ago, UNL Extension held our on-farm research meetings to share our 2012 Corn Planting Rate results for irrigated and dryland conditions. I always enjoy hearing our farmers share why they were interested in a certain trial and what they found out as a result.
The results since 2010 continue to show us that each individual hybrid varies in its response to increasing populations; however, there is a general trend with newer hybrids that increasing population results in increased yields. Dr. Tom Hoegemeyer, UNL Agronomy Professor of Practice spoke about how our hybrids have genetically come so far in combating various stresses while maintaining yields. We know that many seed companies have conducted research to determine the population calibration curve for each hybrid to determine best recommendations for you. Thus, we’d recommend that you check with your seed dealer to determine which hybrid may fit best at which population for your operation.
Even with this data, you may question if that’s truly the best population for your field; that’s where on-farm research comes in! We recommend testing the recommended population against a higher and lower population with at least 4000 seeds/acre difference in planted population-whether irrigated or dryland. With today’s technologies, it’s not very difficult to test seeding rates for different hybrids for yourself!
So what rate should you plant this year? In the majority of our irrigated studies, economically, many hybrids maximized yields and economic returns between 32,000-36,0o0 seeds/acre. Again, this is very hybrid dependent so ask your seed dealer what he/she would recommend and test for yourself!
Regarding limited irrigation, UNL research has actually shown a negative effect of lost yield by backing off population too far in a dry year.
Tom’s recommendation was for dryland in Eastern Nebraska, most hybrids even with the low soil moisture profile should be ok with planting 24,000-28,000 seeds/acre. I realize we have essentially no moisture in our profile. But taking probabilities of rainfall events, March-May is usually pretty good and we don’t want to short-change ourselves in yield by planting too low of populations. For Central into Western, NE, I feel 20,000-22,000 seeds/acre will work for many hybrids. Our genetics have come so far since we finished the last drought in 2007 and were planting 18,000 seeds/acre in dryland. We will just keep praying for rain and hope for the best next year! Ultimately, test this and your other on-farm questions for yourself to know what will work for your farm!
What planting rates are you considering for 2013?
Today the Nebraska National Guard Agribusiness Development Team 3 (NE ADT3) would be reunited with their families! I found myself going back 10 months ago to the day after Memorial Day 2012. That was the day several of us were reunited with our soldiers and airmen from NE ADT2.
Today I was remembering bouncing up and down while holding hands with other military spouses watching the bus with our military members pull up. I remember seeing my husband get off the bus and running to his arms. I remember that even amidst all the family members and friends gathered that day, the military members were always gravitating towards each other-looking for each other. Sure, they were excited to be home too….but their best friends….their battle buddies who they’d spent the past year with was who they felt most comfortable with at that moment.
I remember how tired they all were-how they all just wanted to go home…and yet how quickly they all missed each other. I remember so many things being overwhelming to my husband…crowds of people and everyone asking him the same questions, going to Golden Corral after we left the welcome-home event and him being overwhelmed by the amount of food available to eat (he ended up eating very little), going to a grocery store where we have such a variety of EVERYTHING and having so many choices…
We truly are so blessed in the U.S.A. and take these blessings for granted everyday!
As I drove to the welcome home ceremony today, I thought back on this post and how I left many of you hanging about what happened next. Honestly, I’ve started many draft posts but struggled to know what to write or really what to share.
Many think that once our military members return that all is right in our world. But the reality is that while there’s a honeymoon period, there’s also a great deal of hard work to make reintegration occur. You see, military members and their families have been living in two different worlds the past year. My husband and his comrades were living in similar to Biblical times working with great people but yet always had to be on guard for the enemy. I was living in a fast-paced techno-savvy world trying to hold everything together here. We both were fortunately forming bonds with military buddies and spouses that will last a lifetime. I was safe at home with my dogs. He and some of his comrades had close calls with death.
I will never know…
what it was like for him to leave home and everyone he loved to serve a Country that he loves and was willing to lay his life down for. To work as hard as he could so he could go to bed exhausted in hopes of not missing the home he loved so much. He will never know what it’s like on this end…to have everything in our home remind me of him, to spend endless nights and go to countless events alone, to hold my breath at every bit of news I hear from overseas, and to continually say silent prayers throughout the day for all our military members and their families. But these are the sacrifices military members and their families are willing to make to defend the cause of freedom. We love this Nation and are so proud of and thankful for those who are willing to defend her!
Since the deployment, I learned that it was hard for him to want to connect with home and me. His coping strategy was to not connect so he could focus on the mission and not think about home or worry about how things were going here. (He now would never recommend this strategy to any military member!) My coping strategy was to send him letters and packages-to show him he was loved and missed. But lack of communication is hard on a marriage and it takes time to re-build that. I would say for many military couples, reintegration is even harder than the deployment and separations themselves. We all have good intentions for a good reintegration…we learn what to watch for and have resources available to help…but the reality is that we’ve been going two different directions for a period of time. It takes work to bring those lives back into the same direction again. But it’s worth the effort!
One way that helped us get away and start communicating again was to attend a Family Life Weekend to Remember Event. There are discount rates for military members and their spouses and there are special locations where there are military emphasis breakout sessions for military couples to talk about military specific issues such as deployments, separations, addictions, etc. It really helped us to start that conversation again and I would encourage any married couple to attend one!
I smile everytime…
I see my husband going through his Afghanistan pictures with the sweetest smile on his face. I know he misses it…he misses the daily work with his buddies and the difference they were making in the Afghan people’s lives. My husband took lots of pictures and video with his helmet cam. As he shared his stories, I realized how much I take for granted. His buddies and us wives have also often gotten together as the guys have spoken at various events. Those are good things-things I will continue to encourage.
I’m so thankful God allowed my husband to be on that deployment with great leadership and friendships. I know he’d go back in a heartbeat-especially if he could go with the same people he served with. I think of these Agribusiness Development Teams’ mission to provide for a sustainable Afghanistan…to teach the people how to feed themselves and provide for their families…of the successes that have been achieved. I’m praying for a sustainable Afghanistan and hope that one day-maybe in 10 years-my husband and I can both go and see the places he was, meet the people, and hear the stories of how their lives were changed as a result of our brave men and women serving.

I would encourage any farmers, spouses, and adult children to consider attending this Farmers and Ranchers Program! Communication and fair transition plans are keys to keeping family ties and the family farm strong. I’ve watched too often where communication doesn’t occur-even most recently with my extended family-and the heartache caused as a result. Work on the communication and transition plan now before it’s too late!
The final Farmers & Ranchers College program for the 2012-13 programming year will be held on March 14, 2013 starting at 6:00 p.m. with a meal and the program to follow. It will be held at Evening with Friends Restaurant in Milligan and will feature Dr. Ron Hanson, Neal E. Harlan Professor of Agribusiness, Ag Economics Dept., UNL. A description of Hanson’s program is provided below.
The entire process for mapping out a succession plan to transfer the eventual ownership of a family farm from one generation (parents) to the next generation (their adult children) can be an overwhelming task for many families. Where does this process even begin? Who makes the final decisions? Can you be fair to everyone involved? What if there is not good communications within the family? How do you keep emotions and personal jealousies from taking over and preventing good decision making? These…
