7 Years of On-Farm Trials with DuPont Pioneer
This was our 7th year in a row working with Pioneer. We have irrigated sandy soils and are trying to raise ultra-high corn yields. In fact, we’re the only growers in our county to have posted a certified yield of 300 bu/acre.
Highlights of 2014 Trial
This year, we conducted a variable-rate planting trial. We planted 4 hybrids at 5 different populations: 18,000, 24,000, 30,000, 36,000 and 42,000 seeds per acre. Although 42,000 yielded higher, we found 36,000 was the sweet spot for our best acres.
We seed at variable rates, starting at 34,000 as our base and raising populations to 36,000 in good areas but dropping down in poor-yielding areas. We base plant population levels on yield maps, soil types, yield history and our knowledge of our fields.
Gaining Extra Service
I’m all for working with Pioneer on on-farm trials. They’re here working for you and helping you be more profitable. Who else will come out on a Sunday to help harvest a plot? When you plant a test plot with Pioneer, they are on your farm more often, offering another set of eyes. If they’re scouting a field and see a problem, they note it in EncircaSM services. I’m getting a lot of service from Pioneer in addition to the seed they provide.

Highlights of 2014 Trial
We set up some corn and soybean population trials to identify optimum levels. We planted corn at 4 different populations and soybeans at 3 different populations. I’m interested in knowing more about plant populations, so this was a good study for me to take part in. We planted corn at 30,000, 34,000, 38,000 and 42,000 seeds per acre. We tested soybeans at 140,000 and 180,000 with a smaller strip of 160,000.
Viewing More Population Trial Data
A major advantage was getting to see not only the data from my own farm but from other farms with similar plots. I got to look at more data on plant populations in our area than I would have otherwise. I’d suggest these Pioneer® GrowingPoint® agronomy trials could be valuable for other growers who want to learn more about how products perform in their fields and other fields under local conditions.
Why I participated in a Pioneer® GrowingPoint® Agronomy Trial
I like to see agronomy trials first hand on my own farm and observe how products respond. It took a little extra time at planting and at harvest to segregate the strips, but that was the only significant requirement. Pioneer researchers were in the plots throughout the summer, but I didn’t need to be there unless I wanted to.

Plant Population and Silage Quality Data Wanted
We haven’t seen a lot of data on plant populations and silage quality in our area. This trial was an opportunity to learn more about how hybrids perform in our own backyard. Local data carries a lot of weight.
Highlights of 2014 Trial
We tested plant populations of 24,000, 30,000, 36,000 and 42,000 seeds per acre. We’re also looking at starch levels and tonnage. The plant population that appears best for yields on our acres is 36,000 seeds per acre. It’s too early to tell if that’s the optimal level for our operation because the starch level data is still coming in. I’m anxious to see what that tells us.
The Advantages of Participating
It was absolutely worthwhile to take part. There’s a value to learning on your own ground. Sometimes it will solidify your opinion of a hybrid or it might make you question one. I’m not one to jump on the bandwagon of a new hybrid too soon. I try new products, but I want to see if they have potential before planting too many acres. These kinds of trials can help you make better decisions.
It’s not a major setback in time. Even though we had a challenging spring, with wet conditions at planting, we were able to get the trial in without much hassle. I wouldn’t be afraid to participate in another Pioneer® GrowingPoint® agronomy trial.
How Easy It Was to Set Up the Trial
When it all boiled down, it was very simple. Pioneer had the manpower to help set up the plots. They knew what they wanted to test, and the sales rep and agronomists were able to design the trial. With a little bit of communication, we got it planted fairly easily.

Testing Variable-Rate Irrigation
We took a look at variable-rate irrigation to try to determine if we could use our water more efficiently. I think variable-rate technology will be important for us in the future.
We found we could use less water on our better ground, more on our lighter soil and get better overall results. We saw yields increase by 10-15 bu/acre on average. Our fields contain extremely variable soils. Varying the amount of water we applied to different soil types made a huge difference. It was amazing.
The variability on our yield maps improved dramatically. We didn’t have so many large areas of greens and reds. It really helped level our yields within a field.
We’ll continue to look at variable-rate irrigation in the future. In 2013, we had average to slightly-above-average rainfall. I would expect varying irrigation might have even more impact in a drier year.
Working with Pioneer
Taking part in these trials was a great learning experience. We had access to lots of good data and gained a lot of knowledge that will make us more efficient in our water use. It takes a bit of time to participate, but Pioneer guys did a lot of the work. They were available by phone and out here any time we needed them.
