Multi-hybrid effort by Beck’s, Kinze becomes a reality
Since 2012, Beck’s Hybrids has been experimenting with multi-hybrid planting.
Jason Webster, director of Central Illinois Practical Farm Research, has done much of the hands-on work with this project. This year,the technology is commercially available. Through a partnership with Kinze Manufacturing, five Beck’s customers will plant with multi-hybrid planters.
By varying seed depending on soil type, Webster says Beck’s has seen a 9.5-bushel advantage in corn. The cost is about $2,000 per row extra compared to the traditional single-hybrid setup. That’s about $32,000 more for a 16-row planter.
Webster calculates the extra cost will be paid for with about 350 acres of corn and 400 acres of soybeans. And, yes, he has seen a yield advantage with beans also. In his testing, varying soybean varieties according to soil type resulted in a 3.5-bushel advantage.
The concept for multi-hybrid planting is fairly simple. The planter is loaded with two different hybrids: offensive and defensive. As the farmer drives across the field, the planter switches between the two hybrids depending on soil type.
Franklin, Ind., farmer Steve Long sums it up pretty well. “You tend to manage your poor ground differently,” he says. “I’d love to plant that racehorse hybrid, but I know it won’t do well on the majority of the acres in that field. Now I can put that racehorse hybrid on 5 acres in that 65-acre field.”
According to Webster, growers are making two key decisions when selecting hybrids. First is the genetic package. Using a Beck’s seed guide, the sales rep and farmer can tailor hybrids to specific fields.
The next big decision is planting population, which is evaluated while considering determinate vs. indeterminate (or fixed vs. flex) ears. In Webster’s testing, flex ears have worked best on poorer soils. On these soils, he keeps populations lower due to a higher degree of stress potential. If growing conditions are good, the flex ears can make up for the lower number of plants by putting on bigger ears.
On better soil, he pushes populations higher with a fixed-ear hybrid. These tend to have a taller, narrower structure. The better soil should allow more of these plants to flourish in a tighter space.
In late March, Beck’s flew a group of farmers to Temple, Texas, to get some hands-on experience prior to the start of planting season. Everyone in the group had purchased the Kinze planter.
In the previous concept-testing phase, Webster modified a Kinze twin-row planter to plant multiple hybrids in one pass. That setup resulted in a wavy row when the planter switched hybrids and the autosteer brought it back to center.
With the new models, each row unit features two electric seed meters, which share a single seed tube. Now, the switch between hybrids is seamless.
One of the primary concerns among the group was the ability of the planter to switch between multi-hybrid mode (which requires a preloaded job) and manual mode. That concern was put to rest when Webster explained that, yes, the Kinze 4900 can be run as a traditional planter.
After a few turns in the tractor, Jim Case was ready to take the technology back home to his farm in Delaware, Ohio. Case remembers hearing Webster talk about his multi-hybrid study a couple of years ago. It made a lot of sense to Case, who has four to five different soil types in the same field.
“Before this came along, we were trying to pick one hybrid as a best fit for all those different soil types,” he explains.
This year, Case needed to update his planter. When his name was selected for a multi-hybrid Kinze 4900, he was more than willing to pay the extra $2,000 per row. On corn, he’ll vary four different hybrids across his fields this year. He also plans to plant two soybean varieties.
