L.E.A.P. Update

Field staking and early season notes are in full swing in the L.E.A.P. plots. We are currently taking notes on populations, non-viable plants, vigor and emergence. The team kicked off notes at Neligh, Nebraska then moved on to Bloomer, Wisconsin and Galesville, Wisconsin. We then moved on to Fairfax, Minnesota and Claremont, Minnesota, finishing for now at Colfax, North Dakota.

We took time off from note taking to travel to Pocahontas, Iowa on June 6th as we finally planted the last L.E.A.P. plot of the year! This plot, which includes later day hybrids, will be a good test to see how hybrids respond to later planting. After planting, we headed to Lake Preston, South Dakota to take early season notes.

To date, all 11 L.E.A.P. plots have been planted and we have completed early season notes at 7 of the 11 L.E.A.P. locations.

Here is a peek at our top products based on our early season notes:

Neligh, Nebraska

Lake Preston, South Dakota

Bloomer, Wisconsin  

Galesville, Wisconsin

Claremont, Minnesota

Fairfax, Minnesota

Colfax, North Dakota

All of these top products had great emergence and vigor scores. We will watch and see if these products show strong performance until harvest.

Watch Out!

European corn borer damage at Lake Preston, SD plotWhile taking our early season notes, we noticed damage from European corn borers. European corn borer larvae can feed on any above ground portion of corn plants. Before tasseling, young larvae feed deep inside the whorl on newly-developing leaves and cause a “shot hole” effect. As the corn plant matures and the leaves unfurl, the damage made from the corn borer larvae will now be “shot holes” in a perfect line.

Soil crusting at Fairfax, MN and Lake Preston, SD plotsWe also noted soil crusting at Fairfax, Minnesota and Lake Preston, South Dakota plot locations. When the top layer of the soil becomes hard or “crusts”, the corn seedling has a hard time breaking through the hard surface.

Corn emergence hindered by soil crustingAs a result, the corn seedling can become bent and twisted or “corkscrewed”. Sometimes, the seedling can unfurl below the crusted layer. Either way it affects emergence and your final plant stand.

Legend Elite Advancement Project (L.E.A.P.) is our proprietary, in-house research program. It validates data on hybrid genetic performance over time and agronomic placement. Our L.E.A.P. plots are used for product evaluation, selection, and positioning on the right soil type and in the right geography to consistently deliver high value products to growers. Since 2014, we've conducted 85,890 replicated corn trials across 68 locations. As a result of our rigorous testing, we advance only the elite hybrids into our line-up, averaging 19 new products per year out of the thousands we tested.
