How to Use Multi-Year Yield Data Effectively

Posted By Latham Seeds Agronomy Team

Single-year data from corn test plots or even whole-field results can cause a farmer to question what hybrids to plant next spring. Because yields were especially variable across the Upper Midwest in 2020, I want to remind you how important it is to look at more than one year’s worth and more than one location’s worth of data.

Here are two ways you can use multi-year yield data effectively:

  1. Select individual hybrids that are consistently top performers.
  2. Look for groups of hybrids that, when planted together, provide top yield averages over time. In my experience, planting top-performing packages provides farmers with more uniform success. Planting packages of hybrids with top performance lessens variability.

Our 2020 plot data from F.I.R.S.T. Trials, on-farm SuperStrips with cooperating Latham® dealers, as well as our replicated MiniStrips proves again that Latham brand hybrids are top-yielding hybrids. Our wide area of testing shows very strong performance of Latham hybrids across various environments, soil types and management practices.

As I was preparing multi-year data to share during last month’s Post-Harvest Huddle meetings with Latham dealers, these top performers captured my attention. Be sure to take a closer look at these Latham brand hybrids as you finalize your 2021 crop plans:

  • LH 5725 VT2 PRO RIB: This 107-day product has the ability to move north as a full-season product. It performed well across the Southern Minnesota F.I.R.S.T. Trials locations. It has several multi-year F.I.R.S.T. Trial wins and top finishes from Nebraska, Iowa and Wisconsin. Plant this hybrid with LH 5245 VT2 PRO RIB, LH 5487 VT2 PRO RIB, LH 5635 VT2 PRO RIB, LH 5847 VT2 PRO RIB and LH 6285 VT2 PRO RIB for outstanding yield averages in different maturities.
