Look at Multi-Year Soybean Yield Data

Yield variability in 2020 reminds us how important it is to review data from multiple years – and even multiple locations – when accessing a given seed product’s performance. Multi-year data helps “smooth out” the peaks and valleys associated with single-year data and provides a more reliable picture of overall product performance.

Following are nine Latham® soybean products, in order of maturity, that grabbed my attention as I was preparing for 2020 Post-Harvest Huddles with our dealers:

L 0852 LLGT27: New for 2021, this powerhouse yielder carries the Rps3-a gene for Phytophthora and has very good tolerance to iron deficiency chlorosis (IDC). This variety earned six Top 10 finishes in the 2020 F.I.R.S.T. trials; took first in 2019 Latham Test 909 Summary; placed first in our 2020 Test 960 trial at Glyndon, MN; and was 2nd overall in the 2020 Summary of Test 960!

L 1238 L: This top-yielding Ironclad™ soybean features excellent scores for both White Mold and Sudden Death Syndrome (SDS). It took 1st place in our 2018 Test 961 Summary and had four other 1st place finishes in Latham Trials from 2018 to 2020. It moves south very well out of zone.

L 1429 LLGT27: Here’s a great yielding line with a good defensive package! It has strong Soybean Cyst Nematode (SCN) tolerance and is excellent against IDC and Brown Stem Rot (BSR). In 2019 and 2020, it earned five Top 10 finishes in the F.I.R.S.T. trials along with four wins in Latham SuperStrip plots. It also placed 1st six times in our research trials, including two summaries!

L 1858 R2: This is one of the very highest performing lines in our Latham soybean portfolio. Every year since 2018 it has topped a F.I.R.S.T. Trials SUMMARY somewhere in the state of Minnesota! Enough said.

L 1883 L: This Ironclad line has excellent tolerance to White Mold and SDS with great tolerance to Charcoal Rot. It has six 1st place finishes under its belt from 2018 to 2020 SuperStrip trials. It consistently performs at the top of its class.

L 2193 E3: Our top-selling soybean for the past two years looks to be headed there again in 2021! With only two years of SuperStrip data, this Ironclad variety has claimed: eight 1st places, eight 2nd places and six 3rd place finishes. That’s a gold-worthy Win-Place-Show combo!

L 2295 R2X: With a very strong defensive package, this soybean variety is a proven performer! It has 22 Top 10 finishes in the F.I.R.S.T. Trials and 37 Top Four finishes in Latham SuperStrips – including 13 wins – during the past three years.

L 2549 R2X: If you think L 2295 is impressive, get a load of this offensive powerhouse! In the 2018 to 2020 F.I.R.S.T. Trials, 2549 captured 41 Top 10 placements with six of those being for 1st place and nine for 2nd place! It has also won five SuperStrip plots. It has L 2084 R2 and L 2440 R2 in its pedigree with a strong defensive package.

L 2894 E3: In its first year of F.I.R.S.T. Trials, this popular Enlist E3 line took 1st place twice and earned seven more Top 10 finishes. In 2019 to 2020, it took 1st in six SuperStrip plots and topped our Latham Research Trials in both Alexander and Olin, Iowa.
