In farming and a pandemic – having the right denominator matters
The age-old agronomy equation is, "Yield Equals Genetics (G) by Environment (E) by Management (M)." There is a lot of focus on using data to measure hybrid and variety performance, in other words, to sort out the "G" part of the equation. That can start with your own data and but it can also include being part of "group, pooled or community" data. This allows you to anonymously see yield results from both genetics you planted and didn't plant. Being able to filter results by rainfall, GDU's and soils helps to address the factors that make up the "E" factor and get closer to apples-to-apples comparisons.
Yield results are in and every plot or trial has an overall winner! Winning a plot isn't easy. Sometimes, luck is involved. Years ago, one of our customers measured the impact of "shading" in a plot. If your company's hybrid was placed next to taller hybrids, how much did being shaded by a taller hybrid affect yield in the outside rows that were shaded? They found the difference could range from 7.7 to 33 bu/acre penalty from being shaded! In some company's trials protocols, they discard the outside two rows and only count the results from the inside two rows.

Increasing return on investment for every input is clearly on the mind of every grower. They are in an economic squeeze, but that doesn't mean they won't invest more in crops. It does mean they are scrutinizing every dollar they spend. The current success measure now goes beyond yield increase to include which inputs offer better return on investment.
