What does it take to break the world soybean yield record? Today we talk to soybean yield record-holder Alex Harrell and soybean breeder Don Kyle. Alex farms in southwest Georgia with his dad where they primarily grow soybeans, corn, wheat and watermelon. In 2023, he became the first farmer to record a soybean yield of over 200 bushels per acre. The next year he beat his own record coming in at 218.2856 bushels per acre. It’s an incredible achievement for anyone, but it’s even more impressive when you consider that Alex farms in an area that doesn’t generally grow a lot of soybeans. 

“ We did a lot of studying, a lot of class, made a lot of mistakes, and watched a lot of beans rot in our humidity. You know when the things do line up, we have a lot of yield potential there as well. ” - Alex Harrell

Farmers like Alex have had to learn these lessons and refine their system over years while experimenting with and matching up the right genetics for their fields. Don Kyle became interested in soybean breeding in the early 90s and has since dedicated his career in plant breeding to the crop. Today he’s a soybean breeder and Evaluation Zone Lead for the Eastern US at Corteva Agriscience based in Princeton, Illinois. He says even though he’s focused on soybeans for over 30 years, he’s more passionate than ever about the crop. Don thinks we might see more hybrid soybeans in the future, similar to what we’re currently seeing with wheat. But for now, farmers aren’t using hybrid soybeans so it’s even more impressive what farmers like Alex Harrell have been able to achieve in terms of yield growth over the years. 

“ It's very easy to produce soybean seed because they self-pollinate themselves. The problem is to produce hybrid seed is really difficult. So making a cross between two different soybean varieties today still requires using tweezers and sometimes magnifying glasses so you could see the flower parts the best. It's a very tedious job.” - Don Kyle

A few takeaways from this episode: 

1. Incredible yield growth is possible without hybrids in soybeans
2. The significance of detailed management allows for more precise practices that create the best yields
3. Successful genetics is more about varieties with resilience rather than yield magic to account for the many factors that can’t be controlled
