Show Notes
In today's episode: Does corn really need to be so tall? It's time to explore this concept of reduced stature corn, otherwise commonly referred to as short corn. When you picture a mature cornfield, I imagine you're probably thinking of tall green stalks, towering overhead, and there are some agronomic advantages and disadvantages to this.
So some corn breeders are developing varieties that are intentionally shorter. One of those breeders is Dr. Sarah Lira, who you've already heard from on this show back on episode eight when she was talking about perennial ground cover.
“ And that's basically the system we're setting up for breeders with short corn, is that they can focus on selecting on yield and they can focus on selecting on yield in higher densities. So when you can plant the plants in a higher density, they're not going to get tall and fall over. So you can continue to select on yield more aggressively than we've ever been able to do before.” - Dr. Sara Lira
Sarah has also been working on some shorter corn varieties and this concept of reduced stature corn. It has a lot of farmers intrigued. Blake Johnson is one of those farmers. He's a fifth generation corn farmer in Nebraska.
“ Probably the most exciting thing that we've been looking at on the horizon that is not here yet is short statured corn, because when we're in the high yielding environment. We're wanting to push populations. A lot of times when you push that population, those plants are gonna fight in that competitive environment and actually get taller than they should.” - Blake Johnson
Some takeaways from this episode include:
The very real problem of lodging, which is creating real demand for reduced stature corn. The idea that reduced stature corn could actually have just as much plant residue as standard corn. It’s definitely interesting to get a glimpse into the research and development pipeline, and encouraging to hear of the first trait reaching the field in the coming years.

Corteva Agriscience chief technology and digital officer Sam Eathington and some really special guests discuss the past, present and future of agriscience innovation.
Dr. Carla Yerkes joins us to help us tell the story of Rinskor and explain the process of herbicide innovation and the persistence and creativity it takes to develop new solutions for farmers. Yerkes is a research biologist at Corteva Agriscience and has a Ph.D. in herbicide physiology. She has spent about half of her 30 year career in herbicide discovery research and the other half in herbicide trait discovery.
What is happening in agriscience today that we will be talking about 100 years from now? While it’s impossible to answer that question with certainty, there is a technology that has the potential to impact our industry in the next century as much or even more than hybridization changed the game over the past century. That technology is genome editing. The promise of this technology is very real and today you’re going to hear firsthand accounts of what changed in 2012 and 2013 to make all of this possible, what did it look like to test the technology in plant breeding, and what does the strategy look like to turn this science into better solutions.
In today’s episode, we’re following a molecule around the world, from being discovered in Japan to being developed in the United States to becoming a solution for farmers in the United Kingdom. Joining us is one of those farmers in the UK, Julian Gibbons. Julian has seen a variety of fungicide solutions come and go for important wheat diseases like Septoria tritici, or speckled leaf blotch. He’s really excited about the potential for a relatively newly registered product derived from a natural compound called Inatreq Active™. And the story of the need for Inatreq and the road to getting this product to farmers is the focus of today’s episode.
We celebrate the 100th year anniversary of Pioneer Seeds, and take a look back at the history of hybridization. The process may seem simple: to take two varieties or even species and cross them together to create more desirable offspring. But the concept of controlled hybridization, intentionally transferring pollen from a chosen male parent to a chosen female parent, is relatively new in the history of agriculture. But it has been nothing short of revolutionary.
