Sevie Kenyon: Looking at some new corn hybrid technology we’re visiting today with Joe Lauer, Department of Agronomy, University of Wisconsin-Madison/Extension in the College of Agricultural and Life Sciences and I’m Sevie Kenyon. Joe, what are you seeing that is new in these corn hybrids this season?

Joe Lauer: Well last year we saw for the first time a brand new transgenic trait that has a lot of potential, it’s called DroughtGard. We had it in 11 different hybrids this past year and three of them were star, which means that they were not statistically different from the top yielding hybrid in a trial. And that’s always a good sign that a trait is off to a good start on performing well. This particular trait is what I would call more like a yield enhancing trait than the traits we currently have available to us. The ones we have available are what I call yield protecting traits, things that we can control insects with, control weeds with more easily. They don’t necessarily add to yield but they allow us to keep some of the pests that corn plants commonly encounter at bay a little bit better. Continue reading

Sevie Kenyon: The environmentally friendly cow, we’re visiting today with Randy Shaver, Department of Dairy Science, University of Wisconsin – Madison/Extension in the College of Agricultural and Life Sciences and I’m Sevie Kenyon. Randy, what makes an environmentally friendly cow?

Randy Shaver: Well, it’s one that we can minimize the amount of waste product that the cow excretes in the environment and talking a lot about nitrogen and phosphorus and these days even methane emissions. Continue reading
