Wheat Management Research

(Romulo Lollato) Hi! I’m Romulo Lollato, Extension Wheat Specialist with Kansas State University. Today we are here in the South Central Experiment Field just southwest of Hutchinson. We’re going to discuss a few of the projects that we have going on here with you today. The one that we’re standing at right here is what we’re calling an intensive wheat management trial. This is a trial that is being funded by Kansas Wheat Commission and also DuPont is helping cover some of the cost. In this trial, what we’re looking at is whether intensifying wheat management is going to pay off in your profitability in the end of your wheat crop season. Here, we are looking at a few different things. In one side, we have what we call our standard management practices where we’re keeping weeds under control so that’s not a leading factor. And really the only management practices that we’re coming back with in the growing season is a nitrogen fertilization for a new goal of about 70 bushels per acre. On the other extreme, we have what we call our intensive wheat management where we’re looking at not only a split nitrogen application during the spring but also a couple of fungicide applications, growth regulator and some other factors that have proved which increased wheat production in a few scenario such as chloride, sulfur and increased plant population. So we’re testing a few different factors here. In between these two extremes, we have an individual addition of each factor to our standard management. For example, our standard management with the nitrogen application during spring plus the fungicide application. Second treatment, we, our standard management plus just our sulfur application and so on. Versus on the other side, individual removal of each factor from our very intensive management. So our full intensive management minus our growth regulator. How is that going to affect it? Our full intensive management of only one nitrogen application rather than a split nitrogen application. Really, our intention here is to see if intensifying wheat production is going to pay off, not only increasing yields, because this we would expect it should increase, but also in your profitability. That’s what matters in the end of the growing season is whether you’re making more money or not out of your wheat crop. That’s what we’re looking at here. Whether intensifying wheat production will pay off or not. Later on, we’re going also to work with Becky Miller at Kansas State University and take this to a quality test. How is our management affecting the quality of the wheat coming out of your field? The variety that we’re using here is Everest. It’s a very susceptible variety. In a year like the one that we’d be having this year, the treatments that we have — we’ve had a fungicide application — are really showing up. We have here stripe rust that was a very big problem here this last few weeks. We’re all just starting to see leaf rust which is a problem towards more at the end of the growing season. Differences are really showing up not only on the fungicide treatment this growing season but also growth regulator and many other treatments. We’ll wait and see how yields going to come out of this, profitability and bringing you this very applied information. You can follow me on Twitter @KSUWheat or on Facebook, K-State Wheat and be aware of the Agronomy eUpdates that we send on a weekly basis. We follow that information for you.
