Greg Akagi: This is the Kansas Soybean Update. It’s brought to you by the Kansas Soybean Commission. The Soybean Checkoff Progress Powered by Kansas Farmers. Ignacio Ciampitti, Associate Professor in cropping system specialist at Kansas State University joins us. Ignacio, you’ve been conducting ongoing research looking at the potential impact of improving soybean yields by seed filling. What are some of the objectives of the research and what have been some of your findings?
Ignacio Ciampitti: We were looking at different options. We know that many farmers are usually focused on early-season management and usually they focus on practices, how they will impact the crop early in the season but we know that close to 50% of the yield is usually defined late in the season. Usually, is defined, well, in the clear that we call the seed filling for soybeans. Thinking on that situation, we know that protecting the canopy and the plant health at the end of the growing season is a key factor for soybeans. We propose a project that we are looking at different management practices, for example, application of fungicide, insecticide, adding nutrients, and looking at different management so we can find ways of boosting up the yields and protecting the canopy.
So far, what we are finding is that extending the duration of the greenness, the time where the plant still can be productive is one of the key factors for securing in some situations between three to four bushels extra. Then that would be one of the best-case scenarios in the sense of increasing yield but we also emphasize in the point that in many situations we’re protecting yield.
Greg: Ignacio this type of research is not possible without funding from the Kansas Soybean Commission.
Ignacio: Yes, the entire funding on this project was coming from Kansas Soybean Commission. Then the main point of emphasis is that we are also looking at basically the frontier on the knowledge because most of the research has been done in the past was only focused on early-season or practices that were around mid-season. We are really looking and trying to understand, can we impact yields or maintain yields by just adding extra management towards the end of the season, which at the moment that we know that we usually define really high proportion of the yields because seed weight is just one of the main factors and main component contributing to yield on soybeans.
Greg: Ignacio, we appreciate your time. Thank you very much.
Ignacio: Thanks, Greg.
