Stu Duncan – Soybean Management Practices

(Conrad) Good morning and welcome to Farm Factor on AGam in Kansas. I’m your host, Conrad Kabus. Soybean schools were held in February of 2015 to provide in depth training targeted for soybean producers from Kansas State and other professionals giving workshops. Stu Duncan gave a workshop on increasing acreage in the central part of the state and beyond. (Stu) I was…this morning I was presenting at our soybean school, the first of our four that we’re having statewide this week. My presentation here, well to Salina we’re covering as many aspects of intense soybean production as we can. Our acreage has grown so dramatically in the central part of the state as I look back 12 years ago to the beans or more were planted east of the Flint Hills. Now, it’s the central part of the state is picking up over 40 percent of the state acreage now, from south to north. It really has grown in the central part of the state and that’s why I think it’s very important that we were here at Salina. We’ll be in Derby tomorrow, Independence on Thursday and then up in Sabetha, up in the northeast corner on Friday. (Conrad) Soybean yields are affected by many factors, some of which were introduced in the workshop in Salina The psychological characteristics provide insights for unusually high soybean yields. Responsible management practices create a unique maximum yield and of course, weather conditions. These and more are ones that producers need to watch for. (???) What my presentation involved was the soybean production management. The aspects of what the farmers can do to produce a high yielding, viable crop. Still very restricted by the weather, but most… our Kansas data and data from results from surrounding states, which show that planting date weed control, making sure we’ve got enough seeds out there. And my presentation was more of a general one but planting date and row width are probably our two biggest factors, at least in the central part of the state depending upon your yield environment. When you’re at a higher yielding environment and I would call that 50 bushel plus potential, you could incorporate a few more practices, a few more tweaks into the system. In the 25 to 40 or 50 bushel yield environment, still I think row spacing can make a big difference especially here in the central part of the state where we have a lot of heat and unless it’s irrigated and I’m talking pretty much dry land. If you’re on an irrigated site I certainly would go with a 15 inch or narrower row if I had the capabilities to do that. Narrower row spacing will just allow that canopy to form quicker which will save water and keep the canopy cooler when it’s in those critical flowering times. And in central Kansas as in most of Kansas, in a dryland situation you can do that alright and it still gets…when we hit our very hot temperatures at peak flowering times we still can have issues with pod set. Cause what we want is as many nodes on that plant because that equals more flowering sites, which equals potentially more pod sights gives us potentially more pods and then more beans per acre.
