  1. Double Crop Soybean Recommendations

    Author(s): Laura Lindsey

    As small grains are harvested across the state, here are some management considerations for double-crop soybean production:

  2. Soybean Vegetative Growth Stages- VC vs V1

    Author(s): Laura Lindsey

    Across the state, soybean growth and development is variable, ranging from early vegetative stages to flowering. However, there has been some confusion regarding the identification of the VC and V1 growth stages. This confusion is mostly due to two definitions of V1…that actually mean the same thing. The Fehr and Caviness Method (1977) is based on the number of nodes that have a fully developed leaf, whereas Pederson (2009) focuses more on leaf unrolling so that the leaf edges are no longer touching.

  5. Dragline application of manure to growing soybeans

    Author(s): Jason Hartschuh, CCA , Author(s): Glen Arnold, CCA

    As we continue to search for profitable ways to expand the manure application window in Ohio, we have begun to research dragline application of manure to growing soybeans. While this would potentially open up more time for manure application in the spring, our initial research goal is to look at the ability to apply manure to emerged double crop soybeans after wheat. For many years, livestock producers have successfully applied liquid manure to newly planted soybeans in July to help provide moisture for germination and emergence.

    Sampling for Soybean Cyst Nematode – Fall is the time!

    Author(s): Anne Dorrance

    As we wait another week for the fields to dry out, this provides some time to sample soil for the SCN populations.  The SCN Coalition theme for the next few years is What’s your number?  Do you know where SCN is in your fields and what the current population is sitting at?  If its high, then there is a second number – what is the SCN type?  Which addresses the bigger question can it reproduce on the SCN resistance source PI 88788 or Peking.  All of these numbers can impact management of this root pathogen and future losses.

  10. Seed Quality Issues in Soybean

    Author(s): Anne Dorrance

    Let’s face it – we’ve had historic rains in parts of Ohio during 2018 and we are now observing many late season issues that come with this.  Seed quality is one of them and the symptoms or warning signs that there could be issues are on the stems.  The stems in some fields are heavily colonized with a mix of disease pathogens that cause Anthracnose, Cercospora, and pod and stem blight (Figure 1).  The bottom line is that all of these diseases can be better managed with higher levels of resistance but ultimately during 2018 – we had a perfect storm, lower levels of resistance combined with h
