Research Focus

The focus of this project is to provide recommendations for soybeans planted later in the season.


  • Develop double crop soybean recommendations following winter malting barley including Rhizobia inoculant, fungicide + insecticide seed treatment, foliar fungicide at R3, foliar insecticide eat R3, and foliar insecticide at R5.
  • Evaluate the effect of winter malting barley biomass and residual nitrogen on double crop soybean stand and yield.
  • Generate Extension programming and materials to transfer knowledge to farmers and other stakeholders.
  • Identify early-maturing winter-hardy barley with high malting quality to further expand double crop soybean opportunities.


  1. Plot maps were created and the study was planted after winter malting barley harvest in Wooster and South Charleston, Ohio.
  2. Initial stand counts were conducted approximately three weeks after planting. R3 and R5 treatments (foliar fungicide and foliar insecticide combinations) were applied. Disease was rated 2 and 4 weeks after the R3 foliar fungicide application. Leaf area affected by insect defoliation was measured at R5 and insects were collected via sweepnet.
  3. Final stand counts were conducted. Just prior to harvest, 10 plants per plot were collected to assess pod feeding. The trials were harvested.


At project completion, double crop soybean recommendations will be generated for both traditional and non-traditional double crop production areas of Ohio. These results will not only be important for soybeans following winter malting barley, but also in years when wheat is harvested early or harvested at a higher moisture content.
