Research Update

Submitted by Mark Stadtlander

The 2020 Kansas Summer Annual Forage Hay and Silage Variety Trial research report is now available online. In 2020, summer annual forage variety trials were conducted across Kansas near Garden City, Hays, and Scandia. All sites evaluated hay and silage entries. Companies were able to enter varieties into any possible combinations of research sites, so not all sites had all varieties. Across the sites, a total of 98 hay varieties, 78 sorghum silage varieties, and 11 dual-purpose sorghum silage varieties were evaluated.

The 2021 Field Research Report is now available online. This year's report includes topics of corn nitrogen, tillering, and yield responses; cropping and tillage systems in soybeans; history of sorghum grain filling; management practices of forage hay and silage, macronutrient and irrigation practices, and technology sensors; sulfur fertilization in soybeans; weed science management in brome hay, green foxtail control, kochia control, grass weeds in Enlist E3 soybeans, and tank mixing; wheat production responses to fungicide types and application methods, seeding rates, and plant growth regulators.
