Investigation of Soybean Seed Treatment and Inoculant in Southeastern SD, 2018
Soybean seed treatment products are widely utilized by many farmers in southeastern South Dakota and the surrounding area. These products often consist of an insecticide/fungicide combination, and/or inoculant that is mixed and placed on the seed as a pre-treatment before the grower plants the crop.
Instinct HL and Nitrogen Management Effect on Winter Wheat Yield
Nitrogen (N) additives to control N losses through volatilization, denitrification, and leaching are widely used in the Midwest. Slowing the conversion of nitrogen fertilizers to nitrate may lessen leaching and denitrification losses if precipitation or soil becomes saturated.
Winter Survival and Spring Stand Counts in Winter Wheat
Every winter, growers are curious if their wheat field will survive the winter. Not enough snow cover during the coldest days, spring flooding, and ice injury are the main reasons for plants to die. The only way to get a true assessment of winter survival is to scout the field in the spring.
Plant Growth Regulator Reduces Height, Lodging in Oats
With the goal of reducing lodging in oats, SDSU Extension and a research team initiated a multi-location trial in 2018 growing season to study the effects of plant growth regulator (PGR) on oat performance.
Effects of Snow on Wheat
Even though snow that comes with the onset of cool temperatures can be a nuisance for our daily activities, it can benefit a winter wheat crop a great deal.
Sunflower Hybrid Variety Trial Results
In 2024, sunflower trials were planted at two locations in South Dakota.
Soybean Variety Trial Results
Conventional soybean and soybean variety testing results for different locations across South Dakota.
Corn Hybrid Trial Results
In 2024, corn hybrid, conventional corn hybrid and corn silage trials were conducted at different locations throughout South Dakota.
Application of Nitrogen Fertilizer in Soybeans
SDSU Extension conducted a study during the 2016 growing season at five Eastern South Dakota sites to evaluate the effects of added N fertilizer (as urea) on soybean yields.
Using Plant Growth Regulator in Oats Grown for Grain
With growers’ interest emerging, SDSU Extension and research faculty teamed up and initiated a study in 2016 in Northeast SD to evaluate the effects of plant growth regulator. The study was conducted at the SDSU Northeast Research Farm (NERF) near South Shore, SD.
