Ebelhar et al., 2005
OBJECTIVESDetermine the effects of potassium, chloride, boron and manganese nutrition on the response of soybeans to diseases (possibly including Asian soybean rust)
Evaluate the nutrient interaction effects with and without the application of fungicides
Compare these effects across Roundup Ready and conventional herbicide programs.

SUMMARYFoliar application of B and Mn increased the leaf composition of B and Mn, respectively, and caused some injury to the soybean plants but had no effect on yield.Disease pressure was low, but was affected by variety choice and by fungicide treatment, but not fertilizer treatment at Dixon Springs.Fungicide application at Brownstown caused some leaf injury and slightly reduced yields.
