2 Abnormally hot and dry conditions reduced yields and uniformity at some locations. Because of these conditions, the results of the nonirrigated tests at Keiser, the Starks Farm, and the early MGIV test at Rohwer are not reported.

-- Strains were tested under irrigated conditions at Keiser and Rohwer only.

// Maturity group 7 soybeans were tested at Stuttgart, Rohwer, and Starks Farm only.
