Soybeans require 105–125 frost-free days from planting to maturity. Select varieties based on regional growing season length.
Varieties are either glyphosate tolerant (Roundup Ready), glyphosate + dicamba tolerant (Xtend), glyphosate + 2,4-D tolerant (Enlist) or non-GM (conventional). See the MPSG Soybean Variety Evaluation Guide below or Seed Manitoba for days to maturity, yields, IDC ratings, Phytophthora root rot (PRR) resistance and soybean cyst nematode (SCN) resistance.
Variety protein values are available at seedmb.ca. Genetics, environment and management can influence soybean protein concentration and research is needed to understand soybean protein in Manitoba.
Variety performance of soybeans are tested at multiple locations throughout Manitoba every year. The purpose of variety performance testing is to provide Manitoba farmers and agronomists with independent information on yield and agronomic characteristics. The information is summarized in the guides below and designed to help select the best varieties suited to each farm and growing region in Manitoba. Information is available on yield, maturity and other important agronomic and quality traits.
