b'SOYBEANSO NOTES FOR ALL SOYBEAN TABLESI Maturity Notes:1 Soybean varieties have been organized into 4 maturity zones - very early, early, mid and long season areas. L 2 Maturity grouping is a ranking of maturity provided by seed suppliers. Rankings are assigned to assist growers in selecting varieties suited fortheir area.S 3 Relative days to maturity is the number of days from seeding to plant maturity (95% of the pods on plant are mature with seeds rattling in thepods when plant is shaken). Expressed as + or - days from the check. Caution needed when using only one year data to evaluate maturity and yield. Using multiple years will provide a better indication on how a variety will mature with different growing seasons. Actual days to maturity E for the check is found in the grey characteristics check box at the bottom of the table.E General Notes:1 Roundup Ready and Conventional soybean varieties are evaluated separately, meaning direct comparison of varieties between different tablesD is not possible. All trials are solid seeded at 210,000 seeds/acre.2 Hilum colour can range from Yellow (Y), Imperfect Yellow (IY), Grey (G), Brown (BR), Buff (BF), Tan(TN), Clear (CL), Imperfect Black (IB) or Black(BL) and is solely a marketing issue. The hilum is the point on the soybean seed where it attaches to the pod.3 Iron Deficiency Chlorosis (IDC) rating scores 1=green leaves, 2=yellowish leaves, 3=green veins with yellow leaves, 4=brown dead tissueC between green veins, 5=severe chlorosis and a stunted growing point. Ratings were taken from a site prone to iron chlorosis over the last 3 years. IDC tolerant varieties are varieties with lower IDC Scores and perform better on soils prone to iron deficiency.R 4 Iron Deficiency Chlorosis (IDC) grouping is used because varieties will have different visual rating scores from year to year. Numerical ratingswhich are close but are in different groupings will show similar symptoms. Both numerical ratings and groupings should be considered togeth-O er when judging IDC. Tolerant=leaves stayed green, Semi Tolerant=leaves turn yellow then turn green, Susceptible= leaves went chlorotic and had dead patches on their leaves and were often stunted.PS MANITOBA SOYBEAN MATURITY MAPThe Soybean Maturity Map outlines the longest maturity suggested for each production area but earlier varieties can also perform well.
