How to Select Varieties

Problem or Difficult Fields...

1)   Identify fields that have had problems in the past.  Problems to consider 
     may include diseases, nematodes, or fields that make planting or harvest 
     difficult because of extremely dry or wet conditions.  The Mississippi 
     Cooperative Extension Service offers a disease diagnostic service and 
     nematode analysis free of charge.

2)   Use Tables 9A-9E to select varieties for the fields that need nematode or 
     other pest resistance.

3)   Select varieties from the multiyear-average column at each location.  
     Identify those varieties that have the desired pest resistance along with 
     high yield potential.  Use the data from a test site or sites with a soil 
     type similar to that where the soybeans will be grown.  Consider planting 
     dates and maturity dates that may allow you to avoid historical field 
     problems.

Non problem Fields...

1)   Identify the farm's highest yielding fields that have no specific disease 
     problems.

2)   Select varieties with the best yield potential from the multiyear-average 
     column at each location.  Use the data from a test site or sites with a 
     soil type similar to that where the soybeans will be grown.

3)   Try new varieties on a limited number of acres if the yields are good at 
     several locations.  Don't abandon older varieties that are yielding well 
     unless research and experience show an advantage for newer varieties.
