Many times the questions has been asked – What kind and quality of seeds are South Dakota farmers planting? In an effort to at least partially answer the questions, a drill box survey was conducted in the early spring of 1964. The survey was a combined effort of individuals from the Seed Certification Service of the South Dakota Crop Improvement Association, State Department of Agriculture, Cooperative Extension Service, and Agronomy Department of S.
