corn hybirds, corn variety trials, corn performance tests
Each year several hundred different corn hybrids are offered for sale to South Dakota farmers. It is a real problem for the purchaser to know which hybrid corn to buy because the various hybrids sold differ in yielding ability, maturity, lodging resistance and other agronomic characteristics. Therefore, the Agronomy department of the South Dakota Agricultural Experiment Station conducts yield trials each year on commercial hybrids and open-pollinated varieties in order to provide impartial, comparable performance records. Entries in each test are those hybrids which, according to surveys, are being sold to the greatest extent to farmers in that area of the state represented by the test. The information presented should be of value to both the purchaser and the producer of hybrid seed
