The South Dakota Corn Performance Test is conducted each year to supply impartial information concerning hybrids and open-pollinated varieties to farmers, hybrid seed-corn dealers and producers, and others interested in corn. The plots for this test are located in nine districts of eastern South Dakota. There were 456 entries comprising 156 different hybrids and open-pollinated varieties in 1944. Two to five adapted open-pollinated varieties were planted in each plot as check varieties. Data are presented on yield, moisture percentage of the grain at harvest, and stand. It should be emphasized that there are many hybrids which have performed well in South Dakota and that the top hybrid in any district for any one year is not necessarily the best one. Statistical measures are included to be used in judging the advantage or disadvantage of purchasing a given hybrid. Long-time averages are the best indication of the performance of a hybrid and as these tests continue to be conducted their results will become more valuable. Used with discretion, these data will provide readers with valuable information on the production, sale, and purchase of hybrid corn.
