For 14 consecutive years, DOANE Marketing Research, Inc. has conducted a U.S. Farm Corn Seed Study. This annual syndicated study tracks corn growers specific hybrids planted, purpose for planting, source of purchase, prices paid per unit and kernels per acre planted. For the last five years, clients who subscribe to the study have been interested in viewing the percent total acres planted with conventional (non-GMO) seed vs. GMO seeds. The graphic below shows the relationship of acres planted over the past five years.

Although the first GMOs were planted in 1996, the graphic illustrates the rapid increase in GMO plantings in 1998 through 1999. For years 2000 and 2001, GMO seed planting settled into the 30 to 32 percent of all acres range.

Another area of interest is the price paid per unit (80,000-kernel bag of seed) relationship between the two seed types during the time of rapid GMO seed adoption by U.S. corn growers. In the following graphic, the net price paid for conventional seed by years 1997 to 2001 are plotted next to the prices paid for GMO seed. The single largest difference by year was $20.50/unit in 1998 - the single most rapid GMO adoption year.

For the years 1999 through 2001, the net unit price difference between the two seed types ranges from $17.25/unit to $18.97/unit.
