Figure 4:
Soybean yield increase in weeded plots in 2003 and 2004

Figure 4. Iowa 3006 had less than a 10 percent yield loss due to weeds in both 2003 and 2004. Needless to say, we now grow Iowa 3006 on most of our production acreage. Simple, on-farm variety trials are a good long-term investment, but bear in mind that results may vary on different soils or under different weather conditions. (GH=Great Harvest)
