U. of Nebraska study reveals yield problems with GM soybeans

(May 29, 2001 –Cropchoice news) – University of Nebraska researchers produced a peer-reviewed study showing suppressed yields in transgenic soybean plants. They found that the transgene or the process of inserting it into the plant, combined with the genetic differences between the genetically modified and conventional varieties, reduced yields in the former by 5 to 10 percent. The study found no evidence that spraying glyphosate (Roundup) reduced yields.

According to the conclusion to the study: "…Producers should consider the potential for 5-10% yield differentials between GR and non-GR cultivars as they evaluate the overall profitability of producing soybean. Cultivar choices are best based on i) previous weed pressure and success of control measures in specific fields, ii) the availability and cost of herbicides, iii) availability and cost of herbicide-resistant cultivars, and iv) yield, and not solely on whether cultivars are herbicide resistant. Based on our results from this study and those of Elmore et al., 2001, the yield suppression appears associated with the GR gene or its insertion process rather than glyphosate itself."
