Gene crops ‘do not yield more’

GENETICALLY modified crops do not necessarily produce better yields, acccording to research by the US Department of Agriculture (USDA).

The study analysed commercial crop results for 1997 and 1998 in regions where traditional and GM varieties of cotton, maize and soya were being grown.

The study did not find yields improved, while pesticide use was virtually unchanged.

Bill McBride, an economist with the USDA, said it would not be possible to make any predictions about yields before planting on the basis of the research.

The research is reported in New Scientist magazine.
