Scientists find GM soya produces less than conventional equivalent

Genetic modification actually cuts the productivity of crops, the Independent on Sunday reported a new study as finding, undermining claims that the controversial technology increases yields and is needed to solve the growing world food crisis.

The study, which carried out over the past three years at the University of Kansas, found that GM soya produces about 10% less food

than its conventional equivalent. The report quoted professor Barney Gordon as saying many farmers who had changed over to the GM crop had "noticed that yields are not as high as expected even under optimal conditions".

Gordon grew a Monsanto GM soybean and an almost identical conventional variety in the same field, the report said. The modified crop produced only 70 bushels of grain per acre, compared with 77 bushels from the non-GM one.
