Genetically-Manipulated Crops Prove to Have Reduced Yields According to Independent Research

For years, biotechnology companies and government beaurocrats have been telling farmers and others that genetically-manipulated crops can increase crop yields. Independent research now shows that not only is this not true, but crop yields from many genetically-manipulated crops is worse than that of normal crops.

Not surprisingly a number of US agronomists are quietly advising farmers that if they are considering changing from traditional varieties for economic reasons they need to approach the question of the performance of transgenic varieties with great care.

This loss of yield with GM crops needs to be seen in the context of the increased costs that the technology imposes. For example, with Roundup Ready soya farmers have to pay the extra "technology charge" to use the GM crop in the first place and on top of this, as Charles Benbrook has pointed out, farmers are finding they need to apply 2-3 applications (not just one as Monsanto advertises) of Roundup - expensive! Benbrook says 2 or 3 other herbicides may also need to be applied. All of whichmakes "for the most expensive soybean seed-plus-weed management system in modern history" [Synthesis/Regeneration 19, Spring 1999 p. 15].
