Genetically Engineered (GE) Soya Yields Less

Publication - 26 January, 2010
Monsanto's genetically engineered (GE) "Round-up Ready" soya yields 5 to 10 percent less than natural varieties, costing farmers billions of dollars every year.

Executive summary: Studies demonstrate that Monsanto’s ‘Roundup Ready’ (glyphosate-tolerant) soya has a 5-10 percent lower harvest compared to modern conventional soya lines. These lower-yielding genetically engineered (GE) soya varieties cost farmers billions of dollars every year. Evidence of lower yields, called ‘yield drag’, is an example of the unpredictability and unintended consequences of GE. Yield drag losses were and remain avoidable through the use of modern conventional varieties.
