Colombian GM maize boosts production
Genetically modified maize farmers in Colombia have seen almost 23% higher yields than farmers using conventional lines, researchers claim. A team from two universities based in Bogota carried out a study among 20 farms in one of the regions to have been approved for GM maize planting, Agro-Bio Colombia reports. The higher yield resulted in a doubling of profits, it adds. The team further found that the net environmental impact from employing GM lines was lower than that for conventional. They considered the use of herbicides and insecticides in the analysis. No insecticides had been applied on the GM maize lines. The study was carried out in the first half of 2009, and all results have been published in the journal, Land BioScience. Colombia has granted eight “semi-commercial” approvals for GM maize crops ( Agrow No, 597, p 21).
