6. the amount of a crop that a farmer can harvest per acre is referred to as crop yield. farmers have been able to increase their crop yield by adopting the use of genetically modified (gm) crops.
what’s the general trend shown

The general trend shown is that the amount of crop that a farmer can harvest per year keeps increasing by adopting the genetically modified crops in the U.S. and it keeps growing steadily. If it keeps up the future of GM crops use will depend on the ability of the farmers to adopt best management practices and the acceptance of the consumer for products from GM sources.
