Adoption of genetically modified crops in the United States

Adoption of genetically modified crops in the U.S. from 1996 to 2022.

Usage

data("usda.gmoadoption")

Format

A data frame with 145 observations on the following 3 variables.

year: Year of crop
crop: Crop type
percent: Percent of planted acres

Details

HT indicates herbicide-tolerant crops. Bt indicates insect-resistant (Bacillus thuringiensis) crops. The "percent" column is the percentage of planted acres for each crop that were genetically modified. HT/Bt for corn and cotton are not mutually exclusive categories. For example, as time progressed corn hybrids tended to be both HT and Bt.
