Genetically modified (GM) crops have been and continue to be a subject of controversy despite their rapid adoption by farmers where approved. For the last two decades, an important matter of debate has been their impact on pesticide use, particularly for herbicide-tolerant (HT) crops. Some claim...

Concern about declining growth in crop yields has renewed debates about the ability of biotechnology to promote food security. While numerous experimental and farm-level studies have found that adoption of genetically engineered crops has been associated with yield gains, aggregate and...

Russian crop production reflects a significant rise in the cultivation of corn and soybeans. One of the highest growth rates, along with a significant share in the national output, can be found in the Central Black Soil Region (CBSR). The rapid expansion of corn and soybeans acreage raises a...

We use a large, rich dataset compiled from results of university extension trials to estimate the contribution of genetic modification (GM) to changes in corn yield in the United States from1997 to 2009. Through repeated experimental trials, we obtain consistent estimates of the effect of these...
