ABSTRACT: It is presumed that remarkable increases in cotton productivity in India have come about through bacillus thuringiensis cotton and that this approach therefore must be replicated in other crops. This article explores the myth of rising yields of genetically modified crops and points out that genetic engineering has been at best neutral with respect to yield and in many cotton growing countries the average cotton yields have stagnated since the adoption of Bt cotton.
