Purpose -The purpose of this paper is to provide an overview of the current state of knowledge on the economic performance of genetically modified (GM) cotton worldwide based on a wide range of data and source from available literature, and second to assess yield gain and economic performance. Design/methodology/approach -A systematic review was captured to provide the evidence of potential benefits of GM cotton. A country-specific analysis was conducted in order to compare economic indicators and employed meta-analysis to find out the significance of the different of GM cotton over its counterpart.Findings -This paper depicts positive impact of commercialized GM cotton in terms of net revenue, and the benefits, especially in terms of increased yields, are greatest for the mostly farmers in developing countries who have benefitted from the spill over of technology targeted at farmers in industrialized countries.Research limitations/implications -Due to the variability of the data which came from different methodologies, it is difficult to determine the differences of the performances each individual study.Practical implications -This, it is believed that results from this study can be useful for operations of all sizes as the authors think about what needs to be focussed on for long-term producers survival. Originality/value -The paper clearly indicates that China is the highest cotton yield of GM cotton, the lowest cost of GM seed and the lowest cost of chemical spray compare to any other countries. Therefore, this is the fact that the adoption of GM cotton has been widely spread among the farmers across the regions in China. Keywords Agriculture, Benefits, Effects, Cotton growers Paper type General review IntroductionThe benefits of genetically modified (GM) cotton continue to be disputed, despite rapid and widespread adoption since their commercial introduction in the USA in 1995 and first planted in 1996 ( James, 2009). Since its 1996 debut on US cotton farms, according to James (2012) biotech cotton reached 24.3 million hectares in 2012 down from the 24.7 million hectares grown in 2011. With lower global price ...

Multiyear (2010 – 2014) Assessment of Bollgard II® Efficacy in Commercial Small Scale Farmer Fields in Burkina Faso

“…These results were also reported for China (with 67% reduction) for Australia (with 64% reduction) (Witjaksono et al, 2014). Because the Bt genes don't control the sucking pests (aphids, white flies, jassides, and bugs), it was recommended in Burkina Faso to spray two times at 86 and 100 days after cotton emergence.…”

“…On average in China, the yield increase due to Bttoxins effectiveness ranged from 31 to 63% (Witjaksono et al, 2014). In the US the yield increase over the past ten years was approximately 33% (Witjaksono et al, 2014). In terms of income, Sankula et al (2005) reported the net benefit of US$74.29/ha for conventional cotton and US$128.85/ha for Btone.…”

Uncovering the Drivers and Regional Variability of Cotton Yield in China

“…The total power of agricultural machinery indicates the level of mechanization in cotton production. The utilization of genetically modified Bt cotton enhances yield; considerable evidence suggests that Bt cotton has brought economic benefits to farmers in numerous countries [30]. Starting from the successful development of domestically produced anti-insect cotton (GK) in China in 1994, which effectively eradicates cotton bollworms, the commercial cultivation of insect-resistant cotton was approved by the Ministry of Agriculture in 1997.…”
