Cotton farming has been a significant contributor to Kenya’s economy for many years. However, the sector has been facing numerous challenges, including pests and low-quality seeds, leading to low yields and reduced incomes for farmers. The Kenyan government is looking to revive the ailing sub-sector through the use of genetically modified (GM) pest-resistant Bt cotton seeds.
Bt cotton is a genetically modified variety that has been engineered to resist infestation by the African Bollworm, the single most destructive cotton pest in Kenya. The use of Bt cotton seeds has been shown to increase yields four-fold over conventional varieties, leading to higher incomes for farmers. Additionally, the Kenyan government is distributing free Bt cotton seeds to farmers in Nyanza and Western regions to boost production and create more jobs.
With a kilogram of cotton going for ksh50, a Bt cotton farmer can earn ksh75,000 (US$656) — triple the amount earned by his conventional counterpart. The potential for increased income and job creation through the use of Bt cotton seeds makes it a promising solution for the future of cotton farming in Kenya. This article will explore the benefits and challenges of using Bt cotton seeds and its potential impact on the Kenyan economy.

Benefits of BT Cotton Seed
BT cotton seed is a genetically modified variety of cotton that has been engineered to produce a toxin that is deadly to certain pests, especially the cotton bollworm. This toxin is derived from the bacterium Bacillus thuringiensis, hence the name BT cotton. Here are some of the benefits of planting BT cotton seed:
- Reduced pesticide use: Since BT cotton is resistant to cotton bollworm, farmers who plant it can reduce the amount of pesticides they use to control pests. This not only saves farmers money, but also reduces the environmental impact of cotton farming by reducing the amount of chemicals released into the environment.
- Increased yields: Studies have shown that BT cotton can increase cotton yields by up to 24% compared to non-BT cotton. This is because the plants are protected from pests that can damage the cotton bolls, leading to higher quality and quantity of cotton.
- Higher profits: Farmers who plant BT cotton can earn higher profits due to the increased yields and reduced pesticide use. In fact, studies have shown that BT adoption had increased cotton yields by 24%, farmers’ profits by 50% and farm household living standards by 18%.
- Durable resistance: BT cotton has been shown to provide durable resistance to the key Lepidopteran pest American bollworm, reducing the need for chemical applications and thus reducing worker and environmental exposure to chemical insecticides.
Overall, BT cotton seed has the potential to revolutionize cotton farming in Kenya and other countries by reducing the use of pesticides, increasing yields, and improving the livelihoods of farmers. However, it is important to note that the long-term effects of genetically modified crops on the environment and human health are still being studied, and caution should be taken when introducing new technologies into agriculture.
Challenges and Risks
While Bt cotton has shown promise in increasing yields and reducing the use of pesticides in other countries, there are still several challenges and risks that need to be addressed in Kenya.
One major challenge is the lack of access to quality seeds. African cotton farmers often struggle to find affordable, high-quality seeds that can increase yields and profits. This can lead to lower yields, lower incomes, and difficulty recouping investments.
Another risk is the potential for pests to develop resistance to the Bt toxin. In India, for example, Bt cotton has been successful in controlling one major pest, but resistance has developed in another pest, and non-target pests have surged in population, leading to increased pesticide use and decreased yields.
Additionally, there may be unintended consequences of widespread adoption of Bt cotton. For example, some farmers may decide to use more fertilizer because of the increased yields from Bt cotton, which can lead to environmental damage and increased costs for the farmer.
Finally, there is a risk that Bt cotton may not be profitable for all farmers. While some farmers may see increased yields and profits, others may not see the same benefits due to differences in soil, climate, and other factors. It is important to carefully evaluate the potential benefits and risks of Bt cotton before widespread adoption.
Impact on Kenyan Cotton Industry
The introduction of Bt cotton in Kenya has had a significant impact on the country’s cotton industry. The genetically modified seed has been shown to be more resistant to pests and diseases, leading to higher yields and better quality cotton. This has resulted in increased profitability for farmers and a boost to the textile and apparel industry.
According to the Kenyan government’s Big Four Action Plan, Bt cotton is expected to create 50,000 jobs and generate Sh20 billion in apparel export earnings per year. This is a significant increase from the current state of the industry, which has struggled due to low quality seed and pest infestations.
One of the key benefits of Bt cotton is its ability to resist the African bollworm, a common pest that has plagued cotton farmers in Kenya for years. This has led to a reduction in the use of harmful pesticides, which can be costly and have negative environmental impacts. Additionally, Bt cotton has been shown to have a higher germination rate and earlier maturity than conventional cotton, leading to a more efficient and productive farming process.
Since the commercialization of Bt cotton in Kenya, farmers have reported significant increases in yield. While conventional cotton farmers yield between 500 to 700kg per acre, those growing Bt cotton have reported harvests of 1,500 to 2,000kgs from the same acre. This has led to increased profitability for farmers and a boost to the industry as a whole.
Overall, the introduction of Bt cotton in Kenya has had a positive impact on the country’s cotton industry. With higher yields, increased profitability, and a reduction in harmful pesticides, Bt cotton has the potential to transform the industry and make Kenya a regional leader in textile and apparel production.
Conclusion
With the introduction of Bt cotton in Kenya, the future of cotton farming in the country seems promising. The seed, which is genetically modified to resist the African Bollworm, has been shown to boost yields four-fold compared to conventional cotton.
Moreover, the Kenyan government’s Big Four Action Plan is banking on Bt cotton to create 50,000 jobs and generate Sh20 billion in apparel export earnings per year. This is a significant boost to the country’s economy, especially considering that Kenya is the top apparel exporter in sub-Saharan Africa.
Kenyan farmers who have already started cultivating Bt cotton have reported earning triple the amount earned by their conventional cotton counterparts. This is a clear indication that the seed has the potential to revolutionize cotton farming in the country.
It is worth noting that Bt cotton is currently planted in 15 countries globally covering an area of 24 million hectares. This means that Kenya is not alone in adopting the seed as a solution to the challenges facing cotton farming.
Overall, the introduction of Bt cotton in Kenya is a step in the right direction towards achieving food security, job creation, and economic growth. With the right policies and support from the government, the seed has the potential to transform the cotton industry in the country and benefit both farmers and the economy as a whole.
