Research demonstrated that the raised-bed and furrow-system approach works with rice and provides many advantages to farmers. Toxicity of arsenic to rice that had caused crop yield to decline was substantially reversed by using a raised-bed and furrow-system of production. This represents a new way of growing rice that can also be extended to other crops. Several agencies are interested in disseminating the technology in Bangladesh.
impact statement issue
Farmers were observing progressively reduced yields of rice in arsenic-affected areas, threatening food security and causing them to shift to less desirable crops.
impact statement response
Appropriate technology that we were working with elsewhere was applied to the arsenic problem in on-farm research. The impact was favorable and the technology is ready for widespread adoption.
impact statement summary
Toxicity of arsenic to rice that caused yield to decline from seven-to-two tons-per-hectare was substantially reversed by using a raised bed and furrow system of production that provided a more oxygenated environment. Arsenic content of rice grain and straw were reduced up to two-fold and six-fold, respectively.
