production by 2018, reducing imports and increasing income. However, to date, rice yields have remained at 2.2–2.5 tonnes per hectare, well short of calculated potentials. Ragasa and Chapoto
studied ten major rice-producing areas of Ghana, comparing the effects of irrigation, fertilizer use, and a host of additional factors. Of these, the use of irrigation was far more
effective than any other intervention. Lowland areas without irrigation could see improved yields with the use of fertilizer, certified seeds, and so on, but the increase did not match what
irrigation alone could achieve. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Access Nature and 54 other Nature
