The comeback of perennial grains in Malawi

In Malawi, the rise of pigeonpea and cassava production has created conflicts. Farmers in Malawi cut pigeonpea and sorghum to extend production for more than one growing season. They also grow cassava, a perennial food crop that has a proven track record of abating hunger. Rogé et al. show that research is needed to evaluate trade-offs of ratooned systems, to further develop markets for smallholder farmers, and to breed ratoon crops with yield stability and resistance to diseases and pests.
