Boosting land productivity using ‘doubled-up’ legume intercropping in Malawi

This evidence brief explains how Africa RISING is using an intercropping system known as ‘doubled-up’ legume technology using two complimentary grain legumes. Groundnut–pigeon pea intercropping is the most successful doubled-up system thanks to the two crops’ contrasting structures and maturity dates. Continue reading

Doubled-up legume technologies in conservation agriculture show potential for scale up in Zambia

The doubled-up legume system in conservation agriculture is premised on the belief that while farmers will be in a position to get the usual benefits of the doubled-up legumes (‘double’ the grain output per farm, hence more food and also ‘double’ soil fertility through the leafy biomass components of groundnuts and pigeonpea); they will also potentially benefit more from increased moisture retention towards the end of the season as well as reduced labor in land preparation, if the backbreaking conventional tillage practice of ridging can be avoided.

Increasing pigeonpea productivity in a novel doubled-up legume cropping system in Malawi

At this week’s international conference on Integrated Systems Research for Sustainable Intensification in Smallholder Agriculture, Chiwimbo Gwenambira (Michigan State University) presented a poster explaining a a novel doubled-up legume cropping system in Malawi. Continue reading
