Performance of green manure legumes on exhausted soils in Northern Zimbabwe: A soil fertility network trial - Harare (Zimbabwe) Soil Fert Net|CIMMYT : 1998 - Printed
We ran a simple trial with farmers in northern Zimbabwe during 1996/97 to test three green manures for biomass production on fields that farmers reported to be too exhausted to grow maize. Sunnhemp and fish bean were inconsistent in plant establishment, growth and biomass production. Velvet bean produced more than 4 t/ha of above-ground biomass dry weight at eight out of 12 sites, most of which were moderately acidic. At only two sites were the biomass yields below 1 t/ha. These results provide further evidence for the promising performance of velvet bean on poor granitic sand soils in the wetter zones of northern Zimbabwe. Wider assessments with more farmers are needed.
