- Observation The 200 genotypes varied widely in grain and fodder yield.
- Intervention effect Grain yield response to RP and SSP ranged from 1 to 160%.
- Intervention effect Phosphorus application significantly increased grain and fodder yields at both locations.
- Intervention effect Phosphorus application significantly increased shoot-to-root ratio.
- Intervention effect Phosphorus application reduced AMF infection by at least 50%.
- Observation Genotype differences were significant for some paired means but inconsistent across parameters and locations.
- Observation Cowpea genotypes differed in AMF colonization.
- Observation Cowpea genotypes differed in shoot growth relative to root development.
- Observation Cowpea genotypes differed in relative phosphorus use efficiency.
