Other claims from this paper (8)
- Intervention effect In Mozambique, inoculation with one of the Brazilian rhizobium strains more than doubled cowpea grain yield, which reached 1.4 Mg/ha despite witchweed damage.
- Intervention effect In northern Ghana, rhizobium strain BR 3299 tripled cowpea nodule weight at 35 days after planting in August (530 mg per plant).
- Intervention effect The other inoculants, including BR 3267 and a mixture of BR 3267 and BR 3299, increased cowpea nodule weight to over 300 mg per plant.
- Intervention effect In the second experiment, inoculation increased cowpea grain yield significantly by 39% to 57%, reaching over 2.0 Mg/ha.
- Intervention effect Inoculation of cowpea gave similar increases in nodulation and grain yield in 22 on-farm trials.
- Intervention effect Nitrogen fertilizer application promoted cowpea vegetative growth.
- Intervention effect Nitrogen fertilizer application did not increase cowpea grain yield or nodulation.
- Recommendation The authors conclude that inoculating cowpea with highly effective rhizobium strains can enhance grain yield of smallholder farmers in Africa.
