Stability of Sources of Resistance to Cowpea Aphid (Aphis craccivoraKoch, Hemiptera: Aphididae) across Major Cowpea Production Zones in Ghana

Francis Kusi; Jerry A. Nboyine; Patrick Attamah; et al. International Journal of Agronomy 2020. doi:10.1155/2020/8869334

Other claims from this paper (7)

Observation Cowpea genotype SARC1-57-2 was stable in resistance to aphids across all ecologies tested in Ghana.
Observation SARC1-57-2 had a high vigour score of 3.8 ± 0.03 compared with susceptible genotypes.
Observation SARC1-57-2 had low plant mortality of 3.7 ± 0.22% compared with susceptible genotypes.
Intervention effect Aphid infestation significantly delayed flowering and maturity of cowpea.
Intervention effect Aphid attack caused grain yield loss estimated at 3.8 to 32.8%.
Recommendation The resistant genotype can be incorporated into cowpea breeding programmes to breed aphid-resistant cultivars.
Recommendation Cultivating improved aphid-resistant cultivars is expected to reduce pesticide usage in cowpea production.

Intervention effect In maize cowpea intercrops, cowpea grain yield of the upright varieties was 2.5-4 times higher than that of the climbing varieties.
Intervention effect Climbing cowpea varieties had 1.46-1.62 times more vegetative biomass at the end of the season than the upright varieties (significant, P<0.01).
Intervention effect Leaf-stripping and detasselling of maize significantly increased cowpea grain yield by 5.46%.
Intervention effect Leaf-stripping and detasselling of maize significantly increased cowpea 1000 grain weight by 11.7%.
Intervention effect Leaf-stripping and detasselling of maize significantly increased the number of cowpea grains per pod by 11%.
Intervention effect Leaf-stripping and detasselling of maize significantly increased the number of cowpea pods per plant by 17%.
Intervention effect The climbing cowpea variety R ex-Mbare suffered a 68.5% yield reduction when intercropped with maize.
Intervention effect Leaf stripping and detasselling in the maize bean intercrops increased maize grain yield by 12% compared to intact maize.
Intervention effect Intercropping with climbing cowpea varieties caused a greater maize grain yield reduction (66%-67.7%) than with upright cowpea varieties.
Intervention effect Intercropping with upright cowpea varieties caused a maize grain yield reduction of 29%-43%.
Intervention effect Weed biomass was reduced by 46% in the intercropped treatments compared with the cowpea monocrop treatments.
Recommendation The authors conclude that new upright cowpea varieties are better adapted for intercropping with maize than traditional trailing and climbing varieties.
