Insect pests are a major constraint to cowpea production in northern Ghana where it is widely cultivated. Field experiments were conducted to evaluate the effects of planting date, cultivar and insecticide applications for the management of major insect pests attacking cowpea. There were 4 planti...

The parasitic weeds Striga gesnerioides (Willd.) Vatke and Alectra vogelli (Benth.) cause considerable demage to cowpea [ Vigna unguiculata (L.) Walp] in the semiarid regions of Africa. Systematic screening has revealed few cowpea varieties to be resistant. Of these, B 301 is resistant to both st...

Cowpea flower bud thrips causes about 80% yield losses in cowpea. Host plant resistance is the most easy and durable solution to the damaging effects caused by this insect. However, resistance to thrips is quantitatively inherited, thus less amenable through conventional breeding. The objective o...

Plants damaged by herbivores are known to release odors attracting parasitoids. However, there is currently no information how leguminous plants damaged by the pod borer Maruca vitrata attract the exotic larval parasitoid Therophilus javanus, which was imported into Benin from the putative area o...

A preliminary trial was conducted to determine if there were variabilities in seedling morphology of selected cowpea varieties and determine their heritability with aim that this could be used in future cowpea breeding for selection at seedling stage. The characters studied include hypocotyl, epi...

Impact studies assuming exogenous technology adoption are bound to overstate or understate the true impact of improved agricultural technologies, especially in situations where agricultural technologies are targeted to, or adopted by, a certain group of farmers. This paper examined the impact of ...

Autor: Craufurd, Peter Q. Wheeler, T.R.

The effects of drought and plant density on fractional interception (f), radiation-use efficiency (RUE) and dry matter accumulation and partitioning to seeds in cowpea (Vigna unguiculata) need to be quantified in order to calibrate cowpea simulation models for West Africa. Accordingly, a short du...

Forty eight accessions of cultivated cowpea were assessed using 12 simple sequence repeat (SSR) markers. The unweighted pair group method with arithmetic mean (UPGMA) dendrogram constructed revealed three main clusters when truncated at 65% similarity coefficient. All accessions showed high genet...
