Highly specific seed market classes for cowpea and other grain legumes exist because grain is most commonly cooked and consumed whole. Size, shape, color, and texture are critical features of these market classes and breeders target development of cultivars for market acceptance. Resistance to biotic and abiotic stresses that are absent from elite breeding material are often introgressed throug...

Cowpea [Vigna unguiculata (L.) Walp.] is an important warm-season legume grown primarily in the semi-arid tropics. The majority of cowpea is grown by subsistence farmers in west and central sub-Saharan Africa, where its grain and stover are highly valued for food and forage. Despite its economic and social importance in developing parts of the world, cowpea has received relatively little attent...

to study the effect of strip intercropping pattern with cowpea and soybean on sorghum fodder yield an experiment was conducted at research farm of university of tehran (karaj) during 2005. the experiment was arranged in a randomized complete block design of four replications. the plant proportions included pure culture of sorghum (sss); cowpea (ccc) and soybean (ggg) each in 12 rows; vs differe...

effects of seed priming by salicylic acid on yield and yield components of cowpea (vigna unguiculata) cultivar “parastou” were investigated under water deficit conditions. experiment was carried out as a split block design with three replications in 2008-2009 at research station of zanjan university. factors included drought stress as main factor with three levels (normal irrigation, applicatio...

Abstract Background The cowpea bruchid, Callosobruchus maculatus is the major postharvest insect pest of seeds in storage. This had led to huge losses and quality deterioration stored that serve as poor man’s meat lieu expensive source developing countries. research was carried out evaluate bioefficacy rice husk, maize cob, groundnut, pods against C. laboratory. Adult mortality, eggs laid, adul...

Seed coat crude extracts of white-coloured ITA-256, white and brown-coloured TVS-716, deep brown-coloured IT-90K and light brown-coloured Ife brown cowpea varieties were analyzed for the presence and amount of total phenol, tannin and flavonoid content. Crude extracts of the cowpea varieties were analyzed for antioxidant activity using the Thiobarbituric Acid (TBA) assay. The seed coat extracts...

We created a detailed model of the Maruca vitrata (F.) and cowpea [Vigna unguiculata (L.) Walp] system to study the possible evolution of resistance by the insect to transgenic insecticidal cowpea, which is under development. We focused on population dynamics and genetics in a region of west Africa. We simulated single-toxin and pyramided (two-toxin) cowpea and emphasized conservative, worst-c...
