Cowpea is a key cash crop and also a staple food for millions of people in West and Central Africa. Cowpea trade is severely hampered by storage insects especially the cowpea weevil. The Purdue Improved Cowpea Storage (PICS) project was started in Nigeria in 2008 on a pilot basis in the states of...

Cowpea is a major food and cash crop in northern Nigeria, providing nutritious grain and a less expensive source of protein for both the rural poor and urban consumers. A number of improved varieties have been developed combining diverse plant type, and different maturity periods, with resistance...

A field study was conducted to determine the rate of genetic improvement in grain and fodder yields of cowpea genotypes developed in the Nigerian Sudan savannas from 1970 to 2004. Results showed that grain yield ranged from 568 kg/ha for an old variety TVX3236 to 1851 kg/ha for a recently release...

Current strategies to control insect pest problems in cowpea include, on the preventive side, host plant resistance and conservation biological control. Because very often these management options alone cannot provide adequate control, curative measures need to be taken, which include augmentativ...

Scarcity and/or high cost of healthy seed yams are the greatest constraints in yam production in Nigeria and probably across the West African Yam belt. Scientists at the National Root Crops Research Umudike developed the yam minisett technique of seed yam production in 1982 but nearly three decad...

L'interaction des plusieurs contraintes, à savoir les maladies et ravageurs du manioc, les pratiques culturales inadéquates, la faible fertilité des sols, etc. contribuent à la baisse de la productivité du manioc. Il a été constaté à Luputa et Ngandajika que les champs des agriculteurs y compris ...

Cassava (Manihot esculenta Crantz) is the second most important food crop after rice, the staple in Sierra Leone; it is also the most important root and tuber crop. It is followed by sweet potato (Ipomoea batatas L.), yam (Dioscorea spp.), which forms part of the traditional farming system and ha...

Through a combination of conventional and new approaches, root and tuber improvement programs have developed improved cassava varieties that combine multiple pest and disease resistances with superior postharvest qualities, and improve the yield potential by more than 50%. This new generation of ...

Anoplolepis tenella Santschi is an afrotropical ant widely distributed in the forest zones of Central Africa. It is the most frequent species associated with the African root and tuber scale (ARTS) Stictococcus vayssierei (Hemiptera: Stictococcidae), an afrotropical insect that infests a wide ran...
