Cowpea (Vigna unguiculata) has relatively higher drought tolerance than other legume crops. It is widely grown in semi-arid regions, particularly in West Africa. One objective of the present study was to determine the effects of soil moisture stress on the length, dry matter and distribution of t...

Ten crop species were evaluated for their relative drought tolerance at the seedling stage. Healthy seeds of each crop were planted in wooden boxes of 130 cm length, 65 cm width and 15 cm depth, filled with 3 soil types (river sand, loamy sand and sandy loam) and watered daily. A week after germi...

A simple screening method was developed that accurately discriminates between drought and susceptible cowpea(Vigna unguiculata(L) walp). Wooden boxes (130 cm length. 65cm width. 15cm depth) made of 2.5cm thick planks were lined with polythene sheets, filled with a 12cm layer of soil and sand mixt...

Twelve cowpea (Vigna unguiculata) varieties were planted in wooden boxes of 130 cm length, 65 cm width, and 15 cm depth filled with sand and soil mixture (1:1) at 10 cm row to row and 5 cm plant-to-plant distances. The boxes were watered daily until the unifoliate leaves had fully expanded and th...

The parasitic weeds, Alectra vogelii Benth., and Striga gesnerioides (Wild.) Vatke, have become major yield-reducing factors in cowpea. Currently, Striga is more prevalent in the Sudan savanna and Sahelian regions and Alectra in the northern Guinea savanna and southern Sudan savanna regions of We...

Cowpea Vigna unguiculata (L.) Walp. is an important component in mixed cropping systems that are appropriate to the agro-ecological characteristics of the West African savannah. However, the contribution of cowpea to overall productivity of the systems is reduced by a number of insect pest specie...

Cowpeas suffer major yield losses due to insect pests, so insect resistant cowpea varieties are being developed to minimize insecticide use in integrated pest management. Experiments during the cropping seasons of 2002–2004 at Kano, Nigeria, evaluated four cowpea varieties and five combinations o...

Cowpea (Vigna unguiculata [L.| Wulp.) is primarily grown in dry regions in the tropics, particularly in sub-Saharan Africa. Drought is important among several yield-reducing factors. Nine hundred cowpea accessions from the Genetic Resources Unit of IITA were evaluated for drought tolerance in a f...
