Manageable agronomic practices in organic production of cowpea (Vigna unguidulata [L. Walp] in a mixed culture with sorghum
Comparative study of the effects of steam and solar heat treated cowpea seed on the development and control of Callosobruchus maculatus (F.) (Coleoptera: Bruchidae)
Many farmers face urgent problems of making sure there is enough food for their families for the whole year and earning sufficient income. Population growth and the increasing size of cities and towns mean that the amount of land available to grow food for each family is decreasing. Yields are not always high and the prices of agricultural products are generally declining.

Bean anthracnose, caused by the fungus Colletotrichum lindemuthianum, is a major disease of beans (Phaseolus vulgaris L.), causing serious crop loss in many parts of the world. In 1921, M. F. Barrus of Cornell University demonstrated that bean anthracnose is seedborne. This information resulted in the widespread use of anthracnose-free seed and a subsequent decline in the ocurrance of bean anthracnose in the United States.
Fumigant Toxicity of Crushed Bulbs of Two Allium Species to Callosobruchus maculatus (Fabricius) (Coleoptera: Bruchidae)
Fumigant toxicity of crushed fresh bulbs of Allium sativum L. and A. cepa L. to the Callosobruchus maculatus (Fabricius), a major pest of stored cowpea (Vigna unguiculata (L.) Walp.) seeds was assessed under laboratory conditions in Akure, Nigeria. In the tests, 20 g of infested cowpea seeds were suspended in a piece of muslin cloth, over an amount of crushed bulb in a container with a tightly fitted lid. Adult emergence was completely prevented from freshly laid eggs of C.
