Journal Article 1993

Autor: Shapiro, Barry I. Sanders, J.H. Reddy, K.C. Baker, T.G.

This study modeled the introduction of new early cultivars of millet and cowpea, higher cowpea densities, and various fertilization strategies. Model results were then compared with farmer behaviour before and after the availability of these new technologies. The model correctly identified the tw...

A field study of cowpea, soybean and maize was made at Ibadan, Nigeria, to determine the uptake of mineral nutrients and quantities removed in crop residues and seed. Concentrations of N, the major cations (K, Ca, Mg and Na) and major anions (P, S and Cl), and the micronutrients (Fe, Mn, Zn and C...

Strains of Xanthomonas campestris pv. vignicola (Xcv), isolated from cowpea leaves with blight or minute pustules and collected from various geographic areas, were selected on the basis of pathological and physiological features. All strains were analyzed for genotypic markers by two methods: rib...

Cowpea is the most important grain legume and fodder crop in the dry savannas of Africa. Grown on more than 12.5 million hectares, grain yields from improved varieties are higher than local varieties, but require 2 to 3 insecticide sprays to control major pests compared to local varieties. Losses...

Autor: Sanginga, N.

Nitrogen (N) has been gradually depleted from West African soils and now poses serious threats to food production. Many ways of increasing N supply (e.g. judicious use of inorganic fertilizers and nitrogen-fixing plants) have been tried in West African farming systems. Herbaceous and woody legume...

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...
