This study investigated the inheritance of resistance to Fusarium oxysporum f.sp. tracheiphilum (Fot) in cowpea lines. Resistant and susceptible cowpea lines were crossed to develop F1, F2 and backcross populations. Reaction to Fot was evaluated in 2015 and 2016 using seed soak and modified root‐...

After insects, mites are the major arthropod pests that inhabit stored agriculturalproducts worldwide. To determine the acarofauna that infests cowpea, maize, paddyrice and sorghum in Benin (West Africa), surveys were conducted in some principalmarkets (Dantokpa, Glazoue and Parakou) of this coun...

In view of the lack of information on the use of herbicides in polycultures including non-commercial crop species, 2 expt. were designed to identify herbicides and doses suitable for crop associations including cassava. A total of 6 products were tested single or in mixtures having been chosen fo...

S. gesnerioides (Willd) Vatke is a major biological constraint to cowpea production in the dry savanna of sub-Saharan Africa. Yield losses caused by S. gesnerioides in these regions are estimated in millions of tons annually, and prevalence of Striga soil infestation is steadily increasing. The a...

Cowpea is an important crop for food security, as it is a primary source of protein and cash income for farmers in the dry savanna areas of Sub-Saharan Africa. Improved varieties should contain reasonable amounts of protein in the grains, and to ensure this, timely and cost-effective analytical m...
