View article: Groundnut Host Plant and Vector Aphid (<i>Aphis craccivora</i>) Interaction in the Transmission of Groundnut Rosette Disease as a Basis for Physiological Studies
Groundnut Host Plant and Vector Aphid (<i>Aphis craccivora</i>) Interaction in the Transmission of Groundnut Rosette Disease as a Basis for Physiological Studies Open
Groundnut (Arachis hypogaea L.) is an important food crop in sub-Saharan Africa. Among the major causes for low yields is the susceptibility of cultivated varieties to the Groundnut Rosette Disease (GRD). The Groundnut Rosette is a viral d…

A Comprehensive Review of Aflatoxin in Groundnut and Maize Products in Africa: Prevalence, Detection and Mitigation Strategies Open
Aflatoxins are a toxic secondary metabolite, mainly produced by the fungi Aspergillus flavus and A. parasiticus. Aflatoxin contamination of food is a global concern, as they are carcinogenic, mutagenic and teratogenic. Groundnuts and maize…

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa Open
Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yi…

AfriMTE and AfriCOMET: Enhancing COMET to Embrace Under-resourced African Languages Open
Despite the recent progress on scaling multilingual machine translation (MT) to several under-resourced African languages, accurately measuring this progress remains challenging, since evaluation is often performed on n-gram matching metri…

Soil zinc fertilisation does not increase maize yields but improves nutritional quality Open
AIMS Fertilisation of crops with zinc (Zn) is considered important to enhance agricultural productivity and combat human deficiencies in sub-Saharan Africa. However, it is unclear on which soils Zn fertilisation can lead to higher yields a…

Functional Biology and Molecular Mechanisms of Host-Pathogen Interactions for Aflatoxin Contamination in Groundnut (Arachis hypogaea L.) and Maize (Zea mays L.) Open
Aflatoxins are secondary metabolites produced by soilborne saprophytic fungus Aspergillus flavus and closely related species that infect several agricultural commodities including groundnut and maize. The consumption of contaminated…

Knowledge, Attitude and Practice of Malawian Farmers on Pre- and Post-Harvest Crop Management to Mitigate Aflatoxin Contamination in Groundnut, Maize and Sorghum—Implication for Behavioral Change Open
A knowledge, attitude and practice (KAP) study was conducted in three districts of Malawi to test whether the training had resulted in increased knowledge and adoption of recommended pre- and post-harvest crop management practices, and the…

Mitigating Aflatoxin Contamination in Groundnut through A Combination of Genetic Resistance and Post-Harvest Management Practices Open
Aflatoxin is considered a “hidden poison” due to its slow and adverse effect on various biological pathways in humans, particularly among children, in whom it leads to delayed development, stunted growth, liver damage, and liver cancer. Un…

Exploiting Genetic Diversity for Blast Disease Resistance Sources in Finger Millet (<i>Eleusine coracana</i>) Open
Finger millet blast, caused by Magnaporthe grisea, is the most important disease of finger millet in East Africa. Diseased plants are significantly less productive, and most cultivars grown by farmers are susceptible to the disease. Fungic…

Effects of Compost Manure on Soil Microbial Respiration, Plant-Available-Water, Peanut (<i>Arachis hypogaea L</i>.) Yield and Pre-Harvest Aflatoxin Contamination Open
Peanut production in Zambia is often characterized by low yields and high aflatoxin incidence in harvested kernels. Soil amendments such as farmyard manure have shown potential to increase yields and reduce pre-harvest aflatoxin incidence.…

A Critical Review of Aflatoxin Contamination of Peanuts in Malawi and Zambia: The Past, Present, and Future Open
Peanut (Arachis hypogaea L.) is an important crop in Malawi and Zambia. The crop is valued for soil improvement in cereal-based cropping systems, for improving the livelihoods of farming households who consume it and also sell it for cash,…

Identification and Toxigenicity of<i>Aspergillus</i>spp. from Soils Planted to Peanuts in Eastern Zambia Open
It is not known which aflatoxigenic species are present in Zambia. Therefore, soil samples were collected during May to June 2012, at the end of the growing season in Eastern Province, from 399 farmers' fields that had been planted to grou…
