Low soil nutrient tolerance and mineral fertilizer response in White Guinea Yam (Dioscorea rotundata) genotypes
(2021)Yam (Dioscorea spp.) is a major food security crop for millions of resource-poor farmers, particularly in West Africa. Soil mineral deficiency is the main challenge in yam production, especially with the dwindling of fallow ... -
Gender roles in sourcing and sharing of banana planting material in communities with and without banana bunchy top disease in Nigeria
(2021)Banana bunchy top disease (BBTD) is the most devastating disease of banana and plantain (Musa spp.). The disease spreads through the use of infected vegetative propagules and the banana aphid (Pentalonia nigronervosa) is ... -
Genetic parameter estimation and selection in advanced breeding population of white Guinea yam
(2021)White Guinea yam (Dioscorea rotundata Poir.) is an important tuber crop grown extensively in tropical regions of West African yam belt. Tuber yield, dry matter content, and tolerance to yam mosaic virus are key traits used ... -
Auxin signaling and vascular cambium formation enables storage metabolism in cassava tuberous roots
(2021)Cassava storage roots are among the most important root crops worldwide and represent one of the most consumed staple foods in Sub-Saharan Africa. The vegetatively propagated tropical shrub can form many starchy tuberous ... -

Evaluation of improved cassava genotypes for yield and related traits for a better breeding strategy under different agroecologies in Nigeria
(2021)This study aimed at determining shoot and root characteristics of cassava as affected by root yield and the influence of soil moisture on vegetative growth and yield. Thirty cassava genotypes were evaluated for morphological ... -
Diversite des trajectoires de l'agriculture biologique au Cameroun
(2020)Dans un contexte de renouvellement des enjeux technologiques de l'agriculture africaine, l'agriculture biologique représente une option de transition potentielle. Cette étude analyse les conditions de son développement au ... -
Nematodes and food security in sub-Saharan Africa
(International Institute of Tropical Agriculture, 2020)Across the tropics pests and diseases can plague crop production. Nematode pests are no different but in general, there is limited understanding or recognition of nematode pests in the tropics and in subSaharan Africa. Yet ... -
Optimizing sowing density-based management decisions with different nitrogen rates on smallholder maize farms in northern Nigeria
(2021-01-18)In this study, the CERES-Maize model was calibrated and evaluated using data from 60 farmers’ fields across Sudan (SS) and Northern Guinea (NGS) Savannas of Nigeria in 2016 and 2017 rainy seasons. The trials consisted of ... -
Disease incidence and severity in cowpea lines evaluated for resistance to single and multiple infections of endemic viruses in Nigeria
(2020-10)Cowpea (Vigna unguiculata (L.) Walp) is susceptible to several viruses in West Africa. Cowpea viral diseases are mainly controlled through the use of resistant cultivars. Co-infection with more than one virus is frequent ... -
Maize–legume strip cropping effect on productivity, income, and income risk of farmers in northern Ghana
(2021)Maize (Zea mays L.)–legume intercropping is common cropping system among smallholder farmers in West Africa. However, little is known about the income risk reduction associated with maize–legume strip cropping in West ... -
Genetic diversity of white yam (Dioscorea rotundata Poir) accessions maintained in tissue culture and cultivated in field using Simple Sequence Repeat (SSR) Markers and Morphological Characterization
(2021)Dioscorea rotundata is a staple food crop for millions of people in the tropical and subtropical regions. In vitro germplasm conservation is a very useful tool in yam improvement strategies but very little is known about ... -
Kilimo kinachohimili mabadiliko ya tabianchi: maamuzi kumi muhimu ya kufanya kwa kuzingatia taarifa za hali ya hewa
(International Institute of Tropical Agriculture, 2021) -
Data set of smallholder farm households in banana-coffee-based farming systems containing data on farm households, agricultural production and use of organic farm waste
(2021-04)The data was collected in the Karagwe and Kyerwa districts of the Kagera region in north-west Tanzania. It encompasses 150 smallholder farming households, which were interviewed on the composition of their household, ... -
Enhancing drought tolerance and Striga hermonthica resistance in maize using newly derived inbred lines from the wild maize relative, Zea diploperennis
(2021)Recurrent drought and Striga hermonthica (Del.) Benth parasitism constrains maize production in sub-Saharan Africa (SSA). Transfer of resistance genes from wild relatives can improve resistance to drought and Striga in ... -
Validation of diagnostic markers for streak virus disease resistance in maize
(2021)Maize streak virus (MSV) is responsible for streak disease of maize and poses a serious threat to maize production in sub-Saharan Africa. Polygenic resistance to MSV has become an essential requirement in modern maize ... -
Genetic diversity and population structure of early and extra-early maturing maize germplasm adapted to sub-Saharan Africa
(2021)Background Assessment and effective utilization of genetic diversity in breeding programs is crucial for sustainable genetic improvement and rapid adaptation to changing breeding objectives. During the past two decades, ... -
Agro-ecology, resource endowment and indigenous knowledge interactions modulate soil fertility in mixed farming systems in central and western Ethiopia
(2021)Site‐specific soil fertility management requires a fundamental understanding of factors that modulate soil fertility variability in the local context. To verify this assumption, this study hypothesized that soil fertility ... -
Prevalence of aflatoxin- and fumonisin-producing fungi associated with cereal crops grown in Zimbabwe and their associated risks in a climate change scenario
(2021)In most sub-Saharan African countries, staple cereal grains harbor many fungi and some produce mycotoxins that negatively impact health and trade. Maize and three small grain cereals (sorghum, pearl millet, and finger ...
