Allometric equations, wood density and partitioning of aboveground biomass in the arboretum of Ruhande, Rwanda
(2021)There is growing interest in plantation forests throughout Africa because of their role in environment, economy and people's livelihoods. However, the contribution of planted forests to climate mitigation is poorly understood, ... -
Record of new host plants associated to the invasive mealybug species Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) in the Center and Littoral regions of Cameroon
(2021)The papaya mealybug (PM) is a known notorious polyphagous insect pest of many plant species and has always been found associated with a new host/s in newly invaded areas. This pest recently invaded West and Central Africa. ... -
Application of CRISPR/Cas for diagnosis and management of viral diseases of banana
(2021)Viral diseases are significant biotic constraints for banana (Musa spp.) production as they affect the yield and limit the international movement of germplasm. Among all the viruses known to infect banana, the banana bunchy ... -
Technological innovations for improving cassava production in sub-Saharan Africa
(2021-01)Cassava is crucial for food security of millions of people in sub-Saharan Africa. The crop has great potential to contribute to African development and is increasing its income-earning potential for small-scale farmers and ... -
Opportunities and challenges for biofortification of cassava to address iron and zinc deficiency in Nigeria
(2021-03)Nigeria is the world's largest producer of cassava (Manihot esculenta), and its production is important to the country's economy. Cassava's edible storage roots act as a critical staple food for over 180 million Nigerians. ... -
Emergence of Maruca vitrata as a major pest of food legumes and evolution of management practices in Asia and Africa
(2021-01)Legume pod borer, Maruca vitrata, has emerged as a major pest on food legumes in Asia and Africa. It is an oligophagous pest, feeding on over 70 species in Fabaceae. We examine the species complex in Asia, Africa, Oceania, ... -
Does agricultural cooperative membership impact technical efficiency of maize production in Nigeria: an analysis correcting for biases from observed and unobserved attributes
(2021)The formation of agricultural cooperatives has been widely promoted as an agricultural development policy initiative to help smallholder farmers cope with multiple production and marketing challenges. Using a nationally ... -
Impacts on greenhouse gas balance and rural economy after agroecology development in Itasy Madagascar
(2020)Rural development projects to develop sustainable agriculture need to be assessed before engaging smallholder farmers at large scale. Data on agricultural systems to produce food, provide income for smallholders and reduce ... -
Genotype by environment cultivar evaluation for cassava brown streak disease resistance in Tanzania
(2020-09)Cassava brown steak disease (CBSD), caused by Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV), is the most important biotic constraint to cassava production in East and Central Africa. ... -
Multiple small-effect alleles of Indica origin enhance high iron-associated stress tolerance in rice under field conditions in west Africa
(2020)Understanding the genetics of field-based tolerance to high iron-associated (HIA) stress in rice can accelerate the development of new varieties with enhanced yield performance in West African lowland ecosystems. To date, ... -
Enhancing farmers’ agency in the global crop commons through use of biocultural community protocols
(2021)Crop genetic resources constitute a ‘new’ global commons, characterized by multiple layers of activities of farmers, genebanks, public and private research and development organizations, and regulatory agencies operating ... -
Organic manure improves soybean response to rhizobia inoculant and p-fertilizer in northern Ghana
(2020-09)Inherently low concentrations of soil nutrients and erratic rainfall pattern in sub-Sahara Africa limit soybean response to rhizobia inoculant and P-fertilizer. The study was conducted to: (i) improve soybean response to ... -
Carotenoid profile and functional properties of flour blends from biofortified maize and improved soybean varieties for product developments
(2021)Biofortified maize has received increased attention from a nutraceutical perspective because of its bioactive phytochemical components, including carotenoids. However, biofortified maize is limiting in some amino acids ... -
Simple sequence repeat-based mini-core collection for white Guinea yam (Dioscorea rotundata) germplasm
(2021)A core subset with a small number of accessions representing the genetic diversity of the base collection plays a vital role in facilitating efficient utilization of plant genetic resources. This is particularly relevant ... -
Genotype by environment interaction on resistance to cassava green mite associated traits and effects on yield performance of cassava genotypes in Nigeria
(2020-09-04)Cassava is the main source of carbohydrate for over 70% of the people in Nigeria, the world’s largest producer and consumer of the crop. The yields of cassava are, however, relatively low in Nigeria largely due to pests ... -
Harvesting time and roasting effects on colour properties, xanthophylls, phytates, tannins and vitamin C contents of orange maize hybrid
(2020)Biofortified maize varieties form an essential part of a nutritious diet; available evidence suggests that different processing methods may affect the final food products. The study aimed to evaluate the effects of processing ... -
Quantitative assessment of trace and macro element compositions of cassava (Manihot esculenta) storage roots enriched with B-Carotene as influenced by genotypes and growing locations
(2020)Cassava’s important mineral contents depends on some factors, including genetic and growing locational factors. The study aimed to evaluate the influence of genotype and growing locations on the mineral concentrations in ... -
