Classical biological of key horticultural pests in Africa: successes, challenges, and opportunities
(2022-10)Classical biological control (CBC) is considered a safer and more sustainable alternative for management of alien-invasive species. This review presents recent advances in CBC of key horticultural insect pests using parasitoids in Africa. Several CBC programs have been undertaken targeting different insect pests of both fruits and vegetables, largely yielding outstanding success. Key obstacles impeding CBC and opportunities that could promote CBC in Africa are outlined. Also, very brief highlights ... -
Evaluation of elite and local African yam bean cultivars for yield and yield-related traits
(2022-08-12)The variability in African yam bean (AYB) accessions with respect to yield and other agronomic traits were studied for two cropping seasons (2012 and 2013) in field experiments to evaluate the growth, yield and yield components of 36 AYB accessions. The accessions differed significantly (P ≤ 0.05) in the traits studied. In 2012 Pearson correlation coefficients indicated that seed yield had significant (P ≤ 0.01) and positive relationships with total pod weight per plant (r = 0.80**), number of ... -

Assessment of quantitative and qualitative losses of stored grains due to insect infestation in Ethiopia
(2020-12)This study was designed to determine the quantitative and qualitative losses of stored grains that arise from insect infestation in three districts of southwestern Ethiopia. One district was selected from each zone based on the production potential of the target crops (maize, sorghum, wheat and fababean). A total of 240 farmers’ stores from all districts were randomly selected. The grain samples used in the present study were stored for 5 different time periods, ranging from 1 to 5 months and from ... -
Optimizing root yield of cassava under fertigation and the masked effect of atmospheric temperature
(2020-09)BACKGROUND Fertigation is a rare and an expensive method of fertilizer application to cassava, and hence there is a need to optimize its efficiency for profitability. This study's objective was to optimize root yield of cassava through fertigation using a logistic model. RESULTS The field treatments were six fertigation concentrations against three cassava varieties, selected according to their maturity period. The logistic model predicted 52%, 116% and 281% benefit of fertigation for the varieties ... -
Effets des precedentes plantes de couverture sur la production de l'igname en zone de savane au Benin et au Togo
(2005)L'igname (Dioscorea spp.), est généralement cultivée sur défriche de jachère longue pour bénéficier du niveau élevé de fertilité de sol mais l'augmentation de la pression démographique entraîne une la réduction générale de la durée des jachères. Dans le but de mettre au point des systèmes de production durables à base d'igname des essais ont été menés respectivement à Gobé au centre du Bénin et à Laouno et Tchébébé au centre du Togo en vue d'évaluer l'effet des jachères des légumineuses Aeschynomene ... -
Genome-wide association analyses reveal the genetic basis of biomass accumulation under symbiotic nitrogen fixation in African soybean
(2020-02)Symbiotic nitrogen fixation (SNF) increases sustainability by supplying biological nitrogen for crops to enhance yields without damaging the ecosystem. A better understanding of this complex biological process is critical for addressing the triple challenges of food security, environmental degradation, and climate change. Soybean plants, the most important legume worldwide, can form a mutualistic interaction with specialized soil bacteria, bradyrhizobia, to fix atmospheric nitrogen. Here we report ... -
Genetic dissection of yield associated traits in a cross between cowpea and yard-long bean (Vigna unguiculata (L.) Walp.) based on DArT markers
(2020-06-19)Both cowpea and yard-long bean belong to Vigna unguiculata ssp. unguiculata but have diverged through human induced evolution in sub-Saharan Africa and Asia, respectively. To map the quantitative trait loci (QTLs) for yield associated traits and derive new lines that may combine the attributes of both types, we developed a F2:3 mapping population derived from a cross between cowpea line TVu2185 and yard-long bean line TVu6642. Using DArT markers, a total of 30 QTLs accounting for 1.8–13.0% phenotypic ... -
Evaluation of Mchare and Matooke Bananas for Resistance to Fusarium oxysporum f. sp. cubense Race 1
(2020-09)Fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc) race 1, is a major disease of bananas in East Africa. Triploid East African Highland (Matooke) bananas are resistant to Foc race 1, but the response of diploid (Mchare and Muraru) bananas to the fungus is largely unknown. A breeding project was initiated in 2014 to increase crop yield and improve disease and pest resistance of diploid and triploid East African Highland bananas. In this study, eight Mchare cultivars ... -
Rendement en feuilles et racines de trois variétés améliorées de manioc (Manihot esculenta Crantz) en réponse aux fertilisants organo-minéraux et à la récolte des feuilles au Sud-Ouest du Nigeria
(2020-05)L’étude a été menée dans l’objectif d’évaluer la production de trois variétés améliorées de manioc en réponse à la récolte des feuilles et aux fertilisants NPK, compost et Compost-NPK. L’essai a été fait selon le dispositif en split-split plot, à blocs aléatoires complets à trois facteurs et trois réplications. Les récoltes ont été réalisées à 3 mois et 5 mois après la plantation. La récolte finale a été faite à 12 Mois Après la Plantation (MAP). Le résultat montre qu’une différence non significative ... -
Diversity and structure of prokaryotic communities within organic and conventional farming systems in central highlands of Kenya
(2020)Management practices such as tillage, crop rotation, irrigation, organic and inorganic inputs application are known to influence diversity and function of soil microbial populations. In this study, we investigated the effect of conventional versus organic farming systems at low and high input levels on structure and diversity of prokaryotic microbial communities. Soil samples were collected from the ongoing long-term farming system comparison trials established in 2007 at Chuka and Thika in Kenya. ... -
