Contribution a la gestion agroecologique de Maruca vitrata Fab. et d'autres insectes ravageurs majeurs de la culture du niebe (Vigna unguiculata L. Walp.) dans les regions de Zinder et Maradi au Niger
(Universite Dan Dicko Dankoulodo De Maradi, 2020)Au Niger, le niébé (Vigna unguiculata L. Walp.) est une culture alimentaire importante mais son rendement est bas en raison de plusieurs contraintes biotiques et abiotiques. L’objectif de cette thèse est d’améliorer le ... -
Innovation intermediation in a digital age: broadening extension service delivery in Ghana
(Wageningen University and Research Center, 2020)Classical extension focuses on linear transfer of technology. Globally, and in Ghana particularly, we have seen attempts to address the linearity of classical extension with the shift to broader extension service delivery ... -
Genetic analysis of tuber yield and quality traits in white yam (Dioscorea rotundata Poir)
(University of Ghana, 2019-12)The genetic progress in tuber yield and quality attributes of yam is constrained by prolonged breeding cycle, complex ploidy (2n=40, 60, 80), high heterozygousity, complex flowering pattern (dioecois and monoecious flowering ... -
Interseeding timing of cowpea (Vigna unguiculata L. Walp.) living mulch on weed diversity, physical soil properties and performance of maize (Zea mays L.)
(University of Development Studies, 2019)This trial was conducted to determine cowpea living mulch and maize maturity type effect on soil physical properties, maize yield and weed management. The study was a 3 x 4 factorial experiment laid out in Randomised ... -
Evaluation of starches from selected yellow and white flesh cassava roots for noodles production
(Federal University of Agriculture, Abeokuta, 2020)Cassava starch has been prospected in many food products manufacture. However, its suitability for making starch noodle has not been reported. Hence, this study was conducted to determine cassava starch‘s suitability in ... -
Productivity, water use and climate resilience of alternative cocoa cultivation systems
(Georg-August-University of Gottingen, 2017-12)Global demand for cocoa beans is projected to keep rising while future production is likely to be limited by climate variability and change. Over 70% of the global cocoa supply comes from West Africa, a region expected to ... -
Efficacy of cassava-maize intercrop on weed control and yield of component crops
(University of Ilorin, 2019)Low yield of maize/cassava intercrop is majorly due to some identified constraints like poor density of component crops, inappropriate application of fertilizer and weed infestation. This study was conducted in Otukpo-Icho, ... -
Genetic analysis of resistance to Radopholus similis in Banana
(Makerere University, 2019-12)Banana is an important crop worldwide mostly grown in tropical and subtropical regions, of annual production is 145 million metric tons valued at 26.5 billion Euros. Banana production is threatened by various constraints ... -
Responses of the Ethiopian fruit fly, Dacus ciliatus (Diptera, Tephritidae) to colored rectangles, spheres, and ovoids
(2004)On the Mascarene Islands, the Ethiopian fruit fly, Dacus ciliatus Loew, is one of the major frugivorous pests of Cucurbitaceae. Both visual and olfactory signals involved in the host location process need to be evaluated ... -
Genetic analysis of host plant resistance to the cassava mosaic disease
(2002)The genetic control of resistance to the cassava mosaic disease (CMD) in some African landraces, their relationship with the widely used resistant genetic stock, clone 58308, and molecular markers associated with resistance ... -
Economic evaluation of adoption of improved soybean production and utilization technologies in Kaduna and Kano States Nigeria: P.hD. thesis
(2006)Low yield, persistent pod shattering and susceptibility 10 pests and diseases characterize the cultivation of traditional soybean varieties in Nigeria. Research has, however, developed new improved variety of soybeans, ... -
Capital market operations in an emerging economy: the case of Nigeria
(2008)One of the key challenges facing big businesses is how to secure the huge financing they need to invest in their businesses. From banking, insurance, pharmaceuticals, conglomerates, oil and gas companies and every other ... -
Gender dynamics in smallholder vegetable production: insights from Tanzania
(Freie Universität Berlin, 2017)The presented study investigates gender dynamics in vegetable producer’s households as related to labor, income and expenditure allocation – as field that has not yet been sufficiently covered by research. It is conducted ...
