Area of Study: Effect of Scattered Acacia Tortilis and Acacia Nilotica Trees on Selected Soil Physio-Chemical Properties and Yield of Sorghum at Babile District, Eastern Ethiopia

Scattered Acacia tortilis and Acacia nilotica trees are purposively managed by farmers as a parkland agroforestry practice for addition of nutrient to the soil through nitrogen fixation, litter addition, nutrient uptake from below the reach of crop roots and moderating soil environment. There is limited scientific studies in the area on tree-crop interaction and quantity of nutrient added to the soil due to those trees in the study area. The study aimed to determine the effects of Acacia tortilis and Acacia nilotica trees on selected physicochemical properties of soil at different distance and soil depth, and to assess effect on yield and yield components of sorghum grown at different distances from the tree trunk. The finding expected with positive tree-crop interaction through which the tree can add more nutrient to the soil that might be increase crop yield leading for food security for the farmer and encourage sustainably manage trees on farm land. The information can also help in designing sustainable land use that could enhance productivity of crops while maintaining and improving the resource base and resistance for climatic event.

Mr. Aboye hopes to be an agricultural and natural resource researcher using his knowledge to enhance agricultural production through managed nature in the country. I would like to working in an international research environment, which will give me a privilege of meeting and associating with people from all over the world having different points of view to be immerse in a society with a global outlook.

Cette recherche est une réponse de la dégradation de la ressource de base et à la baisse continue des rendements en l’occurrence le maïs, principale culture et aliment de base de la population de la région des Savanes au Togo à tel point que la sécurité alimentaire semblent se limiter à sa disponibilité spatio-temporelle mais aussi à son accessibilité pour les ménage.  Au terme de cette thèse, les causes de la variabilité spatiale des rendements en grain du maïs sont connues, la fertilité endogène des sols de la région des Savanes du Togo est actualisée ; des pratiques de gestion agronomique pour la production du maïs dans la région sont développées sur la base de l’interface sol-climat-végétal; des recommandations de pratiques de gestion techniquement, socialement et économiquement justifiées sont faites pour la production du maïs dans la région.

Mouhamadou’s objectif de carrière est avant tout d’atteindre l’objectif de la thèse avec des résultats attractifs, qui me fourniront des connaissances scientifiques solides me permettant de mettre en place des programmes de recherche-développement au niveau national, régional et même international.

Mr. Kehinde Afeez OJENIYI — NIGERIA

Masters Program: University of Mohammed VI Polytechnic (UM6P), Benguérir, Morocco

Area of Study: Assessment of Maize Yield Gap and Nutrient Use Efficiencies through the Application of National and Regional Fertilizer Recommendations as Straight and Compound Fertilizer in Mid-belt Nigeria.

The lack of advanced technology in the blending company has led to instances of segregation in the blended fertilizer, as a consequence, certain nutrient application rates might not adequately meet the requirements of plant. With straight fertilizer, each nutrient can be applied at recommended rate and time of plant uptake. Efficient fertilizer management practices have the potential to significantly increase maize yields in the mid-region of Nigeria beyond the levels achieved through current farming methods. This research aimed to assess the effects of national and regional fertilizer recommendations, applied as straight and compound fertilizers, on soil properties, nutrient efficiency, and maize yield in the mid-belt region of Nigeria. Despite the intention of blend fertilizers to reduce costs and create customized formulas, the findings revealed that the split application of nutrients enhanced nitrogen uptake efficiency and resulted in higher maize grain yields compared to the NPK blend application, emphasizing the need for adopting regional fertilizer recommendation applied as split using straight fertilizers to increase maize yields and improved economic returns in the mid-belt region of Nigeria.

Mr. Ojeniyi’s, ultimate career goal is to become a leading agronomy researcher, making impactful changes in agricultural practices including integrated nutrient management, fertilizer recommendations, crop nutrition, and contributing to improved food security and sustainability, not only in Nigeria but also globally. He intends to proceed to enrol for a Ph.D. after the master program to increase my knowledge and research experience in agronomy.

Ms. Rosebell Achieng OWUOR — KENYA

Doctorate Program: Maseno University, Kenya

Area of Study: Comparative Economic Analysis of Tea Yield Response to Nitrogen Fertilizer Use and Plucking Intervals in East Africa

Currently, blanket input recommendations for nitrogen (N) fertilizer application and plucking intervals are contingent on response trials conducted Kenya. Hence, locations where these recommendations are exported fail to replicate results similar to the trial locations because of the heterogeneous aspects of the locations. The objectives of Rosebell’s research are to determine site-specific optimal economic N fertilizer rate and harvesting intervals of tea clone TRFK 6/8 in selected tea-growing areas in East Africa (i.e., Kenya, Tanzania, and Rwanda), and to determine the economically efficient site-specific interaction effects of various nitrogen fertilizer rates and plucking intervals. Information from this study will enable the formulation of recommendations that are site-specific and act as a guide for fertilizer rate and plucking intervals recommendation in different areas as a less expensive alternative to trials for all released clones in all regions, thus realizing cost savings in adaptive research.

Her immediate goal is to finish her doctoral dissertation and publish in prestigious journals and ensure these findings assist scientists, academics and farmers to economically optimize tea output from agronomic inputs, and ultimately precision farming for different tea clones. She is looking forward to collaborating with a global policy and research organization that will provide her the opportunity to put her knowledge and experience to use for issues impacting precision agriculture. Her goals for the future are to establish herself as a prominent academic lecturer in agricultural economics, and a researcher dedicated to providing farmers with tools for sustainable and competitive optimum economic crop productivity.

Mr. Maurice Njiandoh MBEBOH  — CAMEROON

Doctorate Program: University of Buea, Cameroon

Area of Study: Evaluating the Effects of Plant Growth-Promoting Microorganisms and Plant Bioactive Materials on Soil Fertility, Plant Nutrition and Soybean Grain Yield

Growing up in a subsistence farming household and community, Mr Mebeboh had first-hand experience of the challenges involved in agricultural production, which stimulated a natural desire to become an agronomist with special interest on soil fertility management and plant nutrition. His Ph.D. Thesis, “Evaluating the Effects of Plant Growth-Promoting Microorganisms and Plant Bioactive Materials on Soil Fertility, Plant Nutrition and Soybean Grain Yield” aims to provide the best bet management practices that can restore the soil microbiota and functionality, enhance soybean nutrition as well as grain yield.

The specific objectives of this research are principally focused on formulating consortia of effective microbial inoculants and suitable bioactive plant materials that are adapted to the specific needs of farmers, and promoting their effective use for managing major abiotic (nutrient deficiency) and biotic (pests) constraints under sustainable intensification, within the nexus of integrated soil fertility management. This research will foster sustainable development by improving plant nutrition and protection, which will enhance soybean productivity, increase farmers’ income and welfare, reduce hunger and malnutrition and decrease food and nutrition insecurity especially in Sub-Saharan Africa. 


Masters Program: Hawassa University, Ethiopia

Area of Study: Fractionation and availability of phosphorus in acid soils under different land uses of Dalle and Wonsho district of Sidama Region, Ethiopia

Mr. Tadesse’s study is aimed to quantify the various labile and stable pools of inorganic and organic P in acidic soils of Dale and Wonsho woredas, Sidama region. Although little is known about Ethiopian soil P distribution, transformations, and fertility in that P availability in the country’s dominant soils is relatively low, the low levels of plant-available P are an inherent limitation to crop production on most Ethiopian soils, yet the nature of soil P has not been assessed across the wide range of soil types that are present across the country. A complete budget of the P forms present in soil is required to comprehend the fate of applied P fertilizers because available P in soil is not the only entity that P may reside in or fertilizer enters into. This can be done by identifying the labile and non-labile soil pools at the study area particularly (Dale and Wonsho Sidama Ethiopia) as well as across the country and abroad with similar soil types. Evaluating the effects of different land uses on  soil phosphorus pools and assessing soil phosphorus availability and soil properties under different land uses are essential, and therefore this study  initiated to solve these  problems in the study area.

Moges’s future goal is to improve agricultural production and productivity by implementing healthy and quality agricultural research system and academia to help change farmers life through best soil management practice and increasing soil fertility by keeping P-fertilizer quality to help agricultural sustainability for the development of the country.
