Graduate programs in agriculture in developing countries such as in Ethiopia are often designed in cognizance of the need for skilled manpower for agricultural development. In Ethiopia, the contribution of graduates of agricultural graduat…
We assess the potential and constraints of increased sorghum and pearl millet production to enhance food security and livelihoods in central Tanzania. These dryland cereals show a high potential to contribute to local food security. The st…
Concern about food security has increased because of a changing climate, which poses a great threat to food crop productivity. Climate change projections from the Coupled Model Inter-comparison Project phase 5 (CMIP5) and crop models were …
Watamu coastlineis a major attraction site for tourist and also a source of income for the local people. However, the shoreline has been changing due to erosion. This study sought to find the trend of shoreline changes, and the factors att…
This study uses old aerial photographs, current high resolution satellite images and ground truthing to analyze the patterns and dynamics of Mida Creek mangrove forest changes over 41 years from 1969-2010. A non-distractive method was used…
A field study was carried out to evaluate the effects of tillage practices on soil physical properties in Mwala district, Eastern Kenya, duringthelongrains(LR)andshortrains(SR)of2012/13.Thetreatmentswerediscploughing(DP),discploughingandharr…
A soil profile representative of typical soils of Mwala District, Kenya, was dug to study its morphology, soil physico-chemical characteristics and to classify it using two internationally known soil classification systems. Disturbed and u…
Soil water conservation through tillage is one of the appropriate ways of addressing soil moisture deficit in rainfed agriculture. This study evaluated the effects of tillage practices on soil moisture conservation and crop yields in Mwala…
Legumes like faba bean (Vicia faba L.) and soybean (Glycine max L.) is able to fix 20–60 kg N ha 1 under tropical environments, but these amounts are significant for the succeeding cereal to meet the N requirement for economically attracti…
The biological N2-fixation in faba bean on subsequent nitrogen fertilizer requirement of highland maize varieties would be useful in guiding application of additional nitrogen fertilizer in cropping sequence. Maize planted following faba b…
Inappropriate land use can deplete nutrient contents of crop land that leads to reduce nutrient concentrations and productivity. However, monitoring nutrient status of crop land can help producer take appropriate remedial measures before s…
Pastoral livestock production in Kenya is subject to unpredictable rainfall and drought occurrences. These adverse climatic conditions have led to vulnerable and insecure pastoral livelihoods. Despite the potential to alleviate food insecu…
Land use and land cover change in River Lwiro micro-catchment was assessed for the period 1987-2010 using satellite imagery of Landsat 5 and 7. Images were clustered into four categories: forest, built-up areas, wetland and small scale far…
Low-input pastoral production systems provide up to 90 % of livestock and livestock products consumed in Uganda. However, pastoral communities are increasingly faced with the challenge of meeting their livestock needs in terms of forage, a…
The study aimed at forecasting small Haplochromine species locally known as Kambuzi yield in Malaŵi, based on data on Lake Malombe fish catches during the years from 1976 to 2011. The study considered Autoregressive (AR), Moving Average (M…
The paper deals with the surplus production models of Verhulst Schaefer that were applied to the small haplochromine cichlids fishery to investigate the sustainability properties of the stock and management of the fishery. The basic object…
Maize cob rot caused by Fusarium graminearum and Stenocarpella maydis affects grain yield and quality. The objective of this study was to investigate the appropriateness of multiple infection as a selection and breeding strategy for multip…
The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% yield loss in sorgh…
Sorghum (Sorghum bicolor) is an important cereal food crop in semi-arid tropics, but its productivity is curtailed mainly by insect pests and diseases. The African stem borer, Busseola fusca Fuller (Lepidopteran: Noctuidae), is among the m…
Chambo has potential of improving fishers’ socio-economic status in Malawi. The paper examines Chambo value chain whose findings will improve fish marketing by actors along the chain. Quantitative value chain analysis used, investigated in…
Lake Malawi Tilapia (chambo) fish species is widely consumed and forms the most important commercial fishery in Lake Malawi. However, as a highly perishable commodity, knowledge regarding how long fresh fish would remain in acceptable and …
Post-harvest losses caused by the larger grain borer (LGB, Prostephanus truncatus) aggravate food insecurity among small-scale farmers. Host plant resistance is a method of LGB control which should be prioritized in order to reduce these l…
Breeding progress for drought tolerance in maize has been slow since drought tolerance is a complex trait controlled by many genes. Breeders improving maize for drought tolerance have therefore been using secondary traits and selection ind…
In-vitro studies were conducted to determine the anthelmintic activity of ethanolic and water extracts of Vernonia amygdalina and Secamone africana used by agro-pastoralists in semi-arid land Uganda. The plant materials were collected from…
