ABSTRACT The recent intensified aquaculture projects in Lake Kariba have brought about disease outbreaks in cultured Oreochromis niloticus. This has brought on an awakening to the scientific knowledge gap surrounding these events. This study aimed at identifying bacteria associated with diseased O.niloticus and establishes theirantibacterial resistance patterns. The diseased fish in cages were identified based on behavioural and physical abnormalities including swimming in circles, swimming i...
ABSTRACT The study was conducted to examine the factors for sustainability of water projects in IringaDistrict, Tanzania. Iringa District was selected as the area of study because in spite of many water projects invested at the area, the accessibility of clean water is only 40.7%. The study specifically ought to determine water sources protection strategies adopted at the study area, to assess participation of stakeholders in different stages of water projects development, to analyze the inst...
ABSTRACT Common bean is a major source of food and income for smallholder farmers in Tanzania.The national average yield for common beans which ranges from 0.72 to 1.10 tone/ha, is far below potential yields recommended by agricultural research (1.5 – 3 tones/ ha) using improved varieties. Low common bean yield is contributed by several factors which lower farmers` profit. This study examined the economics of smallholder common beans production in Mbeya, Tanzania. Descriptive and inferentia...
ABSTRACT The experiments were conducted at Zimbabwe Sugar Association Experiment Station, Chiredzi, Zimbabwe during the period 2015-2016 to study the growth, yield and economic benefit analysis of sugarcane as influenced by plant media, intra-row spacing and varieties. Two experiments were conducted with the 1st experiment that evaluated the best plant media to raise sugarcane bud chips and the 2nd experiment on determining the best intra-row spacing that gives best yield, using different sug...
ABSTRACT Lack of simple storage facilities in tomato supply chain contributes to high postharvest losses of tomato in Tanzania. In the field, harvested tomatoes are left in an open area and occasionally covered with grasses or sometimes under shade trees. Refrigerated storage structures are relatively expensive to build and operate; and most people living in rural areas cannot afford. This study was conducted to determine the effect of on farm storage technology (zero energy cool chamber) wit...
ABSTRACT This study aimed at undertaking a comparative analysis of farm power technologies; manual, oxen, 2WT and 4WT in Rice Production for Smallholder Farmers in Mbarali District, Tanzania. The study had three objectives namely: (i) identification of different farm operations by power sources used by smallholder farmers in paddy production, (ii) analysing costs and returns per unit area of using the mentioned sources of farm power and (iii) examining factors influencing smallholder farmers�...
ABSTRACT The study was conducted to assess students’ academic performance under Secondary Education Development Plan (SEDP I) implementation in Nyamagana District, Tanzania. Data were collected using both structured and non-structured interviews. Field observations and secondary data supplemented the data collected using questionnaires. Purposive sampling procedure was used to select 5 schools that were in place before and after SEDP 1 implementation. At the school level, 12 teachers and 8 ...
ABSTRACT This study was conducted to analyze cassava and sweet potato value chains so as to identify potential areas for intervention in order to improve small-scale farmers’ access to markets in Mvomero and Kongwa Districts. Sub-sector mapping was used to map cassava and sweet potato value chains. Results indicate that several constraints exist in the two sub-sectors which among other things include low production, poor access to inputs, lack of market information, poor support services, p...
ABSTRACT This study assessed the effects of institutional changes on forest condition, stakeholders’ interests, the performance of local institutions and factors influencing the performance of local governance structures, using a case study of Chenene Forest Reserve (CFR) in Bahi, Tanzania. Data were collected through forest inventory using 120 systematically selected sample plots. Satellite images were collected and analysed using Remote Sensing and Geographical Information System techniqu...
ABSTRACT Sweet sorghum (Sorghum bicolor L.) has been recognised widely as a potential alternative source of biofuel because of its high fermentable sugar content in the stalk. With international focus on alternative fuel sources, investors are looking at sweet sorghum as a feedstock source for bioethanol production without compromising sorghum’s primary use for food, fodder, and animal feed. However, for researchers to maximize its feedstock potential and to be used in future there is a nee...
ABSTRACT Household food security is an important development issue. However, food insecurity still persists in many parts of Tanzania due to a number of factors. When people are faced with food shortage, they develop mechanisms to cope with this problem. These strategies, however, are neither effective nor sustainable. Therefore, this study was conducted to assess the effectiveness and sustainability of coping strategies towards food insecurity in Chamwino area in order to suggest possible wa...
ABSTRACT Farmer training is essentially an agricultural extension education with a non-formal function, which applies to any institution that disseminates information and advice with the intention of promoting knowledge, attitudes, skills, and aspirations. When systematically and effectively provided, extension is known to enhance social and economic development. In terms of agricultural extension systems, different approaches can be employed to organize and implement extension activities. Ea...
ABSTRACT This research was carried out in the inshore of Lake Victoria, Rorya District in particular, to examine determinants of gendered adaptive capacity to climate change and its role in enhancing food security among artisanal fisher folk. The specific objectives were: to examine fishers perception on climate change by gender; to determine the adaptive capacity of artisanal fishers by gender; and to determine factors affecting the adaptive capacity to climate change by gender. A total of 9...
ABSTRACT Cashew (Anacardium occidentale L.) is an important export crop in a number of tropical countries and is the main cash crop and the leading source of income for over 300,000 households in Southern and Eastern Tanzania. Farmers still, however use unimproved varieties, which account for low yields. Thirty cashew genotypes were evaluated to assess genetic variability for higher yield and its components at two locations (Nachingwea and Chambezi) in the Southern and Eastern zones of Tanzan...
ABSTRACT Cassava (Manihot esculenta Crantz) is one of the important crops in the world for food and income security. Cassava production is challenged by weeds as they reduce yield to 100%. Effective weed management in cassava production depend determination of weed species diversity and determination of Critical Period for Weed Removal (CPWR). A study was conducted in Zambia, to document weed species diversity in cassava growing areas of Chongwe and Kaoma districts in Zambia, determine the cr...
