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...
ABSTRACT The experiment was conducted at Agricultural Research Institute (ARI)–Ukiriguru Mwanza, Tanzania from November 2011 to May 2012, aiming at improving upland rice performance through enhanced soil fertility and water conservation methods. A split–split plot experiment in randomized complete block design with three replications and three factors that were (a) upland rice cultivars (WAB 450, NERICA1 and NERICA4) (b) fertilizer types, (urea 80kg N/ha, farm yard manure 5 t/ha and contr...
ABSTRACT This study was carried out in Morogoro and Coast Regions. The study used a crosssectional research design where data was collected from a sample of 80 consumers and 30 sellers using structured questionnaire. Also survey methods including personal observations and key informants was used to obtained necessary information. Both qualitative and quantitative data were collected and analyzed using descriptive and inferential statistics and linear regression analysis was adopted by using S...
ABSTRACT Rodents often damage crops throughout the growing season, from germination to harvest, thus making it difficult to understand its cumulative effects for crops such as rice that are able to partially compensate. This study examines response of rice yield to rat damage in farmer’s fields and simulated rat damage in irrigated and rain-fed rice (Oryza sativum L.) in Morogoro, one of Tanzania’s granary areas. The study was conducted at Hembeti village in Mvomero district from Septembe...
ABSTRACT Currently, cooperative enterprises in Ethiopia are growing in terms of numbers and membership. However, despite growing policy attention and researchers‟ interest on cooperatives, the issue of members‟ participation, in relation to performance of cooperatives has not been adequately addressed. The overall objective of this study was to determine the influence members‟ participation in their cooperative financial performance of cooperatives. The study used a cross-sectional rese...
ABSTRACT Field experiments were conducted simultaneously from April to July 2012 at agro-ecologies; Bambi (Latitude 06o09’S, Longitude 039o16’E; and Altitude 20m above sea level) Central District and Kizimbani (Latitude 05o54’S, Longitude 039o16’E; and Altitude 20 m above sea level) Western Unguja district. The aim was to investigate the effectiveness of selected cultural practices (weeding and hilling-up once, twice and thrice), vine portions (apical, middle and basal) and variety (M...
ABSTRACT A field experiment was conducted during 2014/15 growing season at Tumbi, Tabora to study response of sweet potato to organic and inorganic fertilizers. The experiment was split plot laid in a Randomized Complete Block Design with four fertilizer types and different rates; 0, 50, 100, 150 (DAP), 100, 200, 300 kg ha-1 (Minjingu Mazao), 150, 250, 350 kg ha-1 (NPK) and 2.5,5.0,7.5 ton ha-1 (FYM) as main plots and three varieties (Kasinia, Simama and Ukerewe) as subplot in three replicati...
ABSTRACT This study presents the findings on the contribution of women’s income generating activities (IGAs) to the household income in Kigoma Urban District. The overall objective of the study was to assess the extent to which women’s IGAs contributed to household income. The specific objectives were: to identify types of IGAs undertaken by women in the study area, determine contribution of women’s IGAs to the household income, and lastly to determine factors affecting performance of w...
ABSTRACT One of the most important ecosystem services provided by mangrove ecosystems is to act as a carbon sink. Despite this role, most carbon storage studies in Tanzania have concentrated on terrestrial ecosystems. In this study, carbon and volume prediction models were developed for the mangrove ecosystem in Rufiji River Delta, Tanzania. The models developed were used to estimate carbon. Soil organic carbon as an important carbon reservoir was also assessed at different depths. Biomass an...
ABSTRACT Diseases at hatchery stage are among challenges that hinder optimal mariculture development in Tanzania. Information on the occurrences of bacterial infections in mariculture hatchery in the country is limited. Thus, this study was conducted to determine the occurrence and antibacterial sensitivity of bacteria species in Rufiji tilapia and hybrids fingerlings of Nile tilapia female crossbreed with Rufiji tilapia male farmed at different salinity at Institute of Marine Science (IMS) -...
