ABSTRACT Despite government and other stakeholders efforts to promote improved cassava varieties (ICV) to farmers in MagharibiDistrict in Zanzibar, cassava yield is yet below the Tanzania’s average of 8 t/ha and the average yield of 14 t/ha of Africa. Cassava Brown Streak Virus (CBSV) and Cassava Mosaic Virus (CMV) are the main causes of the yield losses; hence ICV were developed to address this issue, however, yet adoption of the ICVis poor. Farmers are still using local cassava varieties ...
ABSTRACT This study assessed the effects of human activities on woody plant species composition of Ngarama South Forest Reserve (NSFR) in Kilwa District, Tanzania. Vegetation survey was carried out in 40 systematically established rectangular sample plots aligned in five transects across the entire forest of 2 070 ha. The information recorded in each plot included: species name, diameter at breast height (DBH), height of few selected woody species with diameter ≥ 5 cm and various indicators...
ABSTRACT Consumption of Indigenous vegetables (IVs) in most Sub-Sahara African countries including Tanzania is replaced by exotic varieties/species, regardless of their potential nutritional and economic values. Given this situation, among other IVs, this study was conducted with the aim of assessing consumers‟ acceptance and willingness to pay (WTP) for processed cassava leaves products. Sensory test together with a consumer survey of 110 randomly selected respondents was conducted in Moro...

Interview with key informants and focus group discussions (FGDs) were also conducted. The analysis of collected data was done using the Statistical Package for Social Sciences (SPSS). This stud...
ABSTRACT Miombo woodlands are major vegetation type covering about 93% of the forest land of Mainland Tanzania. It forms an integral part of the rural landscape in Tanzania and plays a crucial role in providing a wide range of goods and services including carbon sequestration. However, the sustainability of miombo woodlands resources depend on the balance between increment/growth rate and the magnitude of utilization. While many studies have been conducted to evaluate growth rate/increment li...
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...
