ABSTRACT Generally in Tanzania consumers prefer local chickens and pay premium prices compared to other chickens due to the perception that local chicken tastes better, nutritious and organically raised. However, productivity levels of local chicken are low resulting to low outputs hence limiting their potential for commercialization. For that reason, the African Chicken Genetic Gain program has recently introduced tropically adapted improved chicken including Sasso, Kuroiler and Black austr...
ABSTRACT Common bean anthracnose disease caused by the fungus Colletotrichum lindemuthianum causes significant yield losses. It is most destructive in areas with cool temperatures and high humidity (90 - 100 %). The aim of the study was to introgress resistance gene into adapted but susceptible local cultivars Masai Red and Soya Njano using conventional breeding methods. Five races of C. lindemuthianum were isolated and named, from thirty two common bean diseased plants samples collected fro...
ABSTRACT An experiment was conducted to determine the effectiveness of potassium in mitigating drought stress and improving yield in lowland rice ecosystems at Sokoine University of Agriculture Morogoro Tanzania. The main plot constituted three soil moisture levels viz. flooding, 20 and 40 kPa soil moisture tensions. Subplot factor constituted three lowland rice varieties viz. SARO, NERICA4 and SUPA while potassium levels were 0,50 and 100 kg K ha-1 for field experiment and 0, 25 and 50 mg K...
ABSTRACT Restoration of degraded natural areas to enhance genera conservation is widely gaining pace; however, effort geared at assessing response of animal community particularly in restored forests is still low. I used a CMR method to trap rodents and measured vegetation characteristics to examine the association of vegetation characteristics with rodent abundance, diversity and occupancy in a secondary forest 20 years after restoration. the results found first, five rodent genera were in ...
ABSTRACT The objective of this study was to examine the level of technical efficiency of smallholder pearl millet producers and identify its determinants in the semi-arid farming system of Dodoma, Tanzania. A Translog stochastic production function model was used in the analysis. To specify technical inefficiency effects of socioeconomic variables, Maximum Likelihood Estimation (MLE) technique using cross sectional data collected from 300 randomly selected sample farmers in 2016 was applied....
ABSTRACT Savannah grasslands are occupied by large mammal herbivores whose ecological separation between and within each guild have resulted to different foraging strategies and preference for forage differing in attributes to reduce competition between them. Therefore, the current study aimed at: 1) measuring the relative use of burnt and non-burnt areas by waterbuck, wildebeest and reedbuck, and their possible shifts between the two patches over time; 2) assessing forage characteristics in...
Abstract A 49-day feeding trial was carried out with feeds supplemented with microgram quantities of the defatted seeds of Artocarpus heterophyllus in the diets of Clarias gariepinus at the post juveinile stage. Five diets at 40% crude protein were formulated containing 0, 15, 30, 45 and 60x106 µg DAH seed as additive. Each dietary treatment was replicated three times with 10 fish per replicate. Proximate composition of the defatted seed showed that it was rich in protein, carbohydrate ...
ABSTRACT This study analyzed Irish potato value chains so as to identify potential areas for interventions towards improving income for the various actors involved in the chain in Njombe Urban and Wanging’ombe districts. Data were collected from 202 Irish potato value chains actors using individual interview and focused group discussions (FGD). Sub sector mapping, gross margin analysis and regression analysis were used in the study. Subsector mapping analysis was used to map Irish potato v...
ABSTRACT A study was carried out to assess the profitability of improved banana cultivars in Rungwe, Mvomero and Mkuranga districts. Specifically, the study aimed at comparing benefits of improved versus non improved banana cultivars production, determining the contribution of banana enterprise to total household income, assessing the factors that influence banana household income, assessing the changes in gender roles in improved banana farming system and suggesting the system of distributi...
ABSTRACT Although, agriculture remains the main source of income and employment in developing countries, it is a universally accepted fact that agricultural sector is incapable of creating sufficient income in the middle of increasing population. Thus, the non-farm sector is increasingly becoming important. Generally, the study assessed the effects of non-farm activities to household income in purposefully selected rapidly urbanizing villages in Mufindi District, namely; Nyololo Shuleni, Lug...
ABSTRACT High tunnel technology has been heralded as the panacea to propel medium and small scale tomato production due to high levels of efficiency and the potential to support sustainable socio-economic development in the face of current daunting challenges and opportunities to which farmers respond. However, despite the comparative advantages offered by the technology, its adoption by farmers has been far less than satisfactory. A study was therefore carried out to investigate constraints...
ABSTRACT The study was carried out to determine the economic performance of beekeeping enterprises and their contribution to livelihood focused on level of income that a household earn from beekeeping in Songea district of Ruvuma region in Tanzania. Specifically the study was sought to (i)Determine the income generated from beekeeping enterprises in the study area, (ii) Determine the viability of a beekeeping enterprise in the study area, (iii) Determine the contribution of beekeeping on the...
ABSTRACT Consumers’ preferences for food products are always based on observable and nonobservable attributes. Common beans which are globally important for income generation as well as food and nutrition security, appeal to consumers in different ways. One important distinction of this nature is with respect to colour, size, cooking time and gravy quality. When multiple common beans’ varieties with varying attribute levels are exposed, consumers normally select multiple varieties on the...
ABSTRACT Improving free range local chicken (FRLC) production through vaccinating against Newcastle disease (ND) at the village level is an important component in improving socio-economies of the rural communities in Tanzania. This study assessed the socioeconomic impact of FRLC vaccinated against ND in rural communities of Mvomero District. The Primary data were gathered from a sample of 181 respondents from Sangasanga, Changarawe, Tangeni, Kimambila, Lubungo, Mafuru and Vikenge. The primar...
ABSTRACT The production of milk from cows in Tanzania has not reached the optimum levels due to several constraints including poor genetic potential of animals, lack of feeds especially good quantity and good quality during the dry seasons, prevalence of diseaseases, generally poor management and lack of good husbandry practices. Mastitis is one of the important disease that lowers the milk production and quality in local and dairy cattle in Tanzania. This cross sectional study was conducted...
