Evaluation of growth of gliricidia sepium provenances at Gairo, Kibaha and SUA farm, Tanzania
(Sokoine University of Agriculture, 2003) Gerald, Vincent Vyamana Kavura
Growth evaluation was conducted among seventeen provenances of Gliricidia sepium at Gairo, Sokoine University of Agriculture (SUA) farm and Kibaha, Tanzania. Assessment was done at irregular intervals for survival, root collar diameter and diameter at 30 cm above the ground, height, multiple stems production. foliage and wood and total biomass production. Final assessment of these tree attributes was done at 70, 69 and 34 months after planting for Gairo, SUA farm and Kibaha site respectively while unit leaf mass, foliar N and P concentrations was assessed at 73, 72 and 36 months after planting for Gairo. SUA farm and Kibaha site correspondingly. For SUA farm site, during the final assessment occasion, height ranged from 3.77 (Taxico) to 4.85 m (Belen Rivas), foliar N concentration ranged from 3.58 (Taxico) to 4.24% (Thailand) while P concentration ranged 0.16 (Playa Tamarindo) to 0.19% (Gualan). Multiple stems production ranged from 15000 (Cuyatenango) to 28750 stems ha'1 (sph) (Thailand) while biomass yields were 17.34 (Retalhuleu) to 27.73 t ha'1 (Belen Rivas), 72.99 (Retalhuleu) to 118.54 t ha'1 (Belen Rivas) for foliar and wood biomass respectively. For Gairo site, height ranged from 3.87 (Monterrico) to 4.39 m (Cuyatenango), foliar N concentration ranged from 3.68 (Kihonda) to 4.38% (Cuyatenango) while P concentration ranged 0.26 (Kihonda and Taxico) to 0.30% (Balen Rivas). Multiple stems production ranged from 27500 (Cuyatenango and Monterrico) to 33438 sph (Retalhuleu) while biomass yields were 13.72 (Monterrico) to 18.68 t ha'1 (Cuyatenango) and 60.76 (Monterrico) to 95.15 t ha'1 (Cuyatenango) for foliar and wood biomass respectively. For Kibaha site, heightiii ranged from 4.45 (Nigeria) to 5.26 m (Jutiapa), foliar N concentration ranged from 3.69 (Ibadan) to 3.93% (Jutiapa) while P concentration ranged from 0.20 (Ibadan) to 0.24% (Taxico). Multiple stems production ranged between 16563 (Jutiapa) to 22031 sph (Nigeria) while biomass yields were 15.45 (Nigeria) to 20.19 t ha'1 (Cuyatenango), 37.26 (Nigeria) to 49.15 t ha'1 (Cuyatenango) for foliar and wood biomass respectively. Based on the findings, provenances Balen Rivas. Cuyatenango and Juliapa arc recommended for SUA farm: Cuyatenango and Taxico for Gairo: and Cuyatenango and Jutiapa for Kibaha. Further evaluation of these and other provenances on resistance to pests and disease, nitrogen fixation and coppicing ability for various conditions in Tanzania are recommended. In addition, more studies to compare performance of other G. sepiuni provenances in more contrasting sites should be undertaken.

An analysis of market information services efficacy in maize production and marketing sub-sector: the case of Kongwa district, Dodoma region.
(Sokoine University of Agriculture, 2007) Kisenge, Kajiru
The study assessed the relevance of the current agricultural market information available to farmers for purpose of increasing their efficiency and effectiveness in agricultural commodity market exchange, and establishes farmers’ willingness and ability to access better information from a mix of alternative sources. Specifically the study objectives were: (i) to asses the type of market information needed by farmers (ii) to identify sources of information used by farmers, (iii) to asses the type and frequency of delivering the preferred market information, (iv) to establish farmer’s willingness to pay for market information. A simple random sampling technique was employed to select 280 farmers. Qualitative analyses performed included computation of frequencies and cross tabulation. Quantitative analyses involved logistic regression. The study found that, 90.4% of households have access to information on where to sell and market selling prices than other types of information such as weather, credit, sources of inputs, and sources of agricultural equipment's. Friends and neighbors, radio, local financial institutions were found to be the most important sources of information for farmers. Despite the fact that farmers have full knowledge of prices, the majority of farmers 91.5%, sell their maize immediately after harvestings when prices are lowest. Regression results show that education of the respondent and farm size owned by the respondents had significant and positive influence on Willingness-to-Pay (p< 0.01) for information. While age and amount of money the farmer is willing to pay has a negative sign and insignificant in its relationship with Willingness-to-Pay for market information. Based on the study findings, it is recommended that market information access will be improved by localization of market information, improving means of delivering market information, promoting market information needs and improving institutional and organizational arrangements.

Uptake of index-based crop insurance among smallholder farmers: the case of rice producers in Mvomero- Morogoro
(Institute of Finance Management, 2022) Mpunde, Venance Michael
In spite of agriculture being source of livelihood in Tanzania, yet the sector is faced by various production risks including climate change and variability. Since crop insurance is an important strategy against natural hazards and risks, farmers arc encouraged to adopt it in order to intensify farm productivity. Therefore, this study sought to determine drivers for uptake of index based crop insurance and inform ways of making crop insurance work for the smallholder producers. Data were collected using questionnaire from 102 rice-producing households where weather index-based insurance had been promoted. A total of 5 insurance companies were also selected for KIIs to determine their distribution models and challenges they face in implementing IBCI. BLRM was used to assess the drivers to adopt IBCI, Content and descriptive analyses measured distribution models and challenges insurers face to implement IBCI respectively. The results show that age of the household(p=0.098), farming experience with IBCI (0.000), distance to the paved road (p=0.014), and household income (0.010) had significant influence to farmers’ participation in IBCI. The content analysis from insurance companies showed that selling covers through local agents was dominant method they use in reaching their clients, quality and availability of weather data (37.5%) and capacity building to stakeholders (29.17%) were serious challenges to implement the programme. These findings therefore highlight the need to create more awareness to farmers on the principles of crop insurance and different products that exist. Similarly, developing good channels that will adequately suit the farmers needs and designing of crop insurance products basing on the need of clients, by doing so the uptake of crop insurance in Tanzania will increase.

Farmers’ choices for sustainable intensification technologies in Kilosa district, Tanzania
(Sokoine University of Agriculture, 2017) Mugula, Joseph Jovin
The aim of this study was to assess farmers' choices to the adoption of sustainable agriculture practices (SAPs). It specifically aimed at determining the level of adoption profit margin between SAPs adopters and non-adopters and the influence of socio- economic and institution factors to the adoption of sustainable agriculture practices. A cross-sectional research design was used involving 550 smallholders maize fanners. The secondary data collected was used to undertake and enrich the study. Descriptive statistics was used to examine the adoption rale of SAPs among smallholders' farmers in Kilosa District. Binary logistic regression analysis was used to analyze the socio- economic and institutional factors affecting the decision of a farmer to adopt SAPs. Findings indicated that there was a low rate of sustainable agriculture practices adoption (27%) among smallholders farmers in Kilosa district despite the available policies to encourage the use of SAPs. Moreover, profit margin indicated that there was a significant difference between the adopters and non-adopters of SAPs with respect to maize production regarding the mean yield and revenue obtained from the field Education, level of income of farmers, farm size, family size, and extension service were socio-economic and institutional factors that significantly (p<0.05) affected farmers' choice to adopt SAPs. Generally, findings from the study suggested that policy makers at Kilosa District should address the factors that significantly influence the adoption of SAPs and to encourage the delivery of extension services by private agents. This might increase the adoption rate of SAPs among reluctant smallholder farmers for the consistent dissemination of S/\Ps as a way forward towards the sustainable improvement of food security and livelihoods of agriculture stakeholders.

Compliance with the international code and national regulations of marketing of breast-milk substitutes and designated products in Tanzania
(Sokoine University of Agriculture, 2010) Obadiah Ndeng’anyiso Msaki
A study to estimate prevalence of non-compliance with the WHO International Code and Tanzania National Regulations (NRs) for Marketing of Breast-milk Substitutes and Designated Products was conducted in seven selected health care facilities and 10 infant food retail outlets in Dar es Salaam and Morogoro urban centres. A multi-site cross- sectional questionnaire-based survey/interview was used. The study showed that both the NRs and the Code were violated in all health care facilities and retail outlets. Majority of health workers (87.8%) were not aware of the existence of the Code. Only 12.2% health workers across surveyed districts were aware of the NRs. Across the districts the health care service was the most common source (64%) of free or subsidized samples of Breast- milk Substitutes (BMS) received by pregnant women and mothers, in contravention of Article 7.4 of the Code. About three quarters (72.2%) of pregnant women and 61.1% mothers had not been counselled about infant feeding. It was found that 35 BMS and designated products violated one or more of the provisions of the Code and NRs. Over half (57.1%) of the products that violated the Code recommended inappropriate ages of introduction; 45.7% had no labelling information that the product should be used only on advice of health worker; 54.3% had no warning against health hazards of inappropriate use; 91.4% carried pictures, drawings, or text idealizing use of the product. The Government has an obligation to ensure that legislation is accompanied by effective awareness-raising, training, information, implementation and monitoring systems to guide practices of health professionals. Control of infant foods trade in the East African Community and Southern Africa Development Community needs to be harmonized and coordinated to enhance effective implementation of the Code and the NRs and subsequent improvement in infant and young child feeding practices in East Africa and Tanzania.
