    Abstract This paper is about the result of a survey done in the 2014-2015 cropping season of field day participants and agro-vets who were facilitated to market SSPs and SFPs in Singida and Iramba districts of Tanzania. The objective of the survey was to determine whether there was any correlation between awareness creation and preferences reported during field days and the demand for technological inputs from the agro-vets. The results showed a strong complementarity between the dissemination of information on improved technologies during field days and the retailing of SSPs and SFPs in agro-vets. The field days help in creating awareness about the benefits and attributes of available improved sorghum and finger millet varieties and associated agronomic recommendations; while retailing of the SSPs and SFPs by the agro-vets not only helps promote the demand for improved technological inputs but also enhances their accessibility as SSPs and SFPs are more affordable to resource poor farmers. Therefore, having field days for awareness creation without improving accessibility of technological inputs through sale of SSPs and SFPs or vice versa is futile and does not lead to enhanced experimentation and adoption of improved technologies by target farmers.

    Abstract Participatory variety selection (PVS) is an approach which provides a wide choice of varieties to farmers to evaluate in their own environment using their own resources for increasing production. It enhances farmer’s access to diverse crop varieties, increases production and ensures food security and helps faster dissemination and adoption of pre and released varieties. It allows varietal selection in targeted areas at cost-effective and timely manner and helps promotion of community seed production and community seed banks. Therefore, a variety developed through PVS usually meets demand of different stakeholders. Farmers in Singida and Iramba districts in central Tanzania were found to be growing land races which were low yielding, long maturing, drought and disease susceptible, as no variety had previously been released in Tanzania. Through PVS a broader choice of varieties that matched farmer needs in adaptation and quality traits was offered for evaluation. As such PVS was used to introduce, evaluate, release and promote for adoption finger millet varieties in Central and Northern Tanzania. Farmers selected and adopted new varieties of a higher utility (a combination of improved agronomic traits, higher yield, and improved quality). Through PVS Tanzania released her first finger millet varieties (U15 and P224). Adoption of the varieties was very high as farmers associated with the varieties; and affordable high quality seed was made available as Quality Declared Seed (QDS) produced by the target farmer groups. Preferred traits differed between the gender groups; women preferred risk averting traits like short duration, drought tolerance, compact heads and disease resistance while male preferred market related traits (high yield, brown colour and big head.

    Abstract A survey was conducted in 2014 to determine the prevalence of fungal diseases on sorghum across different agroecological zones in Tanzania and Uganda. In Tanzania, 37 sorghum fields were sampled in Dodoma and Singida Provinces, representing the central drier areas, and in Simiyu, Shinyanga, Mwanza, and Mara Provinces, representing the lake-zone region. In Uganda, 134 fields were sampled across four agroecological zones of Teso, Western, Northern, and West Nile. Farmers were purposively selected, and at least 30 plants per field along two diagonal transects were visually assessed for disease. Ten and 14 diseases were identified in Tanzania and Uganda, respectively. Among the major diseases identified, those more prevalent in Tanzania than in Uganda were leaf blight caused by Setosphaeria turcica (P = 0.0031) and rust caused by Puccinia purpurea (P < 0.0001). Major diseases more prevalent in Uganda than in Tanzania were anthracnose caused by Colletotrichum sublineola (P = 0.0207) and zonate leaf spot caused by Gloeocercospora sorghi (P = 0.0312). We report for the first time the occurrence of ladder leaf spot caused by Cercospora fusimaculans in Uganda and confirm its occurrence in Tanzania. This is the first comprehensive sorghum disease survey report in over 15 years in both countries.

    Abstract This study was camed out to select an improved pearl millet variety acceptable to the farming community of Tanzania, after comparison with farmers' local kandrace varieties [LLVs). Twenty-one farmers from three districts participated. Improved varieties TSPM 91 01 8 and TSPM 91 001, which had been used in national on-station trials for more than three seasons and were found to be promising, were established in the farmers' fields in three districts in the 1993/94 season. The farmers' LLV and Serere 17, an improved released variety, were included in the Singida district trial for additional comparison.
