    Distribution and regeneration status of Vitex payos (Lour.) Merr. in Kenyan drylands
    (Journal of Horticulture and Forestry, 2014) Kimondo, James M.; Agea, Jacob G.; Okia, Clement A.; Dino, Andrew W.; Ahmed Abohassan, Refaat A.; Mulatya, Jackson; Teklehaimanot, Zewge
    We investigated the population structure and regeneration status of Vitex payos (Lour.) Merr. in Kenyan drylands. The study quantified the spatial distribution pattern of V. payos tree populations in their natural range; and assessed their regeneration status to determine the stability of the populationsWoodlands and farm inventories were conducted in Mbeere, Mwingi and Kitui districts of the Eastern Province of Kenya. The nearest-neighbour sampling method was used to determine tree density and distribution of V. payos in the study sites. The number of seedlings and saplings were counted. The diameters, crown diameter, and tree heights of sampled trees were measured. These morphological parameters were summarized on per hectare basis. The patterns of distribution of V. payos trees showed an aggregation of trees on farms and bushes. Tree densities ranged from 1.6 on farmlands to 20.3 trees per ha in the woodlands. The expected mean distances between nearest neighbouring trees were higher than the observed values on all sites, confirming that V. payos trees were more aggregated than randomly dispersed. The mean tree heights varied from < 5 m to > 9 m cross study sites. The sampled populations were dominated by trees (55%) within the range of 10 to 20 cm dbh. Highhest numbers of seedlings from all origins were recorded in the bushes in Kitui and Mbeere districts 101 and 78 seedlings per hectare, respectively. Sapling population densities were generally low.

    Impediments, opportunities and strategies to enhance trade of wild and semi-wild food plants in Bunyoro- Kitara Kingdom, Uganda
    (International Journal of Medicinal and Aromatic Plants, 2011) Agea, Jacob G.; Obaa, Bernard B.; Kimondo, James M.; Okia, Clement A.; Isubikalu, Prossy; Woiso, Dino A.; Obua, Joseph; Teklehaimanot, Zewge
    This study examined the impediments, opportunities and strategies to enhance trade of wild and semiwild food plants (WSWFPs) in Bunyoro-Kitara Kingdom, Uganda. Semi-structured questionnaire was administered face-to-face to sixty six (66) traders of WSWFPs in the formal markets: five (5) mobile hawkers and eleven (11) home-based/roadside traders. As a result of their small number, all traders that were found selling WSWFPs were interviewed. Data were analysed using simple descriptive statistics in excel spreadsheet and MINITAB statistical package. A number of challenges including high perishability, market dues, inaccurate consumers’ perceptions, seasonal shortfalls and unreliable supply, unorganized markets, little or no value addition, limited market information, and the inexistence of market promotional activities affected the trade in WSWFPs. However, the growing market demands, increasing focus of most service providers in creating awareness on WSWFPs, ever-changing perception on nutritional values of WSWFPs by the public, current government emphasis on value addition of traded agricultural products, little or no capital requirement for starting up trade in WSWFPs, and absence of restrictive regulations on sale of WSWFPs were regarded as good opportunities that could be exploited to enhance trade in WSWFPs. Key strategies for improved marketing WSWFPs included among other things, training gatherers and traders on value adding activities prior to sale, deliberate investment in promotional and awareness campaigns to expose the hidden benefits of WSWFPs, scrapping market dues levied on traders selling WSWFPs, helping gatherers and sellers to organise themselves to form viable supply and market groups, linking gatherers and sellers to good markets, as well as providing them with available market information. There is thus, a need for concerted efforts to implement some of these feasible marketing strategies to improve on the markets of WSWFPs in the kingdom.

    Physiochemical and nutritional characterization of Vitex payos (Lour.) Merr. (Verbenaceae): An indigenous fruit tree of Eastern Africa
    (Journal of Horticulture and Forestry, 2012) Kimondo, James M.; Agea, Jacob G.; Okia, Clement A.; Abohassan, Refaat A. A.; Nghitoolwa Ndeunyema, Elizabeth T. N.; Woiso, Dino A.; Teklehaimanot, Zewge; Mulatya, Jackson
    In the dry areas, indigenous fruits become important staples when cereals harvested are inadequate to support populations. Farmers in these areas have identified many of the handicaps in domestication but there is still need for inputs from the food industry into identification of the desirable traits and characteristics of potentially novel food. The purpose of this study was to assess the nutrient content of one edible wild fruit, Vitex payos that has been identified as a top priority species among the inhabitants of drylands of Kenya for domestication. The proximate, minerals and vitamin content were determined. Results showed that the fruit did contain useful quantities of potassium, manganese, phosphorus and vitamin C. Besides, sodium, magnesium and calcium were also present in minute quantities.
