    Policy brief
    Improving access to quality seed potatoes 2017
    Also available in:

    This policy brief addresses the issue of limited farmer access to quality seed of Irish potato varieties in demand in local markets, which is a severe constraint for the potato sector in eastern Africa. It provides evidence in support of urgently needed action and presents options for practical decisions by policy-makers in the subregion.

    Development and supply of superior germplasm is important for the promotion of tree planting. Kenya has lost many tree seed sources through deforestation, land degradation, forests encroachment and conversion of agricultural land to housing. Nevertheless, limited access to tree seeds of high quality is the major constraint to sustainable tree production in Kenya and proper information on storability of extracted seeds is lacking. Melia volkensii trees species is highly valued in drylands of Kenya for tremendous roles in social-economic, ecological and environmental protection, and conservation. This experiment aims at determining viability test of Melia seeds stored as nut over period of one year and the resultant effect that they will have on seed germination. Furthermore, the research investigates the conducive environment that would favor storage of Melia seeds in order to improve its viability status. The experiment showed that Melia seeds stored at room temperature and a temperature of 4 degrees centigrade had higher germination capacities compared to Melia seeds stored at a temperature of -20 degrees centigrade. The peak average germination speed was 2.11 with a germination value of 3.99. Significant (p value ≤ 0.001) differences were observed in the germination capacities between Melia stored as seeds and nuts for the first, second, third, fourth, fifth, sixth and seventh germinations (p value ≤ 0.05). From the study, Melia stored as seeds at a temperature of 4 degrees centigrade had the highest marginal germination capacity. This study provides the best information for storage and handling of Melia seeds in maintaining its viability.
