    Determinants of per capita income growth in Kenya [1965-1995]: an empirical investigation
    (University of Dar es Salaam, 1999) Mutuerandu, Benson Kinoti
    Rapid and sustained per capita income growth in Kenya has been an elusive target to policy makers since independence. The search for the best strategy to ensure sustainable per capita income growth has persistently failed to achieve specific targets as defined in various development plans. This justifies the need for continuous research in this area. Towards this goal, emphasis has been placed on stimulating economic growth and hence per capita income through creation of an enabling environment for private investors, reduction of government role in direct production and development of human capital. Alongside this, has been the emphasis on controlling population growth and achievement of macroeconomic stability. The task of this study is to empirically investigate factors behind the growth of per capita income in Kenya covering the period 1965-95. It is thus a country study unlike most past studies done elsewhere that has been cross sectional in nature. One of the hypotheses that is tested is that investment (private and public) is positively related to per capita income growth. The hypotheses of this study have been investigated using OLS estimation technique and test of co integration. The regression results reveals that trade policy, macroeconomic policies, population and structural policies have some impact on per capita income growth in Kenya. Despite limitations of the coverage and poor quality data, the findings of this study set a good direction on policies pertaining to per capita income growth that should be put in place to raise standards of living in Kenya. The findings of this study will thus be useful guidelines to policy makers when deciding on measures to be put in place in order to achieve high and growing per capita income in Kenya. The findings will also widen the frontier of knowledge on per capita income growth. Further research is, however, encouraged in order to get a good policy mix of enhancing per capita income growth in Kenya

    Evaluation of the performance of tomato (solanumlycopersium l.) lines/cultivars resistant to salinity
    (University of Dar es Salaam, 2011) Nnungu, Hamis Issa
    Low yields of tomato (Solanium Lycopersicum) along the coast of Tanzania are influenced by abiotic stresses such as salinity. Commercially available cultivars have been developed to address the aspects of biotic stress as most tomatoes are grown in highland areas in moist and low saline soils. Efforts to test cultivars being developed for production in marginal areas were made. Test lines from the World Vegetable Research Center Arusha Regional office were evaluated for salt tolerance, presence of stress proteins and market acceptance of tomato fruits. The effects of salinity (45mM, 90mM and 150mM NaCI) on the growth of selected tomato lines and variation to such effects were studied. Increasing salinity delayed and reduced seed germination at varied among lines. ARP-365-2-5. ARP 367-1. CLN 1621, CLN 2001A, CLN 2413R, CLN 2418A, CLN 5915-93-1-0-3 and BL 1173-76 were found to germinate at all salinity levels in this study though germination was delayed. Seedling growth in terms of height increased with time but decreased with salinity except in the CLN series where only slight decreases in height were observed. Vegetative growth was negatively affected in Tanya and Tengeru cultivars by high salinity levels. The CLN series were found to yield reasonably at all salinity levels in particular CLN 5915-93-D4-1-0-3 although the fruits were very small in size. CLN 5915-93-D4-1-0-3 tomato fruits were less favoured by consumers due to their small size whereas BL 1175 were more favoured due to the medium size, best flavour and taste, firmness and longer shelf life. The expected presence of dehydrin protein as reported by other studies was not observed hower this does not conclusively imply that there are no dehydrins in all tomato lines.
