Performance of sweet potato varieties across environments in Kenya
(2012-09)
Sweetpotato is an important food, feed and cash crop in Eastern Africa but its adoption as a dual purpose crop has not been exploited. Varieties giving high tuber and vine yields would be ideal for small scale farmers who ...
Effect of Reduced Tillage and Mineral Fertilizer Application on Maize and Soybean Productivity
(2012)
Reduced tillage is said to be one of the potential ways to reverse land degradation and ultimately increase the productivity of degrading soils of Africa. We hypothesised that crop yield following a modest application of ...
Characterization of Uromyces appendiculatus isolates collected from snap bean growing areas in Kenya
(Academic Journals, 2012-11-02)
Bean rust (Uromyces appendiculatus (Pers.:Pers.) Unger var. appendiculatus) is one of the most devastating and variable pathogens of common bean (Phaseolus vulgaris L.) worldwide that can cause total crop loss. Characterization ...
New sources of resistance to spotted stem borer, Chilo partellus in sorghum
(2012)
The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% ...
Novel source of sorghum tolerance to the African stem borer, Busseola fusca
(Academic Journals, 2012-08)
Sorghum (Sorghum bicolor) is an important cereal food crop in semi-arid tropics, but its productivity is curtailed mainly by insect pests and diseases. The African stem borer, Busseola fusca Fuller (Lepidopteran: Noctuidae), ...

Partial Nucleotide Sequences of Sweet Potato Leaf Curl Virus Occurring in Kenya and its Phylogenetic Relationship with other Members of Begomoviruses
(2012-11)
Sweet potato leaf curl virus has been reported in different sweet potato growing regions of Kenya. Partial nucleotide sequences of Kenyan Sweet potato leaf curl virus isolates were compared with other isolates from different ...
Yield Selection within Coffea arabica cv. Ruiru 11
(SCIENCEDOMAIN international, 2012-08-17)
Aims: This study was aimed at identifying high yielding Ruiru 11 sibs in varying growing
conditions. The study also intended to measure the extent to which cherry yields of Ruiru
11 are affected by the environment. Study ...
Selection of Ruiru 11 hybrid sibs on raw coffee quality
(2012-06)
The economic value of Arabica coffee (Coffea arabica L.) is determined mainly by the yield potential, the size and shape of raw beans and beverage quality. Bean quality reportedly differ depending on the variety, environmental ...
Comparison of a gas fired hot-air dryer with an electrically heated hot-air dryer in terms of drying process, energy consumption and quality of dried onion slices
(Academic Journals, 2012-08-14)
Onion slices were dried in either a gas-fired hot air dryer or an electrically heated hot air dryer at air temperatures of 50, 60 or 70°C, and at air flow velocities of 0.5, 1.0 or 2.0 m/s. Records of the drying rates and ...
