Soil properties along a gradient from hillslopes to the savanna plains in the Lambwe Valley, Kenya
(Elsevier, 2015-12-01)
Changes in land use and management strongly affect the physical and chemical properties of soils and their ecological functions. Especially, regions in East Africa have experienced dramatic land use changes in the past, ...
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Netherlands, 2015-10-01)
Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ...
Research in the quality of service delivery in public hospitals, Kenya
(Journal of Pharmacy and Biological sciences, 2015)
The study reported in this paper purposed to establish the quality of service delivery in public hospitals in Kenya. The study assessed the quality of service delivery to malaria patients in wards for malaria patients in ...
Identification of QTL for Striga hermonthica Resistance Using Backcross Population Derived from a Cross between Oryza sativa (cv. Nipponbare) and O. rufipogon
(Canadian Center of Science and Education, 2015-02-01)
The obligate root hemiparasite, Striga hermonthica (Del.) Benth., native to sub-Saharan Africa causes serious
economic constraint to cereal production. Studies on Striga spp. interactions with rice are desirable as it is ...
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Allelopathy is a common among plants. Allelopathic substances affect seed
germination, plant growth and development or even affect chlorophyll
synthesis by the plant leaves. Tithonia diversifolia contains allelochemicals
that ...
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Invasive plant species when introduced into new environments may result into a number of
ecological problems (Howard et al., 2000). They may influence other species through
pathways such as allelopathy or phytotoxicity ...
Growth changes of seven Amaranthus (spp) during the vegetative and reproductive stages of development as influenced by variations in soil water deficit
(International Journal of Research and Innovations in Earth Science, 2015)
Soil water deficit is a principal a biotic factor that limits plant growth and development in dry areas. Insufficient moisture contributes to soil water deficit and some negative effects on Amaranthus (spp) such as reduced ...
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Science+ Business Media Dordrecht, 2015)
Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ...
Chlorophyll fluorescence parameters and photosynthetic pigments of four Glycine max varieties under Aluminium chloride stress
(PSCI Publications, 2015)
Soil acidity limits agricultural production globally. Different kinds of
stresses, mainly Al stress, generated from acid soils affect plant growth and
result in food shortage and production. General effects of Al toxicity ...
