Effect of plant biomass, manure and inorganic fertilizer on maize yield in the central Highlands of Kenya
(2007)
Soil fertility degradation remains the major biophysical cause of declining per capita crop production on smallholder farms in sub-Saharan Africa. Appropriate soil fertility regimes, are therefore, critical for improved ...
Isolation and characterization of bacillus species from soil in Ngere tea catchment area of Murang’a county, Kenya
(2014-07)
Bacteria are a very diverse group of organisms in soil, and major taxonomic groups are represented in most soils. The extent of the diversity of microorganisms in soil is seen to be critical to the maintenance of soil ...
Effects of organic and mineral fertilizer inputs on maize yield and soil chemical properties in a maize cropping system in Meru South District, Kenya
(Springer, 2007-01)
Soil nutrient depletion as a result of
continuous cultivation of soils without adequate
addition of external inputs is a major challenge in
the highlands of Kenya. An experiment was set
up in Meru South District, Kenya ...
Soil Inorganic N and N Uptake by Maize Following Application of Legume Biomass, Tithonia, Manure and Mineral Fertilizer in Central Kenya
(Springer Netherlands, 2011-05)
In the smallholder farms of central Kenya soils suffer from nitrogen (N) deficiency due to
inability to replenish it through application of chemical fertilizers and/or manure. This study
evaluated the effect of some ...
Potential of indigenous bradyrhizobia versus commercial inoculants to improve cowpea (Vigna unguiculata L. walp.) and green gram (Vigna radiata L. wilczek.) yields in Kenya
(2012)
Limited information is available on reduced cowpea (Vigna unguiculata L. Walp.) and green gram (Vigna radiata L.Wilczek.) yields in Kenya. Declining soil fertility and absence or presence of ineffective indigenous rhizobia ...
Moderating effect of government regulations on the relationship between cost recovery and financing of water investments in Nairobi peri-urban markets in Kenya
(2015-02)
Over the last 200 years, most water
utilities have been publicly owned and
managed. For this reason, public utility
firms have been getting financial support
from the government in form of ...
Complete genome sequence of the gliding freshwater bacterium Fluviicola taffensis type strain (RW262T)
(2011)
Fluviicola taffensis O'Sullivan et al. 2005 belongs to the monotypic genus Fluviicola within the family Cryomorphaceae. The species is of interest because of its isolated phylogenetic lo-cation in the genome-sequenced ...
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-10)
The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ...
Long-term effects of tillage, sub-soiling, and profile strata on properties of a Vitric Andosol in the Kenyan highlands
(2008)
Tillage alters the structure and composition of soil aggregates affecting infiltration rate (IR) and hydraulic conductivity (K). This study investigated the long-term effects of conventional, minimum, and no-tillage with ...
Mitochondrial DNA variation of Bemisia tabaci (gennadius) (hemiptera: aleyrodidae) infesting cassava in Kenya
(2011)
Bemisia tabaci is a widely distributed crop pest affecting the yield of a broad range of agricultural, fiber, vegetableand ornamental crops. It is an extremely polyphagous pest that causes direct damage and can act as a ...
