Mycorrhiza co-association with Aspilia pruliseta Schweif. and phosphorus uptake effects on growth of gadam sorghum in the semi-arid lower Eastern Kenya
(Academic Journals, 2020-08)
Mycorrhiza fungi are important components of soil microbiota in the rhizosphere and greatly influence
the uptake of mineral elements by plants. A greenhouse experiment was conducted at the University of
Embu to evaluate ...
Dissemination of Integrated Soil Fertility Management Technologies Using Participatory Approaches in the Central Highlands of Kenya
(Springer Netherlands, 2011-06)
Declining soil fertility and productivity is a critical problem facing smallholder farmers in the central highlands of Kenya. A study to improve soil fertility and farm productivity within the smallholder farming systems ...
Predicting decomposition patterns of tree biomass in tropical highland microregions of Kenya
(Kluwer Academic Publishers, 1997)
Decomposition- and nitrogen-release patterns of biomass from three agroforestry multipurpose trees (Calliandra calothyrsus, Cordia africana and Grevillea robusta) were investigated in four contrasting environments ...
Household's socio-economic factors influencing the level of adaptation to climate variability in the dry zones of Eastern Kenya
(Elsevier, 2015-11)
Climate variability has a negative impact on crop productivity and has had an effect on many small-holder farmers in the arid and semi-arid lands (ASALs). Small-holder farmers in Eastern Kenya are faced with the constraint ...
Decomposition of Cassia siamea loppings in semiarid Machakos, Kenya
(1994)
The rate of decomposition of Cassia siamea Lam. prunings in an alley cropping system was investigated using litter bags in the semiarid area of the Machakos District, Kenya, during the short rains of 1988 and the long rains ...
Conservation tillage, local organic resources and nitrogen fertilizer combinations affect maize productivity, soil structure and nutrient balances in semi-arid Kenya
(Springer, 2011-01)
Smallholder land productivity in drylands can be increased by optimizing locally available resources, through nutrient enhancement and water conservation. In this study, we investigated the effect of tillage system, organic ...
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 ...
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 ...
Alley cropping of maize with calliandra and leucaena in the subhumid highlands of Kenya Part 2. Biomass decomposition, N mineralization, and N uptake by maize
(Kluwer Academic Publishers, 1999-06)
A major challenge in developing agroforestry approaches that utilize tree-leaf biomass for provision of N to crops is to ensure synchrony between the N released from decomposing prunings and N demand by crops. A study was ...
