Adapting African Agriculture to Climate Change
Kisaka, Oscar M.; Mucheru-Muna, M.; Ngetich, F.K.; Mugwe, Jayne; Mugendi, Daniel N.; Mairura, F. (Springer, 2015)Drier parts of Embu County, Eastern Kenya, endure persistent crop failure and declining agricultural productivity which have been attributed, in part, to prolonged dry-spells and erratic rainfall. Nonetheless, understanding ... -
Effects of selected soil and water conservation technologies onnutrient losses and maize yields in the central highlands of Kenya
Okeyo, A.I.; Mucheru-Muna, M.; Mugwe, Jayne; Ngetich, F.K.; Mugendi, Daniel N.; Diels, J.; Shisanyaaa, C.A. (Elsevier, 2014-02)tMitigating nutrient loss is a prerequisite of sustainable agriculture in the tropics. We evaluated threesoil and water conservation technologies (mulching, minimum tillage and tied ridging) for two croppingseasons (long ... -
Length of growing season, rainfall temporal distribution, onset and cessation dates in the Kenyan highlands
Ngetich, F.K.; Mugendi, Daniel N.; Mucheru-Muna, M.; Mugwe, Jayne; Shisanya, C.A.; Diels, J. (Elsevier, 2013-12)Dependence on uncertain rainfall and exposure to unmitigated climate risk are major obstacles in efforts to sustainably intensify agricultural production and enhance rural livelihoods. There is generally enough seasonal ... -
Phosphorus availability and exchangeable aluminum response to phosphate rock and organic inputs in the Central Highlands of Kenya
Omenda, Jane A.; Ngetich, F. K.; Kiboi, Milka N.; Mucheru-Muna, M.; Mugendi, Daniel N. (Heliyon, 2021-03)Soil acidity and phosphorus deficiency are some of the constraints hampering agricultural production in tropical regions. The prevalence of soil acidity is associated with phosphorus (P) insufficiency and aluminum ... -
Potential of deterministic and geostatistical rainfall interpolation under high rainfall variability and dry spells: case of Kenya’s Central Highlands
Kisaka, Oscar M.; Mucheru-Muna, M.; Ngetich, F.K.; Mugwe, Jayne; Mugendi, Daniel N.; Mairura, F.; Shisanya, C.A.; Makokha, G. L. (Springer, 2015-03)Drier parts of Kenya’s Central Highlands endure persistent crop failure and declining agricultural productivity. These have, in part, attributed to high temperatures, prolonged dry spells and erratic rainfall. Understanding ... -
The Potential of Organic and Inorganic Nutrient Sources in Sub-Saharan African Crop Farming Systems
Ngetich, F.K.; Shisanya, C.A.; Mugwe, Jayne; Mucheru-Muna, M.; Mugendi, Daniel N. (2012-02) -
Rainfall Variability, Drought Characterization, and Efficacy of Rainfall Data Reconstruction: Case of Eastern Kenya
Kisaka, Oscar M.; Mucheru-Muna, M.; Ngetich, F.K.; Mugwe, Jayne; Mugendi, Daniel N.; Mairura, F. (Hindawi Publishing Corporation, 2015)This study examined the extent of seasonal rainfall variability, drought occurrence, and the efficacy of interpolation techniques in eastern Kenya. Analyses of rainfall variability utilized rainfall anomaly index, coefficients ... -
Using Apsim-Model as A Decision-Support-Tool for Long-Term Integrated-Nitrogen-Management and Maize productivity under Semi-Arid Conditions in Kenya
Kisaka, Oscar M.; Mucheru-Muna, M.; Ngetich, F.K.; Mugwe, Jayne; Mugendi, Daniel N.; Mairura, F.; Muriuki, J. (Cambridge University Press, 2015-04)There is continued decline in per capita agricultural productivity in the drier parts of Kenya’s central highlands. The declines have been linked to low and declining soil fertility, soil water, high atmospheric heat, ...
