This paper presents a study on nutrient dynamics of typical farms in arid and semi-arid areas in Kenya, using the nutrient monitoring (NUTMON) research approach for assessing nutrient flows and stocks and their effects ...
Past and projected changes in rainfall and temperature over East Africa

Ongoma, Victor; Ngaina, Joshua N. (2018-07)

This study presents the past and future variations in mean rainfall and temperature over East Africa (EA) based on reanalyzed datasets, and Coupled Model Intercomparison Project Phase 5 (CMIP5). Past climate is limited to ...
Performance, soil phosphorus mobilization and rhizospheric effects of some grain legumes grown in oxisols of Western Kenya

Kapkiyai, Jane J.; Duxbury, John M. (2006-07)

Phosphorus (P) availability to crops may be affected by agronomic measures either through the modification of soil properties or through crop impact on soil P dynamics. Most legumes display one or more of the various ...
Phosphorus uptake by fallow and grain legumes from sparingly soluble P sources

Kimiti, Jacinta M.; Smithson, P. C. (SPILP, 2001)
Physics Parameterization Selection in RCM and ESM Simulations Revisited: New Supporting Approach Based on Empirical Copulas

Laux, Patrick; Kunstmann, Harald; Kerandi, Noah M. (MDPI, 2019)

This study aims at a new supplementary approach to identify optimal configurations of physics parameterizations in regional climate models (RCMs) and earth system models (ESMs). Traditional approaches separately evaluate ...
Pigeonpea phenology in sub humid and semi arid environments in Kenya

Mburu, Mary W. K.; Wanderi, S. W.; Nkonge, I. G. (2011)

Pigeonpea phenology is influenced by temperature and day length and this has adaptive value in terms ofthe crops role in food security in different ecological zones. Field experiments were conducted at sub-humid and ...
Potential challenges facing macropropagation technique in banana

Muasya, Reuben M.; Njau, Njeri; Mwangi, M.; Gathu, R.; Mbaka, J. (2011)

Objective: Bananas (Musa spp) are an important crop for food security, income for small holders and fodder among other uses. Banana production is greatly constrained by lack of affordable clean planting material. ...
Predictability of East African Rainfall Based on EL NĨNO-SOUTHERN Oscillation

Ngaina, Joshua N.; Mutai, B. K.; Gadain, H.; Muthama, N. (2017-07-26)

The El Nĩno-Southern Oscillation (ENSO) is a primary mode of climate variability in East Africa (EA). Here, the predictability of EA rainfall based on ENSO is quantified based on composite analysis, correlations and ...
Predictability of Seasonal Rainfall over the Greater Horn of Africa

Ngaina, Joshua N. (American Geophysical Union, 2016-12)

The El Nino-Southern Oscillation (ENSO) is a primary mode of climate variability in the Greater of Africa (GHA). The expected impacts of climate variability and change on water, agriculture, and food resources in GHA ...
Predicting yield outcomes in Sub-Saharan Africa using satellite observations to infer temperature, soil moisture, and yield

Ongoma, Victor; Rigden, A. J.; Akyeampong, E.; Pillai, N.; Huybers, P. J. (American Geophysical Union, 2018-12)

Sub-Saharan Africa is one of the most vulnerable regions to climate variability and change because a large percentage of people depend on rainfed agriculture for their livelihoods. Although adequate water availability is ...
Preferred Banana Varieties and their Seed Systems in Eastern and Central provinces of Kenya

Muasya, Reuben M.; Kasyoka, M. R.; Mbaka, J.; Kori, N.; Gitonga, N.; Mwangi, M. (2010-09)

Banana is an important crop for food security in Kenya. Its production has been hindered by scarcity of seedlings and pests, among other factors. A recent survey in eastern and central Kenya showed that desert varieties ...
Promoting sorghum production and use through improved seed production technologies for food security in eastern Kenya

Muasya, Reuben M.; Muui, C. W.; Kirubi, D. T. (2010-11)
Promotion of surface runoff and rainwater harvesting for application in aquaculture and horticulture development in Kitui District, Kenya: 4th National Conference to disseminate results of on-going research funded by the Kenya Government is underway in Nairobi

Kitheka, Johnson U. (2015-06-16)
Proterozoic island tectonism in the Kenyan Mozambique belt east of Nairobi

Mathu, Eliud M.; Ngecu, W. M.; Nyamai, C. M.; Davies, T. C. (1991)
Rain Water Harvesting For Improved Livestock Production Under Climatic Variability And Change In Kajiado, Kenya

Mburu, Mary W. K.; Munyao, J. N.; Kinama, J. M.; Kimenju, J. W.; Ndutu, J. M.; Mutiga, E. R. (2011-09)

One way of improving livestock health and productivity under the challenges of climatic variability and change is addressed through water harvesting technologies. A study was conducted to determine the water harvesting ...
Ramifications of variations in quality of pasture seed lots marketed in Uasin Gishu, Kenya

Muasya, Reuben M.; Motanya, W.; Gohole, L.; Ochuodho, J. (RUFORUM, 2014)

The low levels of germination, varied vigour and long periods required to attain required stand establishment in pasture fields compromises the expected quality standards of marketed seed. This study was carried out to ...
