Household's socio-economic factors influencing the level of adaptation to climate variability in the dry zones of Eastern Kenya
Mugendi, Daniel N.; Mugi-Ngenga, E.W.; Mucheru-Muna, M.W.; Mugwe, Jayne; Ngetich, F.K.; Mairura, F.S. (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 ... -
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 ... -
Long-term effects of tillage, sub-soiling, and profile strata on properties of a Vitric Andosol in the Kenyan highlands
Ngetich, F.K.; Wandahwa, P.; Wakindiki, I. (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 ... -

Microbial biomass and acid phosphomonoesterase activity in soils of the Central Highlands of Kenya
Kiboi, Milka N.; Ngetich, F.K.; Mugendi, Daniel N.; Muriuki, A.; Adamtey, N.; Fliessbach, A. (Elsevier, 2018-12)Soil biological properties are the most sensitive soil quality indicators that respond quickly to short-term soil fertility management changes. We studied the combined effects of tillage and soil external inputs on total ... -
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, Monicah; Ngetich, F.K.; Mugwe, Jayne (Springer Vienna, 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 ... -
