Genetic evaluation of growth of Dorper sheep in semi-arid Kenya using random regression models
(Elsevier, 2010-10-01)
Data consisting of 8922 weight records from 2642 Dorper sheep from 20 to 380 days of age spanning 1981–1996 were used to model the growth trajectory using random regression (RR) and estimate genetic parameters. The independent ...
NON-GENETIC SOURCES OF VARIATION IN LACTATION CURVE TRAITS OF DAIRY CATTLE IN KENYA
(2010)
Lactation curves are a graphical representation of the milk production profile of a cow from parturition to drying
up. They provide information about the productivity of the cow and offer a means of explaining features ...
VARIANCE COMPONENTS AND GENETIC PARAMETER ESTIMATES UNDER VARYING DEFINITIONS OF CONTEMPORARY GROUPS
(KARI, 2010)
A total of 19 385 test day (TD) milk yield records were used to determine the effect of contemporary group
(CG) on estimates of variance components and genetic parameters for test day milk yield (TMY) data of
Sahiwal ...
Effects of water deficit on days to maturity and yield of three NERICA rainfed rice varieties
(2010)
Water deficit is a major problem in rice grown under rainfed conditions. It affects
plant growth and development and ultimately leads to a considerable yield reduction or crop
failure. Although the rice crop is susceptible ...

Effect of Tithonia diversifolia (Hemsley) and inorganic fertilizers on maize yield on Alfisols and Ultisols of Western Kenya
(Science Hub, LLC, 2010)
Smallholder maize (Zea mays L.) farmers cannot cope with the high and ever increasing prices of fertilizers, resulting in continuous low grain yield, chronic food shortage and insecurity. Cheaper, sustainable alternatives ...
Effect of farmyard manure and inorganic fertilizers on maize production on Alfisols and Ultisols in Kakamega, western Kenya.
(JO Achieng, G Ouma, G Odhiambo, F Muyekho, 2010)
Soil acidity is one property associated with decline of most crop productivity. Alfisols and Ultisols are some of the acidic soils predominant in western Kenya. An experiment was conducted in both soils to find out the ...
Responses of ecosystem carbon dioxide fluxes to soil moisture fluctuations in a moist Kenyan savanna
(Cambridge University Press, 2010-11-01)
Measurements were conducted within a fence-exclosure between February 2008 and July 2009 to investigate the influence of soil moisture on ecosystem CO₂ fluxes in a Themeda triandra-dominated grassland of a humid Kenyan ...
Participatory consumer evaluation of twelve sweetpotato varieties in Kenya
(African Journals OnLine (AJOL), 2010)
Eleven improved sweetpotato varieties; “Kemb10, SPK004, Mugande, Namaswakhe, K117, Polista, Bungoma, Odinga, 292-H-12, Zapallo” and “Nyathi Odiewo (improved) ”, were tested against four popular farmer varieties; “Nyathi ...
Participatory evaluation of integrated pest and soil fertility management options using ordered categorical data analysis
(Elsevier, 2010-06-01)
Maize is becoming the major food crop around Lake Victoria. Major constraints to its production are Striga, stem borer, and declining soil fertility. Innovative integrated technologies have been developed: the ‘push–pull’ ...
