Water use efficiency of maize (zea mays ) A dryland area of kenya.

This study was undertaken to investigate the variations of water use efficiency of two varieties of maize (Zea mays L.), viz. makueni and katumani composite B with planting density. and meteorological parameters under rainfed conditions. The study was conducted during the short rains season of 1990 at Kibwezi Dryland Research Station of the University of Nairobi in Machakos district, Kenya. The experimental design comprised two blocks, one for each maize variety, and three treatments characterised by Low (24,000 plants/ha), Medium (36,000 plants/ha) and High (83,000 plants/ha).

Soil nutrient content, soil moisture and yield of Katumani maize in a semi-arid area of Kenya

Many farmers in Kenya’s semi arid lands cannot afford to purchase inorganic fertilisers to improve their
crop yields. They thus rely on traditional agronomic practices such as addition of crop residues, animal
manures or intercrops of cereals and legumes. This study investigated soil parameters and their
influence on yield. It was carried out at the University of Nairobi’s Dryland, Research and Utilisation
Station located at Kibwezi. Soil parameters measured included soil organic carbon, total soil nitrogen,

An inventory guide for Samburu plant use and scientific validatIion of the pharmacological and toxicological activity of two preferentially used herbal acaricides.

Ticks resistance to acaricides is an increasing problem in Kenya and other parts of the world. It poses an economic burden due to livestock losses and enormous costs of developing novel acaricides. Traditional healers in Samburu district have utilised herbs for management of tick infestation despite the lack of scientific evidence of efficacy. The objectives of this study were to develop an inventory guide for Samburu plant use and scientifically validate the pharmacological and toxicological activity of two preferentially used herbal acaricides.

Predisposing factors to aflatoxin contamination of maize in Eastern Kenya

Maize is the staple diet of majority of Kenyan population but repeated outbreaks of mycotoxin poisoning in Eastern Kenya is a major food safety constraint. This study was conducted to determine maize production and handling practices that contribute to aflatoxin contamination in maize in Eastern Kenya. A survey was conducted in Makueni, Machakos, and Kitui districts of Eastern province during 2008 and 2009 cropping seasons.

Biological and chemical health risks associated with smallholder dairy production in Dagoretti Division, Nairobi

Approximatelyhalf of the world's population currently lives in towns and this is projected to rise to over 60% by the year 2005. The major problem facing governments is production offood supplies to feed this growing population. Urban and peri-urban agriculture (UPA) is expected to increase and contribute to feeding people in cities.

Comparison of the effects of supplementing diets of Protein Energy malnourished children at Mbooni family life training centre with milk-yellow Maize Porridge or Tempe-yellow Maize Porridge

A prospective case control study, (a clinical trial type and interventional in nature) was carried out
at Mbooni Family Life Training Centre. Effects on weight gain, growth rate, diarrhoea experience
and rehabilitation period of supplementing the diets of Protein Energy Malnourished children (PEM
children) with either bean-tempe yellow maize porridge or milk-yellow maize porridge were studied.
Using time based-quota sampling procedure a sample of 117 children, 5-60 months old who suffered

Improving Effectivity Of Newcastle Disease Vaccination And Productivity, In Indigenous Chicken, Through Effective Parasite Control

Several factors contribute to lack of effective antibody response after Newcastle disease (ND) vaccination in indigenous chicken. Stress has been shown to be one of them and parasites are thought to play a role in inducing stress. Since, in other studies, chicken in Mbeere sub-county of Embu county, Kenya, have been shown to carry heavy loads of various types of parasites, this study was carried out to establish the extent at which this parasitism affects antibody response to ND vaccination.

Epidemiology of theileriosis (with emphasis on east coast fever) and some aspects of economics of tick control in transmara division, Narok District, Kenya.

Tick-borne diseases are by far the most serious source of cattle losses in Eastern Africa. The four main tick-borne diseases, namely; East Coast Fever (ECF), anaplasmosis, babesiosis and heartwater cannot yet be routinely prevented by vaccination.
Vector control is the main practical means of controlling these diseases and this has been practised in sore parts of Kenya since 1912. This control method is reported to be expensive due to costs of dio construction, acaricides, and manpower. Complications of tick resistance also constitute an added problem.

Effect of clump planting of maize and time of planting of beans on growth and yield of intercropped maize and beans

Two field experiments were conducted at the University of Nairobi's Faculty of Agriculture Kabete, to investigate the merits of clump planting of maize and time of planting of intercropped beans on growth and yield of the maize and beans. Effect of the treatments on field weed load was also examined. Three clumping patterns of maize and three planting times of beans were tested in a factorial experiment laid out in a completely randomised block design with three replications.
