Trace element analysis in infant food from selected rural and urban areas in Kenya using txrf technique

The need for dietary trace elements during periods of rapid growth such as infancy and early childhood is crucial. These elements are required for promotion of good growth, health and behavioural development of an infant. Inadequate dietary intake of these elements may cause delayed sexual maturation, poor growth rate, mediocre work performance, faulty immune functioning, tooth decay and altered hormonal function, ill health and even death.

Waste-Product Utilization in Kenya

Kenya's rapid industrialization since independence has generated immense benefits and economic opportunities for many. However, as population increases, burgeoning towns and a rapidly expanding manufacturing sector have been accompanied by growth of wastes and environmental pollution. Improper disposal creates health hazards, pollution of the environment and resource waste. In this respect, waste disposal has generated widespread concern, calling for need to salvage and re-use waste resources by adopting economically viable waste disposal practices.

Peasant mode of production and low productivity: : a study in Buhoma district, Ruhengari province of Rwanda

The different ways in which peasant use their available resources to produce both social and material products have for long thought to associated with low productivity. The farm inputs used and the activities as well as practices involved in peasantry production process were either said to contribute to low agricultural production or to affect the individual's ability to produce. The main objectives of this study were to look into how the farm inputs used in peasant mode of production, including land use and cropping patterns in Buhoma district contribute to low agricultural production.

Determinants of farmers’ awareness about crop insurance: evidence from Trans-Nzoia county

Kenya has a long history in applying risk management mechanisms in agriculture. The initial agricultural insurance scheme was initiated by the colonial government in the 1930’s under the Guaranteed Minimum Returns (GMR); a form of crop insurance that guaranteed farmers a minimum price for their produce besides insuring their production against unavoidable crop failure. However, due to its abuse by stakeholders, the government made a decision to discontinue the programme in 1978. For many years after the discontinuation, agricultural insurance was virtually not available in the country.

Phosphate sorption isotherms of selected soils of Kenya and maize response to phosphate fertilizer in the greenhouse

Phosphate sorption characteristics of eight selected soils of Kenya were determiner order to establish the influence of previous manure and phosphate (P) fertilizer applications. The soils were two ando-humic Nitisols, orthic acrisol, humic Nirisol, dystromollic Nitisol, mollic Nitisol and a ferralo-chromic Acrisol. A greenhouse experiment with maize was performed to determine the external P requirement for maximum dry matter yield (DMY) of eight-week old plants.

Evaluating The Agronomic Effectiveness Of Human Faecal Compost On Maize Yields, Its Influence On Soil Chemical Properties And Soil Fauna Abundance

Low soil fertility status has been stated as the main cause of poor crop yields in many sub-Saharan countries. This challenge can be addressed by using cheap and readily available options. One such option is human excreta. Human excreta contain millions of tons of nutrients. It is estimated that in a year, humans excrete an equivalent of 20 -30% of global annual fertilizer industry production. Unfortunately, most of the nutrients end up in water bodies through wastewater and surface runoff.

Climate variability and livestock feeding strategies in the agro-pastoral systems of Southeastern Kenya

This study was conducted to address the problem of inadequate information on the characteristics of drylands' agro-pastoral livestock production systems and how they are adapting to the changing environments (biophysical, social, cultural, economic and technological) under increasing climate variability.

Prevalence of aflatoxin contamination in cereals from Nandi county, Kenya

Aflatoxins are secondary fungal metabolites that contaminate cereals, other crops and animal source foods and are a recognized health risk. Kenya has had several outbreaks of aflatoxicosis affecting humans and pets. The aim of this study was to compare aflatoxin levels in cereals, the staple diet of Kenyans, in Nandi where aflatoxicosis has not been reported despite being a maize growing area. Maize, sorghum and millet were sampled from households and also from markets serving various villages in the selected sub-locations (408 samples).

Rainwater Harvesting Practices, Cropping Systems And Productivity In Smallholder Farms In Laikipia Central District

Over dependence on rainfed agriculture is one of the major problems in Kenya's agricultural sector. One of the most promising solutions is upgrading rainfed agriculture through the adoption of rainwater harvesting (RWH) and its management which will improve water availability for productive purposes. However, what is not clear is the role of rainwater harvesting on household food security and the returns to the investment in the water management systems in semi-arid lands. This study evaluated smallholder farms in Matanya Location which is an area that is prone to drought.
