Differences in resource utilization in rural Kenya: a case study of a heterogeneous Settlement scheme, with particular reference to dairy farming innovation in the Nzoia Scheme, Kakamega, Kenya

This study examines the individual socio-economic and other governmental extension factors which make for differences in the levels of sustaining innovation in the Nzoia Scheme. This was a case study of a rural planned settlement scheme. in analysing the nature of resource utilization by the farmers here. we laid much emphasis on the dairy farming enterprise innovation. This was because it was considered to be a more relatively steady income generating activity for an average farmer, compared to arable fanning activities.

Managerial ability in small-farm production: an analysis of maize yields in the Vihiga Division of Kenya

The research, analysis, and drafting of this doctoral dissertation took place between May 1970 and April 1973 in the Vihiga Division of ~vestern Kenya, at the University or Nairobi, and at the Uni versi ty of I'1ichig-an.In Kenya, I was a Visiting Research Fellow in the Institute for Develop­ ment Studies, and my work was supported by a Rockefeller Foundation appropriation to the Uni versi ty of Nairobi.

Occurrence of common maize diseases in Kiambu, Embu and Nakuru counties of Kenya

Maize is an important food crop in Kenya and is consumed by over 80% of the population. Maize is produced in most regions of Kenya, including areas where it is not suited. A survey was done in different agro-ecological zones in Kiambu, Embu and Nakuru counties to determine the occurrence of northern leaf blight (NLB, Exserohilum turcicum), common rust (Puccinia sorghi), maize streak disease (Maize streak virus, MSV), gray leaf spot (Cercospora maydis), head smut (Sphaelotheca reiliana) and common smut (Ustilago maydis).

Effects of tropical ecosystem engineers on soil quality and crop performance under different tillage and residue management

Feeding a future global population of 9 billion will require a 70-100% increase in food production, resulting in unprecedented challenges for agriculture and natural resources, especially in Sub-saharan Africa (SSA). Agricultural practices that contribute to sustainable intensification build on beneficial biological interactions and ecosystem services. Termites are the dominant soil ecosystem engineers in arid to sub-humid tropical agro-ecosystems.

Evaluation of Chilo partellus and Busseola fusca susceptibility to d-endotoxins in Bt maize

Susceptibility of Chilo partellus (Lepidoptera, Crambidae) and Busseola fusca (Lepidoptera, Noctuidae) populations to Cry proteins from the bacterium, Bacillus thuringiensis (Bt), the d-endotoxins Cry1Ab and Cry1Ba in Bt-maize, were evaluated under biosafety greenhouse conditions. Larval feeding on Bt-maize was adjusted to deliver sub-lethal doses of d-endotoxins from the two events; survivors were reared on artificial diet to obtain successive generations. Eight generations of three C. partellus populations and five generations of a B.

Studies on Population densities and some aspects of Control of the common Maize Stalkborer Chilo partellus Swinhoe, C. Orichalcocililla Strand. and Sesamia calamistis Hmps

The population densities of the three coastal maize stalkborers, Chilo partellus Swin. C. orichalcoiliella Strand. and Sesamia calamistis Hmps. were estimated during the long rains of 1979, 1980 and 1981, showed the occurrence of two population peaks of different magnitudes during the years studied. There was an interchange in the pest status by the two Chilo species in different years during the experimental seasons. S.

Makueni District Profile: Crop Production And Marketing, 1988-1999

Abstract This profile describes the changes in policies affecting marketing and crop production in Makueni District since 1988. The creation of the district led to a larger market for milk and vegetables around Wote, but as yet there have been no substantial improvements in infrastructure. Liberalisation has freed up the trade in milk, grains and agricultural inputs, though the price effects are difficult to discern, due to loss of control over money supply and inflation during the 1990s. Most effects seem positive, the exception being the collapse of Makueni cotton ginnery.

The contribution of urban Household Food production to consumption, Nutrient intake, and expenditure patterns among Urban Poor in Kiambiu Slums, Nairobi

With rapid urban growth rates, a diminishing ability of many developing countries to feed the increasing national populations, persistent droughts, escalating food prices and increase in poverty, urban agriculture is increasingly becoming a food security strategy both at national and household levels. The extent, nature, and role of urban agriculture in Africa vary considerably within and between countries as well as throughout the urban hierarchy.

Substitution of milk with high-energy high-protein lactic fermented maize-bean mixture in rehabilitation of severely malnourished children

High-energy milk (HEM) consisting of cow's milk, oil and sugar is used in the rehabilitation diet of children at the Mwanamugimu Nutrition Unit. In this . study a mixture of lactic fermented maize and beans was, used as a substitute for the HEM, in a bid to reduce rehabilitation costs. The maize-bean flour containing 14.6 % protein was used to prepare a high-energy high-protein porridge (HEP), containing 15% total solids. This was liquefied using of Millet Amylase Rich Flour (ARF). The energy and protein density for the HEP was found to be 0.9 kcaljml and 0.027g Iml respectively.

Chemical Composition, Digestibility And Feeding Value Of Maize Cobs

The digestibility of treated maize cobs was studied using Romney Marsh wether sheep in a 2 × 3 factorial design; maize cobs were ground through a 10- or 6-mm screen and three chemical treatments were applied to each grinding: distilled water (control); sodium hydroxide (4.5 g per 100 g cob dry matter); and Magadi soda (9.0 g per 100 g cob dry matter). Cobs were treated for 24 h using one litre of solution per kg of maize cobs. The digestion coefficient of crude protein was lowered (P< 0.01) by finer grinding of the maize cobs.
