Effects on blood pressure of reduced dietary sodium and the Dietary Approaches to Stop Hypertension (DASH) diet

Hypertension affects almost 50 million people in the United States and places them at higher risk for cardiovascular diseases.1,2 Furthermore, this risk increases with progressive elevations in blood pressure, beginning at even normal levels of blood pressure.3 The Dietary Approaches to Stop Hypertension (DASH) trial demonstrated that a diet that emphasizes fruits, vegetables, and low-fat dairy products, that includes whole grains, poultry, fish, and nuts, that contains only small amounts of red meat, sweets, and sugar-containing beverages, and that contains decreased amounts of total and s

Diversity Of Plant Parasitic Nematodes And Bacillus Subtilis Affecting Common Bean (phaseolus Vulgaris L.) In Embu Kenya

Plant parasitic nematodes cause estimated US $100 billion damage to agricultural crops. They are among the pests that threaten bean production by smallholder farmers in Kenya. The study sought to determine the presence of plant parasitic nematodes in Embu Kenya and different management techniques including strains of Bacillus subtilis, and soil fertility improvement by use of manure and inorganic fertilizer (TSP). The experimental set up included control plots with no soil amendment. The experiment was laid in a completely randomized design with 4 replications.

Response of soybean (glycine max l.) To application of inorganic fertilizers, cattle manure and lime in western Kenya

Soybean production in Kenya has remained low, partly due to soil nutrient depletion and degradation which have been considered serious threats to agricultural productivity. Studies have shown that productivity of soils in western Kenya is limited by deficiency of nutrients such as nitrogen, phosphorous and potassium a problem compounded by low organic matter and soil acidity.

Evaluating border cropping system for management of aphids (Hemiptera: Aphididae) infesting okra (Malvaceae) in Kenya.

A field experiment was carried out in 2003 and 2004 in Kenya to evaluate border-cropping system as a strategy for management of aphids infesting okra (Abelmoschus esculentus). Four crops used as border crops; maize (Zea mays), sorghum (Sorghum bicolor), pigeon peas (Cajanus cajan) and millet (Pennisetum glaucum) were planted 14 days prior to okra sowing, providing a protection perimeter around the whole plot. The number of live and parasitized aphids was monitored in situ on randomly selected leaves of okra in each plot for ten weeks.

Strategic quality management implementation practices by horticultural industry in Kenya: the case of pollen Ltd

The horticulture sector has become one of the biggest foreign exchange earners for the Kenyan economy and provides numerous Kenyans with much needed employment and income. However consumer demands on quality aspects and production methods are getting more stringent every day. To remain competitive in the global market will require horticultural industry in Kenya to embrace total quality in all its operations. Appreciation and understanding of the strategic quality management principles is pertinent towards understanding quality management of the horticultural industry.

Constraints and efficiency of cattle marketing in semiarid pastoral system in Kenya

Livestock keeping is regarded as a store of wealth for pastoralists in Kenya, besides their social and cultural functions. The objective of this study was to prioritize constraints to cattle marketing in a semiarid pastoral area of Narok in Kenya and to analyze efficiency of cattle marketing in transit markets located in Garissa, Kajiado and Narok counties. Primary data collection from traders was done through participatory interviews and market surveys, while time series market price data were obtained from secondary sources.

Gumboro Disease Outbreaks Cause High Mortality Rates in Indigenous Chickens in Kenya

Infectious bursal disease is a disease of economic importance which affects all types of chickens and causes variable mortality. To establish the importance of this disease in the indigenous chickens in Kenya a comparative study of natural outbreaks in flocks of layers, broilers and indigenous chickens was done. Thirty nine outbreak farms (5 keeping broilers, 19 keeping layers and 15 keeping indigenous flock) were visited; vaccination history collected, clinical signs observed, flock size and number of dead birds recorded.

White Lupin (Lupinus albus L. cv. Amiga) Increases Solubility of Minjingu Phosphate Rock, Phosphorus Balances and Maize Yields in Njoro Kenya

Exudation of high amounts of citrate in white lupin (Lupinus albus L. cv. Amiga) has the advantage of being effective in mobilization of a wide range of sparingly soluble P sources. To improve cultivation system of maize, a field experiment was conducted to assess effectiveness of white lupin (Lupinus albus L. cv. Amiga) in increasing solubility of minjingu phosphate rock (MPR), phosphorus balances and maize yields in Njoro sub-County, Kenya.

Impact of mobile phone-based money transfer services on smallholder agriculture in Kenya

The recent introduction of mobile phone-based money transfer services is seen to resolves one idiosyncratic market failure farmers face, namely access to financial services. It facilitates transfer of money to beneficiaries in a quick and cost effective way and offers an easy platform for the small savings and transactions. This study employs propensity score matching technique to examine the impact of mobile phone-based money transfer services on level of agricultural commercialization, input use and farm incomes among rural farmers in Kenya.
