Abstract: Tomato (Solanum lycopersicon L), is one of the most common and important vegetable crops in the world with over 18,477 hectares under tomato production in Kenya. Tomato production is however, greatly threatened by bacterial wilt (BW). Bacterial wilt, caused by Ralstonia solanacearum is a serious disease in the tropics and subtropics, causing severe losses in many agricultural crops. To control its infection, several measures have been deployed but with minimum success. Alternative ...
Abstract: French bean is the most important export vegetable crop cultivated in Kenya. Pests and diseases are the major constrains to its production. The major pests of French beans are bean flies, thrips, and bean aphids. Amongst these pests, thrips are the most notorious and account for 63 – 68% yield loss of fresh marketable pods. Frankliniella occidentalis is the most widespread thrips species which has developed resistance to the commonly used synthetic pesticides. Farmers rely heavil...
This seminar report provides an in-depth examination of the microorganisms causing soft rot of tomato. Tomato (Solanum lycopersicum) is a red edible fruit having many varieties which are widely grown, often in greenhouses in cooler climates and open fields. It is consumed in diverse ways, including raw, as an ingredient in many dishes and sauces, in drinks and as a vegetable for culinary purposes. Diseases are a major limiting factor for tomato production. Diseases can be classified into two ...
ABSTRACT The study investigated the nutrients and phytochemical compositions of some leafy vegetables in Nigeria (Hibiscus cannabinus, Adansonia digitata, Sesamum indicum and Cassia tora leaves) and the effects of their extracts on blood glucose and lipid profile of alloxan induced diabetic rats. Two kilogrammes of each of the vegetables were bought fresh, sorted by removing extraneous material, washed with deionized water and separately pulverized using Gallenkamp mixer Kenwood –MPR 201. ...
ABSTRACT Cucumber (Cucumis sativus L.) belongs to the Cucurbitaceae family. It is a major vegetable crop worldwide and develops rapidly, with a shorter time from planting to harvest than most crops. It is a monoecious annual climber or creeper that has been cultivated for over 3,000 years and is still widely cultivated today. The fruit is soft, succulent with high water content, roughly cylindrical and elongated with tapered ends. The plant shades one another, being allowed to creep on the ...

ABSTRACT Poultry products are among the most valuable sources of animal protein, and offer a means of meeting the animal protein needs of the population. Compounded poultry feed, physical inactivity of the birds due to overcrowding and certain unhealthy habits like pecking are major setbacks to intensive poultry production. The result is high cost and high cholesterol content of products. The later has been a cause for concern to health-conscious consumers. High blood cholesterol levels have ...
Vitamin deficiencies are health hazards in some parts of Kenya. These are attributed to inadequate access to vitamin-rich foods occasioned by decline in agricultural production due to unfavourable climatic conditions, low purchasing power due to poverty, over reliance on staple foods and dependence on highly refined foods, which are poor in vitamins. Higher intake of vitamin-rich vegetables and grains can alleviate this problem. Grain amaranth (GA), which is relatively a new crop in Kenya, is...
Tomato (Solanum Lycopersicun L) is a very important vegetable grown mainly by small scale farmers in most arable areas in Kenya. Tomato production has declined drastically due to attack by Ralstonia solanacearum, a soil borne pathogen which causes bacterial wilt. Transmission of pathogen occurs when bacterial ooze from the plant enters the surrounding water or soil, contaminates farming equipment or by insect vectors. The disease has not yet been effectively managed. Grafting is an asexual pl...
Tomato is a popular vegetable in Kenya and is extensively grown by small-scale farmers. In spite of the economic benefits to the farmers, insect pests remain one of the most significant constraints to tomato production. Current insect pests control measures rely on pesticides despite the known hazards to human health and the environment. Repeated use of pesticides has also led to the development of resistance by pests. Therefore, it is important to evaluate other pest control strategies ...
ABSTRACT Green pepper (Capsicum annuum) is one of the most important and remunerative vegetable crops. Row spacing and mulching are important factors that influence water use, weed suppression, growth, quality, and yield of vegetables. Due to increased pressure on land, climate change and increased demand for vegetables, there is need for deployment of optimal agronomical practices that will ensure enough food production. This study was undertaken to determine the optimum spacing and mulching...

ABSTRACT Tomato production in Kenya, especially in the coastal region has remained low due to pests and diseases attack especially Meloidogyne spp. (root-knot nematodes) which is a serious threat. A study was therefore conducted in the coastal region of Kenya with the aim of sourcing for endophytic fungi (EF) which could be used alongside moderately resistant tomato cultivars to manage Meloidogyne spp. Pathogenecity test of these isolates was carried out in the screenhouse using cv. Cal J. In...
ABSTRACT Amaranths are African indigenous vegetables (AIVs) that have recently gained importance as a food source in Africa owing to the high nutritional value of their leaves and grains. Production of this crop is, however, limited by arthropod pests especially the lepidopteran leaf-webbers, leaf-worms and stem weevils. The use of insecticides for their management is uneconomical and also present health and environmental concerns. Host plant resistance (HPR) to insects is an effective, econ...
ABSTRACT French bean (Phaseolus vulgaris L.) is an increasingly important vegetable crop in Kenya accounting for a significant proportion of foreign exchange earned from horticulture. Farmers in Kenya experience insufficient and unreliable rainfall that affects yields and subsequent family incomes. Attempts to address this situation have been further hampered by poor rainfall distribution. Integration of plant growth regulators in French bean production are among the options that have been su...
