ABSTRACT Improved seed propagation technologies have been proposed as solution to the poor quality of seedling experienced by vegetable farmers. The use of different technologies among farmers has shown to have economic implications. This study, therefore, was carried out to assess the economic advantages of seed propagation technologies and determine constraints facing farmers in vegetable nursery management in Arumeru and Mvomero districts. The study adopted a crosssectional research desig...

It sought to ascertain the socio-economic characteristic of the melon farmers, determined cost and returns and estimation of technical efficiency of melon producers. Data were collected using questionnai...
ABSTRACT Vegetables are a major source of essential nutrients such as minerals, proteins, energy and roughage. Some vegetables such as tomato and sweet pepper can be eaten raw or cooked. These vegetables are affected by pests and diseases that are controlled using pesticides among which are fungicides such as dithiocarbamates (DTCs) that are toxic to human and animals at high concentrations. DTCs are commonly used in different combinations in Kenya and one of their metabolites, ethylenethio...
ABSTRACT The soils and leaves of fluted pumpkin (Telfairia occidentalis), African spinach, "Green" (Amaranthus hybridus) and water leaf (Talinum triangulare) were collected as randomly composite samples from four (4) different study locations of two (2) each from Owo Local Government Area and Etsako-West Local Government Area. The samples were examined for heavy metal concentrations, using X-ray fluorescence (XRF) technique. Chromium (Cr), zinc (Zn), manganese (Mn), iron (Fe), titanium (Ti), ...
ABSTRACT The study was conducted in Shinyanga Municipality, Tanzania to assess the potential contribution of peri-urban wetlands to livelihood of adjacent communities. The specific objectives were to examine the contribution of the peri-urban wetland ecosystems to natural capital– (food production/food security), evaluate the contribution of peri-urban wetlands ecosystem to financial capital –(household income) and assess the benefits received by farmer groups/associations formed around t...
Abstract/Overview African nightshades ( Solanum nigrum- related species) are some of the most widely consumed traditional leafy herbs and vegetables, particularly in Africa and South-East Asia. The leaves contain high levels of vitamins (especially A, B and C), mineral fibres (such as iron, calcium and phosphorus), carbohydrates and proteins. They also contain phenolics and alkaloids, such as nicotine, quinine, cocaine, and morphine, which are known for their medicinal attributes. With th...
Abstract: The bacterium Klebsiella pneumoniae is ubiquitous in nature and is found on the general vegetation and their fruits. The subspecies “pneumonia” is known to cause community-acquired and nosocomial pneumonia in immune-compromised persons (Ko et al., 2002; Yu et al., 2007; Yinnon et al., 1996 and Struve and Krogfelt, 2004). Some the vegetation and wild fruits form part of the staple diet or is consumed as delicacies in Botswana. The potential presence of K. pneumoniae therefore po...
ABSTRACT Preservation of food is a pre-requisite for food safety and security, bridging the gap between the site of production and site of consumption and the rising between demand and supply. There has been a problem of preserving seasonal food properly and disinfesting food without noticeable hazard to the consumer. There is also a noticeable increase in the incidence of food borne disease. The study is aimed at determine the shelf life extension of avocado, carrot, okra and tomatoes when p...

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...

Slenderleaf (Crotalaria brevidens), also known as rattle pod, is a prominent species of Crotalaria used as a vegetable in Kenya. It is a highly nutritious leafy vegetable, good sources of provitamin A, Vitamin C, carotenoids, iron protein, and calcium. At an average of 3 tons per hectare production of slender leaf in Kenya is low compared to an average potential of 11 tons per hectare. Previous studies done evaluated the influence of nitrogenous and phosphoric nutrients on slenderleaf grow...
ABSTRACT The use of quality seed is a prerequisite for high vegetable productivity. The Ghana Seed Inspection Division conducts seed quality assessment to ensure that seeds meet minimum quality standards before they are certified to be sold to farmers. Poor seed storage practices and repackaging of certified seeds at retailers’ end could adversely affect seed quality before farmers purchase these for planting. Post-certification surveillance was undertaken to assess the quality of certified...
Abstract The worldwide increase in aquaculture production and the decrease of wild fish stocks has made the replacement of fish oil (FO) in aquafeed industry a priority. Therefore, the use of terrestrial animal fats and vegetable oils, which has lower cost and larger supplies, may be good as substitute for FO. This study investigate the effects of total replacement of FO by two terrestrial animal fats (pork lard and poultry fat) and three vegetable oils (palm kernel oil, shea butter oil and s...
