Abstract: The southern root knot nematode (Meloidogyne incognita) is one of the highly polyphagous species of many cultivated plants. The losses associated with RKNs in small holder vegetable farms are not quantified but may range between 30-100% in tropical and subtropics. Application of broad spectrum nematicides is the common method of control and are to be highly toxic to humans and pollute the environment, hence the need for safer alternatives for small scale crop production systems. Bi...
ABSTRACT The aim of this study was to determine the nutrient and phytochemical composition of fresh, sun and shade dried okra, bitter, scent, G. latifolium and roselle leaves. The vegetables were purchased from two markets. Okra, bitter, scent and G.latifolium leaves were purchased from Nsukka and roselle leaves were bought from Jos market. All the vegetables were washed, weighed and divided into two equal parts. Each part was sun, or shade dried, pulverized, packed and stored. The fresh samp...
ABSTRACT The radionuclides present in soil, water and selected foodstuffs taken from all the thirty local government areas of Osun State have been identified and their activity concentrations measured in order to calculate, the absorbed dose, collective effective dose equivalent and committed effective dose for the estimation of the potential biological risk/damage of naturally occurring radionuclides in the State. One hundred and twenty six samples each of soil, water, yam flour, cassava flo...
Abstract: Globally, orange is one of the major fruit crops contributing to nutrition and monetary income. False codling moth (FCM), Thaumatotibia leucotreta, is one of the major constraints of orange production. Before this study, little was known regarding the bioecology of FCM in orange and vegetables in Kenya and Tanzania and the potential use of dry conidia of entomopathogenic fungi for control of T. leucotreta moths has not been tested. There is also no IPM strategy available for FCM in...
ABSTRACT Envirodome greenhouse technology has become a widely accepted and profitable system for vegetable production particularly in Ghana. However, plant varieties best suited for the Envirodome have not been fully exploited in Ghana. Thus, an experiment was carried out at the Forest and Horticultural Crops Research Centre (FOHCREC), Okumaing-Kade in Ghana from July 2018 to April 2019 to assess eight different types of tomato for some morphological and yield attributes under Envirodome gree...
ABSTRACTThe word perfume derives from the latin ―per fumum‖ meaning through smoke, is fragrant liquid that is sprayed or rubbed on the skin or clothes to give a pleasant smell. Extraction of perfume from various plants resources is of ancient origin. Infact the natives from different tropical regions of the globe have long been extracting oil from numerous oil bearing plants. Human since the ancient time have known how to extract oil from their natural resources. Vegetable oils are natura...
Pumpkin is an indigenous vegetable with huge potential to provide nutrition, food security and income to households in Kenya but its production remains low. The crop has been given little attention in research and has not been promoted as a viable enterprise. Literature indicates that socio-economic factors and farming constraints in pumpkin production, consumption and marketing by smallholder farmers in Eastern and Central Kenya have not been studied nor documented. This research was carrie...
ABSTRACT This project was carried out to ascertain whether the local palm oil met the required standard. The analytical test carried out include the free fatty acid test the acid value, iodine value moisture, content, saponfication value, peroxide value, specific gravity, colour and viscosity. The specific gravity of the oil sample was determined by comparing its weight when filled with the sample and that of water, while its moisture content was analyzed by oven drying the sample for a p...
ABSTRACT Background: Vegetable oils are used either in the raw state or heated in the preparation of foods worldwide. Due to the nutrition transition, there is increased demand for fast cooked foods or convenience foods which involves the use of heated and repeatedly heated oils. Research has demonstrated that high temperature cooking with oils can result in the formation of mutagenic compounds that on consumption may induce the development of cancers. This study aimed at determining the muta...
ABSTRACT Untreated wastewater contains pharmaceutical compounds and heavy metals harmful to human health and the environment. People get access to untreated water through broken sewer pipes, blocked manholes and direct disposal into rivers. One such river is the Ngong River which passes through Nairobi County including Njiru and Ruai. People use untreated wastewater for growing of vegetables and washing cars. Soils and vegetables grown or irrigated with untreated wastewater may contain high l...
ABSTRACT In sub-Saharan Africa, tomato is an important vegetable crop as it greatly contributes to the incomes of smallholder farmers. Tanzania is among of the African countries where tomato farming contributes to the income generation of small farmers. This study sought to establish the contribution of tomatoes farming in livelihood of small farmers in Kilolo District. Specifically the study aimed to asses tomatoes farming practices, to establish the contribution of tomatoes farming in inco...
ABSTRACT The study analysed the marketing of dry season vegetables in South-East Nigeria. This study was carried out with five specific objectives. The specific objectives included (i) description of the channel, as well as the analysis of the structure and conduct of marketing of dry season vegetables in South-East Nigeria; Objective (ii) determined the marketing margins of dry season vegetables marketers; (iii) determined the effect of the constraints on the margins of dry season vegetable...
ABSTRACT Micronutrient deficiencies pose major health challenges in many African countries with certain population groups such as women of reproductive age being at a greater risk. African leafy vegetables form part of local agricultural biodiversity and have been part of the daily livelihoods of the local populations for many years. These vegetables hold promise in addressing micronutrient deficiencies if their supply and consumption are scaled up through the right application of appropriate...
ABSTRACT African Indigenous Vegetables form an integral part of the Kenyan diets, among the most commonly consumed being the African nightshade. These vegetables contain important phenolics that have medicinal values and good health attributes. The abundance of these phenolic substances has strongly been associated with phosphorus use efficiency. In order to investigate the effect of phosphorus stress on African nightshade distribution, a purposive research was done from February 2014 on 70 ...
ABSTRACT The consumption of fruits and vegetables plays a significant role in human nutrition. Students are more inclined towards taking empty calorie foods with little consideration for healthy foods, especially fruits and vegetables. This has the tendency of pre-disposing them to obesity, dental caries, and other non-communicable diseases in later years. There is a dearth of information on consumption of fruits and vegetables as part of healthy eating among secondary school students. This s...
