ABSTRACT Onion is one of the most important vegetable in Tanzania. However, yields are generally low weeds are among the major pests which reduce onion yields. A field experiment was conducted to assess the effectiveness of weed management practices in onion (Allium cepa L.) at Sokoine University of Agriculture, Horticulture unit during the dry season of October 2013 to February 2014. The experiment was laid down in a RCBD design with three replications. Three onions varieties (Red Bombay, Re...
ABSTRACT The study determined the feasibility of “Black Soldier Fly Larvae” composting and its utilization for vegetable farming in Greater Accra, Ghana. Discounted measures of project worth such as NPV, BCR and IRR were used in viability analysis. The gains obtained from replacing farmer practice with the new compost practice were estimated using the partial budget approach. Through field experimentation, the cost of using BSFL-compost and conventional fertilizer to produce lettuce for...
ABSTRACT Biodiesel, defined as the monoalkyl esters of vegetable oils and animal fats, is becoming prominent among alternatives to conventional petro-diesel due to economic, environmental and social factors. Transesterification is the most preferred method of biodiesel production. Knowledge of transesterification reaction kinetic enables prediction of the extent of the chemical reaction (or the conversion) at any time under particular conditions. It is also essential in the optimization of op...
ABSTRACT The Keta Municipality has the advantage in the production of a variety of fresh vegetables all year round through irrigation. The Municipality is known for its shallot production. However, if gains from shallot farming are not increasing to enable it compete with other produce; the system will be converted into other vegetable horticultures. This study aimed to assess how small scale irrigation is critical to the shallot value chain and the nature of relationship that exists among t...
Abstract This \ork. is aimed at developing solid base catalysts from locally sourced materials and applying them to an environmentally beneficial reactive distillation process for transesterification of vegetable oils with methanol into biodiesel. Solid base catalysts include calcium oxides (prepared from the calcinations of poultry eggshell, limestone, chalk clay and marble stone). By investigating these processed solid base catalysts samples catalytic behaviors in the transesterificat...
ABSTRACT Ghana’s urban change has been intense and rapid on several fronts over the past years. This has affected several economic activities within the urban space of which one is urban agriculture. Urban agriculture has over the years attracted attention in research due to its significance in the urban space. Notwithstanding the attention given in research, the assessment of urban farmers’ adaptation to the effect of the rapid urban change has not been given a detailed attention in lite...
ABSTRACT Organic wastes, such as faecal sludge (FS), cocoa pod husk (CPH) and empty fruit bunch (EFB) abound in large quantities in the Ghanaian environment. They contain considerable amounts of nutrients and organic matter which can be recycled to improve soil organic matter content and boost soil fertility status. This study was conducted to characterize and quantify FS produced in Sekondi Takoradi metropolis (STMA), co-compost FS with EFB and CPH, evaluate the suitability of the co-compo...
ABSTRACT Vegetable production in southern Ghana suffers grave setbacks from purple nutsedge infestation. Several attempts to identify effective and environmentally friendly management methods using the traditional weed research methods have so far not been successful. Hence, this study aimed at designing efficient and environmentally sound management methods by developing an ecological model of the population dynamics of purple nutsedge in vegetable fields. The study comprised three major pha...
ABSTRACT Atherosclerotic vascular diseases (AVDs) are presently increasing rapidly in incidence and have become key contributors to the burden of disease in most developing countries like Ghana. The condition has been projected to more than double by 2025. The type and amount of dietary fat has been associated with several disorders including AVDs and it complications. Diet, as one of the most important modifiable risk factors of Coronary Heart Disease (CHD) modulates the other known risk fac...
ABSTRACT African indigenous vegetable (AIV) farmers have limited information in the areas for training and readiness to access and produce vegetables to satisfy the growing demands by retailers in Kenya. The study assessed the readiness of women AIV farmers in Kakamega County to satisfy quality standards for high value markets (HVMs). Descriptive survey design, multistage sampling technique and interview schedule were used to collect data from 276 farmers. Observations and discussions with ke...
ABSTRACT Farmers’ access to relevant and useful agricultural information is key to improving their productivity. Research shows that the information needs of farmers differ and that the behaviour of farmers in seeking information is as varied as their production systems. The study was conducted to identify the information needs and assess the information seeking behaviour of urban vegetable farmers whose activities supplement the food needs of an increasingly urbanised population in sub-Sah...
Abstract This study is a review of sesame production in Nigeria. Data for this review was collected using primary and secondary sources. Production of sesame in Nigeria saw a tremendous increase in the last decade with an output of 80,000 metric tonnes in 2003 to about 158,000 metric tonnes in 2012. This increase was facilitated by the export of sesame seed which stood at 35,000 metric tonnes in 2003 to about 40,800 metric tonnes in 2010. Nigeria gulped a foreign exchange earnings of $19,000,...
ABSTRACT Production of Peanut Butter was done using roasted groundnuts, salt and yeast. The process involved roasting and grinding into fine paste, after which equal amount of honey and vegetable oil were added, sugar, salt, followed by powdered yolk of an egg was added as colouring agent. The product produced peanut butter was yellowish in colour, had a smooth and soft texture which spread easily on bread and had a fine peanut taste. It was put under observation for...
CHAPTER 1 1.0INTRODUCTION 1.1BACKGROUND OF STUDY Cookies are a form of confectionery products usually dried to a low moisture content (Okaka, 2009). Compared to biscuits, they tend to be larger with a softer chewer texture. They are consumed extensively all over the world as a snack food and on a large scale in developing countries where protein and caloric malnutrition are prevalent (Chinma and Gemah, 2007).With the increased advocacy on the consumption of functional foods by world nutriti...
CHAPTER ONEINTRODUCTIONDefinition: Protein hydrolysate could be defined as the end product of protein hydrolysis using chemical and enzymic methods.Protein hydrolysate have many uses in specialty foods such as non allergenic infant formular, diets foods and other special nutritional foods.The drawback of many hydrolysates such as Soya or Casein hydrolysates is the bitter taste that develops when they are hydrolysated into small peptides with protease enzymes.Protein maldigestion which...
