ABSTRACT There has been no research on gender roles and the triple burden of women in the Rehoboth area. Yet women in Rehoboth as many elsewhere are faced with socially ascribed roles in production, reproduction and community. This research seeks to explore and understand the gender division of labour and the gender relations within this community. As a diverse country, Namibia has different cultures, we witness that women and men are taught their gender roles through the use of specific cul...
French bean (Phaseolus vulgaris L.) is an important export vegetable crop that faces serious production challenge due to Ascochyta blight (Phoma exigua). The objectives of this studywere to determine the; (i) antifungal activities of methanol extract of Leonotis nepetifolia and Ocimum gratissimum against Phoma exigua in vitro, (ii) fungicidal effects of extracts of the two test plants on the incidence and severity of Ascochyta blight, and yield of French bean. Methanol extracts of compo...
ABSTRACT Soybean is one of the most important sources of protein and vegetable oil in the world. The demand for soybeans in Kenya is high yet production is negligible due to various challenges, one of which is lack of a well-organized soybean seed system. Soybean seed has been known to deteriorate rapidly in the tropics but the rates vary with the environment, initial quality of the seed and genotype. The broad objective of the research was to enhance soybean seed longevity and vigor through ...
Solar powered systems have been built for various applications ranging from public lighting to water supply units but robust efforts have not been made in the development of pumping systems that can effectively replace the manually operated pumps used in field applications. Designing a machine that can pump the fluid without the need of so much energy on the part of the operator as well as boycott the use of direct electricity will hence be a reasonable contribution to field of maintenance an...
ABSTRACT Water scarcity is globally getting worse in the light of increase in demand for water use. Human and ecosystem health and economic development are affected by problems of water scarcity and water pollution. This study was carried out to assess the current net benefit of water resource in different land uses around the Kilombero Valley Ramsar Site in Tanzania. Specifically the study was conducted to identify different land uses related to water, to determine and estimate costs and ben...
Abstract Petroleum based detergents are neither soluble nor biodegradable; they are so stable such that when they flow into the soil, sewer or surface waters, they remain unchanged, resisting conversion into less complex and more soluble substances. In this work methyl ester sulphonate (MES) was produced by transesterification followed by sulphonation of ricinoleic acid, a main constituent of castor oil. A detergent was produced from transesterification followed by sulphonation of castor oil ...
ABSTRACT The oldest system of tanning relies on the chemical action of vegetable materials containing tannin and tannic acid on the protein constituents of skin or hides.
Abstract Slender leaf (Crotalaria spp) is among the indigenous and underutilized vegetables in Kenya whose production is limited to the Western and Coastal regions of the country. For a long time, this crop has been neglected in terms of research and genetic improvement. *ere is therefore scanty information on its morphological diversity and agronomic performance, hence the need for this study. Field experiments were carried out for two seasons in October to December 2018 and March to May 20...
ABSTRACT Feed shortage, especially during dry seasons, is a critical threat to livestock production in Namibia. Innovative feed production from encroacher bush species has the benefits of increasing fodder availability and controlling bush encroachment. Bush-based feed is characterized by high fibre and low protein content which makes it less palatable and digestible to livestock; hence often requires supplementation with commercial feed ingredients which increase bush feed production costs...
ABSTRACT Nigeria is experiencing technical economic recession which has led to mass unemployment. As such, this study was conducted to assess the batik technique and how it can be applied in the process of bag making as a means of self sustenance. Batik which is regarded as a versatile medium for artists offers immense possibilities as the patterns are applied by actual drawing rather than by weaving with thread to create colourful and more elaborate designs with complex images. This has acco...
ABSTRACT The study examined the economic analysis of effects of pests and disease on small scale maize producers in Akinyele Local Government Area, Oyo state. The objectives of this research work are to determine the socio-economic characteristics of the respondents, the cost and return of maize production and also the factors that influence profitability due to pests and disease on maize production in the study area and necessary recommendation were made. A total of 100 farmers were randomly...
ABSTRACT Cabbage is an important crop for many smallholder farmers in Africa and Asia, due to its nutritional and financial benefits. It is one of the popular vegetables consumed and cultivated by both urban and rural dwellers in Ghana. The production of cabbage in Ghana, however, is faced with numerous constraints especially insect pest infestations. Farmers have limited control options and therefore resort to the use of synthetic insecticides. Indiscriminate use of these insecticides has l...
ABSTRACT African indigenous leafy vegetables (AILVs) contribute significantly to improved nutrition and food security. However, the potential to meet the growing demand for AILVs has not been met. This study determined the effect of agronets on growth, yield and nutritive values of African nightshade and spiderplant. The experiment was laid on a RCBD, replicated thrice. Blue, gray, white, yellow agronets and uncovered plants (control) were used as the treatments. Spiderplant was direct seeded...
ABSTRACTCyanide toxicity is of public health concern. Cyanide is among the most potent and deadly poisons and sources of potential human exposure to it are numerous, arising through its release into the environment from both natural and anthropogenic sources. Gnetum Africanum (GA) and Ocimum Gratissimum (OG) which contain essential amino acids required to abate cyanide toxicity effects, are widely used local plants for both nutritional and therapeutic purposes in Nigeria. There is dearth of i...
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...
