ABSTRACT This thesis evaluated the self-reported health effects of xenobiotics on electronic waste workers in Agbogbloshie, Accra, Ghana. In this occupational setting, many workers do not wear personal protective equipment (PPE), which exposes them to xenobiotics through inhalation, ingestion and dermal contact. The study was mainly quantitative consisting of measurements of concentrations of volatile organic compounds (VOCs) including formaldehyde and methane, and particulate matter of size...
ABSTRACT The study set out to examine the effects of human encroachment on the Sakumo Ramsar Site. Descriptive and cross-sectional designs were employed to study 102 household heads from Lahibi, Sakumono, Klagon and Tema, as well as the Director of the Wildlife Department. Interview schedules were used to collect quantitative data from household heads, while interview guide was used to solicit qualitative data from the Director of the Wildlife Department. The quantitative data were analysed ...
ABSTRACT The phenological development, growth, yield and yield stability performance of eight cowpea varieties released in Ghana between 1990 and 2015 were evaluated in field experiments carried out at Mampong-Ashanti (forest-savannah transition zone) and Fumesua (forest zone) over two cropping seasons in 2015 and 2016. The experiments were arranged in a randomized complete block design (RCBD) with three replicates. Asontem, Nhyira, Asetenapa, Hewale and Videza flowered and podded earlier (3...
ABSTRACT This study assessed rice farmers’ perception of climate change and adaptation strategies towards tackling the challenges climate change poses to the rice farmers in Ketu North District, Volta Region of Ghana. The multistage sampling technique was used to obtain a sample size of 340 rice farmers from six (6) farming sections and a structured questionnaire was used to elicit data from the respondents. The data collected from the rice farmers were analyzed using descriptive statistic...
ABSTRACT While remaining the most important sector of Ghana’s economy, agriculture in Ghana faces the challenge of making substantial progress in maintaining food security because average yields remain stagnant. This is attributable to limited use of modern inputs, such as fertilizer and improved seed, and due also to the rapid decline in Africa’s soil fertility status. Since its inception in 2008, that is six years to date, Ghana’s fertilizer subsidy programme has undergone a number of...
ABSTRACT Adult Clarias gariepinus (African Catfish) were purchased from Eleiyele Lake and Zartech fish farm in Ibadan. Water samples were also collected in February (dry season) and June (rainy season), 2002. Gill, bone, intestine, muscle and water samples were analyzed for five metals: manganese, copper, zinc, iron, and chromium by atomic absorption spectroscopy (AAS) in two separate experiments. In each case, two tissues were compared with the levels of the metals in water viz: Gill, bone, ...
ABSTRACT Mining is assuming importance in the economies of mineral-endowed developing nations. These countries have developed new minerals and mining codes to attract Foreign Direct Investment on a massive scale. The benefits and costs of mining have become a contentious issue. The study assessed the implication of mining on the livelihood of the communities affected by mining within the Teberebie Electoral Area of Wassa West District of Ghana based on the concept of sustainable development. ...
ABSTRACT For any good breeding work and its subsequent improvement, a knowledge in genetic diversity is very necessary. Genetic diversity of eighty seven Sweetpotato accessions assembled from various potential growing areas and two research institutions in the country, Crops Research Institute at Fumesua in Ashanti Region and Plant Genetic Resources Institute in the Eastern Region were put together and investigated using Morphological and Molecular characterization approaches.Both qualitative...
ABSTRACT Studies were carried out on the reaction o f some oil palm tenera progenies to Fusarium oxysporum f sp elaeidis (FOFSE) isolates isolated from the Crops Research Institute and Oil Palm Research Institute plantations, in Akumadan and Kusi respectively. Four isolates, P. 38, P.50, P.459 and P.568 were obtained from Akumadan and the remaining one, P. 93 from Kusi. The growth and cultural characteristics of the isolates were studied on Dehydrated Potato Dextrose Agar (PDA), Fresh P...
ABSTRACT The study was conducted to analyse production risk and technical efficiency of lowland rice farms in Ashanti region using adjusted stochastic production frontier. Cross sectional data for 2014 cropping season was collected from 200 sampled rice farms using multistage sampling technique. The results of the study revealed very low utilization of improved seed (42.8 kg/ha) by famers as against the standard quantity of 100kg/ha. Among the farm inputs used, fertilizer and improved ...
ABSTRACT The study examined the dissemination and adoption of cocoa production technologies in Ghana The aim was to improve cocoa extension and adoption of technologies to ensure higher yield. The study Identified twenty-five technologies and examined the communication factors that influenced the adoption of the technologies. characteristics and farm related factors were also studied. In addition. the study examined the relationships between the level of adoption of the technologies and backg...
ABSTRACT The adoption and sustained use of Integrated Aquaculture and Agriculture depends strongly on the perception of the farmers which in turn can be largely influenced by the socioeconomic attributes of the farmers. This study therefore examined the socioeconomic characteristics of fish farmers in relation to their perception and willingness to adopt integrated fish-rice and pig production system in south eastern Nigeria. Abia and Imo States were purposely selected for the study because...
Abstract A 70-day feeding trial was conducted to evaluate nutrient intake, digestibility and growth characteristics of rabbits fed maize grain (mg), maize offal (mo), cassava tuber (ct) or cassava peel (cp) based diets. The four test ingredients were included at 30.84% in diets supplying 17% crude protein. The consumption of dry matter, crude protein and crude fibre were higher (P4.05) in mo and cp based diets, while apparent digestibilities were better (Pc0.05) in rabbits fed mg and ct based...
ABSTRACT The influence of temperature on yield and quality of three Japanese strawberry (Fragaria x anannasa Duch) cultivars („Sachinoka‟, „Benihoppe‟ and „Tochiotome‟) were studied between March and August, 2011 in a screen house at Tokyo University of Agriculture and Technology, Japan. Completely Randomised Design was used with eight (8) replications each of the cultivars. One set of treatment comprising of the three cultivars were set as control and the other treatment was se...
ABSTRACT Indigenous and traditional crops are very essential in the survival strategies of local farmers, since they have multiple uses such as a variety of plant parts that can be consumed as well as for medicinal purposes. Traditional crops play an important role in achieving food security as well as conserving biodiversity. Some of these indigenous crops (e.g. legumes) have the capacity to establish and grow relatively well on poor fertility soils where crops such as maize (a major staple...
