ABSTRACT Determination of genetic variability among genotypes is highly desirable for selection towards crop improvement and production. The main objective of this study was to evaluate variability in agro-morphological and fruit quality traits in seventeen (17) hot pepper genotypes under greenhouse and field conditions. The experiment was laid out in Randomized Complete Block Design with three replications under greenhouse and field environments. The estimation of genetic variance under in...
ABSTRACT The study analyses the effects of intersectoral labour mobility between agricultural and non-agricultural sectors on deforestation in Ghana. It is based on annual time series data covering the period 1970—99. The study describes the basic determinants of intersectoral labour mobility and deforestation and estimates the magnitudes o f the effects of their determinants in Ghana. The empirical results show that the effects of intersectoral labour mobility between agricultural and non...
ABSTRACT In Togo, the quantity of rice produced is very low compared to the needs of the country. Farmers and consumers prefer aromatic rice. The main objective of this research was to increase the local production and supply farmers with aromatic and higher yielding varieties. It was conducted to lay the foundation of a rice breeding programme in Togo. Therefore, the research investigated farmers’ preferences and production constraints, established a germplasm collection and studied its g...
ABSTRACT Livestock development projects are aimed at increasing livestock productivity and increasing household incomes of participating livestock farmers and processors and traders in Ghana. Ghana has implemented two of such projects within the last two decades: The “National Livestock Services Project” and “Livestock Development Project”. The components of these projects were development of animal production, development of animal health, credit provision, and capacity building. T...
ABSTRACT Milk, fat and protein first lactation records of 27,137 British Columbia Dairy Herd Improvement cows were analysed for gross genetic and environmental influences. The average production was 5,663 kg of milk containing 3.59% fat and 3.23% protein. Age at freshening accounted for 3.0, 3.7, 3.7, 0.28 and 0.15% of the variance in milk, fat, protein, percent fat and percent protein respectively. Cows freshening in the winter had higher average milk, fat and protein yields than those fres...
ABSTRACT The indigenous guinea fowl plays a vital role in the agricultural industry as both its meat and eggs are healthy, tasty and serve as an important protein source for consumers. However, genetic progress on this bird has been partially hindered by the absence of polymorphic markers, especially microsatellites. Therefore, this study developed for the first time original microsatellite markers for this economically important species. The 454 sequencing technique (next-generation sequenc...
ABSTRACT The unavailability of adequate empirical data necessitated this study of analysis of rural farmers‟ use of improved cocoyam production practices in South-South, Nigeria with coverage States such as Cross River, Delta and Edo. The study described the socio-economic characteristics of rural farmers, identified the improved cocoyam production practices and determined the extent of rural farmers‟ use of improved cocoyam production practices among others. A total of 411 contact cocoya...
ABSTRACT A research was conducted from June 2008 to May 2009 with the main objectives to identify suitable hot pepper lines to be used in breeding for superior fruit yield and yield associated components based on their combining abilities, determine heterosis in the Fi generation, estimate heritability of various traits and correlation between yield and its associated characters. Eight (8) hot pepper lines were analysed in a line x tester fashion comprising six (6) lines and two (2) testers. ...
ABSTRACT This study assesses the profit efficiency of layer production in the Brong Ahafo and Greater Accra Regions of Ghana. The study specifically used farm level data to estimate the level of productivity of various inputs, profit efficiency levels, identify determinants of profit efficiency and further identified and ranked major constraints to layer production using Henry Garrett’s ranking technique. A multi-stage sampling technique was used to collect cross-sectional data from 300 lay...
ABSTRACT The main objective of this study is to assess the causes of labour migration, low food crop production and remittance linkages on the livelihood of rural households in the Kpando District. The researcher used survey design to elicit information from 202 heads of non-migrants’ households within the study area. The households used for the study were selected by cluster sampling and information was elicited from them through personal interview and a structured questionnaire. Data for ...
ABSTRACT Several studies have revealed that towards the east of Accra, there is no lymphatic filariasis (LF) but it occurs to the west of Accra. Anopheles melas is known to be an efficient vector of LF and it occurs along the coastal part of Ghana, especially in estuarine areas. The present study therefore aimed at seeking explanation to why this different patterns of LF distribution occur along coastal Ghana. The hypothesis was that the eastern An. melas populations could be different from t...
ABSTRACT The study is aimed at assessing the effect of processing techniques on physical attribute, storage and nutritional composition of wild mushroom (Termitomyces spp) and oyster mushroom (Pleurotus ostreatus) at the Nutrition Laboratory of Noguchi Memorial Institute, Legon. A structured questionnaire was used to collect information on farmer’s methods of harvesting, managing and reducing postharvest losses of wild mushrooms. The questionnaire was pre-tested on 50 participants that were...
ABSTRACT The increased need for energy self-sufficiency has caused an extensive search for various sources of energy (especially, oil and gas) in the marine environment. Globally, the magnitude of impacts of the activities on the marine environment is increasing over the years and most felt on the seafloor. The study of seafloor (benthic) organisms therefore, are vital determinants of impacts on the seafloor. This thesis sought to determine the community structure of nearshore and offshore be...
ABSTRACT A study on the use of bovine colostrum as an alternative source of immunoglobulin for lambs was carried out at the University of Ghana’s Agricultural Research Centre — Legon. The study involved a total o f fifty-six lambs. Thirty-three of them were bottle-fed with frozen bovine colostrum that was thawed whilst the remaining (twenty-three) were allowed to suckle their dams and served as the control. The mean serum immunoglobulin concentrations for the two groups of lambs were meas...
ABSTRACT Six extra-early QPM inbred lines from IITA were investigated using a partial diallel cross design. The objectives were to assess the hybrids and their parents for their agronomic performance. The six parents along with their hybrids (15) were evaluated using a Randomized Complete Block Design (RCBD) with three replications per site in four locations. Genetic correlations, general combining ability (GCA) and specific combining ability (SCA) effects as well as mid-parent heterosis were...
