ABSTRACT EFFECTS OF COW SIZE AND MILK YIELD ON BEEF COW PRODUCTION EFFICIENCY Gertrude S. Aboagye, M.Sc. Supervisor; University of Guelph, 1976 Dr. J.W. Wilton Data on 5 groups of cow and Angus-sired first-calf pairs representing year and season of calving subclasses were analysed within groups for effects of cow size and milk yield on 180-day weaning weight and efficiency of production. There were 15, 20, 22, 32 and 38 covrcalf pairs in groups 1 to 5 respectively. There were 3 criteria for s...
ABSTRACT An important component of Value-at-Risk (VaR) and Expected Shortfall (ES) estimation is using robust volatility models, thus the need to test the relative performance of a wide range of volatility forecasting models to ascertain the one that gives the most adequate VaR and ES forecast. Risk management has become very necessary for institutions in all sectors of an economy. Stock markets represent almost all sectors of an economy; the Ghanaian stock market being no exception. With lis...
ABSTRACT Maize is Ghana’s most important cereal crop and is grown by the vast majority of rural households. It is widely consumed throughout the country, and is the second most important staple food in Ghana, after cassava. Low soil nitrogen (N) impedes maize production in the small-scale farming sector in Ghana. Development of improved maize varieties that are tolerant to low soil N will reduce the need for nitrogen inputs and enhance production. The objectives of this study were to (...
ABSTRACT Maize (corn) is one of the most crucial and strategic cereal crops in Africa. Production occurs in all ten regions of Ghana. Despite significant improvement in food storage methods, many communities in Ghana still use traditional storage practices and structures for keeping food and seed. This has led to short falls in maize supply due to high losses and poor quality. Thus the need to determine the effect of traditional practices and storage structures on the quality of maize stored....
ABSTRACT Three experiments were conducted during the dry season from October 2001 to April 2002 at the University of Ghana Farms and the Food Research Institute, to evaluate two methods of conservation of sweet potato planting material and one method of multiplication of vines were evaluated in this study using two cultivars - Sauti and Okumkom released to farmers by the Crops Research Institute. The study was aimed at developing a technology to ensure the availability of adequate quanti...
ABSTRACT The effective planning of vector control strategies, genetic manipulation of vector species and the management of insecticide resistance require information on the population structure and the assessment of gene flow between vector populations. Although the appetitive flight of mosquitoes is known to be less than 5 km, most studies assessing gene flow between An. gambiae populations have been conducted over geographical distances as far apart as 6000km. For vector control, opera...
ABSTRACT The study investigated the occurrence of high purple beans counts of cocoa produced in Ghana. The investigation consisted of a questionnaire survey of nineteen randomly selected districts in the six cocoa growing regions in Ghana and laboratory studies at the Cocoa Research Institute of Ghana. The studies were carried out from August 2005 to October 2006. Fermentation of cocoa beans for six or seven days did not guarantee the complete removal of anthocyanins and purpleness from the ...
ABSTRACT The research was conducted to investigate the effects of High Yield Technology (HYT) biofertilizers, biochar and inorganic fertilizer on the growth and yield of pepper. The studies were conducted at the University of Ghana Forest and Horticultural Crops Research Centre (FOHCREC), Kade from May 2011 to April 2012. The experiment consisted of three factors namely, HYT, Biochar and inorganic fertilizer at three levels each (HYT: 100%, 50% and 0%); Biochar: 7t/ha, 3.5t/ha and 0t/ha; inor...
ABSTRACT Cultural practices as management strategy for beanfly control were examined over four cropping seasons in 1991 and 1992 under f a r m e r’s developed field conditions at Oyugis, in Homa Bay District of Western Kenya. In many parts of East and Central Africa, the beanfly is a major constraint to the production of the bean crop (Phaseolus vulgari s ), Its incidence causes yield losses averaging 47-87%, Control methods used against the pest are mostly insecticides based. Cultural cont...
ABSTRACT Coconut (Cocos nucifera L.) is an important cash crop in the economy of the people living in the coastal belt of Ghana, specifically Jomoro district in the Western region. Coconut oil is essential for its unique nutritional and economic purposes; which contain medium chain fatty acid and used for pharmaceutical purposes. The quality of coconut oil produced by the small-scale processors cannot be ascertained, as quality control measures and oil recovery cannot be strictly assured. The...
Abstract The effect of three different moisture and shade regimes on the seedling growth of three Dura x Pisifera oil palm progenies was investigated at the Oil Palm Research Institute, Kusi between July 1998 and February 2000. A split plot design with four replications was used. Data were collected on leaf number per plant, plant height, butt circumference and leaf area as well as dry weight of plant parts and total plant dry weight. Growth analysis was performed and correlation among traits...
ABSTRACT This study was conducted to identify some agronomic characters of maize plants which make them suitable for use in cassava/maize intercropping systems. The feasibility of intercropping cassava with high maize populations was also studied. A strip-split plot design with a parallel-row systematic arrangement in which five maize varieties, IK.84A-2135, IB84A-203 , TZSR-Y-1, 1368 x 5012 and 9450 x 4001 at five population densities of 10,000, 20,000, 40,000, 80,000 and 160.000 plants/ha i...
ABSTRACT Cassava is an important food security crop in Ghana and in the wake of climate change there is the need for plant breeders to develop varieties with high water use efficiency as well as high photosynthetic rate in order to adapt to the changing climate. Thus, the photosynthetic rates of eight cassava (Manihot esculenta Crantz) varieties were non-destructively evaluated using photosynthesis meter miniPPM300, from June 2014 to May 2015, with the aim of selecting varieties with high pho...
ABSTRACT Rice yellow mottle disease (RYMD), caused by Rice yellow mottle virus (RYMV), is a very damaging disease of rice in Sub-Saharan Africa. A participatory rural appraisal was conducted in Burkina Faso to assess farmers' awareness of rice production constraints with emphasis on rice yellow mottle disease (RYMD) and its management. RYMD was mentioned by farmers as the most important rice disease. Management practices included replacement of rice varieties and spray of pesticides. Farmers'...
