ABSTRACT Two field experiments were carried out from July 1993 to January 1994 at the University of Ghana farm, Legon. The first experiment investigated the effects of two preemergent herbicides alachlor-atrazine mixture and diuron at the manufacturers' recommended rates and at rates 50% above those recommended on weed control, growth and yield of maize variety 'Abeleehi'. The second experiment carried out on the same plots determined the residual effects of these herbicides on two varieties...
ABSTRACT The intestinal microbiota is known to affect their host either beneficially or harmfully. Efforts have, therefore, been put into identifying and studying the microbial community in the gastrointestinal tract of livestock. Grasscutter is a promising micro livestock species with a short history of domestication, whose intestinal microflora is yet to be explored. Among the intestinal microflora, lactic acid bacteria confer probiotic benefits and are thus of special interest. This study ...
ABSTRACT A survey was conducted in 1994 to gather information on the practice of intercropping food crops in oil palm on small-scale farms in the oil palm zones of southern Ghana. The objective was to identify and study intercropping systems used in oil palm production. Data was collected by interviewing a total of 72 oil palm farmers from the oil palm growingregions,(Eastern, Central,Western,Ashanti,Brong-Ahafo,and Volta) at their farm locations. The responses indicated that the small-scale...
ABSTRACT Fonio (Digitaria spp) is a neglected and underutilised crop traditionally grown in the Sahelian savannah agro-ecological zone of Ghana for its grain which is rich in crude protein, fibre and has medicinal properties. Decline in production of the crop is attributed to poor agronomic and yield characteristics and changing agro-climatic conditions as a result of global warming which has rendered traditional growing areas too dry to support cultivation of the crop. There is a need to ex...
ABSTRACT ASSUMING-BREMPONG, SAMUEL, University of the Philippines at Los Banos (UPLB), October 1987. COMPARATIVE ADVANTAGE AND RICE POLICY IN GHANA. Major Professor: Dr John C. Flinn. Even though rice is a minor staple in Ghana (WARDA estimated per capita consumption to be 6.7 kg. in 1983), and accounts for about 1 0% of all cereals, its imports to the country have been second only to wheat which is not grown domestically. Successive governments in Ghana have therefore declared an objective ...
ABSTRACT The Hipposideros caffer complex consists of several taxa whose taxonomic relationships are not fully resolved. Genetic diversity and skull morphology of Ghanaian populations of the Noack’s leaf-nosed bat Hipposideros aff. ruber (Noack, 1893) attributed to mitochondrial D lineages were investigated using nucleotide sequences of mitochondrial cytochrome b gene and geometric morphometrics. Cytb sequences of H. aff. ruber populations from Ghana were compared to other available West Af...
ABSTRACT A study was carried out at the University of Ghana from January 2001 to January 2002 to find out if Labreko and Pona yam varieties treated exogenously with some growth regulators will respond to yam minisett technique. Six experiments were set up consisting of three yam minisett sprouting studies and three field assessments of the sprouted mini setts The objective of the study was to use growth regulators to enhance sprouting of Labreko and Pona minisetts and to improve field perfo...
ABSTRACT Variation in some growth and y ie ld characteristics were studied in 16 lo ca l and exotic cowpea varieties grown in the country. ELanting was done at three different times of the year representing three seasons. The characters studied were: days to 8C$S germination, days to 5 flowering, average dxy weight per plant at 5
ABSTRACT The study was conducted in three landing villages along the coast of Greater Accra Region of Ghana, namely; Ada, La and Bortianor from November 2018 to April 2019. The purpose of the study was to assess the abundance of jellyfish in beach seine landings. Biological data was obtained primarily from local fishermen who deployed beach seine net. The jellyfish families that were encountered were four in number and a total of 2,676 individuals from 72 beach seine hauls. These were; Catost...
ABSTRACT Sorghum is the second most important cereal crop after pearl millet in terms of area planted, production, and per capita consumption in Mali. Production of sorghum is declining due to several reasons including lack of sorghum hybrids and adapted varieties tolerant to drought. Evaluation of sorghum genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. The general objective of the study was ...
ABSTRACT Striga hermonthica (Del.) and low soil nitrogen (low N) are among the most important constraints to maize production and productivity in West Africa (WA). Knowledge and understanding of the inheritance of Striga resistance and low N tolerance in early maturing maize inbreds are invaluable in developing hybrids adapted to both low N and Striga-infested environments in WA. The objectives of the present study were to (i) assess the genetic diversity among the inbred lines using simple s...
Abstract Although IPM has been advocated as a means of reducing chemical insecticide application, adoption of IPM practices are however, inadequate in the Hohoe Municipality and this may be attributed to a number of socio-economic and institutional factors. The study therefore sought to determine the knowledge levels and use of IPM practices by rice farmers. Survey research design was used for the study. Multi-stage sampling procedure was used to select 120 rice farmers. Both descriptive and ...
ABSTRACT This study was conducted to assess the growth, nodulation and nitrogen fixing potential of some native multipurpose trees and shrubs. A total of fourteen species of indigenous leguminous trees and shrubs were initially screened for nodulation in three Ghanaian soils (Toje, Hatso and Alajo soil series), after 8 weeks of growth in nursery bags. The experiment was repeated with nine species of the tree/shrub legumes, this time under two levels of phosphorus (0 and 60 mg P/kg soil). The ...
ABSTRACT The effects of three maize varieties and two storage seasons on the population dynamics of Prostephanus truncatus and Sitophilus zeamais were observed in the traditional4Ewe’ barn on the field. Two local varieties, Dzolokpuita and Abutia and an improved variety, Abeleehi, were stored with the husk on, during the long season, and Abutia only during the short season, of the 1994/1995 storage period. Destructive sampling techniques were applied to obtain data at monthly intervals for...
ABSTRACT The study set out to identify agglomeration externalities in Ghana’s soybean sector and to assess soybean output elasticities with respect to input-use. The study also analyzed the technical efficiency levels in the soybean sector and the effect of agglomeration externalities on productivity and technical efficiency of soybean farms. The study identifies some components of agglomeration externalities across the soybean sector and defines agglomeration externalities by two indexes;...
