ABSTRACT Cancer incidences are on the rise in Namibia, because of late diagnosis, cancer cases often have poor prognosis and treatment options are limited especially in resource poor rural settings. Ethnomedicinal plants present a treatment option which is used in such settings, is accessible and inexpensive. However evidence on safety and efficacy of these traditional medicinal plants is lacking, which prevents mainstream use. This study evaluated two Namibian indigenous plants, Schinzioph...
ABSTRACT Aphid infestation is recognized as one of the major constraints that limit cowpea production in Africa. Host-plant resistance has proven to be the most efficient and sustainable means to controlling aphid infestation and its associated challenges. The objectives of this project were to characterize cowpea varieties using 38 agro-morphological and 20 SSR markers, and also to deploy aphid resistant locus into three locally preferred aphid susceptible cowpea cultivars. A total of 22 cow...
ABSTRACT In the present study, a total of twenty (20) tomato genotypes were evaluated simultaneously under greenhouse and field conditions in order to determine genetic variability present in the agronomic and fruit quality traits. The experiments were laid out in a Randomized Complete Block Design (RCBD) with three (3) replications. Both individual and combined analyses of variance were employed. The individual analysis of variance showed a significant (P < 0.01) variability among the genoty...
ABSTRACT Tomato is one of the most important vegetable crops cultivated in Ghana and constitutes part of the daily diet of most of the populace. Ghana produces 366,772t/ha annually, yet imports 25,000t/ha of tomato paste and $9.9million worth of fresh tomatoes from Burkina Faso and Europe annually to fill the supply gap which puts a lot of pressure on the country’s GDP. To help minimize importation and bridge the demand gap, several interventions have been proposed including greenhouse prod...
ABSTRACT Striga hermonthica (Del.) Benth infests millions of hectares of land under cereals in sub-Saharan Africa, reducing production and threatening food security. A field experiment was carried out at the Savanna Agricultural Research Institute (SARI) trial farms at Nyankpala. The trial was to determine the combination of maize varieties, ammonium sulphate and chicken manure that could enhance the performance of maize in infested Striga field. In addition, the effect of treatments on the ...
ABSTRACT Mango bacterial black spot disease is one of the most devastating diseases of mangoes worldwide. The disease was observed in some mango orchards in the Lower Manya and Asuogyaman districts of the Eastern region and North Tongu district of the Volta region of Ghana. The objectives of this study were to assess farmer’s perception and knowledge on the prevalence, spread and economic importance of the mango bacterial black spot disease, determine the disease incidence and severity in m...
ABSTRACT Cassava (Manihot esculenta, Crantz) is primarily grown for its starch containing tuberous roots, which are a major source of dietary energy in the tropics. It is highly perishable and begins to degenerate shortly after harvest. Cassava in the fresh form contains cyanide, which is extremely toxic to humans and animals. These factors make the processing of cassava into a dry form a necessity. Processing is essential for the removal of cyanides from cassava roots. This post-harvest nece...
ABSTRACT Three experiments were conducted to evaluate cassava, a tropical root crop, as a source of energy in diets containing all vegetable protein or 5% fish meal which is a source of readily available essential amino acids required by growing chicks. The biological metabolizable energy (ME) was determined replacing part of the basal diet with the test materials (cassava meal Grades I and II combined and Grade III. Grades I and II have little of the rind and outer cover whereas Grade III co...
SUMMARY Two field experiment where conducted to evaluate the performance of 142 prodigenes
ABSTRACT Two field studies were carried out from July 2012 to February 2013 to determine the efficacy of four groups of herbicide on weed control, growth and yield of maize (Zea mays L.) and to investigate the influence of their residual effect on weed succession, rotation crop, soil nutrient status and microbial population at the University Farm, Legon. The experiments, laid out in randomized complete block design, consisted of four replications of eight herbicide treatments from four herb...

Abstract Forty-five cowpea accessions, randomly selected from cowpea germplasm from four cowpea-growing regions of Ghana, namely, Upper East, Upper West, Northern and Eastern Regions, were characterized and evaluated at the Plant Genetic Resources Unit of the Crops Research Institute at Bunso with the objective to determine the range of variability in the samples with respect to vegetative, inflorescence and fruit characters. The variability in the samples was used to initiate hybridization...
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 was evaluated in this study using two cultivars - Sauti and Okumkom released to farmers by the Crops Research Institute. The study was aimed at developing technology to ensure the availability of adequate quantities o...
ABSTRACT Studies were undertaken to identify the pathogens associated with rotting of white yam (.Dioscorea rotundata var. Araba, Asana and Puna) in Ghana, to identify exportable white yam varieties with superior shelf life and to evaluate the effectiveness of lime and neem wood-ash in controlling rots in wounded yam tubers. A field survey was conducted among yam retailers and exporters in Accra. The results revealed that: a major constraint to yam production and marketing in Ghana is the hig...
ABSTRACT The mycoflora of two recently-developed maize (Zea mays L) varieties Abeleehi and Obaatanpa have been studied under varying ambient equilibrium relative humidities E R H ’s (55, 60, 65, 70, 75, 80, 85, 90 and 95%) representative of the Ghanaian ambient conditions. The potential pathogenicity of selected contaminating fungal species (A. alutaceus, = A. ochraceus, Fusarium, moniliforme, Penicillium digitatum, Peacilomyces carneus, P. puntoni and P. varioti) was also tested under labo...
