A B S T R A C T In a diallel cross involving six kola trees, two from each of the cultivars Laboshie white ex Nigeria, Kumasi white and Kade pink, a self compatible tree of the Kade pink cultivar was found to be the most efficient female but the least efficient male parent for fruit set. The frequency of red, white and pink nuts that segregated in the progeny of the various crosses suggests that a single locus with multiple alleles controls the inheritance of kolanut colour. At physiological ...
ABSTRACT The sustenance and progress of any breeding program and conservation of its germplasm is hinged on the ability to estimate the degree of genetic diversity in a given gene pool for maintaining crop production. Therefore, data on the genetic diversity and relationships among plant genotypes is vital to identifying the complexity of the gene pool, to ascertain breaches in genotype collections in order to develop effective conservation and management strategies. This study was conducted ...
ABSTRACT The study was conducted in two phases. Phase 1 was to assess the handling and management of watermelon along the value chain in the Ada-East district of Ghana. One hundred open and close ended questionnaires were administered to farmers and dealers of watermelon. From the study, it was observed that the value chain of watermelon starts from land preparation and ends at the point it gets to the final consumer. The key players along the chain were identified to be farmers, dealers (tra...
ABSTRACT An experiment was conducted at the Forest and Horticultural Crops Research Centre, Kade to investigate the effect of palm bunch ash (PBA) application on soil chemical properties and the growth, nodulation, nitrogen fixation and yield of three early maturing varieties (ICPL 87091, ICPL 88034 and ICPL 88039) of pigeonpea. The experiment was conducted both in the field and in the pot. The three pigeonpea varieties were subjected to three fertilization treatments; 2 t ha–1 PBA, 20 kg h...
ABSTRACT The rapid population increase and land scarcity calls for an alternative means of production system for sustenance of the human race. This prompted an investigation into the growth, yield and consumer acceptance of sweet pepper (Capsicum anuum L) as influenced by open field and greenhouse production systems at the University of Ghana Forest and Horticultural Crops Research Centre, Okumaning – Kade in the Eastern Region of Ghana. The experiment was conducted in the minor season (dr...
ABSTRACT Ghana's Horticultural sector over recent years has seen tremendous growth and development with increasing demand for tropical fruits in Europe and the rest of the world. With the rise in competition among producing countries, it has become very important for the sector to be strengthened. Demand for quality produce by consumers in these developed countries has been a challenge to producers from developing countries like Ghana. For Ghana to compete favourably among its peers in the gl...
ABSTRACT A series of studies were carried out in the Greater Accra region from October, 2012 to May, 2013 to ascertain agro-input usage in okra production and its effects on quality of production and the produce. Studies comprised a survey, two field studies (an on–farm trial and a field experiment) and one laboratory study. For the survey, data were collected through the administration of questionnaires and analyzed using Statistical Package for Social Sciences (SPSS) software (version 18)...
ABSTRACT A study was carried out in 2012 in a Sudan savanna ecology in Ghana aimed at identifying the optimal planting dates and suitable cowpea varieties for green pod production. Six planting dates were considered starting from the onset of the rainy season (20th June, 30th June, 12th July, 25th July, 2nd August and 12th August), and four improved cowpea varieties released by Savanna Agricultural Research Institute (SARI) of the Council for Scientific and Industrial Research (CSIR) as Baaw...
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 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 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 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 Cucumber (Cucumis sativus L.) is an edible crop produced in Ghana for both the local and export markets. The perishable nature of the fruit results in huge postharvest losses. The use of edible coatings to preserve commodities is inexpensive, easy to apply, requires less labour, technology and improves fruit qualities. However usage of this technology has raised some concerns with major stakeholders of the fruits and vegetables industry regarding health, safety, availability and cost...
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 trait...
