The greenhouse technology is a booming segment of agriculture in the world, because it offers a favorable climate conditions which increase plants growth as the plants are grown in a controlled environment. This research assessed the present conditions of the Controlled Environment Agriculture (CEA) in Ghana and emphasized on issues that are paramount to Greenhouse vegetable production effectiveness. The general objective was to evaluate the current status for greenhouses in Ghana and p...
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...
Two field experiments were carried out at W eija Irrigation Company (Ghana), from February to November 1995 on the effective use of Bacillus thuringiensis Berliner subsp. kurstaki (Dipel 2X) against the diamondback moth Plutella xylostella on cabbage (Brassica oleraceu var. capitata (L.). In the first experiment, different concentrations (0.25 g/1, 0.5 g/1, 1.0 g/1 and 2.0 g/1) of Bacillus thuringiensis subsp. kurstaki (B.t.) were applied at weekly and fortnightly intervals on cabbage p...
The genetic control of resistance to the cassava mosaic disease (CMD) in some African landraces, their relationship with the widely used resistant genetic stock, clone 58308, and molecular markers associated with resistance to CMD in the landraces were evaluated in this study. The F-i progenies of 54 cassava crosses and their parents (clone 58308, six improved clones and 15 African landraces) were evaluated in two genetic experiments in three environments in Nigeria. Genetic analysis re...
ABSTRACT Green (fresh) maize (Zea mays L.) provides food security and income to farmers especially when other crops are still in the field. However, research on green maize variety is scarcely reported in literature or information on suitable genetic material (germplasm) for green maize production. Developing maize for fresh maize production in the southeastern Nigeria was carried out in the Center for Agricultural Research, School of Agriculture and Agricultural Technology, Federal Univ...
ABSTRACT A pot experiment was carried out from 15th December, 2014 to 20th June, 2015 at the University of Ghana Forest and Horticultural Crop Research Centre (FOHCREC), Okumaning under greenhouse conditions in a randomized complete block design to investigate the influence of grafting on growth, yield, quality and shelf life of tomato grafted onto three solanum species. Two tomato varieties ‘Fadeεbege’, and ‘Nkansah HT’ were used as scions and three solanum specie ‘Gboma’, ‘Bl...
ABSTRACT Plantain (Musa spp) is one of the most important food crops. A limiting factor to large-scale production and or expansion of existing plantation is the difficulty in obtaining adequate planting materials. Although the tissue culture technique provides a higher multiplication rate, facilities are non-existent, and if available, the cost will be expensive and unavailable to most farmers in developing countries such as Ghana. The split-corm technique is a cheaper method for raising plan...
ABSTRACT Laboratory and field experiments were carried out between June 1997 and Januaiy 1999 at Paradise farm near Nsawam in the Eastern Region of Ghana to determine the major insect pests of papaya, Carica papaya and to evaluate the effectiveness of Bacillus thuringiensis and neem seed extract for controlling the insect pests of papaya. Methanolic and aqueous neem seed extracts were tested at the following concentrations 0 , 50, 75 and 100 g/1. Bacillus thuringiensis was applied at the rate...
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)...
