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...
ABSTRACT Pelleting materials and soil amendments have the ability to enhance nitrogen fixation through improved nodulation in leguminous species. Pot and field experiments were conducted in the Sinna Garden, Department of Crop Science, and University Farm, University of Ghana, Legon, during the 2018 minor and 2019 major rainy seasons respectively, to access the effect of seed pelleting with different materials and different soil amendments on nodulation, growth and yield of soybean (Glycine m...
ABSTRACT Demand for rice from developing countries is steadily increasing, replacing most of the coarse grains and root crops as the major source of dietary calories. Food insecurity in many Africa countries is inevitable if efficient procedures for boosting productivity, decreasing cost of production, and protecting the environment are not taken into account. The per capita consumption of rice in Ghana is currently about 24 kg per annum. Consumption of rice will continuing to go up due to ra...
SUMMARY The microsett technique involves the use of 2-10g setts comprising two size-ranges: a lower 2-5g and an upper 5. Ol-lOg. Preliminary experiments were undertaken to determine the ideal presprouting medium, moisture regime of the latter, presprouting environment, and sett size of the microsetts derived from the white yam variety, TDr 131. The upper 5.01-10g sett-class presprouted in open-air, raised beds covered with low palm-frond shade, using fresh sawdust at an initial moisture cont...
ABSTRACT Bacterial wilt of tomato is a devastating disease in greenhouse in southern Ghana where most greenhouses are sited. This study was conducted to assess farmer’s knowledge and experiences on the prevalence, detection, spread and control of the disease in greenhouses in Volta, Eastern, Central and Greater Accra regions of Ghana. The disease incidence and severity was also determined and the causal organism of the disease isolated from diseased tissues and characterized using morpholo...
ABSTRACT Globally, rice (Oryza sativa L.) is the third largest cultivated cereal crop with about 79 million hectares of irrigated lowlands providing 75% of the world’s rice production. Its productivity depends on many factors including Nitrogen (N) fertilizer and water management. This study was conducted to determine the effect of water management and N fertilizer on growth and yield of rice. The study also sought to evaluate the cost effectiveness of water use under various water managem...
ABSTRACT Two field experiments and a laboratory experiment were conducted at the University of Ghana, Farm, Legon and the Department of Crop Science respectively between June 2012 and May 2013 to determine the variation in floral morphology, fruit set and seed quality of twelve garden egg accessions. A randomized complete block design was used for the field experiments while a completely randomized design was used for the laboratory experiment. Data were collected on vegetative, reproductive...
