ABSTRACT In a study at KNUST weather station, the crop co-efficient values at initial, development, mid-season, and late season stages of ABONTEM MAIZE (hybrid variety) were determined as 0.42, 0.98, 1.05, and 0.32, respectively. These locally determined values of ABONTEM hybrid maize compared favourably with those recommended by FAO. The corresponding FAO values are 0.4, 0.80, 1.15, and 0.70. The FAO values are average values and recommended for a wide range of locations, but those dete...
ABSTRACT The consumptive use of water assures all year round production of groundnut prone to the vagaries of weather and climate. This brought about the need to supply moisture that is naturally available through rainfall. The successful design of any irrigation system requires the knowledge of the consumptive use of water by the crop under consideration. This need led to the investigation of the water use rate of groundnut in a typical area found in Awha-Imezi of Ezeagu in Enugu State ...
ABSTRACT The motorized cassava peeling machine is a type of cassava peeling method that is adopted to reduce drudgery. In cassava peeling operations. This method, unlike the manual peeling method which consumes a lot of human power with subsequent low output produces or peels a large amount of cassava tubers within a small specific of time and small amount of flesh loss and finally low demand of power. this paper presents the design and constructing of a motorized cassava peeling machine th...
ABSTRACT A comparative study was conducted among organic waste materials namely coconut fiber, hair, sawdust and woodchips as crude oil absorbents. Twenty grams of each of these materials were wrapped in a pouch and submerged into two set-ups, Set-up A: Pure Crude Oil and Set-up B: Crude Oil with seawater, for an hour. Amount of oil absorbed was gathered and recorded. ANOVA was conducted to verify if the results significantly differed. The results show that hair had the highest amount of ab...
ABSTRACT Flooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth of flooding on the survival and growth of rice. Data showed that time and depth of flooding had significant effects on the survival and growth of ric...
ABSTRACT The microbiological and organic pollutants characteristics of umuosoko stream in ikwuano local government area, Enugu state, Nigeria were carried out. Twenty water samples were collected from four different parts of the river. The pour plate technique was employed for the isolation of micro-organisms. Colonial morphology, Gram staining and biochemical tests were used for identification and characterization. The statistical analyses used were analysis of variance and standard devia...
The study aimed at the design, construction and performance evaluation of a model domestic wastewater treatment plant was carried out. The treatment unit was a Waste Stabilization Pond (WSP) comprised of one facultative pond, three maturation ponds, and a contact filtration unit, all in series. The effluent of the WSP, after filtration through clay media, had the BOD reduced to 15.4mg/l, from 356mg/L indicating a 95.67% removal level. A Faecal Coliform (FC) count of the influent sample gave 1...
