The performance evaluation was conducted using three cropstomatoes, pepper and okra which are loc...
ABSTRACT Simulation of complex hydrological responses in large watersheds over years has prompted the need for procedures for autocalibration. The commonly available models of watershed hydrology are of the event type applicable on a basin scale or continuous models applicable on a field scale. The Watershed Resources Management (WRM) model is a basin-scale model for continuous simulation. It is generally applicable in planning, forecasting and operational hydrology, to the study of environme...
ABSTRACTA study was undertaken to developed a model that will be used to predict sugar and theby-products from sugar cane. The model developed from MATLAB was used to predictthe sugar, bagasse, filter cake and molasses yield from sugar cane. The predicted valuesfrom the model were compared to yield data obtained from the production of sugar canefrom the Savannah Sugar Company, Numan, Nigeria for 90 days. The analysis ofvariance (ANOVA) at p ≤ 0.01 was used to determine if there were signifi...
Abstract Background: Changes of land cover modify the characteristics of habitat, host-vector interaction and consequently infection rates of disease causing agents. In this paper, we report variations in tsetse distribution patterns, abundance and infection rates in relation to habitat types and age in the Maasai Steppe of northern Tanzania. In Africa, Tsetse-transmitted trypanosomiasis negatively impacted human life where about 40 million people are at risk of contracting the disease with d...
Abstract The study was carried out to identify the entrepreneurial skills required by Internally Displaced Persons (IDPs) in quail production for sustainable living in North-Central Nigeria. Specifically, the study identified skills in planning, rearing and marketing of quail and its products in the area of study. To achieve these specific objectives, three research questions and three null hypotheses were formulated to guide the study. The study adopted descriptive survey research design. T...
ABSTRACT This work was designed to determine the ways of enhancing food production through organic agriculture among farmers. Five research questions and five null hypotheses guided the study. A survey research design was adopted for the study.The study was carried out in northern zone of Cross River State, Nigeria. The population for the study was 230 comprising 205 registered crop farmers and 25 Agricultural Development Programme (ADP) extension agents from Ogoja Agricultural Zone respecti...
Abstract The study was carried out to determine the effects of Moringa oleifera leaf powder additive on the growth of layers, egg production and nutritive value of eggs. Specifically, the study sought to determine among others the effects of Moringa oleifera leaf powder fortified feeds and control feed on the growth of layers, effects of different inclusion rates of Moringa oleifera leaf powder on the growth of layers, effects of Moringa oleifera leaf powder fortified feeds and control feed ...
Abstract This study was designed to determine the effects of field trip and land laboratory activities on students’ achievement and interest in poultry production in Senior Secondary Schools in Nsukka Local government Area, Enugu State. Six research questions were answered while six null hypotheses were tested at a 0.05 level of significance. The study adopted a quasi-experimental design and was carried out in Nsukka, Enugu State. The population of the study was 1,671 senior Secondary Sch...
Abstract The study was carried out to develop a training programme in cocoyam production for enhancing job opportunities of youth in South Eastern Nigeria. The study adopted research and development (R & D) design. The study was carried out in the South-East states of Nigeria, namely Abia, Anambra, Ebonyi, Enugu and Imo states. The population of the study was 5075 made up 21 lecturers, 292 extension agents and 4510 registered cocoyam farmers all from South-East Nigeria. The sample for the st...
ABSTRACT A biofiltration wastewater treatment pond was developed and the performance evaluation undertaken at the Department of Agricultural and Bioresources Engineering, University of Nigeria, Nsukka, southeast, Nigeria. The biofiltration wastewater treatment system is made of three compartments comprising a wastewater storage unit, wastewater treatment unit and treated wastewater compartment. The compartments are of the same size with the following dimensions 0.61m x0.61m x 0.5m having a ...
ABSTRACT Due to the scarcity of water in Nigeria, there is a need for an irrigation system that conserves water for efficient crop production. In the course of this research work, a drip irrigation system was constructed and tested with the sole aim of using cheaply available materials to determine the variation in emitter discharge at different heads and also, the coefficient of uniformity of the system. A test was carried out by determining the volume of water discharged by each of th...
ABSTRACT This thesis describes the in situ methods of the determination of both the hydraulic conductivity and infiltration capacity of the Federal University of Technology, Owerri (FUTO) farm soil. The inverse anger hole method was chosen to determine the hydraulic conductivity due to its simplicity and effectiveness. Cognizance was taken of the factors as presented in the project report that affect the results determined. Also the various methods of determining the two parameters...
ABSTRACT Before the exploitation of groundwater in a region, it is usually necessary to determine the hydraulic characteristics which allow the flow of water through aquifer and the amount of water that aquifer yields to well due to compression or dewatering of the aquifer. Hydrogeological work was carried out to characterize the aquifers of Afikpo-North L.G.A., Southeastern Nigeria. The study area lies within the lower Benue Trough of Nigeria and is underlain by Turonian Ezeaku Formation ...
ABSTRACT The effect of moisture content (5-24%) on some physical and compressive properties of the ‘Amelonado’ and ‘Hybrid’ varieties of cocoa beans were studied. Alongside, the effects of fermentation periods (0-8 days) on the biochemical profiles of the dried beans were studied in three morphological parts (whole bean, nib and shell). Four experiments were separately conducted as completely randomized, factorial designs. Compared to the ‘Amelonado’ variety, the axial dimensions ...
ABSTRACT Greenhouse is a feasible option for sustainable crop production in the regions of adverse climatic conditions. For a succe5sM greenhouse design, the selection of shape and orientation is of paramount importance. In this study, three most commonly used single span shapes of greenhouses namely even-spin, uneven-span and vinery type have be& selected for comparison. The length, width and height (at the center) are kept same for all the selected shapes. The relevance of this paper was t...
