Development and Performance Evaluation of a Double-Rotor Self-Action Cassava Grater

ABSTRACT The modification of a single-rotor cassava grater was undertaken. The singlerotor grater was modified into a double-rotor self-action grater and its performances evaluated by determining its throughput capacity and efficiency. The throughput capacity was determined by grating known quantities of cassava roots in three respective runs and the time taken to grate them measured from a stop watch. The efficiency of the machine was calculated from the quantity of roots grated and quantit...

Bioremediation of Hydrocarbon Contaminated Soil using Selected Organic Wastes

ABSTRACT Contamination of existing and potential agricultural lands is a major problem associated with the processing and distribution of crude and refined petroleum products in many oil producing countries like Nigeria. Hydrocarbon contaminants in soil are potentially phytotoxic to plants and interfere with plant establishment and growth as well as other land uses. The problems of pollution have led to the exploration of many remedial approaches to effect the clean-up of the polluted soils....

Use of the Swat Model to Evaluate the Impact of Land-Use Change on Ebonyi River Watershed

ABSTRACT SWAT was applied a large watershed (3,765km2 ) in south-eastern Nigeria, to predict streamflow and sediment discharge from the Ebonyi River Watershed using globally available data downloaded from the internet. Digital elevation, land-use and soil maps of the study area from global databases and historical weather data measured locally were used. SWAT model was setup to use the MapWindow GIS interface. The model predicted an average daily streamflow and sediment discharge of 24.32m3 ...

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...

Effect of Moringa Oleifera Leaf Powder Additive on The Growth of Layers, Egg Production And Nutritive Value of Eggs in Agricultural Education Farms

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 ...

Development of A Training Program in Cocoyam Production For Enhancing Job Opportunities For Youths in South East Nigeria

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...

Development of Biofiltration Wastewater Stabilization Pond For Agricultural Purposes

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 ...

Design, Construction And Testing of Drip Irrigation System Using Medical Drip as Emitter

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...

A SURVEY OF THE TECHNIQUES AND TECHNOLOGIES FOR CASSAVA PROCESSING IN EKITI STATE

ABSTRACT This study was carried out to examine the techniques and technologies for cassava processing in Eliki Slate, to identify the various products from cassava in the study area, to generate ways of improving the techniques and technologies, and to recognize the constraints to processing and marketing of cassava products. The study made use of structured questionnaires, oral interviews and focused group discussions to select a sample size of 120 respondents.The population under study was...

THE PHYSICAL, CHEMICAL AND BIOLOGICAL ANALYSIS OF FISH POND WASTE WATER: A CASE STUDY OF ABUAD FARM, ADO-EKITI, EKITI STATE NIGERIA

ABSTRACT Water released from ponds has greater concentrations of nutrients, organic matter and suspended solids. This study investigated the physical, chemical and biological characteristics of fish pond waste water harvested from a source which served as the control, three different ponds and at the point of discharge in Afe Babalola University Ado Ekiti (ABUAD) farm, Ekiti State. The samples were collected in 50 ml capacity polypropylene containers. Parameters investigated include temperat...

EVAPORATING COOLING SYSTEM

ABSTRACT An evaporative cooling system was designed, fabricated and tested for the storage of fresh fruits and vegetables. The system's working principles is based on the principle of evaporation which causes a cooling effect to its surrounding. The system is an enclosed system and air is allowed to pass only through the pad, also a suction fan centrally located which draws in air through the pad. Water drips into the foam at a constant rate through a water distribution system. As the water d...

DEVELOPMENT OF SOLAR DRYER FOR FOOD PRESERVATION

 ABSTRACT A solar dryer integrated with a simple bed rock was designed and constructed with locally available materials to dry tomatoes and pepper. The dryer was composed of solar collector, drying chamber, back up heater and airflow system all integrated together. The back-up heater provided alternative heating during cloudy weather conditions or at night when solar radiations were low. The dryer was designed based on climatic conditions of Ikale summit located in Ikale, Ekiti Nigeria. The ...

STUDY OF SOIL ORGANC CARBON AND LAND USE IN FEDERAL UNIVERSITY OYE-EKITI, IKOLE CAMPUS, EKITI STATE NIGERIA

ABSTRACT The amount of soil organic carbon (SOC) stored in a particular soil is influenced by several factors including climate, vegetation type and age, land management, soil properties and current and past land use. The impacts of land use types on soil organic carbon were assessed. Four land use types were used in the study. Sampled soils were taken at depth of 0-45 cm and at intervals of 15 cm. The soil samples were examined in accordance with the standard methods. The data were analy...

Growth Rate and Biomass Accumulation of Forage Sorghum (Sorghum almum), Congo grass (Brachiaria ruziziensis) and Rhodes grass (Chloris gayana)

 ABSTRACT Many grasses have played prominent roles in forage research and livestock production in Nigeria. Grasses possess two main photosynthetic pathways: the C3 pathway that is typical of most plants and a specialized C4 pathway that minimizes photorespiration and thus increases photosynthetic performance in high-temperature and/ or low- CO2 environments. Rhodes grass (Chloris gayana) is a perennial grass of tropical and subtropical Africa where it remained one of the main C4 forage grass...
