ACCESS TO IMPROVED WATER SUPPLY FOR DOMESTIC USE IN OOTUNJA IKOLE LOCAL GOVERNMENT, EKITI STATE

ABSTRACTThis project is designed to determine households’ access to safe water supply in Ootunja, Ikole-Ekiti, in terms of quality and quantity as the importance of improved water supply to human health cannot be over emphasized. However, safe/improve water supply to most Nigerian cities is still inadequate. In the study area the relationship between water quality, the degree of water source protection and quantity. This aim was achieved through the use of well-structured questionnaire...

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

ABSTRACTThis 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 ...

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

ABSTRACTWater 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 tempe...

GEOTECHNICAL CLASSIFICATION AND CHARACTERIZATION OF SOILS IN FEDERAL UNIVERSITY OYE-EKITI IKOLE CAMPUS

ABSTRACTThis research project investigates the geotechnical characteristics of soils in Federal University Oye Ekiti, lkole campus. In this research project, disturbed soil samples were obtained from five labelled TP 1, TP 2, TP 3, TP 4, TP 5 at different locations and at various intervals along the university and were taken to laboratory for relevant soil engineering tests. The relevant soil tests include; particle size analysis, consistency limits (liquid, plastic, and shrinkage limits), na...

EVAPORATING COOLING SYSTEM

ABSTRACTAn 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 dr...

DEVELOPMENT OF SOLAR DRYER FOR FOOD PRESERVATION

 ABSTRACTA 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. T...

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

ABSTRACTThe 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 d...

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

 ABSTRACTMany 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 grasses...

DEVELOPMENT OF A DRIP IRRIGATION SYSTEM FOR A SMALL SCALE FARMING SYSTEM

ABSTRACTWater conservation and food security are some of the problems facing developing countries. The challenges of water conservation could be tackled by adopting the drip irrigation method. The drip irrigation system is an irrigation system that involves the artificial application of water to the base or root zone of plants in a controlled slow frequent and steady manner. This study was developed drip irrigation system for rural farmer on a small sale plot of an area of 7m X 5m with a...

DESIGN OF A COOLING SYSTEM FOR AN EXISTING FOOD EXTRUDER

 ABSTRACTFood extrusion is one of the earliest methods adopted by most industries to convert their paste raw material to a finished and desire shape based on their of an extrusion machine. Extrusion technique is a process in food processing technology that combines several unit operations including cooking. kneading. shearing. shaping and forming. The machine that forces the mix through the die is an extruder and the mix is known as extrudate. The extruder consists of large, rotating scr...

DESIGN OF A WEEDING MACHINE FOR AN UPLAND RICE FARM

 ABSTRACTWeed control is one of the most difficult tasks on an agricultural farm. Three methods of weed control are commonly known in agriculture. These are mechanical, chemical and biological control. Mechanical weed control is easily adopted by farmers once they get convinced of its advantages. Mechanical weed control not only uproots the weed between the crop rows but also keeps the soil surface loose, ensuring better soil aeration and water intake capacity. Weeding by mechanical devi...

DEVELOPMENT OF A SOLAR DRYER FOR A PROCESSED LOCUST BEAN

 ABSTRACTDrying is the oldest method of preserving agricultural products and it is an energy intensive process. High prices ·and shortages of fossil fuels have increased the emphasis on using alternative renewable energy resources. Drying of agricultural products using renewable energy such as solar energy is environmental friendly and has little environmental impact. Development of solar drying has brought a techniques and equipment for fast drying of various agricultura...

Effects of blast furnace slag on chloride permeability of concrete cured at elevated temperatures

ABSTRACTConcrete made from ordinary Portland cement continues to be used as the main construction materials because of its durability and strength characteristics in service life. But the contrary becomes the case when such concrete is exposed to aggressive environment created by the prevalence of chloride ions that are common in marine/coastal environment characterized by temperature extremes, that is peculiar to Nigeria. Hot marine and coastal environment, constitute an aggressive environme...

Environmental Benefits of the Structural Use of Pulverised Bone in the Production of Foamed Aerated Concrete

AbstractDisposal of wastes resulting from myriads of human activities continues to be a problem especially in developing nations, where effective and efficient wastes disposal system is lacking. This paper presents the result of the study conducted to investigate the environmental benefits of using pulverized bone - obtained from bones generated as waste from abattoirs and slaughter slabs - in the production of structural foamed aerated concrete. Some of the properties investigated into are c...
