Design, Fabrication and Performance Evaluation of Pedal Operated Groundnut Decorticator

ABSTRACT Shelling of groundnut pods (Arachis hypegea) by hand is tedious, laborious and unhygienic with low efficiencies. As a result farmer get low income due to amount of broken kernels and a lot of time is lost in the tedious shelling operation. To overcome this problem, pertinent parameters that influence shelling efficiency of pedal operated groundnut decorticator were identified. Pedal operated decorticator were designed and fabricated with chain and sprocket of bicycle and aluminum spi...

Development and Fabrication and Performance Evaluation of a Single Wheel Driven Boom Sprayer

ABSTRACT The single wheel driven boom sprayer was developed, fabricated and evaluated for its performance at the department of Agricultural and Bio-environmental engineering workshop, Kwara state polytechnic, Ilorin. The spraying performance was carried out at spraying height of 0.5m, 0.6m and 0.7m respectively. The theoretical  field capacity CT, the effective field capacity CE and  Field efficiency (ŋ) at spraying height of 0.5m  are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying h...

Prediction Of Runoff And Sediment Yield From Agricultural Watersheds Using Annagnps: A Case Study Of Upper Ebonyi River Watershed, Enugu State.

Abstract Sediments resulting from soil erosion are the major non-point source pollutant of surface waters in agricultural watersheds. Annualized Agricultural Non-Point Source Pollution Model (AnnAGNPS) is a computer-based watershed model that predicts non-point source pollutants and runoff loadings within agricultural watersheds. AnnAGNPS v5.2 was used in conjunction with Arcview 3.2 GIS to predict streamflow and sediment discharges from a 250.89 ha agricultural watershed, Upper Ebonyi River...

Design and Construction of an in-situ salinometer for agricultural soils

The increase of salinity in soil and water bodies which simultaneously declines the productivity of agriculture is of great concern to the Nigerian Federation which holds agriculture as a major means of survival for its economy. Thus, the proper monitoring,use and management of soil and water bodies is a sure way to proffer solutions to food shortage and poor crop yields. This can however be achieved by the use of a fast, reliable, and accurate in-situ salinometer. A portable in-situ salinome...

Evaluation of The Effect of ANTHROPOGENIC Activities and Domestic Waste On Surface Water

ABSTRACT  The microbiological and organic pollutants characteristics of Owena dam in Ifedore local  government  area  of  Ondo-state,  Nigeria  was  carried  out,  nine  water  samples  were collected from three different parts of the downstream side, which include; around the waste disposal  site,  community  settlement  and  farm  environment.  The  microorganisms  isolated were  escherichia  coli,  enterobacter  species,  staphylococcus  aureus,  proteus  spec...

DESIGN OF A LOW COST MAIZE SHELLER

ABSTRACT Maize, known in many English-speaking countries as corn, is a grain domesticated by indigenous people in prehistoric times. The Aztecs and Mayans cultivated it in numerous varieties throughout central and southern Mexico, to cook or grind in a process called nixtamalization. The crop spread throughout America and later around the 1250 BC it spread to all corners of the region. Any significant or dense populations in the region developed a great trade network based on surplus and var...

Effect of Electromagnetic Treatment of Water on Growth, Germination and Yield of Maize Crop

The effect of magnetic treatment of water on the growth, yield and germination of maize seed has a positive impact in Agricultural crop production

DESIGN, CONSTRUCTION AND TESTING OF AN EVAPORATIVE COOLING FACILITY FOR STORING VEGETABLES

ABSTRACT A 1.05 cubic metre capacity storage facility which is to increase the shelf life of stored vegetables as designed fabricated and tested. The equipment operates on the principle of evaporative cooling and increasing the relative humidity of the interior of the equipment. The door and the back wall were of particle board of 12mm thickness while the two sides are made of jute bag through which water flows on a trough at the top flows with the influence of gravity. The facility designed...

EFFECTS OF SOIL PROPERTIES ON ERODIBILITY AND INFILTRATION: A CASE STUDY OF UNAAB HOSTEL

ABSTRACT Erodibility of UNAAB soil series for nine plots behind the female hostel ( i.e. plot A – I) using regression equation were determined by evaluating first organic matter content, using the Walky Blanks method, the particle size analysis, permeability test, bulk density and chemical properties of the soil such as Sodium, Cation Exchange Capacity, acidity, Potassium, Magnessium and calcium. The organic matter content of the soil(Ibadan series-sandy loam) was found to be;plot1 d...

MODIFICATION OF A COCONUT OIL EXTRACTOR

ABSTRACT A prototype of hydraulically operated coconut oil extractor was designed and fabricated. The machine can be used for other oil-bearing seeds such as groundnut and palm kernel. The machine is made up of a plunger, ram disc, expression chamber, and electric heater. The extractor can process 10kg coconut per hour. An efficiency of 15% was obtained from the coconut cake of 2.9kg (wet basis). While for the dry basis 40% of oil was obtained from coconut cake of 2.5kg. TABLE OF CONTENT TI...

THE INFLUENCE OF RAINFALL DURATION ON SPLASH PRODUCED FROM A LOAMY SAND SOIL

ABSTRACT At the event of soil erosion, rain splash erosion supplies materials for subsequent transportation and entrainment. The influence of rainfall duration on splash produced from a loamy sand soil in Camp area of Abeokuta, Ogun State was studied in the laboratory using a laboratory rainfall simulator. The study area is always subject to serious erosion. The objectives of the study are to analyze the characteristics of splash erosion on the soil due to different rainfall duration at diff...

THERMAL CONVERSION OF PALM KERNEL SHELL AND MESOCARP FRUIT FIBRE INTO FUEL

ABSTRACT Palm Oil processing yield a considerable quantity of palm kernel shell (PKS) and mesocarp fruit fiber (MFF). This has been predominantly used as fuel through direct combustion which is inefficient and polluting. Better grade fuel could be derived through torrefaction. The objectives of the work therefore was to determine the optimum parameters for the conversion of palm kernel shell (PKS) and mesocarp fruit fiber (MFF) to high grade fuel via torrefaction. Samples of PKS and MFF were...

DETERMINATION OF CROP COEFFICIENT OF A VARIETY OF MAIZE(ABONTEM MAIZE)

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...

DESIGN OF AN ORANGE COLLECTOR

Equipment development in Ghana to harvest oranges have over the years focused on simple units such as Garden tool, basket style picker etc. and common methods of harvesting oranges in Ghana are the use of manual branch shaking, manual pull with the hook stick. The effects leads to:Infestation of a bacteria called Alicyclobacillus when the fruits fall on the ground.The bacteria lives on the fruit which contaminates it.Bruises through impact on the hard surface.The main aim of this study is to ...
