Evaluation Of The Technical Performance Of A Low Cost Drip Irrigation System For Smallholder Farmers

ABSTRACT It is essential that smallholder farmers in developing countries have access to the benefits that modern irrigation technology seeks to offer. However, this has not always been so because of the inability of smallholder farmers in developing countries to adopt this advanced technology due to cost constraints. The objectives of this study were to design and construct a simple low cost drip irrigation system suitable for smallholder farmers, and to evaluate the technical performance ch...

Development And Performance Evaluation Of A Non-Weighing Lysimeter For African Spinach

ABSTRACT    A non-weighing lysimeter was designed, fabricated, tested and installed at Arochukwu, Abia State, Nigeria, where the farmers who engage in dry season vegetable production do so with no knowledge of irrigation water requirements. This method tends to either over-irrigation or under-irrigation below the vegetable water requirements. Too much water can leach costly fertilizers to depths below the root zone, where both the water and fertilizer are permanently lost. Too little water ...

Development And Evaluation Of An Integral Passive Solar Crop Dryer

ABSTRACT    A direct-heated solar crop dryer suitable for rural farmers and households was developed and evaluated. The simple structured dryer was fabricated using square and round pipes, aluminium sheet, Perspex, wire gauze, bolts and nuts. Its performance was evaluated using cassava chips and three cylindrical aluminium chimneys of heights 1200mm, 800mm and 400mm; all of equal diameter. Mature cassava roots were peeled, washed, chopped into flat circular chips of 10mm thickness and sprea...

Determination Of The Compressive Strength Of Palm Kernel Shell Concrete

ABSTRACT  This study is on the determination of the Compressive Strength of Palm Kernel Shell Concrete. The effect of percentage replacements (0, 25, 50, 75 and 100%) of crushed granite with palm kernel shell on density and compressive strength of concrete is presented. Concrete cube specimens of mix 1:2:4 were prepared with water-cement ratio of 0.6. The cubes (150mm×150mm×150mm) were cured using water-submerged curing until testing ages of 7, 14, 21 and 28 days when their densities and c...

Design And Development Of An Evaporative Cooling System For Fresh Fruit And Vegetable Storage

ABSTRACT An evaporative cooling system was developed with locally available materials. The system was aimed at providing lower temperature and higher relative humidity necessary for extending the shelf life of fruits and vegetables. The performance of the cooler was evaluated in terms of temperature drop, humidity gain, cooling efficiency and quality assessment of the stored products. Two categories of test were carried out on the cooler with the chosen absorbent materials: the no-load test a...

Design And Development Of A Hybrid Solar/Charcoal Fish Smoke-Dryer

ABSTRACT  An indirect, natural convection solar-assisted charcoal smoking system was designed and fabricated in one of the host communities of the Federal University of Technology, Owerri where most of the fish farmers and processors adopt the conventional method of drying fishes, that is, using firewood. This method which works well during the dry period of the year is very inconvenient during the rainy season.  Given the excessive heat generated by firewood and its resultant effect on the...

Development of a Periwinkle Shell Capsule For The Control of Water PH For Poultry Farming

ABSTRACT           This study was carried out to solve problems associated with low groundwater pH encountered by poultry farmers (using Owerri as a case study) which results to birds‟ mortality and low production of eggsand meat. Groundwater samples from different areas in Owerri were collected from boreholes for characterization using standard methods and the pH values were assessed. The results showed that pH of groundwater in the study area ranged from 4.8 to 5.8 through dry and ...

EFFECT OF INITIAL LAND PREPARATION METHODS ON SELECTED SOIL PHYSICAL PROPERTIES IN AFRAM PLAINS, GHANA

Abstract The objective of the study was to determine the most appropriate methods of initial land preparations in Afram Plains based on their effect on selected soil physical properties such as dry bulk density, porosity, hydraulic conductivity and available water content. The study also sought to estimate the cost of preparing farm lands in the Afram Plains. The study was conducted in Odumesua in the Afram Plains District sampling soil from fields prepared with three identified and categoriz...

Effect Of Biochar On Soil Physical Properties, Water Use Efficiency, And Growth Of Maize In A Sandy Loam Soil

ABSTRACT There has been claims that biochar improves water retention in soil and aid in improved crop productivity. Hence, recent conservation practices in the area of agricultural lands have focused research attention on the performance mechanism of biochar. In this study, the effect of corn cob biochar particle sizes ( FBP (

Design, Construction And Perfromance Evaluation Of A Drip Irrigation System

ABSTRACT A gravitational drip Irrigation system was designed and constructed using available materials; and tested for the use of small scale farmers.

Calibration And Validation Of The Fao Aquacrop Model For Tomato (Solanum Lycopersicon) In The Coastal Savannah Agro-Ecological Zone Of Ghana

ABSTRACT Two field experiments were conducted to compare the growth and yield of tomatoes using experimentation and FAO AquaCrop model at the University of Cape Coast Teaching and Research Farm in the Cape Coast Metropolitan Assembly of the Central Region of Ghana. The Randomized Complete Block Design was used with four (4) treatments and four(4) replications for the two experiments. The treatments used for both experiments were T1 – Full irrigation (100 %), T2 – 90 % irrigation, T3 – 8...

Shelf-Life And Quality Characteristics Of Smoked Catfish (Clarias Gariepinus) Stored In Composite Packaging Materials

ABSTRACT Smoking and drying are major methods of processing and preserving fish in Nigeria. However, inadequate packaging using cartons, baskets, jute and mat bags with transparent polyethylene are the most common which offer little protection against external agents and has been a major challenge. There is dearth of information on the developments of appropriate fish packaging thereby limiting fishery preservation to small scale business. The use of composite packaging materials for storage ...

Soil Displacement Using Disc Plough In A Clayey Loam Soil

ABSTRACT Soil displacement by tillage is a major contributor to the redistribution of soil particles within the soil profile. The extent of soil redistribution eventually has an effect on the performance of crop production. It is, therefore, valuable to investigate soil displacement by disc plough since it is known to be the widely used primary tillage implement in Ghana. Consequently, a study was conducted at the Livestock and Poultry Research Centre of the University of Ghana (LIPREC) with ...

EFFECT OF HERMETIC STORAGE ON THE QUALITY AND SHELF LIFE OF ‘OBATAMPA’ MAIZE (Zea mays L.) VARIETY

ABSTRACT Control of the storage pest Larger Grain Borer (LGB) (Prostephanus truncates) and aflatoxin contamination by the mould Aspergillus spp. are the major challenges to maize storage in Africa. In this study, the effect of hermetic storage on LGB and Aspergillus spp. during maize storage was evaluated. A 2 x 3 factorial experiment of two storage atmospheres (hermetic and non-hermetic) and infestation levels (LGB, Aspergillus spp. and uninfected control) were evaluated during the storage...
