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... Continue Reading
ABSTRACT: This study was carried out in Udi, Udenu and Nsukka Local Government Areas, in Enugu state. The effects of liquid wastes from automobile workshops on some selected soil properties of the study area were investigated. Auger samples were collected at two depths, (surface, 0- 20cm) and (subsurface, 20- 40cm) of automobile wastes... Continue Reading
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... Continue Reading
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...

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... Continue Reading
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... Continue Reading
Cassava is produced in a large quantity in Nigeria. One of the products emerging from its processing has turned out to be a major staple food in the nation, which is ‘garri’. Due to insufficient and inadequate processing equipment; cassava has been susceptible to wastage and ‘garri’ production has been reduced in scale, thereby... Continue Reading
ABSTRACT Generally the cutting and plate are made in plastics. The plastics are harmful and it has many disadvantages to us. By naturally we get leaves, Leaves by using this we can make cups. It is very cheap and it does not have any chemical effects. The Leaf cup is made by a solar tea leaf cutting machine. The machine is operated by the solar... Continue Reading
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... Continue Reading
ABSTRACT Flooding has been described as one of the most important environmental factors determining the distribution of salt marsh plants. We studied the impact of five water levels on the germination and establishment of the invasive cord-grass spartina deniflora. Plant house experiment was carried out to determine the effects of time and depth... Continue Reading
ABSTRACT A comparative study was conducted among organic waste materials namely coconut fiber, hair, sawdust and woodchips as crude oil absorbents. Twenty grams of each of these materials were wrapped in a pouch and submerged into two set-ups, Set-up A: Pure Crude Oil and Set-up B: Crude Oil with seawater, for an hour. Amount of oil absorbed was... Continue Reading
ABSTRACT The consumptive use of water assures all year round production of groundnut prone to the vagaries of weather and climate. This brought about the need to supply moisture that is naturally available through rainfall. The successful design of any irrigation system requires the knowledge of the consumptive use of water by the crop under... Continue Reading
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... Continue Reading
ABSTRACT Water 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.
