ABSTRACT Rattan cane is a relatively abundant lignocellulosic in Africa and Asia that could be used for wood-cement composite production. However, rattans tend to inhibit cement setting. This study investigated the effects of cane peeling and aqueous extraction on maximum hydration temperature (Tmax) and setting time (tmax) rattancement- water systems using Calamus deerratus and Lacosperma secundiflorum rattan species. Peeling was done manually to remove the silified epidermis before hammer-m...
ABSTRACT The increase in pork consumption globally in recent times has led to a corresponding increase in pig production with more people being employed in the industry to provide the needed services. Pigs are known to generate a lot of noise which could constitute a potential health hazard and against which remedial measures must be taken. The establishment of the levels of noise generated in piggery production units and their possible consequences on the workers in such units was the main o...
ABSTRACT An assessment of farm transportation system to ascertain the availability of transportation for the evacuation of farm produce was undertaken in Osun and Oyo states of Nigeria employing printed questionnaires and personal communication as means of information collection. 20% of the farmers reside at between one and three km from their farms while for the remaining 80%, it ranges from four to 16 km. 17.6% of the farmers travel between one and three km to sell their produce while for t...
ABSTRACT Gravitational drip irrigation system was developed using available materials. The system consisting of 4.0 Ilhr Netafim pressure-compensating emitters was used to irrigate 0.0015 ha of land where sweet com was planted under variable water applications in a randomised complete block design with three treatments. Treatment one (WI) received water once per week, treatment two (W2) received water twice per week, while third treatment (W3) received water thrice per week. WI received 229mm...
ABSTRACT A study was undertaken to assess the tractor-hiring unit of Edo state, Nigeria. The criteria used were fleet of equipment, personnel and workshop facilities and its impact on the farming populace in the state. The study adopted the use of a questionnaire and interview schedules. Among the information requested from the respondents were access to services rendered by the unit and increment in farm sizes. Records available at the headquarters and zonal offices of the unit provided addi...
ABSTRACT: The present study assessed water quality parameters and attempts to compare four different Water Quality Indexes (WQIs) for consistency, similarity and reliability in assessing the water quality of river Benue -an inland river- under wet and dry seasons. The results demonstrate that River Benue is continually being polluted in both dry and wet seasons by different sources, particularly domestic sewage and storm runoffs from farmlands. The quality of the water generally excee...
ABSTRACT Two layered rattan cement composite were made from Calamus Deeratus and Laccosperma Secundiflorum particles using cement:
ABSTRACT Leaf Area Index (LAI) is a concept that cuts across agricultural sciences and agricultural engineering with an encapsulating feature in environmental engineering. It is one of the most difficult 10 quantify properly owing to large spatial and temporal variability.
ABSTRACT Sustainability of agriculture is dependent upon availability of reliable climatic data for planning. Daily and monthly data were obtained for Ibadan, Nigeria from International Institute of Tropical Agriculture (niA) automatic weather station and Nigerian Meteorological Agency (NMA) manual weather station.
ABSTRACT Earth dam failures could result in the loss of lives, damage to properties, health, environmental and social problems. Distressed dams cost a lot of resources and inconveniences to remediate. There is paucity of data on failures and distresses of many earth dams located in the north-eastern part of Nigeria. This study was designed to determine the geological, hydrometeorological, engineering factors and soil properties responsible for the failures and distresses of earth dams. A tota...
ABSTRACT Locally processed rice (Oryza sativa L.) is characterized with high percentage of broken grains and impurities which impair the quality and reduces the market value. Reducing the proportion of broken rice and impurities after milling remains a challenge. There is therefore a need to develop a machine which cleans and grades the rice kernels based on quality. The objective of this work was to develop a cleaner - grader to improve the quality of milled rice. The physical and aerodyna...
ABSTRACT Tomato (Lycoperscium spp.) is an important component of daily dietary intake with seasonal and geographical variation in its production. They are usually in short supply in the dry season and effective storage in the fresh state still poses a challenge. Pre-treatment methods have been reported to improve drying characteristics of fruits and vegetables but there is dearth of information on drying of indigenous variety of tomato despite its high nutritional value. Pre-treatment methods...
Abstract The prevailing wind speed and direction in an environment are critical factors in farmstead planning as they influence the appropriate location and orientation of structures in order to reduce wind load impact and promote a healthy environment. The failure of farm structures especially with roof blown-off arising from wind load has become rampant in Ibadan environ in recent time and an urgent solution is desirable. In this work, an attempt is made to develop a wind rosette for Ibadan...
Abstract: Fruit trees am hardly ever sought for their wood until recently. Fruit trees like C. alhidum is now being used for structural and non structural purposes in city suburbs, This study investigated wood properties and few tree chplracteristies of C. albidum grown in AkinyeIe Local Government h (ALGA), Ibadaa, Oyo State, Nirk The dm was to mitigate, the dearth of information on these &atut.cs in elation to its utitdon. Samples %re collected from five emerging settl&ents in the; study ar...
ABSTRACT Celosia Argentea was planted on Agricultural and Environmental Engineering Department experimental field.
