Appropriate Harvesting Stage Of Sweet-Stem Sorghum (Sorghum Bicolor (L) Moench) Cultivar For Optimum Bio-Ethanol Production In Namibia

ABSTRACT There has been growing global concern over dwindling fossil fuel supply. This development has led to increased interest in exploration of alternative energy sources, especially bio-fuel. Sweet sorghum (Sorghum bicolor), sugar cane (Saccharum officinarum), corn (Zea mays), wheat (Triticum aestivum), rape seed (Brassica napus), barley (Hordeum vulgare), sugar beet (Beta vulgaris), cassava (Manihot esculenta), oil palm (Elaies guineensis), sweet potato (Ipomoea batatas) and many more ha...

Effects Of Chemical Treatment On Nutrient Content And Palatability Of Senegalia Mellifera And Catophractes Alexandrii Bush-Based Feeds

ABSTRACT The objectives of this study were to determine: (1) the chemical composition of untreated Senegalia mellifera and Catophractes alexandrii; (2) the effect of NaOH and urea treatment at different levels (0%, 4%, 6% and 8%) on chemical composition of S. mellifera milled samples; (3) the nutrient composition of formulated diets from chemically and fibrolytic enzyme treated S. mellifera samples; (4) palatability of the feeds developed from S. mellifera, when fed to weaned Damara sheep. Sa...

Pesticide Regulations And Their Malpractice Implications On Food And Environment Safety

Abstract: Although pesticides have a positive effect on plant health in terms of insect pests and diseases control, increased productivity and improved crop storage, their malpractice impacts on food safety negatively. Pesticide residues and corresponding metabolites are left as runoff to the environment affecting non-targeted organisms like fish, bees, butterflies, birds and other beneficial organisms in soil and water bodies. Moreover, the application of pesticides in non-agriculture activi...

Assessment of Crop Storage Structures in Swaziland

ABSTRACT A survey was carried out to identify the types of crops popularly stored, the structures commonly used and problems experienced with produce storage in the Kingdom of Swaziland. Respondents included operators of government storage facilities, non-governmental organizations providing food relief, millers, large-scale farms, homesteads and artisans who fabricate metal tanks. Maize, the national staple food, was stored by all homesteads essentially for family consumption. It was the com...

Effect of Selected Pre Treatment on Setting of Cement Composite from Two Rattan Species

Effect of Selected Pre Treatment on Setting of Cement Composite from Two Rattan Species. AbstractThe effects of aqueous extraction and removal of vilified epidermis from rattan canes on the maximum hydration temperature (Tmax) and settling time (tmax) of two rattan cane species, Calamus deerratus and Lascosperma secundiflorum, mixed with Portland cement were investigated. Max ranged from 37.0 to 58.6oC and from 43.1 to 56.8oC for the C. Detritus and L. secundiflorum composites respectively wh...

Characterisation Of Fuel Briquettes From Gmelina Arborea (Roxb) Sawdust And Maize Cob Particles Using Cissus Populnea Gum As Binder

ABSTRACT Large quantities of agricultural and mill residues which are generated annually in Nigeria constitute environmental health hazards. Densification of these residues which is a major way of converting them to high quality fuel has not been adequately studied in Nigeria. The objective of this study was to develop and evaluate a system for briquetting and combusting Gmelina arborea sawdust and maize cob particles. Gmelina arborea Sawdust (GS) was obtained from a small-scale sawmill in Ib...

Effects Of Cane Peeling And Aqueous Extraction On Compatibility Of Two Rattan Species With Portland Cement

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...

Assessment Of Noise Levels Generated In Swine Production Units In Ibadan, Nigeria

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...

Evaluation of Farm Transportation System in Osun and Oyo States of Nigeria

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...

Performance Evaluation Of Drip Irrigation System Using Sweet Corn Under Variable Water Application

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...

Assessment of the Edo State of Nigeria Tractor Hiring Services

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...

Comparison of water quality indexes for inland river

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...

Strengths and Sorption Properties Of Cement Bonded Composites Made From Calamus Deeratus And Laccosperma Secundiflorum Canes

ABSTRACT Two layered rattan cement composite were made from Calamus Deeratus and Laccosperma Secundiflorum particles using cement:

Evaluation Of Three Methods For Estimating Leaf Area Index Of Cowpea (Vigna Unguiculata)

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.
