Water occurred naturally and it is used widely for drinking, cooking, washing, agricultural activities, population expansion, urbanization, generation of power, and industrialization. Availability and accessibility are used to estimate the percentage of the population using safe water sources. However, potable water is inaccessible and unavailable...
The need for fish arises from the need for protein in human’s diet. Protein is required both for maintenance and growth of worm-out cells. Protein could be sourced from plants-vegetable protein, as well as animals-animal protein, the latter mainly in the form of fish and meat. Fish is a cheap source of protein for human consumption. For this reas...
The physicochemical parameters of surface water surface of Ero Dam for irrigation were assessed. Water samples were selected from three locations (upstream, downstream and control). Tested parameters for water samples are pH, electrical conductivity (EC), total dissolved solids (TDS), calcium (Ca2+), magnesium (Mg2+), sodium (Na+), potassium (K+),...
Experiment was carried out in the department of Agricultural and Bioresources Engineering, during the period of August to October, 2017. The hydraulic performance of a developed drip irrigation system was assessed. The experimental work was conducted on field with irrigated field area of 7 m x 3 m and lateral spacing was 0.35 m. Sixty (60) hospital...
The present study attempts to relate the soil organic carbon content with four different land uses (Faculty of Agriculture Teaching and Research farm, cashew plantation and Agricultural and Bioresources experimental farm and oil palm plantation) which come under South west, Nigeria. The objective of the study was to assess the effects of different...
The aim of this work is to measure the fuel properties of mango seed biodiesel and its blends with diesel fuel. The oil was extracted by soxhlet extraction method. The high free fatty acid (FFA) value of the oil produced necessitated, acid pretreatment prior to base transesterification with methanol using sodium hydroxide as catalyst which resulted...
The future of agricultural mechanization and machinery development are interrelated and the successful implementation of mechanized agriculture not only depends on the availability of machinery but also on the positive response of government and perception of farmers and other users. Agricultural mechanization in Nigeria is based on regional patter...
The future of agricultural mechanization and machinery development arc interrelated and the successful implementation of mechanized agriculture not only depends on the availability of machinery but also on the positive response of government and perception of farmers and other users. Agricultural mechanization in Nigeria is based on regional patter...
The present level of irrigation system and poor output level of agricultural and horticultural products have triggered the need to look for a better management strategy under the current irrigation system. In order to suggest a feasible option, this study examines the present irrigation management structure in Benin-Owena River Basin Development Au...
Water hyacinth (Eichhornia crassipes) despite its acclaimed “high nuisance value”, prove having immense economic value to the fisher folks in the riverine areas of Ondo State, Southwest, Nigeria when used as passive Fish Aggregating Device (FAD) Extensive Culture Receptacles, in a two-year study. The WH-FAD; WH, denoting Water hyacinth, isolated 0....
This study was performed to assess termite mound inherent property as additive for improvement of soil strength of construction purpose in Nigeria. The mound on the Rhodic Acrisol was sampled from top at 0-60 cm, 60-120 cm and 120-180 cm intervals through a vertical section. For the Rhodic Acrisol, three samples were sampled from bottom at 0-60 cm,...
The study was performed to examine catfish (Clarias gariepinus) effluents on the quality of soil in La-gos State, Nigeria. Five fish farms with highest stock density were selected for evaluation. The soil sampling was collected at 10 metres apart before the effluent discharged site; at the effluent dis-charged site; 10 metres after the effluent dis...
Catfish production is one of the largest segments of fish culture in Lagos State, Nigeria. However, catfish effluents, which usually deteriorate the environment, need to be controlled. The effect of paddle-wheel aerator in catfish effluent was evaluated. The volume of catfish effluent was collected into two basins and diluted at given ratios. The p...
A study was carried out for five weeks to examine physical and chemical parameters of modal soil in selected areas in relation to pond setting and productivity in Lagos State, Nigeria. Physical (water temperature, soil permeability, bulk density and textural) and chemical parameters (pH, nitrogen and phosphorus) were determined according to standar...
The reuse of catfish pond effluent by irrigation can make a significant contribution to the integrated management of our water resources. The study was done to evaluate African catfish (Clarias gariepinus) quality pond effluent quality and its suitability for irrigation. Forty (40) samples were collected from five ponds. Physical and chemical param...
This study assessed the impact of catfish pond effluents discharges on the quality of subsurface water where five catfish farms were located. Water samples were taken at depth of 0-200 cm and at intervals of 50 cm distance of each water source from neighbouring fishponds. Water quality indicators-pH, Turbidity (TB), Total dissolved solids (TDS), To...
This study examined the effect of dumpsites on ground and surface water qualities. Study water samples were collected at selected zones and designated as A, B and C for both the ground and surface water respectively. Leachates were collected at dumpsites in the zones. Physicochemical properties of samples examined were pH, and surface water that we...
Recent happening globally especially in the developing country such as Nigeria has shown that there is need to conduct a survey on medical waste management due to direct or indirect adverse effect on the environment and human health. The medical waste management in private hospitals in Lagos State was assessed. Information on hospitals was collecte...
The study was performed to examine catfish (Clarias geriepinus) effluents on the quality of soil in Lagos State, Nigeria. Five fish farms with highest stock density were selected for evaluation. The soil sampling was collected at 10 metres apart before the effluent discharged site; at the effluent discharged site; 10 metres after the effluent disch...
This paper advocates habitat conservation and ecological studies with special reference to the physico-chemical characteristics of Majidun stream. The aim of this study was to assess the potential impact of catfish (Clarias gariepinus) effluents on water quality of stream where five catfish farms are localized. The constituents monitored include wa...
Technical factors that have potential influence on the performance of fish ponds in Lagos State were assessed. Questionnaires and on-the-spot assessment were used for collecting information on pond construction materials, water sources and pond operational problems. Variations in pond water depth during wet and dry seasons were measured using a lev...
