Cultivating traditional upland rice cultivars on nutrient depleted soil causes poor and low yield. Little attention is paid to performance of inter-specific NERICA cultivars grown on nutrient deficient soil augmented with different types of compost. Therefore, field trials were conducted during 2010 and 2011 planting seasons in Ibadan to evaluate growth, dry matter, nutrient uptake efficiency and grain yield of upland rice grown on nutrient deficient soil augmented with different types of compost. There were nine treatments comprising of three upland rice cultivars: NERICA I, NERICA II and ofada, two compost types applied at the rate of 8 t·ha-1: poultry dropping + maize stover (PDMC) and cattle dung + maize stover (CDMC) and control. The treatments were laid out in randomized complete block design and replicated three times. CDMC enhanced growth, nutrient use efficiency, dry matter and grain yield of upland rice cultivars. Performance of ofada was better than NERICA cultivars. N (24.55 g), P (12.45 g) and K (35.41 g) uptake concentration and grain yield (5.45 t/ha) were highest in ofada plots augmented with CDMC. Residual effect of compost on growth, yield and nutrient uptake efficiency of upland rice on nutrient deficient soil was marginal.

The cultivation of desirable aquatic organisms is becoming increasingly important as one of the fastest-growing agro-industrial activities in the world. Nigeria, over the years, practised traditional methods of aquaculture in tidal pools and floodplains of inland waters. Recently, the coastal region has been the focus of aquaculture development with introduction of cage culture system. Nigeria is one of the top aquaculture producers in Africa with numerous opportunities for large-scale production, and 80% of production is from small-scale farmers who involve in brackish and freshwater cultivation, except mariculture which has several setbacks. Nigeria is yet to show feasible interest in non-fed aquaculture （macroalgae） which is among the world＇ s most efficient mass producer of proteins and other products. Constraints to production in the industry have been identified, while the prospects can be achieved by expanding aquaculture zones, enhancing management practices of production systems and improving product quality with the resultant creation of jobs, regular income and investment, etc.. This paper explores the status of aquaculture in Nigeria, and the components and the systems of commercial aquaculture were elucidated.

Background: Glaucoma, a group of diseases that have optic neuropathy as a common end point, is the leading cause of irreversible blindness worldwide, accounting for 4.5 million blindness, which is about 12% of global blindness. This study aimed to assess the prevalence, awareness and risk factors associated with glaucoma in a rural community of Ekiti State. Methodology: This was a cross-sectional study conducted during a health outreach. All adults present during the outreach were enrolled into the study and screened for glaucoma and a semi-structured self-administered questionnaire was used for data collection. The validity of the questionnaire was tested at Ijero-Ekiti community before being used for this research. Data obtained was analysed using SPSS version 20 and p-value was predetermined at ≤ 0.05. Results: Majority of respondents were aged 60 years and above with a mean age of 55 ± 11.7. Majority (73%) were females and 41% had secondary education. Prevalence of glaucoma was 10.7%;36% of respondents had heard about glaucoma;and 43.2% of those that had heard were not aware that it can lead to blindness. Increasing age, level of education, procurement of glasses from friends/relatives/roadside, using eyes drop not prescribed, history of previous eyes injury and family history of glaucoma were factors identified as having significant relationship with glaucoma. Conclusion: Glaucoma is prevalent in the community (10.7%). However, level of awareness about the disease (36%) was low. Factors, such as age, level of education, procurement of glasses from quacks, use of eye drops not prescribed, previous injury to the eyes and family history of glaucoma, were shown to have significant relationship with glaucoma. There is need to increase community awareness on glaucoma as a major cause of blindness and the risk factors associated with it. Community screening for people above 40 years for glaucoma is also recommended.

Background: Pre-eclampsia complicates 2% - 8% of pregnancies. Various efforts have been put forward for its prevention and treatment. Magnesium sulphate is presently the recommended drug for the prevention and treatment of eclampsia and severe pre-eclampsia. objectives: The study aimed to compare the serum magnesium in a healthy pregnant women and pre-eclamptic women. It determined demographic characteristic of the study population and recommended the prophylactic usage of magnesium sulphate in pregnancy in our environment. Method: This was a prospective case control study comparing the serum magnesium levels in pre-eclampsia and normal pregnancy tertiary hospitals. The women who satisfied the inclusion criteria were recruited in the two groups (seventy five in the healthy pregnant women and seventy five in the pre-eclamptic women). The blood samples were collected and analysed for the serum magnesium and urine sample for urinalysis. Result: Total of 150 patients comprises 75 normal pregnant women and 75 cases of pre-eclampsia. The mean serum magnesium in the normal pregnant women was 0.73 (±0.14) mmol/L while in preeclampsia the level was 0.58 (±0.17) mmol/L. This is statistically significant (t = 6.120, p = 0.000). There was significance difference in the mean age of patients with pre-eclampsia and normal pregnancy. The mean parity in the pre-eclampsia was 0.80 and in the normal pregnancy was 1.4 and was statistically significant (t = 3.40, p value onal age of the pre-eclamptic was 36.5 weeks while it was 28.7 weeks in the normal pregnant women (t = 10.80, p = 0.000). Conclusion: The findings in this research work revealed that the pre-eclamptic women have lower serum magnesium level compared to the normal pregnant women, and it may therefore be interesting to do a larger multicenter study with possibility of developing a marker for this disease of theories.

A nursery experiment was conducted at Cocoa Research Institute of Nigeria to evaluate the impact of manure on cashew seedlings. Treatments consisted of biochar, compost, combination of biochar + compost and a control. Treatments were applied at rate of 0 g (control), 5 g compost, 5 g biochar and 2.5 g each of biochar and compost combination into 5 kg soil in pots, laid out in a completely randomized design (CRD) with three replications. The experiment was monitored for four months in the greenhouse. Data were collected on number of leaves, plant height, stem girth, soil nutrient composition and nutrient uptake, all analyzed using analysis of variance. The treated soils were also assayed on Potato Dextrose Agar for associated mycoflora. The study showed that the soil PH, N, P, K, Ca and Mg were equally enhanced significantly relative to the control, while Aspergillus, Trichoderma, Beauverie, Penicillium, Lasiodiplodia and Rhizopus cultured treated soils shows that Trichoderma harzianum and Beauverie bassiana were significantly higher in combination of biochar and compost treated soil and posed that their bio-control potential is coupled with soil fertility enhancement characteristics. The results also indicate that stem girth and number of leaves were significantly (P ≤ 0.05) different with respect to applied treatment at the first month after treatments application. The leaf area was not enhances with the application of biochar. Combination of biochar + compost significantly enhanced number of leaves and stem girth at the 4th and 12th weeks after planting. Similarly leaf K and P uptake were significantly (on of organic compost and biochar irrespective of whether combined or not compared to the control seedlings. The effect of biochar and compost on cashew leaf Ca and Mg uptake were not significantly different from the control but had a higher value relative to the control. It could therefore be recommended that addition of compost an

Contamination by heavy metals is a serious threat to aquatic systems due to their level of toxicity at elevated levels. The pollution of urban watersheds is of particular concern because of its potential impact on the watershed ecosystem and the receiving larger water bodies. This study assessed the occurrence and distribution of cadmium, copper, nickel, lead and zinc in water and sediment samples collected from three urban watersheds in Lagos, Nigeria. The concentrations of metals were determined using atomic absorption spectrometry. The health risk index (HRI) of water usage was evaluated for both adults and children. HRI for cadmium and lead in some of the watersheds recorded HRI > 1 values, a cause for health concern. The pH of water ranged from 6.48 ± 0.28 - 6.54 ± 0.47 (2016) and 6.18 ± 0.56 - 6.53 ± 0.17 (2018) respectively while, for sediments, the pH values ranged from 6.14 ± 0.48 - 6.9 ± 0.15 and 5.38 ± 0.22 - 6.4 ± 0.38 for 2016 and 2018 respectively. The levels of metals in the water samples during the 2016 sampling cycle were found to be within the World Health organization (WHo) guideline limits for drinking water. However, the 2018 cadmium, lead and zinc concentrations for Ira-Ipaye and Akesan watersheds exceed the WHo guideline limits. Cadmium was not detected in Ira-Ipaye and Akesan 2016 sediment samples. Statistical t-test and analysis of variance (ANoVA) were used to ascertain significant differences of metals concentration in the three watersheds. The pH and metal concentration values obtained for water and sediment for the year 2016 and 2018 were non-significantly different.

Energy security, cost of production and environmental constraints have necessitated the need for proper energy utilisation in the manufacturing industries. This work analysed energy and production data from an aluminium extrusion plant in Lagos, Nigeria for energy efficiency, exergy efficiency (or process?efficiency), energy cost per unit of production, Co2 emission and pollution?rate?index. The input-output energy analysis method was used to estimate the?embodied energy intensity. The pollution rate, energetic and exergetic efficiencies were estimated from the exergy analysis. The Co2 emission was estimated?from IPCC guideline on greenhouse inventories and the energy cost of unit?produce was estimated from energy cost accounting method. The five-year average thermal and electrical utilisation ratio was 45/55, which deviated from the 70:30 of the global best practices. The embodied energy intensity for the five years’ ranges between 2.31 - 162.3 GJ/t which is in excess of the recommended?range of (2.9 - 3.2 GJ/t). The mean energy efficiency for the five year was 79.4% and the mean exergetic efficiency was 57.8% indicating that production was well?managed (>50%) with energy wastages very high in boiler energy conversion. The total energy used was 16 MJ and Co2 emitted is 1.01 × 1011 g during the study period. The average pollution rate index for the plant was 0.8695 indicating that the plant is negatively impacting the environment due to technological limitation of the energy conversion process employed in the manufacturing plant. The study reveals a distortion of the recommended best practice in energy balance ratio which accounted for the high average cost of production (N 4418.3/t);process efficiency was generally low thereby negatively affecting industrial output for the company.
