Methods of poultry manure application and its effect on growth and yield of Okra (Abelmoschus esculentus L.)

This study examined the effect of methods of fertilizer application on growth and yield of okra. The experiment was conducted within the research  plot of Crop Production Technology Department, Federal College of Forestry, Ibadan. Poultry manure was applied at varying levels using different  methods of fertilizer application (Ring and Broadcasting methods). The experiment was a 2 x 2 factorial laid out in a Randomized Complete Block Design (RCBD) having five (5) treatments which includes T1 – 2 Kg/ha of poultry manure and ring method, T2–2 Kg/ha of poultry manure and  broadcasting method, T3– 4kg/ha of poultry manure and ring method, T4 – 4 Kg/ha of poultry manure and broadcasting method, T5 – Control replicated three (3) times. Growth and yield parameters measured were plant height, number of leaves, stem diameter and fruit weight. Data collected were subjected to Analysis of variance (ANOVA) and the means were separated using Duncan Multiple Range Test (DMRT) at 5% level of probability. The result obtained showed that all the treatments favorably influenced the growth parameters of okra although T4(poultry manure and broadcasting) at 4kg/ha performed best while the least performances were recorded in T3(poultry manure and ring method) and T5 (control) plots. In addition,T4(poultry manure and broadcasting) at 2kg/ha had the highest number of fruits recording 242.0 while T5 (control) recorded least with 86.0. Broadcasting method at 4kg/ha and 2kg/ha levels of application performed best at both the vegetative and yield parameters assessed while the control plot recorded the least performance. In conclusion, since T4(Poultry manure and broadcasting)at 2kg produced the highest  number of fruits, it is therefore recommended to farmers for optimum growth and yield of okra.

Fibre Characterization of Cassava Peel Leaf Meal and Its Utilization by Broilers

One hundred and twenty ( n = 120) day old broiler chicks with an average weight (100.00±7.00g) were randomly allotted to four dietary treatments, with cassava peel leaf meal (CPLM) as replacement for maize at (starter and finisher phases).The trial was in three phases of adaptation  (1-2week),starter (3-5week) and finisher (6-9week).Thirty broilers chicks were assigned to each of the four treatments, while was replicated three times at 10 chicks each. Performance of the chicks such weight gain, feed intake and carcass yield was evaluated and the proximate and fiber quality of the diets and CPLM were also determined. Data obtained for performance evaluated was analyzed using ANOVA, while significant means were separated by SAS of the same package. The outcome revealed that CPLM had (89.93%) dry matter, (18.93%) crude protein and (43.28%) NDF, with anon-significant (p< 0.05) variation in weight gain, enhanced (p< 0.05) feed intake and depressed (p< 0.05) feed to gain ratio as CPLM inclusion increased. Dressing percentage values (69.00-73.00%) were obtained on the treatments. CPLM inclusion (0, 15, 30 and 45%) as replacement for maize in the diets of broilers produced a favourable performance.

Seed metrics for genetic and shape determinations in African yam bean [Fabaceae] (Sphenostylis stenocarpa Hochst. Ex. A. Rich.) harms

Open Access JournalThe metric measures on seeds, their correlation and relationship are important for systematic breeding for seed yield and shape determination. Variations among eighty genotypes of African yam bean (AYB) for six metric seed characters (seed length, width and thickness and their ratios) were evaluated in this study. Paired comparison among the six characters revealed very high significance (P < 0.001), approving the six traits as unique parameters for evaluating AYB. They equally exhibited high and substantial genetic variance: the genotypic proportion of the total variation ranged between 90 and 97%, broad sense heritability (81 - 94%) and genetic advances (14 - 31%). Seed length and width had the highest joint inheritance of 99.04%, the least, 4.32% was between width and WT as depicted by coheritability. Positive and significant (P < 0.05) phenotypic and/or genotypic correlation existed between seed width and thickness, the three ratios and seed length with the ratios except WT. Non-significant negative correlation existed between seed thickness with LT and WT. There were very reliable and highly significant linear relationships between the seed traits except for length and width whose relationship was non-linear. Breeding concentration on any of these traits may simultaneously influence the others. The seed shape indices were the metric ratios and the flatness index; they described the common shapes of AYB seeds as: round/spherical, oval/ellipsoidal, oblong and rhomboi

Paediatric traumatic rupture of the diaphragm

Traumatic diaphragmatic rupture is not a common injury in children. It is an important cause of morbidity and mortality, though diagnosis may be missed or delayed with atypical clinical presentation and confounding radiological features. A 4-year-old male presented with periumbilical abdominal pain, bilious vomiting, fever and progressive difficulty in breathing for two days. He had complained of vague left-side chest pain on return from the swimming pool about 6 weeks earlier. An initial chest radiograph showed a non-outlined left hemidiaphragm, a left pneumothorax, rightward mediastinal shift and suspected bowel in the chest. He could not afford a CT scan, hence a repeat chest radiograph was performed, which outlined the stomach with an air-fluid level in the left hemithorax.Keywords: Traumatic Diaphragmatic Rupture, Child, Atypical Chest pain, Blunt injur

SEISMICITY ANOMALIES OF M 5.0+ EARTHQUAKES IN CHILE DURING 1964-2015

The study of magnitude-frequency distribution of earthquake hazards in a region remains a crucial analysis in seismology. Its significance has varied from seismicity quantification to earthquake prediction. The analysis of seismicity anomalies of magnitude M => 5.0 earthquakes in Chile from 1964 to 2015 was undertaken by the present study with a view of reporting the trend of earthquake occurrences in the region. Chile has an area of about 756, 950 km2 with an extensive coastline of approximately 6,435 kms. It is situated in a highly seismically and volcanically active zone with a long, narrow strip of land between the Andes Mountains to the east and the Pacific Ocean to the west.It borders Peru to the north, Bolivia to the northeast, Argentina to the east and the Drake Passage in the far south. Of a total of 3,893 earthquakes that have been documented historically, magnitudes Richter 5.0 to 5.9 represent 92.6%, magnitudes 6.0 to 6.9 represent 6.8%, magnitudes 7.0 to 7.9 represent 0.6%, and magnitudes 8.0 to 8.9 about 0.1%. The quantity of earthquakes (a-value) revealed an estimate of 8.4. The b-value was estimated using Gutenberg-Richter (GR) and the Maximum Likelihood Estimation (MLE) methods. The estimated b-value using GR and MLE methods are 0.97 and 1.1 respectively, with an estimated average b-value ≈ 1. The present studies supprort the conclusion that Chile is seismically very active and prone to the recurrence of moderateto- great earthquakes in the future

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Inhibition of lipid peroxidation and free radical scavenging activities of methanolic leaf extract of Psidium guajava

Objectives: Studies have linked the generation of free radicals with the incidence of degenerative diseases. Antioxidants from plant origin have been proved to play a major role in mitigating against free radicals-induced oxidative damage. This study aimed at assessing the in-vitro and in-vivo antioxidant capability of Psidium guajava leafMethods: The leaves were collected and extracted with 70% methanol. Total phenolic, and flavonoids contents, 2,2-diphenyl-1-picrylhydrazyl and Hydroxyl radicals scavenging activities, and inhibition of lipid peroxidation potential of the extract were assessed. Furthermore, rats (n=21) randomized into three groups were exposed to 50, 150, and 250 mg/kg body weight of the extract for 30 days. Control animals (n=7) received corn oil, after which blood and liver were excised for antioxidant assay.Results: The extract is rich in phenolic and flavonoid compounds. It scavenged DPPH and hydroxyl radicals and inhibits lipid peroxidation in-vitro. In-vivo, it increased the activities of hepatic superoxide dismutase, catalase, glutathione peroxidase, and plasma paraoxonase, and the concentration of hepatic reduced glutathione and MDA.Conclusion: Psidium guajava leaf extract is a potential source of natural antioxidant compounds, capable of supplementing the body's antioxidant defense system
