Growth parameters such as germination count, plant height, and number of trifoliate leaves per plant, number of branches per plant, flower production dynamics and dry matter determination were measured, while harvest index, shelling percentage, number of seeds per pod, see weight pods per plant and grain yield were measured at harvest as yield components. Data were subjected to statistical analysis of variance (ANOVA) using SAS Institute. Significant means were separated using Duncans Multiple Range Test at 5% probability level. Results revealed that there were no constant trends in growth parameters response to population density. Plant height and flower production decreased with increased population density, while number of leaves per plant and dry matter increased with increasing population density. There was no appreciable effect of population density on branching. All these parameters were significantly (p≤0.05) affected with variety, while there was no significant (p≤0.05) interaction effect. Most yield components decreased with increasing population density while grain yield however, slightly increased with increasing population density. All yield parameter and grain yield significantly varied with variety, while there were no appreciable interaction effect. In conclusion, a population density of 88,000 plants /ha gives the highest growth and grain yield. While, variety, IT97-568-18 gives the higher growth and grain yield than other varieties studied.","PeriodicalId":194209,"journal":{"name":"Nigerian Journal of Pure and Applied Sciences","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134071632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic amendments included cassava peels, plantain peels, eggshells, and poultry droppings, while inorganic amendments included NPK and Urea. In this study, three (3) bacteria were characterized and dealt with: Bacillus amyloliquefaciens, Bacillus proteolyticus, and Providencia rettgeri. To determine their biodegradative capabilities, these isolates were tested on a variety of hydrocarbons. In addition, the antibacterial activity of the bacteria was tested in vitro against extracts of Moringa oleifera, Vernonia amygdalina (Bitter leaf), Ocimum gratissimum (Scent lLeaf), and Telifairia occidentalis (Ugwu) at different concentrations (20%, 13%, 10%, 7%, and 3%). Using the maceration procedure, the plant materials were extracted with ethanol and methanol. The bacteria were resistant to the various concentrations of plant extracts, according to the results. The methanolic and ethanolic extracts of Vernonia amygdalina (bitter leaf) had the maximum inhibition zone, measuring 6.00 ± 0.00 mm. Furthermore, all isolates were resistant to crude oil, engine oil, heptane, and benzene in antimicrobial tests on hydrocarbons, with Bacillus amyloliquefaciens having the highest level of susceptibility (18 mm) to pyridine. However, the bacteria all demonstrated broad spectrum susceptibility to the commercial antibiotics used as a control, with the exception of Providencia rettgeri, which proved resistant (5 mm) to Ampiclox (APX), Zinnacef (Z) and Amoxacillin (AM).","PeriodicalId":194209,"journal":{"name":"Nigerian Journal of Pure and Applied Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134146577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is need for study that can evaluate natural preservatives and physicochemical properties of some plants. In the present study, survey of indigenous plants commonly used for preservation of fruits was conducted using one hundred structured questionnaires randomly administered on fruit-sellers to elicit information on spoilage as threat affecting sales of fruits in Abeokuta. Also, biochemical constituents and physicochemical properties in the leaves of most plants used for fruits preservation were determined using standard procedure. Data were analysed using Statistical Analysis System. Means were separated using Duncan’s Multiple Range Test at 5% level of significance (p < 0.05). Nauclea latifolia, Chromolaena odorata, Psidium guajava, Azadirachta indica, Moringa oleifera and Aloe vera were the plants commonly used for preservation of fruits in the study area. Fruit spoilage (84.0%) was the major threat affecting the sales of fruits in Abeokuta. Saponin (0.68±0.03 mg/100g) and terpenoid (0.22±0.08 mg/100g) were significantly higher (p < 0.05) in A. indica leaves as well as alkaloid (16.49±0.01 mg/100 g) in M. oleifera leaves. Also, phenol (0.41±0.02 mg/100g) and flavonoid (0.71±0.09mg/100g) were significantly higher (p < 0.05) in C. odorata and A. vera leaves. Phytate (0.35±0.01 mg/100 g) and oxalate (0.32±0.03 mg/100 g) were significantly higher (p < 0.05) in the leaves of C. odorata. Furthermore, specific gravity of M. oleifera leaves (0.98±0.05) was significantly higher (p < 0.05) compared with leaves of other plants. Iodine value (81.65±0.03 mg/100 g) and acid value (22.72±0.07) were significantly (p < 0.05) higher in Aloe vera leaves. The study revealed that spoilage was the major challenge facing the sales of fruits in Abeokuta.

The gercacinid, Cardiosoma armatum (75±0.1 g) was exposed to acidified waters to evaluate the effects on its immune parameters. The crabs were exposed to pH 4.0, 5.0, 6.0 and 7.8 (control) for 28 days. The hematological parameters of control crabs and crabs exposed to varied doses of acidified water indicated a marked reduction. Significant (p<0.05) higher alkaline phosphatase and albumen were obtained in pH 4.0, 5.0 and 6.0 compared to control; other values were mostly similar to control. The highest superoxide dismutase (SOD) (252.61±0.06 min/mg pro) was recorded in control group, while highest CAT activity (2.08±0.16 min/mg protein) was recorded in crabs exposed to pH 4 treatment. Furthermore, the control group's SOD activity was significantly higher than the exposed groups. With a lower pH, the quantities of malondialdehyde increased substantially and were significantly different from the control group. While these findings demonstrate that changes in pH have limited impact on energy use, decreasing immune system conditions show that C. armatum is susceptible to pH variations and may be influenced in aquaculture, where a pH drop is more prominent.","PeriodicalId":194209,"journal":{"name":"Nigerian Journal of Pure and Applied Sciences","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131724273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Medicinal plants are now increasingly used alone or as an adjunct in the management of infectious diseases as a result of their claimed efficacy and safety. This research focused on evaluating the antimicrobial potential of ethanol fruit peel extract of Mangifera indica against isolated Urinary tract infection (UTI) pathogens. Urinary tract infection (UTI) bacterial strains (staphylococcus aureus, escherichia coli and pseudomonas aeruginosa) were isolated from midstream urine of infected students using standard procedures after which the isolated Urinary tract infection pathogens were subjected to antimicrobial susceptibility test by agar-well diffusion method (Cup plate method) and the mean diameter of growth inhibition zones (n=3) of the extract at different concentrations were compared against the controls (sterile water and ciprofloxacin). Ethanol fruit peel extract of Mangifera indica significantly and dose dependently inhibit the growth of all the isolated Urinary tract infection pathogens with E.coli exhibiting the highest inhibition zone ranging from 16.83 to 28.23 mm, this was followed by pseudomonas aeruginosa with inhibition zone of 24.33 mm and staphylococcus aureus least susceptible with 22.63 diameter of zone inhibition. Ethanol fruit peel extract of Mangifera indica demonstrated a dose dependent antimicrobial activity with more pronounced effect exhibited by E. coli suggesting that the extract is more effective against gram negative bacteria despite their permeability barrier, thus suggesting Mangifera indica fruit peel as a potential candidate for the management of bacterial infections especially those caused by gram negative organisms.","PeriodicalId":194209,"journal":{"name":"Nigerian Journal of Pure and Applied Sciences","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134204039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, honey of various types exhibit varying properties. Their therapeutic effects are determined by whether the honey is multifloral or monofloral, and also on the variety of nectars the honey is derived from. Manuka and Tualang types of honey were observed to possess anti-ulcer effects. However, no such report is available for University of Ilorin honey. This study therefore aimed to determine the gastroprotective effects of University of Ilorin honey in Wistar rats using two laboratory models for inducing ulcer (HCl/Ethanol and Indomethacin). Twenty rats each were assigned to four groups for each model of ulcer. The rats were treated for 12 days with the administration of distilled water (control), cimetidine (100 mg/kg b.w.) and University of Ilorin honey (250 mg/kg b.w. in one group and 1000 mg/kg b.w in another group). The rats were fasted for 24 hours after the last treatment. Then, the ulcerogens were given orally. After four hours, the rats were sacrificed, gastric juice was collected and the stomachs were examined for ulceration. The results revealed that pre-treatment with University of Ilorin honey reduced gastric index from 6.80±0.20 (1000 mg/kg b.w. to 2.40±0.24 (control) P<0.05 and 7.20±0.37 (1000 mg/kg b.w.) to 3.20±0.37 (control) P<0.05 in HCl/Ethanol and indomethacin induced ulcer models respectively. There was no significant difference in ulcer index between the cimetidine administered rats and the honey administered group (1000 mg/kg bw.), but the honey group (250 mg/kg bw.) was less effective than the cimetidine group in the models used. Also, there were no changes in gastric acidity in all the groups compared with the control group.

Two complete competitors cannot coexist indefinitely, therefore competitors must differ to some degree in their resource use. The research was carried to investigate how resources are partitioned among the species of sunbirds found in Federal College of Forestry, Jos. Opportunistic sightings along a 200m transect was used for observation. Sunbirds were observed using binoculars between 6:30 – 8am and by 4:30 – 6pm. Six transects were purposively selected in the study area. Sightings along a 200m transect was used to observe; species of sunbird, sex of individual sunbird species, species of flowering plant visited by the sunbird species, activity or behaviour performed by the sunbird (probing, insect hunting, roosting, perching etc.) and duration of activity. Descriptive statistics, ANOVA and post hoc test was used to analyse the data obtained. Results showed that forty-three (43) plant species were utilised by the four (4) sunbird species found in the study site with Corymbia torelliana and Hamelia patens having the highest number of visit. These four sunbird species observed were; Scarlet-chested sunbird, Variable sunbird, Green-headed sunbird and the Copper sunbird. Mean number of plants visited shows that Green-headed sunbird visited more plants than the other three species (28.89) which was highly significant (p=0.001). Copper sunbird spent the highest foraging time (67.71) which showed no variation with the other species (p=0.516). Females of the sunbird species visit more plants species and spent more time foraging as compared to the males although there was no variation (p= 0.984 and p= 0.906 respectively). The activities of the males (perching, hovering, probing, feeding) was higher than that of females and had a high level of significance (p=0.001). Callistemon citrinus, Corymbia torelliana, Eucalyptus camaldulensis, Hamelia patens, Parkia biglobosa and Ziziphus mucronata were utilised by all the sunbird species.

Two hundred and sixteen swabs were collected from the external surfaces of canned soft drinks and its handlers, thirty-six swabs each from cans and hand swabs were also collected from designated whole sellers known as Distributors. The samples were screened and analyzed using Spread Plate Method, Microgen GNA System for identification for enteric bacteria in three institutions in Zaria, Kaduna State. Kirby-Bauer disk diffusion method was employed for antimicrobial susceptibility test. The results showed that the total bacteria count of canned soft drinks and its handlers in the three institutions range from 1.0x104 to 3.0x107 cfu/ml. Fourteen species of the Family Enterobacteriaceae were identified. The predominant species observed on canned soft drinks were Citrobacter freundii and Klebsiella ozaenae while that of its handlers were Citrobacter freundii and Escherichia coli.

Grinded Biomass was agitated in the solution of the mixed surfactant, allowing the extracted oil to be liberated from the seeds as separate phase from the aqueous phase. The effect of SDS concentration, NaCl concentration, contact time and liquid/seed ratio on oil yield was studied. The extracted oil was subjected to Fourier Transform Infrared Spectroscope (FT-IR) characterization to determine the functional groups present in the oil.
