A COMPARATIVE STUDY OF LOCAL GOVERNMENT AND COMMUNITY-BASED ORGANISATIONS IN THE DELIVERY OF SOCIAL SERVICES IN SELECTED STATES OF SOUTHWESTERN NIGERIA (1997-2005)
(2007) POPOOLA, OLADEPO OLUFEMI
This study examined and compared the delivery of social services by Local Government and Community-based Organizations (CBOs) in selected states of Ekiti, Ogun and Osun of Southwestern Nigeria between 1997 and 2005. The social services which the study focused on were: road, water, electricity, health care and education. This was with a view to ascertaining the usefulness of co-production strategy to the delivery of social services. Both primary and secondary data were used for the study. Primary data were obtained through the use of structured questionnaires, oral interviews and observation techniques. Four hundred and forty questionnaires were administered on the leaders (Chairmen, Secretaries and Treasurers) of Community Development Councils (CDCs) using stratified sampling technique. Also, five hundred and eighty two questionnaires were administered on the senior staffs of local government that were directly involved in the delivery of social services using stratified sampling technique. The questionnaires assessed respondents' opinions not only on the performance of local government and CBOs in the delivery of social services, but also on local government delivery vis-a-vis community delivery. The questionnaires also assessed respondents' views on the relevance and usefulness of co-production strategy in social service delivery. Out of a total of one thousand and twenty two questionnaires administered to the two categories of respondents, nine hundred and twenty (90 percent) were retrieved. To complement the data extracted from questionnaires, interviews were also conducted with eighteen CDC leaders and nine local government senior staff. The interviews focused, not only on how local government and CBOs delivered social services, but also on the need for collaboration between local government and CBOs in the delivery of social services. With the use of observation techniques, some projects on road, water, electricity, health care and education were surveyed and photographs of some of them were taken. Secondary data were collected from relevant textbooks, government documents and records of social services delivered. The data were analyzed using both descriptive and inferential statistics.
INCORPORATING ENVIRONMENTAL COSTS INTO NIGERIAN OIL AND GAS ACCOUNTING
(2007) AMOS AKINTOLA OWOLABI
This study evaluated the extent of awareness and protective measures by stakeholders of environmental costs in the Nigerian oil and gas industry. It also identified and assessed the environmental factors in the industry that need to be accounted for. These efforts were with a view to developing an accounting model for measuring environmental costs in the industry. Data were obtained through two sets of questionnaire survey. The first set evaluated the extent of awareness and protection measures of environmental costs in the oil and gas industry using a 5- point Likert scale. The second set focused on the identification, assessment and evaluation of the perceived impacts of environmental factors by stakeholders in the oil and gas industry. Forty-two environmental variables obtained from literature and confirmed by experts in the industry were included in the survey questionnaire. Out of a population of 3,200; 540 respondents were selected through stratified purposive sampling from the relevant stakeholder groups. These included accountants, engineers, scientists, health officers, environmentalists and other managers from the five upstream and eight downstream oil companies, one state ministry of environment from each of the eight oil producing states, Federal Ministry of Environment, oil community, oil services companies, Nigerian National Petroleum Corporation, Department of Petroleum Resources and Non-Governmental Organizations. Data from the survey were subjected to descriptive and inferential statistical analyses/secondary data on estimates of revenue and costs associated with recently completed/on-going oil sites were obtained from the records of the stakeholders. These constituted the input data set used in developing the accounting model. In addition to this data set, the forty-two environmental variables identified in the second questionnaire were parsimoniously reduced to a five-factor solution using factor analysis. The results of the study indicated that the respondents demonstrated a high degree of awareness of environmental issues in the industry (overall mean rating of 4.41 out of a maximum of 5.00 on a Likert scale) and a positive attitude towards environmental costs and liabilities (overall mean rating of 3.51). From the forty-two environmental variables, a five-factor solution with their factor loading was obtained from the factor analysis. These were: XI = 'impact on public health (7.95%)', X2 = `occupational health impact (39.04%)', X3 = `impact on agricultural produce (3.24%)', X4 = `marine and fresh water impact (5.5%)', and X5 = `building and infrastructural materials (11.07%)'. These five factors were employed to develop a multi linear regression accounting model: S = 1758.4325 + 3.9460496X1 – 28.07389X2 + 7.3036634X3 + 0.5642708X4 + 23.019651X5, where, S was revenue and X was costs. The developed model was later validated using 10 sets of virgin data. The result indicated low percentage deviation of the model from the actual values (largely within ± 15%). Also the standard measures of accuracy of the regression model were high (R2 = 0.937; F = 86.8; P < 0.05) suggesting its high predictive ability. In conclusion, the study showed that there was a high degree of awareness to environmental issues and a positive attitude towards environmental costs and liabilities in the Nigerian oil and gas industry. The result also concluded that environmental costs could be incorporated into a revenue accounting model.

(2007) BALA, HALIRU
The study identified the socio-economic tenets and injunctions of Shari'ah that regulate the production and marketing practices and appraised their effects on production practices, with a view to determining the extent to which they affect the development of marketing promotion strategies in Northwestern Nigeria. The study was conducted in Northwestern Nigeria, namely in Jigawa, Kaduna, Kano, Katsina, Kebbi, Sokoto and Zamfara States; purposively selected to reflect the core of Shari'ah States. The data were gathered using primary and secondary sources. Multi stage and random sampling techniques were used in selecting 1,392 respondents for the study (180 management staff, 460 traders, 692 consumers and 60 staff of production section) out of 2,000,915. Questionnaires were used to elicit information and were validated by experts in the Shari'ah Law, Arabic and Islamic Studies. The data generated from the survey were subjected to both descriptive and inferential analyses. The findings revealed a significant relationship (r = 0.872; P < 0.001) between Shari'ah socio-economic tenets and injunctions on marketing practices. A significant relationship (r = 0.502; p<0.001) was also revealed between Shari'ah socio-economic tenets and injunctions and production practices. The study further showed that there was a significant positive correlation (r = 0.731; P < 0.001) between Shari'ah Socio-economic tenets and injunctions and marketing promotion strategies. The study concluded that Shari'ah socio-economic tenets and injunctions have influence on production and marketing practices, in particular the marketing promotion strategies.

(2008) ADESOPO, AYO ARIYO
This study examined the origin and development of inter-governmental fiscal relations (IGFR) in Nigeria as well as their linkages with the political arrangement. It also identified and analysed the effects of these linkages on the states and local governments and synthesized the perception of IGFR by selected states. This was with a view to providing insights into the dynamics, management and problems of IGFR in Nigeria. Primary and secondary data were used for the study. A questionnaire was administered on top career officers of the relevant government departments/parastatals at both the state and local government levels in 6 purposively selected states (Benue, Bauchi, Kaduna, Enugu, Delta and Ondo) representing each of the geo-political zones in Nigeria. Of the 312 copies of questionnaire administered, 251 (79.8 per cent) were retrieved. To complement the data collected from questionnaire, interviews were also conducted with 18 top political functionaries at the local government level, 3 of the commissioners representing the selected states on the National Revenue Mobilization, Allocation and Fiscal Commission (NRMAFC) and 19 opinion leaders comprising political elites knowledgeable about political and economic issues in the zones. The interviews focused on the sharing of the Federation Account among the vertical organs, the appropriateness of the revenue sharing principles in use for horizontal sharing and the distribution of tax jurisdiction. Secondary data were obtained from relevant textbooks, journals, newspapers, and official publications of the Central Bank of Nigeria (CBN), Federal Ministry of Finance, NRMAFC and other relevant publications. Data were analysed by means of descriptive and inferential statistics.

(2016) AJAO MAYOWA GABRIEL
The study identified human resource management practices in use in the agro-allied sector in Nigeria, and determined the extent to which different human resource management practices influence different measures of organizational performance in the agro-allied sector of the country. It also examined the problems encountered in the application of different human resource management practices by firms in the agro-allied sector of the economy. These were with a view to providing information on human resource management practices that enhance organizational performance. The study made use of primary data through the administration of questionnaire. The population for the study consisted of 1,406 permanent staff of the five agro-allied companies (Livestock Plc; Okomu oil palm Plc; Presco Plc; FTN Cocoa Plc and Ellah Lakes Plc) quoted on the Nigerian Stock Exchange. A sample size of 311 staff was selected using the Serakan (1992) formula for sample size determination. Based on proportional representation of number of staff in each company, the sample size was allocated to the five companies. Data collected were analyzed using mean, z-test and t-test. The study results showed that training and development (̅X = 4.61, Z=33.49); performance appraisal ( X̅ = 4.56, Z = 31.29); recruitment and selection ( X̅ = 2.85, Z = -1.74); and compensation and reward management (̅X = 2.43, Z = -9.42) were the human resource management practices in use by firms in the agro-allied sector. The results further showed that there is statistically significant positive relationship between human resource management practices and different measures of organizational performance such as: effectiveness (t = 7.99, p < 0.05); efficiency (t = 13.34, p < 0.05); development (t = 2.89, p < 0.05); and quality (t = 1.53, p < 0.05). Furthermore, the results revealed that lack of competitive and performance based compensation packages by management ( X̅ = 4.23) and low level of organizational commitment by employees ( X̅ = 4.14) were the prominent problems encountered in the application of human resource management practices by firms in the agro-allied sector. The study concluded that human resource management practices directly and significantly influenced organizational performance in the agro-allied industry in Nigeria

(2019) PHILIP OLAWALE ODEWOLE
The study appraised the contents of financial reforms in public sector entities and investigated the level of compliance with the financial reforms in public sector entities. It also analysed the trend of the internally generated revenue and assessed the efficiency of public sector entities in the utilisation of financial releases. Finally, the study evaluated the financial sustainability of the public sector entities in Nigeria. These were with a view to providing information on the level of compliance and the efficiency of financial reforms of public sector entities in Nigeria between 2009 and 2016. The study employed both primary and secondary data. The population of the study for both primary and secondary analysis consists of 98 Federal Ministries, Departments and Agencies (MDAs). Two Ministries were selected for the study using purposive sampling technique; namely Ministries of Health and Education. Purposive sampling technique was used to select 50 MDAs whose data on relevant information are readily available and accessible. Primary data were sourced with the aid of structured questionnaire administered to 500 accountants and auditors in the selected MDAs. Secondary data on variables such as capital releases, overhead releases, personnel cost releases and the internally generated revenue were sourced from the Annual Warrants to the MDAs by the Federal Ministry of Finance and the Annual Reports of the Office of the Accountant General of the Federation together with the Audited Financial Statements. Data were analysed using content analysis, percentage, efficiency score, factor analysis technique, Data Envelopment Analysis (DEA) technique and Balance Score Card (BSC) method. The results showed that the contents of the financial reforms were not home-grown and therefore did not reflect the peculiarities of Nigerian Public Sector entities’ domestic operations. The results revealed 55% compliance with the budget reform, 22% compliance level with the adoption and implementation of the International Public Sector Accounting Standards (IPSAS), 44.3% compliance with the implementation of Integrated Personnel Payroll and Information System (IPPIS) among the MDAs while the results of compliance with the Treasury Single Account recorded 60.6% and 55.5% with GIFMIS. Also, the results of the trend analysis of internally generated revenues showed that there was a spike of IGR among the MDAs in year 2016 as a result of the cash management reform. Furthermore, results showed that Decision Making Units (DMUs) under both Health and Education sectors were marginally inefficient in the utilisation of personnel cost releases with the overall average efficiency scores of 82.3% and 82.7% respectively. Also, the results also showed that the DMUs under the two sectors were distinctively inefficient in capital grants allocation with overall average efficiency scores of 53.3% and 54.5% for education and health sector respectively while the overall average efficiency scores in the utilisation of overhead cost releases showed that DMUs under health sector are more efficient than their counterparts under education with the efficiency scores 97.9% and 89.0% respectively. In summary, none of the DMUs attained a full efficiency of 100% during the research period. Lastly, the results of the findings on financial sustainability of the public sector entities revealed that MDAs under the education sector were more financially sustainable than their counterpart under health sector. The study concluded that none of the public sector entities in Nigeria fully complied with the financial reforms and did not attain full efficiency between 2009 and 2016

(2019) ADESANMI TIMOTHY ADEGBAYIBI
The study analysed the trend and pattern of intellectual capital among quoted non-financial companies in Nigeria and evaluated the extent of corporate governance practices among quoted non-financial companies in Nigeria. It also examined the effect of intellectual capital on performance measures of quoted non-financial companies in Nigeria and investigated the moderating role of corporate governance on the relationship between intellectual capital and performance. These were with a view to providing information on the extent to which corporate governance strengthens the relationship between intellectual capital investment and financial performance of firms in Nigeria. Secondary data were employed for this study. Purposive sampling technique was used to select a sample of 50 companies out of the total population of 80 non-financial quoted companies whose stocks were actively traded on the Nigerian Stock Exchange for the period of 2007 to 2017 and whose data on relevant information were readily available and accessible. The choice of base year 2007 was informed by global economic recession that affected the financial performance of quoted non-financial companies in Nigeria. Data on intellectual capital and corporate governance such as human capital, structural capital, capital employed, board characteristics, ownership structure and firms’ economic data were sourced from the audited financial statements of sampled companies. Data collected were analysed using tables, percentages, content analysis and regression analysis. The results revealed that the trend and pattern of intellectual capital among quoted non-financial companies in Nigeria vary ranging from -1.59 (Human Capital Efficiency), -0.81 (Structural Capital Efficiency) and -11.40 (Capital Employed Efficiency) to 428.43 (Human Capital Efficiency), 343.51(Structural Capital Efficiency) and 151.5 (Capital Employed Efficiency) across sectors and period. The result also showed that the extent of corporate governance practices among quoted non-financial companies in Nigeria as at 2017 was low at an average of 34.84%. Furthermore, the result revealed that human capital efficiency (t = 3.1319, p < 0.05), capital employed efficiency (t = 6.7011, p < 0.05), firm size (t = 2.2177, p < 0.05) had significant effect on return on equity while capital employed efficiency (t = 13.5989, p < 0.05) and leverage (t = 4.7112, p < 0.05) had significant effect on return on assets. Finally, the result showed that human capital efficiency (t = 2.1617, p < 0.05), structural capital efficiency (t = 2.3288, p < 0.05), capital employed efficiency (t =12.9183, p < 0.05) and leverage (t = 2.5309, p < 0.05) had significant effects on return on assets while corporate governance had moderating effect on the relationships between intellectual capital and the firm performance through the capital employed efficiency (t = 2.7389, p < 0.05), human capital efficiency (t = 2.2293, p < 0.05) and structural capital efficiency (t = 2.1051, p < 0.05). The study concluded that corporate governance moderated the effect of investment in intellectual capital on financial performance in Nigeria.

(2019) JOHN AYOBAMIBO OLAYIWOLA
The study examined the trend and pattern of corporate dividend from 2001 to 2016, assessed the factors influencing corporate dividend pay-out policy of quoted Nigerian companies and investigated the long run and short run effects of corporate dividend policy on corporate performance of quoted companies in Nigeria over the study period. It also analysed the dynamic relationships among dividend payout policy, investment behaviour and corporate value of quoted companies and examined the interactive effects of dividend pay-out policy and firms’ investments on corporate value of listed companies in Nigeria. These were with the view to providing information on the relevance of dividend pay-out for policy formulation and implementation in enhancing investment decisions and performance of quoted companies in Nigeria. The study employed secondary source of data collection. A sample of 80 quoted companies out of 227 listed companies in Nigeria were purposively selected based on availability of required information in their annual reports and the existence of the companies over a period of 2001-2016. Year 2001 was chosen as base year because that was the third year in which democracy was restored in Nigeria and during this period, various economic policies and reforms were made by the government that affected the activities and operations of quoted companies in Nigeria. Secondary data on firms’ age, property, plant and equipment, dividend per share, dividend pay-out, agency cost, return on equity, return on total assets, leverage, price-earnings ratio and share price were all obtained from the audited Annual Reports of the selected companies and the fact book published by Nigeria Stock Exchange. Data on gross domestic products, inflation, exchange rate and capital were obtained from the World Bank. Indicator and statistical bulletin published by Central Bank of Nigeria, while oil price was sourced from Organisation for Petroleum and Exporting Countries’ annual oil price statistics. Corruption index and legal system index were also obtained from International Country Risk Guide published by World Bank. Data collected were analyzed using percentages, generalized method of moments, autoregressive distributed lag and structural vector autoregression (SVAR). The results showed that the trend of dividend pay-out of quoted companies in Nigeria was increasing at a diminishing rate as the pattern of dividend payout showed 7.9% increase in year 2001 and finally stood at (-5%) in year 2016, that is, increasing by 10% when compared to year 2010. Results further revealed that GDP (t = 58.56; p < 0.05), GFCF (t = 35.768; p < 0.01), Inflation (t = 72.67; p < 0.05), Oil (t = 12.218; p < 0.05), Legal (t = 48.94; p < 0.05) and lag of DPS (t = 48.94; p < 0.05) all wielded positive and significant impact on dividend policy, while other variables exercise a negative but significant influence on corporate dividend policy of Nigerian companies. In addition, results also revealed that dividend policy negatively and significantly influences performance of companies in the short run (t = 10.76547; p < 0.05), while in the long run, the impact of dividend policy was positive and also significant (t = 2.94924; p < 0.05). Results of the SVAR estimates showed that the response of firms’ investment to shocks in the market value was 1.98% in the 10th period of the forecast horizon while that of dividend was 7.04%. Finally, the estimation results revealed that the interactive effect of dividend policy and investment was negative and significant (t = 84.38; p < 0.05) on the measures of corporate performance of quoted Nigerian companies. This study concluded that the responses of investment policy and market value to shocks in dividend policy had contractionary effects and as such could lead to an enhanced investment decision and market values of quoted Nigerian companies.
INTERNATIONAL FINANCIAL REPORTING STANDARDS AND EARNINGS MANAGEMENT AMONG QUOTED NON-FINANCIAL FIRMS IN NIGERIA (2007-2016)
(2019) KOFO AMOS ADEGBOYE
The study analysed the trend of earnings management in listed non-Financial companies in Nigeria from 2007-2016 and examined the determinants of earnings management among selected listed non-Financial companies in Nigeria during the study period. It also assessed the direction of causality between earnings management and quality of accounting information and evaluated the effect of International Financial Reporting Standards (IFRS) implementation on earnings management of Nigerian quoted non-Financial companies during the period. These were with the view to providing an insight on the effect of the mandatory adoption of IFRS on earnings management among quoted non-financial firms in Nigeria between 2007 and 2016. Data were collected from primary and secondary sources. The population consisted of 84 quoted non-financial companies in Nigeria. A sample size of 62 non-Financial firms whose shares were traded during the period 2007 - 2016 were purposively selected based on availability and accessibility of data. Year 2007 was chosen as the base year due to the fact that the global economic recession coupled with the high level of international business competitions became prominent making sustainability of performance elusive for reporting entities. Primary data were sourced through the administration of open and close-ended structured questionnaire. Data on IFRS adoption and earnings management were sourced from annual reports and accounts of companies and from Nigerian Stock Exchange Factbooks. Data were analysed using percentages, pooled ordinary least square, random and fixed effect models as well as granger causality test. The results showed that earnings management witnessed a rising trend in discretionary accrual during the whole ten years` period (2007-2016) from -0.050 in 2007 to 0.036 in 2016 with smallest -0.046 and highest 0.051 in 2012 and 2013 respectively. The results showed that the leverage (r = 0.1150; p < 0.05) and growth (r = 0.006; p < 0.01) were the determinants of earnings management. In addition, the results showed that a bi-directional relationship existed between earnings management (z = 4.860; p < 0.01) and quality of accounting information (z = 4.7976; p < 0.01). Finally, the results revealed that IFRS adoption (r = -0.0616; p > 0.05) showed a negative and insignificant effect on earnings management.

Optimization and modeling of process parameters on the yield of enhanced pyrolysis oil during co-pyrolysis of cassava peel with polystyrene
(2021) Adeboye BS; Adewole BZ; Adedoja AM; Obayopo SO; Asere AA; Kayode O; Idris MO; Okediran IK
The co-pyrolysis of cassava peel (CP) and a synthetic waste, that is polystyrene (PS) has been investigated to optimize the yield of biofuel with improved properties. The main and interaction effects of process variables (temperature, feedstock ratio, and pyrolysis time) on the yield of pyrolysis oil were modeled and the optimal condition for enhanced pyrolysis oil yield was determined using response surface methodology by employing the central composite design matrix. A model equation was generated using the data obtained and the significance of the model was investigated using analysis of variance to determine if the fit of multiple regressions was significant. Some physical properties of the pyrolysis oil at the optimum condition were determined to investigate the suitability of the pyrolysis oil as a fuel source. From the statistical analysis, the study concluded that the feedstock ratio has the most significant effect on the yield of pyrolysis oil.
Influence of health literacy on health promoting behaviour of adolescents with and without obesity
(2021) Adewole KO; Ogunfowokan AA; Olodu M
Background Learning has been associated with human behaviour, and health literacy is vital in an individual’s health promotion and maintenance activities. Purpose This study aimed at comparing the health literacy and health-promoting behaviour of adolescents with and without obesity, and to also identify the association between health literacy and health-promoting behaviour of these two groups of adolescents. Methods A concurrent mixed-method design was adopted and the study was conducted among150 adolescents with obesity and 150 adolescents without obesity from 15 private secondary schools in Osun State, Nigeria. A structured self-administered questionnaire and an in-depth interview guide were used to collect data on their health literacy levels and health-promoting behaviour. Results The findings showed that adolescents without obesity had a higher level of health literacy (70%) compared to their counterparts with obesity (59%). More than half (55.3%) of those with obesity and 35% of those without obesity scored low on health-promoting behaviour scale. Also, there was a significant relationship between health literacy and health-promoting behaviour among adolescents with obesity (r = 0.29; p = 0.001) and those without obesity (r = 0.85, p = 0.015). Conclusion The study concluded that adolescents with obesity had lower level of health-promoting behaviour despite their high level of health literacy, compared to those without obesity. Irrespective of the adolescent’s obesity status, their health-promoting behaviour is significantly associated with their health literacy. Implication for school nursing practice is documented.
Influence of nature of catalyst on biodiesel synthesis via irradiation-aided transesterification of waste cooking oil-honne seed oil blend: Modeling and optimization by Taguchi design method
(2021) Falowo OA; Apanisile OE; Aladelusi AO; Adeleke AE; Oke MA; Enamhanye A; Latinwo LM; Betiku E
Biodiesel synthesis from waste cooking oil (WCO) and honne (Calophyllum inophyllum) seed oil (HSO) blend with heterogeneous (calcined Ba(OH)2 and calcined biomass waste (CBW) from Enterolobium cyclocarpum) and homogeneous (KOH) catalysts via two-step irradiated-transesterification process was evaluated in this study. The modeling and optimization of the two processes were studied using Taguchi orthogonal array technique. The factors considered for the esterification process were methanol/WCO-HSO ratio (10:1–30:1), time (2–8 min), heating power (150–450 W), and H2SO4 dosage (0.5–1.5 wt%). In contrast, the factors considered for the transesterification process were methanol/WCO-HSO ratio (6:1–12:1), time (1–7 min), heating power (150–450 W), and catalyst dosage (1–2.5 wt%). Minimum FFA of 0.50% was attained using methanol/WCO-HSO ratio of 30:1, time of 2 min, heating power of 150 W, and H2SO4 dosage of 1.5 wt%. For the transesterification of WCO-HSO blend, the optimum values are methanol/WCO-HSO ratio of 6:1, time of 1 min, heating power of 450 W, and KOH dosage of 1.75 wt% with a biodiesel yield of 99.4 wt%; methanol/WCO-HSO ratio of 6:1, time of 1 min, heating power of 300 W, and calcined Ba(OH)2 dosage of 1.75 wt% with a biodiesel yield of 98.8 wt%; and methanol/WCO-HSO ratio of 6:1, time of 4 min, heating power of 450 W, and CBW dosage of 1.75 wt% with a biodiesel yield of 100 wt%. The processes catalyzed with synthetic KOH and Ba(OH)2 reached maximum biodiesel yield faster than the crude CBW. The biodiesel quality obtained in this study shows that all three fuels met the American standard specifications and could thus serve as substitutes for fossil diesel.
Investigation into the suitability of well water near cassava processing areas for drinking and irrigation purposes
(2021) Oyewusi TF; Osunbitan JA; Taiwo A
Water used for domestic and irrigation purposes are sometime contaminated by organic and inorganic pollutants from cassava processing centres. Accordingly, groundwater from ten randomly wells were analyzed for pH, turbidity, total suspended solids (TSS), total dissolved solids (TDS), electrical conductivity (EC), sodium adsorption ratio (SAR), CN−, Na+, K+, Ca++, Mg++ and NO3− ion concentrations and the microbial content to determine the suitability of these waters for drinking and/or irrigation purposes. The qualitative analysis reveals that all the ten sites recorded permissible of limits for TDS (<500 mg/l for drinking purposes). Also, all the sites had permissible limits for EC values (<750 dSm−1 recommended for irrigation water) and thus can be used for irrigation with adequate attention on irrigation duration and frequency, drainage and crop species. However, none of the groundwater samples satisfy the World Health Organization (WHO) guidelines of 0.1 mg/l cyanide value and zero coliform bacterial count for drinking water quality and are therefore not recommended for drinking.
Effectiveness of different alpha lattice designs in the evaluation of maize (Zea mays L.) genotypes in a rainforest agro-ecology
(2021) Akinwale RO; Odunlami LK; Eze CE; Oladejo AS
Plant breeding experiments require the use of appropriate experimental designs that will efficiently block variation due to wide heterogeneity nature of tropical soils. The primary objective of this study was to assess the effectiveness of eight different alpha-lattice designs relative to randomized complete block design for evaluating 108 genotypes of maize under rainforest agro-ecology. The maize genotypes were field-tested using three replications at two locations. Data were collected on grain yield and other agronomic traits. Data collected were subjected to analysis of variance (ANOVA) assuming randomized complete block design (RCBD) and eight alpha-lattice designs. Pearson's correlation and stepwise multiple regression analyses were used to analyze relationship among different designs and efficiency of the lattice designs over RCBD was computed. Result showed that all the alpha lattice designs except 27 × 4 were effective in evaluating the genotypes for plant height. There was significant difference (p < 0.001) among genotypes for grain yield only when data were analyzed based on 9 × 12 alpha lattice design. In addition, results showed that the proportion of variation due to blocking and R-square values of the model increased with increase in the number of blocks for grain yield. In contrast, coefficient of variation decreased with increase in the number of blocks. The result showed an increase in efficiency of the alpha lattice designs as the number of blocks increased. It could then be concluded that the more the number of blocks within replicate, the proportion of total variation due to blocking increased, the coefficient of variation (CV) reduced, coefficient of determination (R-square) increased and thus, effectiveness increased. Appropriateness of designs was trait dependent. The 9 × 12 alpha lattice design was identified to be the best in the evaluation of grain yield for the maize genotypes.
