Assessment of Anti-Nutrient and Vitamin Compositions of Pleurotus Ostreatus Cultivated on three Waste Materials

Abstract: Studies on the assessment of anti-nutrient and vitamin compositions of Pleurotus ostreatus cultivated on three agrowastes materials were carried out in Dilomat Farms and Services Limited and Department of Plant Science and Biotechnology, Rivers State University. Ten treatments were obtained from the mixtures of cassava bran, wood ash and sawdust at different concentrations which also comprised the control and combined effect. Vitamins assessed were Vitamins A, C, Thiamine and Niacin. The combined effect (CE) had the highest contents of these vitamins investigated. However, minimal concentrations of Vitamin C was recorded. The anti-nutrient analysis showed that the CE treatment had the highest values of phytate (1.95±0.00), oxalate (0.71±0.02) and flavonoid (3.52±0.03). Although, the highest values of tannin (7.20±0.00) and polyphenol (2.50±0.00) were recorded for sawdust and cassava bran (SCB) treatment. The highest concentration of saponin (0.08±0.00) was observed for sawdust and wood ash (SWA) treatment than others. Nevertheless, there was no fruit recorded for higher concentrations of SCB treatment due to contamination. The cyanide concentrations (0.03±0.02 to 0.52±0.01) for treatments containing cassava bran were all within the acceptable limit. Generally, the combined effect treatment performed better than every other treatment utilized.

Assessment of Climate Change on Sesame Cultivation in Makurdi Local Government Area of Benue State, Nigeria

Abstract: . The study was conducted to determine the assessment of climate change and ascertain the awareness among sesame farmers in Makurdi local government area of Benue state. A sample of 120 farmers participated in the study. Descriptive statistics and logit regression were used to analyse the data. The results shows that more male farmers (69.2%) within the age range of 21-40 years are involved in the production of sesame when compared to female farmers (30.8%). It was observed that most of the farmers are married (82.5%). The educational level is low among sesame farmers with most of them having only primary education (45%). The result also shows that most of the farmers have farming experience of less than 10years with a farm size of less than 4 hectares. Insect infestation, soil erosion is perceived as reasons for low yield. Sesame farmers have adapted to such changes through the use of improved seed varieties, use of chemicals and mixed cropping. Results also showed that extension agents, educated farmers and relatives were the major sources of information about climate change. It was also revealed that climate has little effect on sesame as the average yield of the crop is 57.5% compared to low yield of 13.3%, also socio-economic characteristics of the farmers do not have any significant effect on the awareness of climate change as only household size and age are statistically significant at 1% and 5% respectively. To improve farmers’ awareness on climate change, the study recommends that there should be improvement in newspaper and radio/television broadcast in other to sustain sesame production in the event of climate change.

Multidimensional Ethical Dilemmas of Contemporary Organizations: A Literature Review

Abstract: This paper reviewed the literature on ethics, ethical theories, ethical principles; as well as the implications of unethical practices in organizations. The study revealed that unethical business practices have devastating consequences on organizations; since they result in poor corporate image, financial losses; market failures and sometimes complete corporate collapse. It was further observed that corruption, bad leadership, poor corporate governance, conflict of interest, lack of accountability, inadequate CSR, abusive and intimating behaviors among others are common in most organizations. The paper concludes that it is beneficial and in the enlightened self -interest of organizations to adopt good ethical practices. The paper also recommends that managers’ should ensure that ethical standards are crafted in their business philosophy and strategic intents in order to build and maintain a good corporate image.

Work Socialization and Workplace Conflict in Major Oil Companies in Nigeria

Abstract: This study investigated the relationship between work socialization and workplace conflict in major oil companies in Nigeria. The study adopted a cross-sectional survey in its investigation of the variables. Primary data was generated through the self-administered questionnaire. The population for the study was two hundred and fifty-three (253) employees of seven (7) selected manufacturing companies in Port Harcourt. A total of 7 major multinational oil companies were investigated. 35 administrative management staff were sampled using the stratified sampling technique. The spearman correlation statistic was used in testing the hypotheses formulated. The reliability of the instrument was achieved by the use of the Cronbach Alpha coefficient with all the items scoring above 0.70. The hypotheses were tested using the Spearman’s Rank Order Correlation Coefficient with the aid of Statistical Package for Social Sciences version 23.0. The tests were carried out at a 95% confidence interval and a 0.05 level of significance. Results from analysis of data revealed that socialization had both significant and negative influence on interpersonal, intrapersonal, inter-group and intra-group conflicts. The study recommends that socialization should be part and parcel of Original Research Article Sotonye et al.; AJEBA, 21(5): 47-57, 2021; Article no.AJEBA.65258 48 organizational fabric to attain great heights in terms of workforce cooperation which eliminates workplace conflict; and multinational oil companies should develop means to have a well-defined employee-oriented culture as this will boost socio-cultural diversity management within the employees and as such lead to constructive workplace conflict and harmony.

Deep stacking poultry litter as feed ingredient in livestock production

Abstract: The compelling need to harness the potentials of the numerous agro-industrial by-products and the so-called “wastes” as part replacement for the more expensive conventional feed ingredients have been seriously expressed. This need has arisen mainly from the increasing demand and supply deficit of conventional feed resources with a concomitant sharp rise in their cost prices. The net effect of increased unit cost of the conventional feed resources is increased cost of the compounded rations, which by extension gives rise to increased cost of meat and animal products. It then becomes highly imperative that other sources for rapid livestock output to meet the growing human demands for animal protein foods are sourced. Such other sources should be cheap and nutritionally adequate for feeding animals with the aim of lowering the cost of producing meat. One of such measure is the recycling of poultry litter as part replacement for soya bean in livestock nutrition. Poultry litter is the by-product of poultry pro...
