Relative Technical Efficiency of Cassava Farmers in the Three Agro-Ecological Zones of Edo State, Nigeria
P.O. Erhabor,C.O. Emokaro
Journal of Applied Sciences , 2007,
Abstract: This study employed the use of the Stochastic Frontier Production Function in the comparative economic analysis of the relative technical efficiency of cassava farmers in the three agro-ecological zones of Edo State. A multi-stage random sampling technique was used to select 156 cassava farmers from the three agro-ecological zones of the State and the differences in the results obtained were discussed. The empirical estimates showed individual technical efficiency values that ranged from 23 to 95%, 43 to 97% and 52 to 98% with a mean of 72, 83 and 91%, for Edo South, Edo North and Edo Central agro-ecological zones, respectively. This shows that systemic differences in relative technical efficiency levels exist between the three zones and these differences were shown to be related to particular farmer’s characteristics. Non-physical factors that served as determinants of technical inefficiency in the three zones were, farmers level of education, age, farming experience and variety of planting materials used. Gender and family size were however, not found to be significant determinants of the technical inefficiency of cassava farmers in the State. Apart from this estimates serving as a guide to potential investors in the cassava industry in the State, the relative variations in technical efficiency is also an indication of the gaps that exist in the current production technologies employed by cassava farmers in the three agro-ecological zones of the State. The gaps should serve as intervention points for government and non-governmental agencies as well as other stakeholders in the emerging cassava industry in Nigeria.
Efficiency of Resource-use and Marginal Productivities in Dry Season Amaranth Production in Edo South, Nigeria
C.O. Emokaro,P.A. Ekunwe
Journal of Applied Sciences , 2007,
Abstract: The objective of the study was to determine whether the resources employed in the production process were efficiently utilized. The primary data used in the study were gathered with the help of a well structured questionnaire, administered through the cost-route method of data collection. The simple random sampling technique was adopted after the study area had been stratified into regions where dry season amaranth production is carried out. The underlying analytical techniques employed were multiple regression analysis and descriptive statistics. The result showed that dry season amaranth producers in Edo South are smallholder farmers, predominantly males, with mean farm sizes ranging between 0.046, 0.067 and 0.093 hectare. It was also shown in the study that none of the resources employed in the production process was efficiently utilized. While land and fertilizer were underutilized (with efficiency estimate of 5.57 and 1.78, respectively), labour was shown to be over-utilized (with an efficiency estimate of 0.27). The immediate implication of these findings is that there is enough potential for increased production of amaranth, especially in the dry season when amaranth is known to be scarce. This can be actualized by the cropping of larger hectares, regulated usage of higher quantities of fertilizers and the provision of labour saving machines like water pumps and irrigation devices, which would help reduce labour requirements and enhance efficiency. This would go a long way in addressing the serious nutritional deficiencies in the diets of the average Nigerian.
Sporangiospore-to-yeast conversion: Model for morphogenesis
C.O Omoifo
African Journal of Biotechnology , 2009,
Abstract: This report reviewed the specific characteristics of Mucor circinelloides in solid cultures and its capacity for multiple anamorphic expressions in synthetic broth, including holoblastic, holothallic, enterothallic conidia, and vesicular conidia head group as well as yeast cells. Attempt was made to show that the sequence of events in the conversion process, with inherent cytosolic nucleation and protoplast formation, to terminal budding yeast cell would serve as a model for studying morphogenetic transformation in the fungi.
Beliefs and attitude towards Spectacles
C.O Adeoti
Nigerian Journal of Clinical Practice , 2009,
Abstract: The study was conducted in order to discover the beliefs and attitude of the people towardswearing glasses in order to improve acceptance of glasses when prescribed thus reducing blindness and visual impairment due to uncorrected refractive errors. Across sectional study of 198 participants using a pretested structured questionnaire was conducted during the parent-teacher association (PTA)meeting of three public secondary schools chosen at random from a list of schools in Osogbo. Information obtained included the age, sex, history of using glasses, experience if using glasses,whether or not theywill allowtheirwards to use glasses if prescribed and if no,why theywill not. The data obtained was analyzed using Statistical Package for Social Sciences (SPSS 11.0 version) Computer Software. Association between variables was examined using chi-square and T-test accordingly. Level of significancewas drawn at P<0.05. Themale to female ratio was 1: 1.5. Their ages ranged between 15 and 80 years with amean of 36.20 years (SD ± 13.44). Majority, 141(71.21%) were between 21 and 50 years.All but 4(3.70%) of those that use glasses had good experiences. A significant percentage (38.38%) of the participants will not use glasses if prescribed.One hundred and two (51.52%) participantswill not allowtheir children to use prescribed glasses. Acceptance of glasses for the correction of refractive errors is not encouraging. This is particularly serious when children are concerned. A health education to enlighten the populace about the benefits ofwearing prescribed glasses and the dangers of not using themwhen needed is necessary.
Malocculusion pattern among Handicapped children in Ibadan, Nigeria
C.O Onyeaso
Nigerian Journal of Clinical Practice , 2002,
Abstract: Objective: There is paucity of information in Nigeria concerning the occlusal characteristics of handicapped children, yet they need functional and aesthetic consideration comparable to that of ‘normal' persons. The aim of this study was to investigate the pattern of malocclusion among the handicapped children in Ibadan, Nigeria. Materials and Methods: An epidemiological survey of 412 handicapped children aged 6 – 18 years, 210 males (51%) and 202 females (49%) was carried out. All the children were examined in their classrooms under natural illumination with the assistance of the class teachers and the information obtained such as Angle's classification 12,13,14, overjet based on jackson's method15, overbite and tooth – bone ratio were entered in a pre-structured data form. Result: From the results, normal occlusion was seen in 13.8% children, Angle's class 1 malocclusion in 55.3%, 21.4% had Angle's class II while Angle's class III was seen in 9.5%. One case of Angle's class II div. 2 was seen. Females had statistically significant higher number of class III malocclusion cases (P<0.05). Spacing of the upper labial segment was observed to occur in 51.2% of children examined while spacing of the lower labial segment was noted in 39.6%. Crowding of these segments occurred in 9.2% and 17.7% respectively of the sample population. Overbite I was observed in 54.6% of the children examined. Deep bite (overbite 3) occurred in 2.9% of those examined. Overjet values of less than 2 mm were the most prevalent occurring in 82.3% while 6.3% of the children examined had increased overjet. Conclusion: The pattern of malocclusion among those handicapped children did not vary widely from their ‘normal' counterparts. KEY WORDS: Malocclusion pattern; Handicapped children; Ibadan – Nigeria.

Cassava household expenditure and anthropometric indices of preschool children in rural areas of Imo State
C.O. Asinobi
Journal of Agriculture and Social Research (JASR) , 2003,
Abstract: In an attempt to verify the myth associated with cassava, that high consumption causes malnutrition, anthropometric measurements of 445 preschool children aged 0 - 5 years in 90 randomly selected farm households of cassava growing areas of Imo State were undertaken. Growth deviations (Z – scores) were calculated and assessed from National Centre for Health Statistics (NCHS). Expenditure on cassava and other staple foods was determined for each household of the preschool children and classified into two groups and the average determined. Significance of difference between the mean Z – scores of the children for above and below average expenditure households was determined by Student t – test. The growth deviations were less among preschool children from high than among those from cassava, yam and millet food expenditure households in all the anthropometric indices except in maize expenditure households, but the deviations were significantly less for total food expenditure households. High cassava food expenditure households had higher cash incomes through processed cassava products and hence better nutritional status. In order to maintain good nutritional status total expenditure on all foods rather than expenditure on individual food items as well as more processed cassava products production should be encouraged.

C.O. Olaniyi
Journal of Fisheries International , 2012,
Abstract: The effect of solid state fermentation of Aspergillus niger on millet’s nutritional quality and phytic acid content were investigated in this study. Ammonium sulphate and urea as Nitrogen sources were used in combination with millet at 10 gN kg 1 substrate. The mixture was fermented for 84 h at 35 C and 90-95% RH in the laboratory. The results indicated that the crude protein content of millet was raised from 10.96-17.33%, while the crude lipid was lowered fro 3.12-2.58%. The ash content value was greatly increased from 1.36-7.94%. Five percent changes in minerals (calcium, magnesium and phosphorus) content values were also observed. Phytic acid content value of 0.4 mg 100g 1 reduced significantly to minimal 0.015 mg 100g 1.
The candelabra tree (Euphorbia ingens): a source of water for black rhinoceros in Liwonde National Park, Malawi
C.O. Dudley
Koedoe : African Protected Area Conservation and Science , 1997, DOI: 10.4102/koedoe.v40i1.263
Abstract: The introduction of two rhinoceros into a 15 km2 fenced sanctuary within Liwonde National Park provided an opportunity for close observation of the animals feeding on the toxic succulent Euphorbia ingens. Feeding invariably caused the death of the plant and for plants with basal diameters between 5-17 cm, mortality ranged from 40-90 . During the severe drought of 1994 rhinoceros did not drink from the artificial waterhole from approximately 15 July to at least 23 September. As this waterhole was the only source of free water it is believed that the rhinoceros obtained their water from browsing on E. ingens.

Growth Performance of Finisher Broilers on Livingstone-Potato (Plectranthus esculentus) Tubers Meal
C.O. Okereke
Pakistan Journal of Nutrition , 2012,
Abstract: A feeding trial lasting 42 days was conducted using seventy two (72) 4-weeks old Anak broiler chicks with an average initial live weight of 4.40 kg to determine the growth performance of finisher broilers fed diet containing Livingstone-potato tubers meal. The animals were assigned to four treatment based on their initial live weight. The diets were formulated to be isonitrogenous (20% CP). The control diet was based on maize and soybean meal without Livingstone-potato tubers meal. Feed and water were offered ad libitum. The growth performance of broilers fed on various levels of meals in which Livingstone-potato (Rizga) meal substituted maize at 10%, 20% and 30% showed that there were no significant differences (p<0.05) in final body weight, average daily weight gain, average daily feed intake and feed conversion ratio among the treatments. The implication of these result is that those parameters measured were not significantly (p>0.05) influenced by the dietary levels of Livingstone-potato (Plectranthus esculentus) meal. The results suggest that 30% replacement of maize with Livingstone-potato (Plectranthus esculentus) meal produced no negative effect on the production performance of finisher broilers.
