Item Optimal transportation and spatial integration of regional palm oil markets in Nigeria(Intemational joumal of operations research and information systems, 2016) Nwauwa, L. O. E.; Adenegan, K. O.; Rahji, M. A. Y.; Awoyemi, T.T."The poor quality of transportation infrastructure in Nigeria impacts negatively on the competitiveness of palm oil. This leads to increased inter-regional transportation cost, delayed time of arrival to the destination and lowered transaction efficiencies in the distribution chains. Primary and secondary data were used. Random sampling technique was used to collect data from 276 distributors in main palm oil markets. Data were analyzed using linear programming and Ravallion model at 0.05 a-level. Results of the data analyzes show that average cost of transporting palm oil from the production market to the consumption market was N5,831.9 per MT. Observed transportation cost was N60,724,830.5 while the optimal cost was N44,003,500.30 indicating a 38.0% reduction in total cost of transportation. Highest optimal allocations to the destination markets were Owerri-Jos (133,500 MT), Ondo-Lagos (107,200 MT) and Port Harcourt-Kano (82,000 MT) at minimum transportation cost of N5,750, N4000.7and N6500.0 per MT respectively. Two lag periods were identified signifying that it takes about 1-2 months for price information to spread across the markets by the model. Six of the 27 market pairs exhibited high short-run market integration for both lag periods with Port Harcourt-Abuja market pail: indicating the highest (0.1 and 0.004). The lowest short-run market integration was recorded in Ondo-Minna market pair indicated by 1.4 and 17.4 respectively. Policies that will enhance redistribution of palm oil supply between producing and consuming regions should be pursued. "Item The determinants of rice farmers’ productivity in Ekiti State, Nigeria(Greener Journal of Agricultural Sciences, 2016) Osanyinlusi, O. I.; Adenegan, K. O.The issue of low productivity of the Nigerian farmers is becoming topical particularly in rice production. Rice is an annual crop and one of the most important staple food crops in Nigeria. Since the mid-1970, the demand for rice has been increasing at a much faster rate in Nigeria than in any other African country. This paper therefore examines the factors affecting rice farmers’ productivity as well as constraints limiting rice production in Ekiti State, Nigeria. Primary data was used for this study with the aid of a well-designed questionnaire to collect data from 160 randomly selected rice farmers. A multi-stage random sampling procedure was used in selecting the respondents. Three major rice-producing Local Government Areas (LGAs) were purposively selected from the State, followed by the random selection of two villages from each LGA. In all, 160 rice farmers were randomly selected from six villages. The objectives were analysed using descriptive statistics, OLS regression and Likert-type scale. The results showed that the linear functional form gave the best line of fit. R2 value was about 77% and statistically significant at 1% level. Farm size, level of education and quantity of fertilizer were positively and significantly related to productivity at 1% and 10% respectively, while years of farming experience and quantity of seeds used were negatively significant at 10% and 1% respectively. Pest infestations and financial constraints were ranked as the most challenging factors limiting rice production in the study area. It is therefore recommended that extension services should be intensified in the area to educate the farmers on the appropriate application rate of fertilizer and seed rate per hectare. In addition, the relevant research institutes should develop a technology for controlling or preventing birds’ infestations in the area.Item Primal-dual links to spatial equilibrium market model for palm oil in Nigeria(International journal of operations research and information systems, 2016) Nwauwa, L. O. E.; Adenegan, K. O.; Rahji, M. A. Y.; Olaniyi, O. Z."Distribution of agricultural produce is undertaken to bridge the gap between production and consumption arising due to spatial separation between areas of surplus and deficit. An investigation of primal-dual links to spatial equilibrium model and integration of palm oil markets in Nigeria was carried out using transportation model. Two-stage sampling technique was used to collect data from 3 markets and 276 distributors. Data were analyzed using linear programing model. Average cost of transportation per mode was bus (N17, 173), truck (N 10,357) and lorry (N5,831 ) respectively. Total transportation cost of N347,809,600.6k was observed compared to a minimized objective cost of NI42,536,800.30k produced by the program. Highest optimal allocation to the destination markets using the different mode of transportation were Port Harcourt-Lagos by lorry (103,200 MT), Owerri- Maiduguri by truck (21,200 MT) and Ondo-Lagos by bus (19,800 MT) respectively. Subsidized cost of public transport facilities will reduce high cost of transportation. "Item Resource use efficiency in commercial poultry production in Oyo State, Nigeria(Tropical animal production investigations, 2015) Musa, R.A.; Adenegan, K. O.Poultry is a major livestock subsector which offers the least expensive way of filling the protein gap in human nutrition. However, low productivity in poultry subsector of livestock industry and inadequate knowledge on efficiency of resource allocation have scared many interested farmers from investing fully in the enterprise. The study ascertained the determinants of poultry productivity and allocative efficiency of each of the major resource inputs in commercial poultry production in Oyo State. Primary data were collected using well structured questionnaires. A multistage sampling technique was used to sample 90 poultry farmers to represent the commercial poultry farmers in the study area. Data collected were analyzed by using descriptive statistics and production function model. The result showed 'that the poultry farmers in the study area were educated and quite experienced in poultry farming with an average of 8years. The number of birds raised, labour, feed and drugs/vaccines were found to be the most significant inputs in poultry production and thus, require special attention. Poultry production in the study area was found in stage two of production surface as indicated by Returns to Scale (RTS) of 0.798. The result further showed that flock size, labour, feed and drugs/vaccines had efficiency indices of 0.046, 0.960, 0.00095 and 0.587 respectively implying that these inputs were inefficiently allocated and utilized except labour that was close to the economic optimum. It is therefore recommended that there should be policies aimed at educating poultry farmers in the study area on efficient resource management techniques most importantly efficient administration of feeds and drugs/vaccines, adequate stocking density of flock and efficient management practices.Item Spatial price analysis of tomatoes in nigeria(International Journal of Management and Marketing Research, 2012) Adenegan, K. O.The study examined market integration in tomato markets in selected producing and consuming states in Nigeria. Secondary data on tomato prices spanning 2003 -2006 were sourced from National Bureau of Statistics. The data were analyzed using Augmented Dicker Fuller (ADF) and Granger Causality tests. Results indicated that the maximum tomato price was recorded in Ekiti in November, 2006 while the minimum price was recorded in Kano state in August, 2006. The results also revealed that prices of tomato were not stationary in their level form but become stationary at the first difference lever Seven tomato markets rejected their respective null hypothesis of no granger causality. None of the markets exhibited bi -directional granger causality or simultaneous feedback relationships Seven markets exhibited unidirectional granger causality. The results also indicated that Ekiti and Katsina states occupy the leadership position in tomato price formation and transmission. We recommend there should be efficient flow of information and good access road and infrastructural development among the states to improve market performance.Item Price transmission and market integration of fish in Oyo State(Journal of Rural Economics and Development, 2010) Adenegan, K. O.; Bolarinwa, A. O.This study examined degree of market integration and price transmission between four categories (local fresh, local dried, imported iced and imported dried) of fish market in the rural and urban area of Oyo State. Secondary data were sourced on the monthly retail prices of fishes for sixty months from the Oyo State Agricultural Development Project (OYSADEP). Data were analysed using the Augmented Dickey Fuller (ADF) test, Granger-causality test and Index of Market Concentration. The result revealed that while the other three market pairs were well integrated, the rural and urban local fresh fish market were not well integrated as the pair accept the null hypothesis of no integration, prices of the local and urban fresh fish market were not tied together in the long run. Thirty-one market links rejected the null hypothesis of no granger causality; seventeen market links exhibit a uni-directional granger causality while fourteen market links exhibit a bi-directional granger causality. The urban fresh fish market occupies the leadership position in the price formation and transmission in the markets investigated. The Index of market connection (IMC) indicates that the markets exhibit low short run market integration. It is therefore recommended that there is need for a policy to ensure efficient marketing of fresh fish in the urban and rural area of the State.Item Productivity of women farmers in the derived savannah zone of Nigeria:Panacea to food crisis(Journal of Research in Agriculture, 2010) Yusuf, T. M.; Okunmadewa, F. Y.; Adenegan, K. O.; Oyekale, A. S."There is food crisis in Nigeria. Food supply can no longer meet up with food demand. Since Women Farmers are the major food producers in Nigeria, it implies that their productivity is significantly low. This study therefore, explored the potential for improving productivity of women farmers in the Derived Savannah Zone of Nigeria. Primary data were collected using multi-stage random sampling technique. Kogi and Kwara states were randomly selected from the six states in the zone. Following this was a random selection of two ADP administrative zones from each slate. A random selection of four LGAs was then made, one from each ADP stratum from which four villages were selected per LGA. In the final stage 200 respondents were randomly selected from the villages on the basis of probability proportionate to size. Data were collected on socio-economic and demographic characteristics, institutional factors, quantities and prices of inputs and outputs. Data were analysed using Descriptive Statistics, Total Factor Productivity Analysis (IFP), and Ordinary Least Squares Regression (OLS) Analysis. The mean age and farming experience of the women farmers were 47.6 ± 9.5 and 20.4± 12.3years respectively. Their mean farm size and number of plots cultivated were 1.8 ± 1.18 acres and 2.0 ± 0.84 respectively. Total factor productivity index ranged from 2.7 to 1,J 04.6 with a mean of 489.9 indicating low productivity level. Factors found contributing to low productivity include; year of farming .extension and land fragmentation. A unit increase in years of education and MEO would increase productivity level by 0.8872 (p<0.01) and 0.1061 (pItem Credit utilisation among rice farmers in Oyo state, Nigeria(Journal of sustainable development, 2010) Oladokun, Y. O. M.; Adenegan, K. O.Assessment has to be made: (ii) assessment of a bank's performance involves both quantitative and qualitative factors; (iii) there is the problem of identifying banks' inputs and outputs; and (iv) the existence of several heterogeneous ,inputs and outputs. That cannot be easily compared. The study makes use of Data Envelopment Analysis in an attempt to measure the relative efficiency of commercial banks. It was observed that inefficiencies link more to inefficient resource utilisation rather than production scale. Also, Nigerian Banks were noted to be highly operationally inefficient. Hence, it is not sufficient to increase the capital base but it is important to make the environment more competitive, and to improve the absolute efficiency of the industry.Item Evaluating relative efficiency of insured banks in Nigeria(Journal of banking, 2010) Fadiran, T.P.; Ogwumike, F. O.; Adenegan, K. O.High level of relative inefficiency among insured banks in the country has serious implications in that the relatively inefficient banks may pose additional risk to the systems safety net. Also, other sectors of the economy may continue to pay for the banking systems inefficiency through high lending rates; Assessment of banks' performance poses some difficulties which include: (i) the nature of bank objectives which are often conflicting and against which anItem Food security among cocoa farming households of Ondo State, Nigeria(APRN Journal of Agricultural and Biological Science, 2009) Oluyole, K. A.; Oni, O. A.; Omonona, B. T.; Adenegan, K. O."In Nigeria, it has been documented that cocoa farmers devote most of their resources toward cocoa production at the detriment of food crop production because they derive more income from cocoa. There is, however, a dearth of information about the consequence of this practice on the food security status of cocoa farming households. In this study, the food security status of cocoa farming households of Ondo State, Nigeria was examined. Multistage sampling technique was used to select 200 respondent households from the study area in 2007. Information was collected from the respondents with the aid of structured questionnaire and the data obtained from the information were analyzed using Descriptive statistics, Food Security Index, Surplus/Shortfall Index and Probit model. The food security line was N2500.50 per month per adult equivalent. Based on this, 43% of the total sampled households were food secure while 57% were food insecure. Food secure households exceeded the calorie requirements by 12% while food insecure households fell short of calorie requirements by 9%. A unit increase in farming experience of household head (p<0.05), output of roots and tubers (p<0.05), output of cereals (p<0.05) and output of cocoa (p<0.01) increases the probability of household to be food secure by 0.0088, 0.00021, 0.000087 and 0.00049, respectively while a unit increase in household size (p<0.01) and age square of household head (p<0.1) decreases the probability of household to be food secure by 0.23 and 0.000074, respectively. A high percentage of households was food insecure, hence, cocoa farming households in the study area could be said to be food insecure "
