1 O.J Saliu, S.O Ukwuteno and D.O Ekpa 2006 Constraints in the Adoption of improved Palm Technology among Small Scale Farmers in Dekina Local Government Area of Kogi State. Journal of Scientific and Industrial Studies. Vol. 4, Number 3, 2003. Nigeria. Vol. 4 29 -32 CONSTRAINTS IN THE ADOPTION OF IMPROVED OIL PALM TECHNOLOGY AMONG SMALL SCALE FARMERS IN DEKINA LOCAL GOVERNMENT AREA OF KOGI STATE O.J. Saliu, S.O. Ukwuteno and D.O Ekpa Department of Agricultural Economics and Extension Kogi State University, Anyigba. ABSTRACT The environmental suitability of Oil palm in the eastern part of Kogi State motivated the colonial masters to establish an oil palm mill in Gbobe near Lokoja in 1857. This development further encouraged NIFOR to dispose of over 3,000 improved oil palm seedlings to farmers in the area. Some of these farmers discontinued the adoption later while many did not adopt the improved oil palm at all. This work therefore examines the constraints against the adoption of the improved oil palm technology. Stratified random sampling was used to collect information from one hundred and twenty (120) oil palm farmers in the four districts in the study area. Descriptive statistics such as bar chart and pie chart were used to analyze the data collected. Factors such as illiteracy, lack of back up extension support, oil palm seedling pest like termites. Genoderma trunk rot and vascular wilt diseases, cost of inputs and inadequate land for expansion were found to be the major constraints. Agro-service centers. Land reform and reinforcement of extension activities especially education and communications are recommended to reposition the state of oil palm production in Kogi State. Key words: Constraints, Adoption, Oil Palm, Technology.
2 Tiri, G.D., Ekpa, D. and Akinyemi, M. 2015 Empirical assessment of factors affecting marketing efficiency: A focus on sweet orange markets in Kano Metropolis, Nigeria. International Journal of Innovative Agriculture & Biology Research 3(2) 1-9, EMPIRICAL ASSESSMENT OF FACTORS AFFECTING MARKETING EFFICIENCY: A FOCUS ON SWEET ORANGE MARKETS IN KANO METROPOLIS, NIGERIA *TIRI, G.D., *EKPA, D. & AKINYEMI, M. Department of Agricultural Economics and Extension, Federal University Dutsin-Ma, Katsina State, Nigeria *Corresponding author: gtiri@fudutsinma.edu.ng Pnone: +2348035590804 ABSTRACT The study assesses the factors affecting marketing efficiency of sweet orange among wholesalers and retailers in Kano metropolis, Nigeria. A two- stage sampling technique was used in collecting cross sectional data (34wholesaler and 65retailers) by means of well-structured questionnaires used for the study. Descriptive statistics and multiple regression analysis were used to analyze the data. The result from the regression analysis reveals that the ages of the wholesalers and retailers were negatively significant ( P< 0.01) This implies that their marketing efficiency decrease with age . Mode of operation was negatively significant (P<0.05) for both marketer. Part time work decreases the marketing efficiency. Purchase cost was negatively significant (P<0.05). For the wholesaler, the Household size was positively significant (P<0.10). This means that the more the size of the household the more efficient they tend to be. Membership of association was positively significant for the (P<0.10) for the wholesaler and (P<0.05) for the retailer . This implies being a member of the association increases the efficiency of the marketers. The result also shows that the marketing efficiency of Retailers (66.36%) was higher than that of wholesaler (51.70%). The study concludes that retailing outlets are more efficient than wholesaling. Therefore, retailers should be more organised through strong cooperative societies to take advantage of scale economies to maximize profits. In addition to this it was also recommended that improving the deplorable conditions of our roads will reduce the risk of losses and theft and allow cheap flow of fruits from rural to urban centres. The youth should be encouraged through the association to be marketers. Key words: Empirical Assessment, Factors, Marketing Efficiency, Sweet Orange, Kano Metropolis. INTRODUCTION The prominence of sweet orange in nutritional development and overall wellbeing of mankind cannot be underestimated. Sweet orange is an important tree crop that contributes significantly to Nigeria’s Gross Domestic Product (GDP). It is a source of raw material and means of livelihood to rural farmers. The delicious and juicy orange fruit contain an impressive list of essential nutrients, vitamins and minerals for normal growth. Orange juice is used for treating kidney stones (nephrolithiasis) with high cholesterol which prevent high blood pressure, stroke as well as prostate cancer. Fruits act as a putrefying agent by treating body ailment caused by unnatural food intake. Hence, fruit is a natural medicine to man. The pulp can also be used to feed livestock. Sweet orange is one of the most important fruit crops grown all over the world. It belongs to the citrus species which constitute the most important species of the Rutaceae family. Sweet orange constitutes the bulk of citrus fruit production accounting for more than half of the global citrus production in 2004. Sweet orange accounts for approximately 70% of citrus production in Nigeria. In 2010, 68.3 million tonnes of orange were grown worldwide particularly in Brazil and United States of America. It is considered in promoting nutritional security in Nigeria. In West Africa, the major producing areas are Ashanti in Ghana and Oyo state, southern Kwara and Benue State in Nigeria (Anochili, 1986).

1 Ekpa,D.O and Achike, A.I 2012 Climate change effect on cassava processing and marketing in Kogi State, Nigeria. Agricultural Extension Society of Nigeria.(AESON) 17TH 166 -175 Climate Change Effects on Cassava Processing and Marketing in Kogi State, Nigeria Ekpa, D. O and A. I Achike Department of Agricultural Economics University of Nigeria Nsukka Abstract The research work examined the awareness and food security implications of climate change effects on processing and marketing of cassava products in Kogi State, Nigeria. The study sought to: describe the socio economic characteristics of cassava processors/marketers; identify and describe the level of awareness of climate change effects on cassava processing/ marketing technologies; describe the different processing/marketing channels of selected value chains in cassava processing/marketing; and describe the constraints of cassava processing/marketing in the study area. Multistage, purposive and random sampling techniques were used to select 120 cassava processors/marketers that provided the data through a set of structured questionnaire. Descriptive statistics and Mean were employed to analyze data collected. Results of the study showed that, 73% of the respondents were predominantly females. All the farmers were aware of climate change through evidences such as high temperature, late onset of rainfall and heavy wind. Majority (57%) of the respondents experienced more of high temperature compared to other climate change evidence. Majority (58%) of the respondent’s processed cassava to garri and adopted the peeling-washing-grating- dehydration-fermentation-frying processing channel (referred to in the text as processing channel ‘1’). On marketing channels, majorities (70%) were cassava flour marketers and they adopted a marketing channel which comprised of packaging- transportation-wholesaling-retailing and final consumers (referred to in the text as marketing channel ‘1’). The constraint experienced by the respondents includes lack of capital and weather problems. Processed cassava products such as garri, cassava flour and fufu aid food security in Kogi State.

Agricultural Society of Nigeria (ASN) 48TH 42 -45 WILLINGNESS TO PAY FOR EXTENSION SERVICES DELIVERY AMONG CROP FARMERS IN KATSINA STATE, NIGERIA 1 Akinyemi, Mudashiru. 1Ekpa, Daniel and 2Adetunji, Timothy Adewole 1Department of Agricultural Economics & Extension, Federal University, Dutsin-Ma, Katsina State. 2Department of Agricultural Extension, University of Ibadan, Ibadan. Oyo State, Nigeria. Corresponding Author: makinyemi@fudutsinma.edu.ng. +2348068177887 ABSTRACT The study investigates willingness to pay for extension service delivery among crop farmers in Katsina State, Nigeria. Primary data from a cross section of 260 crop farmers through multi stage random-sampling techniques were used .The data were analyzed using descriptive statistics and probit model. The results from the socio-economics of the farmers show that majority of the farmers (76.4%) fall within the productive age of 31-50 years. The crop farmers were male dominated (86.4%). The result from the probit analysis shows that the Age of the farmers was negatively significant (Z= -7.995) on the willingness to pay. This implies that the older the farmer the lesser the likelihood to pay for extension service. Farmer‘s income and proportion of commodity sold were positively significant (Z=21.084). This implies that as the income of the farmers increase the more likelihood they are ready to pay for extension service. Also, as the proportion of the commodity sold increase the more likelihood the farmer pay for the extension service. Land ownership is negatively significant (Z=-2.780), while the household size is negatively significant (Z=-3.382).These indicate that owning a land reduce the likelihood of payment for the extension service delivery. In addition, as the household size increases the likelihood to pay for extension service delivery decrease. The study recommends that efficient machinery should be put in place on marketing of farmer‘s produce. Government should encourage Young people into crop farming
