    (Department of Agricultural Economics and Extension, Nasarawa State University Keffi, 2017-12-12) Onuk, E.G.; Umar, Haruna Suleiman; Girei, A.A.
    The study analyzed broiler production in the Southern Agricultural Zone of Nasarawa State. The study adopted a multi-stage sampling technique to select 60 broiler farmers, primary data on items such as age, gender, level of education, cost of production were collected with the aid of well structured questionnaire and interviewing method. The data were analyzed with descriptive statistics, costs and returns analysis and multiple regression models. The findings revealed that majority (60%) of the broiler farmers were male and 58.3% had tertiary education, 50.0% had 1-5 persons in their households and 36.7% had 6-10years farming experience. It was also revealed from the findings that 50.0% had small flock size between 100-200 birds. The analysis of the costs and returns indicated that the total revenue of broiler farmers was N331, 941.67, the total cost of broiler farmers was N162, 167.99 and the total fixed cost was N12, 344.09. The gross and net farm income were estimated at 182,177.77 and 169,833.61 and net farm income per naira invested of N1.05 which showed that broiler production is profitable. Also, the multiple linear regression showed that F=42.927, R=0.923 and R2 indicated that about 85.2% of the variation in the dependent variable was explained by the independent variables. Age, Level of education, Farming experience, Flock Size were positively correlated with the farmers net farm income involved in broiler production, while gender, marital status and household were negatively correlated. Age was significant at 1%, level of education at 1%, gender at 10% and years of experience in poultry at 10%. However broiler production was constrained by inadequate credit, high cost of day old chicks, and high cost of feed, pest and diseases infestation, lack of electricity among others. Based on the results from the findings of this research It was concluded that broiler production was profitable and showed that broiler production depends to a large extent on proper care and efficiency of the necessary resources to maximize profit. It was recommended that poultry farming should be encouraged among young and educated people, broiler farmers should be granted access to loan facilities, research institutions should provide lasting solutions to menace of pest and disease outbreak and government should provide extension service agents to assist the farmers in the areas of management and technical competency

    CO-INTEGRATION APPROACH TO THE ESTIMATION OF DEMAND EQUATION FOR MALAYSIAN RICE SECTOR
    (Department of Agricultural Economics and Extension, Nasarawa State University Keffi, 2014-01-05) Umar, Haruna Suleiman; Abdullahi, Mahir Amin; Shamsudin, Mad Nasir; Mohammed, Zainal Abidin
    Government policy at achieving self-sufficiency and food security in rice must anchor on understanding structural relationships exist among the major variables in demand side of rice sector. This is because a result-oriented policy decision and implementation depend on the adopted inferences from valid demand elasticities. The validity of estimated coefficients pre- supposes time series data are stationary. Test statistics, like T-test, X2-test and F-test, on which basis inferences are made, depend on this assumption. Some earlier empirical findings about rice demand behaviourmight have suffered spurious regression problem with skeptical inferences because the time series data used did not take cognizance of unit root problems.Hence, this study attempted estimating demand equationby co-integration method. Time series data (1980- 2012) were collected and analyzed using Auto Regressive Distributed Lag (ARDL). For valid inference, estimated coefficients were subjected to necessary diagnostic and unit root tests. The results show that wheat remains a substitute to rice in consumption both in short run and long run. In relation to income per capita, rice can be considered as normal good in the short run; but inferior good in the long run. Rice consumption per capita was inelastic in relation to its price.

    COMPARISON OF DATA ENVELOPMENT AND STOCHASTIC FRONTIER MODELS IN ANALYSIS OF EFFICIENCY AND ITS FACTORS IN GINGER FARMS IN KADUNA STATE, NIGERIA
    (Department of Agricultural Economics and Extension, Nasarawa State University Keffi, 2011-12-12) Umar, Haruna Suleiman; Girei, A.A.; Kachiro, S.L.
    Nigeria is trending below the top ginger producing countries of the world in terms of yield per hectare and national output. Technical Inefficiency due to poor combination and utilization of physical resources in the production of ginger is a major factor for low yield/output. Previous studies employed either Stochastic Frontier Analysis (SFA) or Data Envelopment Analysis (DEA) to measure technical efficiency. So, the question arises as whether the technical efficiency estimates from both methods are similar or not. The present study deployed the two common approaches (SFA and DEA) in estimation of technical efficiency and its determinants in order to ascertain the similarity or otherwise of the estimates. Two hundred and five (205) ginger farmers were randomly sampled for primary data collection. Analyses of the data were done through Descriptive Statistics, DEA, Tobit regression and SFA. The results show that means of the efficiency scores from both models namely DEA (0.70) and SFA (0.88) were significantly different at 1% probability level. However, estimates from both method suggest that the ginger farmers were operating at suboptimal level or below frontier. Also, the results of determinants of efficiency from two estimation methods (SFA and DEA-based Tobit regression) were dissimilar. While SFA method shows that household size, level of education and farming experience were responsible for enhancing the efficiency of ginger farms, none of these variables influenced the farmers’ efficiency under Tobit regression. Therefore, it is recommended that selection of efficiency estimation method between SFA and DEA by the researcher should be based on study objective rather than consideration on the premise of alternative opportunity. Also, greater output level or potential output can be achieved, given the current production technology, by educating ginger farmers on how to ensure that production inputs are combined and managed efficiently.

    COMPETITIVENESS OF TOMATO PRODUCTION IN KOKONA LOCAL GOVERNMENT AREA OF NASARAWA STATE, NIGERIA
    (Department of Agricultural Economics and Extension, Nasarawa State University Keffi, 2018-12-12) Onuk, E.G.; Ibrahim, H.Y.; Umar, Haruna Suleiman
    The study determined the competiveness of Tomato production in Kokona Local Government Area of Nasarawa State, Nigeria. Primary data were collected using a structured questionnaire administered to 60 respondents selected through a simple random sampling technique. Descriptive statistics and Policy Analysis Matrix (PAM) were used for data analysis. The results show that majority (71.7%) of the farmers males with an average of about 8 persons in the household.. The result of the Policy Analysis Matrix (PAM) shows that Tomato production with subsidized inputs is more profitable compared to its production with input purchased directly from the open market. However, the Domestic Resource Cost (DRC) was less than unity, (0.0864) suggesting that tomato production system can be sustainable without government intervention. Major constraints in Tomato production include; lack of basic equipment and infrastructure, inadequate extension service and poor access to credit facilities. Therefore to increase the profit and ensure high return on investment, it is recommended that the state government key into the Fadama III additional Financing project in order to enhance Tomato production.

    OMPARISON OF COBB-DOUGLAS AND TRANSLOG FRONTIER MODELS IN THE ANALYSIS OF TECHNICAL EFFICIENCY IN DRY-SEASON TOMATO PRODUCTION
    (Department of Agricultural Economics and Extension, Nasarawa State University Keffi, 2016-01-05) Umar, Haruna Suleiman; Girei, A.A.; Yakubu, D.
    There has been contradiction among researchers regarding similarity or otherwise of technical efficiency estimate obtained from Cobb-Douglas and Translog frontier models. While some researchers believe that results obtained from the two functional forms, given the same data, were essentially similar, others disagreed. This study compared both functional forms to analyze technical inefficiency in dry-season tomato production in Jos-South Area of Plateau State. Data were collected from 60 dry-season tomato farmers sampled through three-staged random sampling technique. The analyses of the data were done using both Cobb-Douglas and translog frontier models. The results showed that the estimated elasticities, efficiency scores and inefficiency effects from Cobb-Douglas and Translog functional forms differ significantly. Therefore, the choice of functional form for efficiency analysis should be based on convenience, meeting selection criteria premise on the value of variance-parameters and objective of the stud
