“…This implies that many farm families take advantage of their large household sizes for increase in production and maximization of profits in their farming enterprise. Onyenweaku and Nwaru (2005), supported this finding Oluwasusi et al 225 that large household size eases labour constraints leading to increase in production. High proportion of the respondents (64.1%) belonged to a co-operative society.…”

“…Stabilisation policies to reduce inflation and subsidies in the form of cheap credit was suggested by Okoye (2006) to assist farmers in acquiring inputs. Onyenweaku and Nwaru (2005) opined the efficient utilisation of productive resources as ways of increasing productivity. This study examined productivity growth, its decomposition and rate of change in food crop production in Imo State in Nigeria.…”

“…The general decline in agricultural productivity has translated into gross incapacitation of the sector in meeting the rising food demand and by extension led to perennial for instance food shortages, soaring food prices and massive importation ( Imodu, 2005;Onyenweaku and Nwaru, 2005). Tanko et al (2006) averred that Nigeria's food deficient situation has been worsened by declining farm productivity owing to inefficient production techniques, poor resource base and declining soil productivity among others.…”

Agriculture plays pivotal roles in Nigeria including food security, employment, foreign exchange earnings and poverty reduction. This study examined the growth in food crop productivity in Imo State in Nigeria with emphasis on the decomposition of total factor productivity (TFP) into technical progress, changes in technical and allocative efficiency and scale effects. A panel data set comprising 210 observations drawn over 2001 -2007 periods was used. Using the translog stochastic frontier production function, the decomposition components were computed. The results showed that TFP decreased through time, while technical change was negative, implying downward shift of the production frontier. As a major component, technical change was the main constraint to the achievement of high levels of TFP during the study period. The scale effect, which is generally bigger than technical change component shows that the sampled farms had not taken advantage of scale economies. Furthermore, the allocative efficiency had an average magnitude closer to the scale effect and points towards decreases in the efficiency with which production factors are allocated. This is an indication of a decline in technical efficiency. We suggest reforms in the Agricultural Development Programmes (ADPs) geared towards enhancing their capacity in extending novel technologies and innovations to farmers.

“…Survey reports in Nigeria show that production, marketing and utilization have expanded in the last decades beyond its traditional central and riverine areas (Agboola, 1979) to almost all ecological zones in the country (Teweet al, 2001). The crops are grown for both human and animal consumption (Onwueme, 1978;Onwueme and Sinha,1991;Onyenweaku and Nwaru, 2005). Household income is also supplemented by sales of the root tubers in local markets and to urban dwellers (Woolfe, 1992).…”

The study investigated the socio-economic factors affecting potato consumption among households in Odeda Local Government Area (LGA), Ogun State. Multistage sampling technique was used to gather information from 80 households using a structured questionnaire. Data collected were analyzed using descriptive statistics and regression model. The study showed that 67.5 % of the household-heads were male, 42.5 % were less than 30 years old, more than half (53.8 %) had income less than NG₦50,000.00 (US$322.59) monthly while 55 % and 68.8 % spend less than NG₦2,000.00 (US$12.90) on sweet and Irish potato, respectively, on a monthly basis. The linear functional form for sweet potato regression result showed that the total household income and sweet potato market price were both significant at 5 % with the coefficient of determination (R 2 ) being 0.611 while the double-log functional form for Irish potato regression result showed that age of household-head, Irish potato market price and price of substitute (yam) were significant at 5 %, 10 % and 10 %, respectively, with coefficient of determination (R 2 ) being 0.897; and had a positive relationship with potato consumption in the study area. Conclusively, the age of household-head, total monthly income, price of potato and price of substitute were factors that determined consumption of potato in the study area. In order to combat problems of malnutrition and to contribute to improvement in households' welfare in Odeda LGA, efforts should be intensified in ensuring that households have access to adequate quantity of food and promotion of households' education on the nutritional values and human nutrition with respect to age and gender are necessary.
