Thus, this study examined the factors responsible for the high level of food insecurity status among female headed households in Nigeria. Secondary data obtained from Harmonized Nigeria Living Standard Survey (HNLSS) conducted by the National Bureau of Statistics (NBS) was used for the study. Information from four thousand nine hundred and seventy nine (4,979) households was used for this study. The analytical techniques adopted include descriptive statistics, Foster Greer and Thorbeck and Tobit Regression Model. The results showed that most of the female headed households’ ages lie within the range 18-60 years and 66.62% of the household were predominantly in the rural sectors. Findings revealed that 59.1% of female headed households are food insecure. Identified determinants of food insecurity among female headed households include: age of household head, household size, g...

Empirical studies have always indicated strong linkage between value addition and enhanced farmers‟ income. The study analyzed Competitiveness and effect of government policies on Plantain Flour and Chips processing in Southwestern Nigeria. A total of 100 processors were sampled; data were analyzed using Policy Analysis Matrix. Result indicated that plantain chips and flour processing had positive private and social profit indicating that processing of the commodities was economically profitable under existing government policies. Result of the Protection coefficients showed that the prevailing incentive structure affected processors negatively. Sensitivity analysis result indicated that policy indicators were sensitive to changes in exchange rate and world price of the products. The study recommends the need for provision of incentives to processors to enhance competitiveness of the commodi...

There are a number of empirical studies on the economics of production of the commodity, but there is insufficient information on marketing of the commodity. The study was therefore carried out to examine market performance, structure and constraints in cucumber marketing. Primary data was collected from 70 randomly selected actors in the supply chain (54 Retailers and 16 wholesalers). Data collected was analyzed using descriptive statistics, net marketing margin, efficiency and Gini coefficient. Findings revealed that most of the retailers (70.4%) and wholesalers (81.3%) were male. Most of the retailers were within 31–40 years whereas majority of the wholesalers were within 41–50 years and all the marketers had secondary level of education (47.2%). Cucumber marketing was profitable at the wholesale and retail level both at the peak and lean season of cucumber production. Retailers sell an average of 159.8 kg an...

To promote vegetables' contribution to the above, there is a need for sustainable and efficient production process. The paper reviewed production, socioeconomic factors, and constraint affecting efficiency of production of three important vegetables (tomato, pepper, and onion). The review showed that socioeconomic factors found to increase technical efficiency in vegetable production were educational level, extension contact, and household size. Influence of farmer age on technical efficiency was inconclusive due to varied opinions. Increase in farm size, quantity of seed, amount of fertilizer, and agrochemical were found to have positive influence on output. Majority of the literature reviewed opined that increase in quantity of labour raises productivity; however, it must be utilized efficiently. The mean technical efficiency of the vegetables varied from the southern to the northern part of the country. The cross cutting constraints in vegetables production are pest and diseases, inadequate storage facilities, and high cost of improved inputs. The study recommends increase awareness and sensitization on optimum levels of resource use for increased productivity and appropriate intervention to constraints in the value chain.

The experiment was arranged in a randomized complete block design (RCBD) with three (3) replicates. The treatments comprised intercropping okra with groundnut or cowpea planted at varying spacings (60 cm x 30 cm, 60 cm x 40 cm, 60 cm x 50 cm and 60 cm x 60cm). Okra was planted at a spacing of 60 cm x 40 cm, the plot size was 3 m x 2.4 m (7.4 m2). Data collected was subjected to analysis of variance (ANOVA) and significant means were separated using the least significant difference (LSD) test at the 5% probability level. Economic analysis of the cropping mixture was carried out using gross margin analysis, monetary advantage index and benefit to cost ratio analysis. Results revealed that the land equivalent ra...

The objective of the study was to Map Plantain Value Chain in order to identify the key players, their roles, value added along the chain as well as constraints. Personal Interview and Focus group discussions were used to collect primary data from the actors along the chain. Data were analyzed using descriptive statistics and Value added analysis. The study identified conventional and peculiar actors such as Input suppliers, Producers, Farm-Gate Assemblers, Market-Arena Assemblers, Insitu Wholesalers, Transit Wholesalers, Processors, Retailers and Consumers. The study revealed tremendous dominance of the Midstream sector in the commodity value chain and that Value addition, volume of trade and geographical coverage indices were highest at the midstream sector. The result revealed also that Plantains were traded mostly in unprocessed form and there was low level of export of the commodity. Producers sold most of their product (55%) at the farm gate. Horizontal flow of the commodity was prominent among the actors. Value added at processing level was estimated at ₦111/kg of processed product. The cross cutting constraints among the actors were inadequate credit accessibility, high transportation cost, inadequate market access and inadequate storage facilities amongst others. The study recommends intervention in the area of linking actors in the value chain to prospective markets for them to benefit from the various activities.

Its profile is rising due to widespread knowledge of its inherent health benefits. To sustain the availability of the crop in order to meet increasing demand, there is the need to enhance its productivity. Crop productivity depends on the efficient use of both material and human resources utilized in the production process. This study therefore examined profitability and efficiency of cucumber production in Iseyin local government area of Oyo state. Primary data on socioeconomic characteristics of farmers, input and output quantity and prices were collected from 73 cucumber farmers and analyzed using descriptive statistics, budgetary technique and stochastic frontier. Majority of the farmers were male (96.7%) with average age of 46.4 years. An average of 17.1 years of farming experience cut across both gender groups. The average hectare was 1.5 with average yield of 5,368 kg/ha. Budgetary analysis revealed that net ...

prominent medium not only among the farmers but also unemployed youths turned famers. This study has
examined constraints militating against fadama vegetable production in Oyo State, Nigeria. It has also examined
involvement of male and female in the production activities. A multi-stage sampling technique was adopted
to sample and administer questionnaires to 73 respondents in the study area. Data were collected and analyzed
using descriptive and inferential statistics. The unavailability of credit sources, high cost of inputs (52.1%) ,
irregular fuel supply (24.7%), frequent pump break down (24.7%), irregularities in water pump operation (16.7%)
and maintenance of the pump (9.6%) were constraints against capital use in the study area. The major
constraints against labour use were the inability to hire labour. The result of the T- test analysis showed that
almost all the activities considered in the study are male dominated. Activities such as land clearing (67%),
Bedding (66%), planting (54%), watering (46%) and digging of well (69%) were male dominated. It is
recommended that there should be provision of credit facilities and initial take off capital for both male and
female for the production of vegetable during the dry season. This will enable them to benefit from the high
profit usually realized in vegetable production during the period.

An integrated vegetable market will permit low spatial and intertemporal variation in
prices, implying that commodity market prices will be functionally related. Vegetables
are important sources of nutrients and income. The study assessed market integration
between urban and rural markets of Amaranthus cruentus L, Corchorus olitorius L, and
okra [Abelmoschus esculentus (L.) Moench] in South-western Nigeria. Data on monthly
prices from 2004 to 2009 was collected from the Oyo State, Nigeria, Agricultural
Development Project. Data were analyzed using augmented Dicker-Fuller and Granger
causality tests and the index of market connection (IMC). Prices of A. cruentus and
C. olitorius were stationary at its level, and the price of okra was stationary by the
ﬁrst difference. Johansen co-integration analysis indicated that rural and urban vegetable
market prices are co-integrated and form part of the same market, indicating a
ﬂow of market price information. The Granger causality test suggested that urban and
rural prices of Corchorus have a causal relationship. Rural okra and C. olitorius exhibited
a bidirectional causal relationship. The IMCs for Amaranthus, Corchorus,andokra
were 0.64, 0.26, and 3.32, respectively, indicating that Amaranthus and Corchorus markets
exhibit high short-run market integration, whereas okra exhibited low short-run
market integration. There is quick transmission of prices between urban and rural
markets for Amaranthus and Corchorus, whereas there is slow transmission of prices
between urban and rural markets for okra because the ﬂow of information regarding
okra prices is not efﬁcient. The policy implication of the study is that market price information
should be made available to farmers through various agricultural programs and
a market infrastructure including transportation and communication facilities should
be developed.

empirical evidences on the Competitiveness and Effect of Government Policies on the commodity. The study
therefore assessed the Competitiveness of Pineapple Production in Osun state, Nigeria. A Multistage sampling
technique was used in selecting 120 respondents within the study area. The study utilized both primary and
secondary data. Data were analyzed using descriptive statistics and Policy Analysis Matrix (PAM). Results
revealed that 58.3% of the producers used sucker technique in pineapple production while 46.2% used crown
technique. PAM results revealed that the crown and sucker production techniques were privately (N550, 438/ha
and N679, 138/ha) and socially profitable (N730, 228/ha and N841, 828/ha) with Sucker production technique
having higher competitiveness. Nominal Protection on Input and Output and the Effective Protection
Coefficients for the two production systems indicated presence of tax and the producers were not protected by
policy. Subsidy Ratio to Producer (SRP) value obtained for crown (-0.16) and sucker (-0.14) techniques and
Producer Subsidy Estimate (PSE) value of -0.18 was obtained for Crown and sucker (-0.15) techniques
indicating pineapple producers’ income were transferred to consumers and taxpayers which further confirmed
that Pineapple production was taxed by policy. Sensitivity analysis indicated that increase in Free On Board
(FOB) price; Farm gate price, Yield and Exchange rate at 20% improved Competitiveness and Comparative
advantage of Pineapple production. The study recommends provision of incentive structures that will protect
pineapple producers.

security and economic development of the country. There is inadequate information on competitiveness,
comparative advantage and effects of government policies on the commodity. The study therefore analyzed
competitiveness and effects of government policies on plantain production systems in Southwestern Nigeria.
Primary data were collected using structured questionnaire from 260 producers randomly selected from
major production areas in the zone. Secondary data on port charges and world prices were also utilized.
Data were analyzed using Policy Analysis Matrix (PAM). Results indicated that plantain production was
privately and socially profitable in all the productions systems. Domestic resource cost ratio of 0.16 – 0.19
and social cost benefit ratio of 0.20-0.23 revealed that southwestern Nigeria had comparative advantage
in the production of the commodity. The policy indicators and incentives structure such as the nominal
protection coefficient on output (0.31-0.42) and input (1.02-1.04), effective protection coefficient
(0.26-0.37), profitability coefficient (0.21- 0.32), subsidy ratio to produces (-0.51 to -0.62) and producers
subsidy estimate (-1.70 to -2.02) showed that the producers were taxed and there exists transfers of resources
from the systems. The study recommends formulation of policies which are consistent with the country’s
goals of agricultural transformation, food security and economic development

VT563/JM94/47 and Ibadan local in Ibadan, Oyo State. A random sampling technique was used to collect
information on traders= characteristics, types of post harvest loss, intensity of damages and marketing margin
accrued from the losses. The data were analyzed with the aid of descriptive statistics, simple margin analysis
and t-test. The results showed that more men were involved in wholesaling of tomato while more women were
involved in retailing of tomato. Most of the respondents have been in the business for more than 10 years. The
major causes of economic losses to tomatoes were physiological, pathological and mechanical damages. In the
UC82B variety, pathological damage constituted the greater percentage (44%) of losses; while the greatest
cause of damage in Roma and VT563/JM94/47 was physiological and was put at 44% and 36% respectively.
Ibadan local suffered the highest kind of damage traced to mechanical factors to the tune of 39%. . There was
a significant difference (p<0.05) in the mean percentage damage of UC82B compared to the three other tomatoes
varieties (P<0.05), while there was no significant (p>0.05) difference between mean percentage damage of
VT563/JM94/47 and Ibadan local varieties. Based on the losses in the marketing margin, there was reduction
of 34% in marketing margin of UC82B, Roma 85%, VT563/JM94/47 94% and Ibadan local 79% at the retail level.
Provision of improved mode of transportation and storage, is thereby recommended to minimize losses in
tomatoes.

The efficiency of resource use of pepper production in Kano State, Nigeria, was studied. Sixty farmers from three local government areas were selected. A questionnaire was used to obtain information on socioeconomic characteristics and other relevant variables. Data were analyzed with descriptive statistics and stochastic frontier production. Seed, hired labor, and fertilizer significantly and positively affected pepper output. Significant determinants of grower technical efficiency were negatively affected by household size and positively affected by farming experience. Problems affecting pepper production were inadequate access to inputs (50%), low price of pepper (33.3%), pests and diseases (15%), and inadequate capital access (1.7%). Use of good quality seed at recommended rates and fertile soil are required to facilitate pepper production at the frontier.
