It provided employment, food, raw materials for industry and foreign exchange. However, within 20 years of Independence the country became unable to cope with the overall needs of its food and raw materials. Increased foreign exchange earnings from the export of crude oil were implicated as leading to the neglect and subsequent decline in the performance of the Nigerian agricultural sector. The Structural Adjustment Programme SAP was adopted to restructure and diversify the productive base of the economy in such a way as to reduce dependency on the oil sector and imports. One of the key policy strategies designed to achieve the Nigeria's SAP goals was the adoption of a market-determined exchange rate. This paper set out to assess the impact of exchange rate deregulation and SAP on cotton production and utilization in Nigeria. Time series data on aggregate cotton production, Naira’s average cross exchange rates with the US dollar and average capacity utilization rate of textile manufacturers in Nigeria for the period 1973-2007 were collected and analysed using Multiple-regression and the student’s t test technique. Findings includes: exchange rate deregulation per se has no significant effect on cotton production in Nigeria; more cotton was produced in Nigeria during the post-SAP period; the average capacity utilization of domestic textile industry in Nigeria during the pre-SAP period was higher than during the post-SAP period. Based on the findings of the study some noteworthy lessons were highlighted.","PeriodicalId":150128,"journal":{"name":"Trends in Agricultural Economics","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121731318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The econometric models include single equation model using Vector Error Correction Method (VECM) and multivariate autoregressive-moving average (MARMA) model. The models were developed to determine the inter-relationships between NR production, consumption and prices, to forecast the price of NR (SMR20) and to determine which model is more efficient in their price forecasting accuracy. The models based on data from period January 1990-December 2008. Comparative forecasting models accuracy between single equation model, MARMA model and univariate model of ARIMA, were made in terms of their estimation accuracy based on RMSE, MAE, RMPE and (U-Theil) criteria. The results revealed that the values of the RMSE, MAE, RMPE and U of MARMA model were comparatively smaller than the values generated by single equation model and ARIMA model. These statistics suggested that MARMA model is more accurate and efficient measured in terms of its statistical criteria than single equation model and ARIMA model in forecasting the NR price of SMR20 in the next 6 months or so.","PeriodicalId":150128,"journal":{"name":"Trends in Agricultural Economics","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126035564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its growth varied widely year to year causing fluctuations in production. This study was undertaken to explore the farm insight practices in an economic viewpoint by framing a total of 149 farmers from Mymensingh district in Bangladesh. The study analyzed the farm profitability and other farming practices based on a per hectare basis for the three feed categories and determine the feed contribution to production. Among variables, feed alone experienced 73% of the gross production costs, implies a greater influence of feed on production. Though, the gross cost was higher, hence, the cost of producing per kg fish was the lowest for the floating feed. The farm income also varied with the variation of input costs among the feed brands and the performance of floating feed was found to be outstanding. Furthermore, floating feed yielded the best performances in terms of feed conversion ratio or daily mean weight gain of fish. Although, the initial investment is higher with the floating, feed farmers can earn much additional returns from the extra investment compared to other feed technologies. Generally, with an average revenue of fish was US$ 1.59 kg-1 and cost of US$ 1.38 kg-1, Thai koi production is considered to be a profitable agri-business. Finally, the outlook for the Thai koi farming could be very optimistic in filling the upcoming demand of fish, thus greatly improved human nutrition and food security by removing the problems and constraints are identified.","PeriodicalId":150128,"journal":{"name":"Trends in Agricultural Economics","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114222281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is based on the primary data collected from 50 traders (10 local traders, 12 wholesalers, 10 retailers, 11 processors and 7 exporters) in the markets of Mashhad, Torbat Heydarieh and Ghaen were selected randomly. The secondary data were collected from published sources in Iran such as, Ministry of Jihad-Agricultural, Trade Promotion Organisation of Iran, Customs, ITC, European Commission, etc. Apart from using the usual techniques/concepts for analysing the marketing costs, marketing channels, marketing margin and price spread, Shepherd’s Index was used for computing marketing efficiency. The study reveals that the maximum marketing margins were usurped by the middlemen followed by wholesalers in Mashhad for bulk export to Spain, UAE and Italy traders. The packaging and processing companies, which usually performed the task of grading, incurred the maximum marketing costs. The gross price spread was highest (96.25%) in the direct marketing channel namely: Producer→domestic consumer and least (17.76%) in the channel: Producer→middlemen →foreign traders→foreign consumer. Altogether, 11 channels were identified in the marketing of Iranian saffron and the average share of producer in the consumer’s price in the all the 11 channels was 51.23%. The study revealed that there is considerable scope to increase the producer’s share in the consumer’s price if the number of intermediaries is reduced and the government intervenes pro-actively in order to organize and streamline the marketing cooperatives unions so that the farmers use these unions as a profitable channel to sell their product. There is no effective control on intermediaries in the saffron market, at percent. The problem of irregular supply can be solved by forward contracts to be signed between producers and marketing bodies. The prices of saffron witness frequent fluctuations and even day to day fluctuations-causing concern to the farmers.","PeriodicalId":150128,"journal":{"name":"Trends in Agricultural Economics","volume":"316 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124479101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Augmented Dick Fuller was used for unit root test while both maximum eigen value and trace statistics used for cointegeration test. Vector error correction (VECM) approach was used to estimate long run and short run relationships between maize supply and its estimators. The result of the study indicated that one of the series are non stationary at level but not for the first difference while, some of the series were stationary and the Johanson's method indicated the cointegration of the series. Price factors were more important in the long run than in the short run and maize supply was price inelastic in the long run and technology in elastic in the low lands of the country could be due to predominance of small and marginal land holdings, weak R&D and extension. Non-price factors were comparatively more important for higher supply growth of maize so that policy interventions should focus on improving rural infrastructure specially in the lowlands. More investment on R&D would bring about shift on the maize supply by assuring technological breakthrough on maize yield that many countries have achieved and made the sub-sector attractive.","PeriodicalId":150128,"journal":{"name":"Trends in Agricultural Economics","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131486751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
