| dc.description.abstract | The study attempts to investigate the constraints facing the oil seed crops production and marketing with special emphasis on sunflower. The specific objectives of the study were to investigate factors limiting sunflower production and marketing, to describe the marketing channels and the roles of institutions involved in marketing of sunflower, to assess the relative net returns of crops enterprises competing with sunflower for resource use in the district. Eleven sampled villages in Iramba district were selected based on differences of climate, transport problems, and accesibility to sunflower markets. From these villages, 110 farmers were selected as a source of primary data. In addition, 20 sunflower traders and 20 oil millers were also selected for primary data in the surveyed area. Secondary data were collected from Singida regional and Iramba district agricultural offices, Tanzania Food Nutrition Centre (TFNC), Institute of Production Innovation (IPI), Marketing Development Bureau (MDB), Agricultural Research Institute - Ilonga, Sokoine National Agricultural library, and Library of University of Dar es Salaam. Descriptive, gross and market margins, regression and probit analyses were used to analyse the data. Survey results revealed that there were a number of constraints to sunflower production and marketing. The most significant constraints identified were poor marketing arrangements and low price of sunflower produce. It was found out that there were mainly six marketing channels of sunflower in the study area. The study showed that competing crops for resource use was not a factor limiting sunflower production and marketing. In this study, the following recommendations were made: (1) Effective extension services should be in place to enable farmers improve crop husbandry practices. (2) Policies to induce the establishment of an econofoically viable credit system for agricultural inputs need to be designed and given to fanners. (3) Improvements in the marketing system in terms of prices and participants in sunflower marketing is needed. (4) A massive investment in roads, storage, processing and other rural infrastructure facilities is required. | |
