Abstract/ Executive Summary:

The main purpose of the study was to determine the extent of adoption of selected technologies in prawn culture by the farmers in a selected area of Khulna district. The study also explored the relationship between ten selected characteristics of the farmers and their adoption of selected technologies in prawn culture. An attempt was also made to identify the problems faced by the farmers in the adoption of selected technologies in prawn culture. Data were obtained from 102 randomly selected farmers of two unions under Phultala upazila of Khulna district through personal interviews using an interview schedule. Data were collected from the sampled respondents during 01 August to 15 September, 2005. Among six technologies in prawn culture; extent of adoption was highest for application of supplementary diet, liming and maintaining healthy environment. In case of overall adoption. majority (66.7%) of the farmers had medium adoption while 17.6 % having high adoption and 15.7% had low adoption of selected technologies in prawn culture. Among the selected characteristics of the farmers'. .age, prawn culture experience, annual income, knowledge about prawn culture and cosmopoliteness showedpositive significant relationship with their adoption of selected technologies in prawn culture while, education. farm. size, training experience, extension media contact and organizational participation of the farmers did not show any relationship. Farmers indicated 10 problems in adoption of selected technologies in prawn culture. Among the problems, high price of prawn feed, non-availability of credit in time, non-availability of post larvae in time etc. were the major barriers towards prawn culture.

Keywords: Adoption. Prawn culture, Technology

Location: Two unions namely, Jamira and Damodar under Fultala Upazila of Khulna district.

Start Date: 01-08-2005

End Date: 15-09-2005

Program Area: Socio-economic and Policy

Commodity: Prawn, Adoption of technology

Objectives:

Research has shown that there exist some barriers in adopting technologies or an innovation. There are many factors (i.e., personal, social and psychological) that exerts greater influence on their adoption behaviors and therefore, in order to adopt technologies by the farmers properly in prawn culture, it is of paramount importance to have taken a study on the adoption of technologies in prawn culture by the farmers.

Methodology:

This study was conducted in two unions namely, Jamira and Damodar under Fultala upazila of Khulna district. With the help of Upazila Fisheries Officer, his field staff and local leaders, an updated list of prawn farmers was collected. In Jamira union, there were 610 prawn farmers and in Damodar union, the number stood 410. Thus, 1020 prawn farmers of two selected unions constituted the population of the study. From the population, the sample respondents were then selected at the rate of 10 percent (102) following simple random sampling method (Kerlinger, 1973). An interview schedule was prepared for collection of data. Data were collected from the sampled respondents during 01 August to 15 September, 2005. The dependent variable of this study was adoption of selected technologies. Among the technologies, main focus was given on removing of predatory and unwanted fish, liming, application of balanced fertilizers, establishing shelter, application of supplementary diet and maintaining healthy environment. The dependent variable was computed by using following formula:

Adoption Index (AI) = Eel p / Ps x 100

Where, E=Summation of e/p e= Extent (i.e. actual adoption) of adoption of selected technologies in prawn culture in a particular land in particular year p= Potentiality (i.e. Possible adoption) of selected technologies in prawn culture in a particular land in a particular year. Ps = Period under study. In this study it was of four years i.e. 2001, 2002, 2003 and 2004. The adoption index was expressed in percentage.

The selected characteristics of the farmers such as age, education, prawn culture experience, farm size, annual income, knowledge about prawn culture, training experience, extension media contact, cosmopoliteness and organizational participation were treated as independent variables of the study. Age of the respondents was measured in terms of actual years from their birth to the time of interview. A score of one (1) was assigned for each year of one's age. Education of a respondent was measured on the year of schooling in formal educational institution. A score of 0.5 was given to that respondent who could sign his name only. Prawn culture experience was determined by assigning 1 for each year of working experience of a respondent either in his own prawn gher or with that of his parents. The farm size of a respondent was measured in hectares. Annual income of a respondent was measured in taka on the basis of his total yearly earning from different sources. Knowledge about prawn culture was measured by computing knowledge about prawn culture score. Each respondent was asked to answer 15 questions and score was assigned as 2 for correct answer. 1 for partially correct answer and 0 for incorrect answer for each question. Training experience was operationalized by the total number of days a respondent attended in various training courses offered by different life time. Extension media contact was computed on the basis of the extent of contact of a respondent with 13 selected information sources. cosmopoliteness and organizational participation were measured by as usual methods which are exiting in social science. Descriptive statistics such as number, percentage, mean and standard deviation were used in describing variable of the study. Correlation analysis was employed for exploring relationship between dependent and independent variables.

Achievement/Findings:

Among the selected characteristics of the farmers'. age, prawn culture experience, annual income, knowledge about prawn culture and cosmopoliteness showed positive significant relationship with their adoption of selected technologies in prawn culture while, education. farm. size, training experience, extension media contact and organizational participation of the farmers did not show any relationship. Farmers indicated 10 problems in adoption of selected technologies in prawn culture. Among the problems, high price of prawn feed, non- availability of credit in time, non-availability of post larvae in time etc. were the major barriers towards prawn culture.
