Locale of the study area
Gazariaupazilla of Munshigonj district consists of eight unions namely, Gazaria, Imampur, Hoshendi, Vaberchar, Baoshia, Baluakandi, Guagachhia and Tengercharunion.Out of these upazillaGazaria and Imampur unions were selected purposively as the locale of the study area. Then Six villages were randomly selected by using simple random sampling method. The selected villages were Nagerchar, Prodhanerchar, Bairabdi, Uttar Fuldi, Karimkha and Rasulpur.
Population and Sampling Design
All potato growers of Gazaria and Imampur union under Gazariaupazila constituted the population of the study.An Update list of 585 potato growers from the selected villages were prepared with the help of Sub-Assistant Agriculture officer. Twenty (20%) percent of the population were randomly selected as the sample of the study by using random number table. Thus, 116 farmers constituted the sample of the study. A reserve list of ten farmers was also prepared by the same method so that the respondents of this list could be used for interview if the respondents included in the original sample were not available at the time of data collection.
Validity and reliability
An instrument is considered as valid when it measures what it claims to measure. It is usually deemed to be valid when the objectives of the study are reflected in the instrument. Validity as “Descriptive term used for a measure that accurately reflects the concept that is included to measure”(Bobbie, 1986). A test or scale is reliable if it yields consistent results when repeated measurements are taken on the same subjects under the similar condition.
Pilot Testing and Final Version
Borg and Gall (1979) indicated that before going to data collection the instruments to be tested in the study area a pilot study programme. Accordingly interview schedule initially developed was tested within a similar group of farmers excluding respondent farmers. Fifteen potato growers were interviewed by using the instrument. The pretest helped to examine the suitability of different questions and statements of the instrument in general. Necessary corrections, additions, alterations and rearrangements were made in the schedule on the basis of the experience of the pretest. Thus, the final version of the instrument was developed for collation of data from intended respondents.
Data Collection
Data were collected personally by the researcher himself by interviewing the potato growers with the help of interview schedule. The researcher made all possible efforts to explain the purpose of the study to the farmers. Rapport was established with the farmers prior to interview and the objectives were clearly explained by using local language as far as possible. As a result, the respondents did not hesitate to furnish proper responses to the questions and statements which were collected during the period from 10 December 2007 to 29 January 2008.The researcher sought the help from the local leaders and the Sub-Assistant Agricultural officer for this purpose. Excellent co-operation was obtained from the respondents, the concerned local leaders and the Sub- Assistant Agricultural officers.
