2.1 Area selection: The Shutia Khali ward of Boira Union of the Mymensingh Sadar Upazilla, Bangladesh was selected as the study area as this ward is situated at the flood plain of the old Brahmaputra River i.e. AEZ 9. The soil falls under the general soil type non-calcareous dark grey floodplain and taxonomically it belongs to order inceptions. Hence, lot of problems arises due to the soil erosion, due to flood, surface run-off, due to rain water etc. Its geographical coordinates are 240 41' 0" North and 900 26' 0" East.
2.2 Method of data collection and period of study For collecting data, personal interview from the individual respondent was carried out at their home. An introductory visit was made to the study area to become familiar with the respondents and their environment. During visit the objectives of the study were explained clearly to most of the respondents. This assists the researcher to have a friendly orientation with the respondents. The researcher also established desired rapport with respondents. Questions were asked systematically and explanations were made whenever it was felt necessary. The information supplied by the respondents was recorded directly on the interview schedule. The information was checked carefully before leaving the study area in order to minimize errors. Data were collected in local unit. These were subsequently converted into appropriate standard units. The respondents were interviewed at their own house in leisure time so that they could give accurate information in a sound mind. The data were collected from 140 respondents from February 3 to March 31, 2015. Excellent co-operation was received from all respondents during collection of data. The questionnaire was carefully designed keeping the objectives of the study in view.
2.3 Sampling technique adopted The study was conducted in rural areas of Mymensingh Sadar Upazila. The people of the villages are constituted the population. The population constituted 680 households. Among the population, 140 respondents were selected by simple random sampling technique. A structured interview schedule with open-ended and closed-ended questions was developed. Data were collected through personal interview during February 3 to March 31, 2015.
2.4 Measurement of variables A variable is any characteristics which can assume varying or different values in successive individual cases. There are two types of variables such as independent and dependent variables. A dependent variable is that factor which appears, disappears or varies as the researcher introduces, removes or varies the dependent variables. The independent variables were age, sex, educational status, farm size, annual income, household size and extension service. The land management techniques (crop rotation, mixed cropping, residue management, planting trees/agroforestry, intercropping) were dependent variable in this research.
2.5 Data analysis The information obtained from all the respondents were coded, compiled and tabulated in MS Excel sheet after completion of the survey. Then (SPSS v 20) data software was used for analyzing the coded data from MS Excel sheet. Basic statistics such as frequency (number of the respondents), percentage distribution, range, mean and standard deviation were used in describing the variables of the study. Pearson's Product Moment Correlation co-efficient (r) was used to compute the linear relationship among the variables with one percent (0.01) level of probability and five percent (0.05) level of probability was used to accept or reject any null hypothesis.
