Research methodology is the underlying principles and rules of organization of philosophical system or inquiry procedure (Urdong, 1968). A project implemented in the north-western part of Bangladesh, including only six Upazilas under six districts of Rajshahi and Rangpur divisions to assess the impact of AWD technique on rice production, where totally 108 farmers were selected as the participant of the study. Project farmers (54) used irrigation water following AWD technique, while non-project farmers (54) followed the conventional practice (conventional technique). Farmers cultivated six selected rice varieties namely BR26, BRRI dhan28, BRRI dhan29, BRRI dhan45, Minikit and Nerica, following both AWD technique and farmers’ practice (FP) in each Upazilla. The entire process of data collection took two months from January to March, 2013. In order to collect relevant information from the participants, an instrument was carefully designed keeping the objectives of the study in mind. The instrument contained both open and closed questions. Ten farmers similar to the study group were interviewed through pre-testing testing. The final version of the instrument was prepared on the basis of reliability and the suggestions and comments of the panel of experts. The descriptive and diagnostic research design was applied in the present study, because the descriptive research design supports in stating characteristics of a particular situation, or a group or individuals and used for fact finding with appropriate interpretation. Contrastingly, diagnostic and analytical research design helps on testing of hypothesis and specifying and interpreting relationship of variables. The variables of this study were participant’s age, education, family size, farm size, training experience, extension contact, annual family income, organizational participation and impact of AWD technique on rice production, which were determined by comparing yield difference, irrigation requirements, labor requirements and pest infestations between AWD and farmer’s practice. Different variables of the experiment like age, education, farm size, family size, family income, training experience, extension contact and impact of AWD on rice production were measured on the basis of different scale. Factors affecting cultivation of rice was measured on the basis of 22 selected factors under biophysical, technical, socio-economic and institutional category. A 4-point rating scale was used for the measurement, where a participant was asked to indicate the extent of problems of each factor. The possible responses in the scale representing extent of problems were “no problem”, “low”, “medium” and “high” while the assigned scores for the responses were 0, 1, 2 and 3, respectively. The SPSS software program version 16.0 was used to perform for data analysis. Descriptive statistical measures like range, mean, number and per cent age distribution, standard deviation were used to describe and interpret the data. Paired sample t-test is a statistical technique that is used to compare two population means in the case of two samples that are correlated. For exploring the impacts of AWD technique paired t-test was used in this study. Throughout the study 5 per cent (0.05) level of probability with an accompanying 95 per cent confidence level was used as a basis for rejecting or accepting the null hypothesis. Here the following formula was used to measure the value of parameter with 5 per cent level of significance with n-1 d.f.
