Rationality and Validity of itKs on Plant Protection and Post-harvest technology of tribal farmers in telangana

Abstract

This study was conducted in Adilabad, Khammam and Warangal districts of Telangana. Ex post-facto research design was followed in this study, since different variables chosen for the study had already occurred. An effort was made to document the indigenous technology of tribal farmers. A questionnaire containing lists of ITKs was prepared and exposed to the scientists for judging the rationality and validity of ITKs on a three point scale wherein, 3 is rational, 2 undecided and 1 is irrational. The mean score was calculated by summing the scores overall and divided by the number of judges for a given item and if it was more than two then the item was considered as rational and less than two was considered as irrational. For validity, the scientists were asked to find out the valid ITKs among rational ITKs which were validated, tested and verified on the basis of research. Out of 41 ITKs on plant protection and post-harvest technology, only 32 ITKs (78.04%) were found rational and the remaining 9 ITKs (21.96%) were found irrational, while, 30 ITKs were found valid.
