Due to the non-availability of a standardized scale to measure the Knowledge of farmers on integrated weed management (IWM) practices in major crops it was thought necessary to construct a test for the purpose and an attempt was made to develop a test for measuring knowledge of farmers on IWM practices in major crops. Pertinent items were collected covering all aspects of IWM practices. After getting jury's opinion on the items index of item difficulty, index of item discrimination and index of item validity were worked out. To administer the knowledge test a respondent was given one mark for each correct answer and zero for each wrong answer. One hundred twenty one statements were finally selected from 140 statements.
