Abstract: Rapeseed-mustard is a major oilseed crop in the Jammu region of Jammu and Kashmir, contributing significantly to the rural economy and nutritional security. Despite the availability of high-yielding varieties and recommended rapeseed mustard cultivation practices of SKUAST-Jammu, the adoption rate among farmers remains low. This gap in adoption is largely attributed to insufficient knowledge and awareness about improved technologies, which negatively impacts productivity and farm income. Keeping in view the above problem, the present study was undertaken with the objective of developing a standardized knowledge test to assess farmers' knowledge regarding improved rapeseed-mustard production practices. Critical aspects of rapeseed-mustard production were compiled and reviewed with scientists to ensure relevance and accuracy. Indices for item difficulty and discrimination were obtained through item analysis. The respondents were given one mark for each correct and zero for incorrect answer. The reliability of the test was assessed using the split-half method, resulting in a coefficient of 0.79. To estimate the reliability of the full-length test, the Spearman-Brown prophecy formula was applied, producing a coefficient of 0.88, indicating high reliability. Furthermore, the test demonstrated an acceptable degree of content validity as ensured through expert consultation and review. Based on the results, a total of 23 items were selected for the final test.
