Frontline demonstration (FLD) is one of the most powerful tools for transfer of technology. Keeping in view the effective extension approach of FLDs for dissemination of paddy technology, an impact assessment of FLDs conducted by KVK, located in Jammu and Kathua Districts of Jammu and Kashmir was assessed. The impact was based on the comparison of beneficiary and non-beneficiary respondents with reference to their socio-personal profile, knowledge level, extent of adoption of improved paddy production and benefit-cost ratio. Based on random number sampling total sample of 80 respondents (40 beneficiaries and 40 non-beneficiaries) were interviewed using a structured interview schedule. The results showed that one third of the respondents (37.50%) were noticed to fall under age interval 36-50 years and majority of the respondents have marginal land holding (40.00%) and main source of irrigation was canal. KVK act as the main source of information to the beneficiaries while non-beneficiaries were mainly dependent upon the input dealers for information. In paddy majority (72.50%) of the respondents possessed high level of knowledge in case of beneficiaries while only 57.50 per cent of respondents possessed high level knowledge in case of non-beneficiaries. A significant difference was found between beneficiaries and non-beneficiaries related to the adoption of recommended seed rate, seed treatment, use of DAP in nursery, fertilizer usage in main field & diseases management of rice and the results of linear regression showed that none of the selected variables had significant contribution with the adoption of various practices in paddy. By calculating the benefit-cost ratio of both beneficiaries and non-beneficiaries, it was found that the beneficiaries achieved more returns on their investments as compared to non-beneficiaries in case of rice.
