Background: Adoption of improved rice varieties is an important strategy for enhancing rice productivity and profitability. Participatory approaches such as on-farm trials and frontline demonstrations help assess the suitability and acceptance of new cultivars under local farming conditions.

Aims: The study aims to find out the performance of improved variety of rice JR 81 and to popularize them among the farming community present study was carried out in the Katni district of Kymore Plateu and Satpura Hills.

Study Design: An on-farm trial and front line demonstration was carried out to examine rice production, yield characteristics and growth features and economics in different location of Katni district.

Place and Duration of Study: Krishi Vigyan Kendra, Katni conducted the present study in six consecutive years 2020-2025 in the form of On Farm Trials and Front Line Demonstrations.

Methodology: This study was carried out at 45 farmers field and 0.4 ha each of Katni district and data on yield and its attributing traits, economics were collected of recommended practices as well as farmer practices. The data were used for estimation of BC ratio, extension gap (q ha^-1), technology gap (q ha^-1) and technology index (%).

Results: In comparison to farmers' practices, benefit-cost ratios were determined to be 2.91.  The demonstration's average technology gap was 6.98 q ha-1 and average extension gap is 10.58 q ha^-1. The mean value of the technology index is 11.63%. This demonstrates the effectiveness of the proven technology-improved variety JR 81 combined with a set of scientific package of practices.

Conclusion: This variety will increase the adoption of proven technology to boost rice yield. This variety was determined to be appropriate since it was well-suited to the current farming conditions and was well-liked by the farmers in terms of grain and yield.
