Rice is estimated to contribute about 2.5 percent of Gross Domestic Product (GDP) of India. Rice cultivation in Tamil Nadu is done in kuruvai, and samba seasons, Kancheepuram and Tiruvarur districts had a maximum area under CO 51 cultivation; these two districts were purposively selected for the study with a sample size of 300 respondents. The annual income can be sustained and increased through the adoption of high-yielding rice variety CO 51. It is possible through social participation that includes extension agency contact, which leads to undertaking training, and the educational status facilitates the same. The age of a farmer and the educational status will impact social contact, which is essential for moving out and establishing contact with extension agencies. The extension agency contact had a significant relationship with adoption in both the Kancheepuram and Tiruvarur districts. These factors, combined with credit orientation and farm size, plays a significant role in the adoption. Thus, with a limited scope on other fronts, the farmer has to necessarily raise production levels and adopt the latest variety, which has more yields. This study recommends the policies to build initiatives on widespread of an improved package of practices, which results in the adoption of rice variety, CO 51 cultivation.
