Abstract

A technology demonstration of ajwain (Trachyspermum ammi L.) was aimed to improve the production after bringing new variety into cultivation in Vijayapur district of northern Karnataka. Studies were carried out to assess yield and economics of a new variety, AA-1 and AA-93 at the farmer’s field under on farm testing trial (OFT) for two years (2019-20 to 2020-21). Among different ajwain varieties AA-1 recorded significantly higher yield (1170 and 1192 kg ha-1) as compared to local variety Kadapa (772 and 812 kg ha-1). Similar trend was observed for growth and yield parameters. The highest gross returns (Rs. 179088 and Rs. 178111 ha-1) and BC ratio (4.32 and 4.44) for 2019-20 and 2020-21 respectively were realized with AA-1 variety as compared with farmer’s variety Kadapa.
