Paddy is a major cereal crop of India and Karnataka. In Chamarajanagara district, majority of it is grown under Kabini command area covering Yalandur, Kollegala and Chamarajanagara taluks. Paddy farmers of the area are cultivating IR 64 variety which is very old, poor yielding under salt affected soil conditions and susceptible to major diseases. In order to enhance the yield at farmers level, a new variety GGV–05–01 (Gangavathi Sona) released by UAS Raichur, a salt tolerant variety, also tolerant to sheath blight and blast diseases was tested in comparison with IR 30864 and Vikas (UAS Bangalore varieties) suitable for salt affected soil and farmers variety IR-64 for three years in the farmers’ field. An average maximum yield of 5.41 t ha-1 was obtained with GGV-05-01 followed by IR 30864 (5.12 t ha-1), Vikas (4.75 t ha-1) and IR 64 (4.56 t ha-1). Similar trend was observed with growth, yield parameters and economics. With this background, the variety GGV-05-01 was upscaled to frontline demonstration. The variety was given to 27 farmers of Irasawadi, Y.K. Mole, Uppinamole and Ambale villages of Chamarajanagara and Yalandur taluk during 2016-17 and 2017-18. IR 64 was considered as a check variety. GGV-05-01 recorded an increased yield of 34.6% over check. Similar trend was observed with harvest index and BC ratio. During 2018-19, the horizontal expansion was 28.4 ha accounting to 1775 kg seeds that were supplied by farmers themselves and this variety was endorsed by UAS Bangalore for cultivation in maidan areas of Cauvery command which has enabled good quality seed supply to the paddy growers.
