Tungabhadra project (TBP) irrigates almost 5.20 lakh ha area, out of which 3.50 lakh ha area of three districts of Karnataka and 2 lakh ha area of Andra Pradesh. In Karnataka it covers part of Koppal district mainly Gangavathi and Koppal talukas, where in Rice is the predominant sole double crop and hence rightly called as “Rice Bowl of Karnataka”. Ever since the rice cultivation has begun, BPT-5204 is the predominant Kharif variety covering almost 90-95 per cent of rice growing area and of recent became prone to multiple pest and disease resulting in increased cost of cultivation. TBP command area is characterized by intensive cultivation (Both fertilizer and pesticides). In such a situation, an alternate high yielding variety to BPT-5204 and assured market was the need of the hour. As a coincidence central government sponsored seed village programme was allotted to KVK, Koppal (situated at Gangavathi) for introduction of new variety during 2011-12. The seeds of newly released variety Gangavathisona (GGV-05-01) by Agricultural Research Station, Gangavathi were distributed to farmers at 50 per cent subsidized rate. After harvest the yields were higher than BPT-5204, economics indicated that higher net returns of Rs. 3,124/ha can be obtained simply by changing the variety. Further as the variety was new to the ecosystem, the incidence of most of the pests and diseases were lower compared to BPT-5204. Gangavathisona (GGV-05-01) was a duel season variety and was suitable to be grown in both Kharif and Summer seasons.
