Evaluation of Frontline Demonstration of Greengram (Vigna radiata L.) in Kalaburagi Region of Northern Karnataka

Greengram (mungbean) isoneof the important pulse crop in India, plays a major role in augmenting the income of small and marginal farmers of Northern Karnataka. The low production of traditional varieties of greengram was a cause of concern for the farmers at large. To overcome this problem of low yield, Krishi Vigyan Kendra of Kalaburagi has conductedfrontline demonstration fieldof adopted villages. Cultivation of high yielding variety BGS-9 of greengram has given yield increase of 30.00, 13.03, 13.15 and 15.40 percent during 2010–11, 2011–12, 2012–13 and 2013–14, respectively over local check. The technology gap ranges from 12.5 to 18.5 during the experimental period. The highest extension gap of 18.5 was recorded in during 2010–11. This high extension gap in all these varieties requires urgent attention from planners, scientists, extension personnel and development departments. The technology index varies from 58.36 to 74. The changes will accelerate the adoption of newer technologies to increase the productivity of greengram in this area. There is a need to adopt multi pronged strategy which involves enhancing greengram production throughhorizontal and vertical expansion and productivity improvements throughbetter adoption of improved technology.
