The present investigation on red gram was conducted in different villages of Nalgonda and Yadadri Bhuvanagiri district of Telangana state during the kharif season (June-January) of 2018-19, 2019-20, and 2020-21 respectively. Total of 30 demonstrations was organized in farmer’s fields in the districts during the study period. The main objective of frontline demonstration is to increase the productivity, economics of red gram and to decrease the yield gap. Results revealed that the average red gram yield registered under the demonstration plot was 1517 kg ha-1   in comparison to 1397 kg ha-1 under farmer’s practice field with a percentage increase of 8.59. During the study period the average gross returns (86833 Rs ha-1), net returns (56145 Rs ha-1) and B: C ratio (2.83:1.0) was more in demonstration plot when compared to farmers practice (79945 Rs ha-1 gross returns, 48953 Rs ha-1 net returns and 2.59:1.0 B: C ratio respectively). Further, there was average increase of additional returns of Rs 12904 ha-1, Rs 1635 ha-1 and Rs 7036 ha-1 recorded in demonstrated technology during 2018-19, 2019-20 and 2020-21 respectively. Regarding the yield gap analysis, average extension gap of 120 kg ha-1, technology gap of 483 kg ha-1 and technology index of 24.15% was recorded. By adopting innovative approaches like large scale demonstrations, real demonstrations, the extension gap and technology gap could be reduced further for different farming systems to attain self-sufficiency in pulses thereby increase in farmers’ income.
