The present study was conducted at the farmers' fields of Dausa district of Rajasthan (India) to investigate the impact of cluster front line demonstrations on chickpea during rabi 2016-17 to rabi 2021-22. A total of 575 demonstrations of chickpea in 260 ha area having similar number of traditional practices or local check were carried out in sandy loam soil under irrigated conditions of Dausa district. Yield of front line demonstrations trials and potential yield of respective variety and year were compared to estimate the yield gap which were further categorized into technology gap and extension gap. The technology gap was recorded highest (5.70 q/ha) in case of GNG-1581 during 2017-18 and lowest technology gap (3.87 q/ha) was recorded in case of CSJ-515 during 2021-22. The extension gap was the highest during rabi 2020-21 (4.95 q/ha) and lowest during rabi 2021-22 (2.30 q/ha). The average technology gap was 4.83 q/ha and the average extension gap was 3.56 q/ha. The technology index was maximum during rabi 2017-18 (21.92%) while minimum during rabi 2021-22 (16.13%). Average technology index was recorded 18.63%. The highest yield (22.40 q/ha) of chickpea demonstrations was recorded during rabi 2020-21 with variety GNG-2144 while lowest yield (19.73 q/ha) was recorded during rabi 2017-18 with variety CSJ-515. Average yield of demonstrations was 21.05 q/ha whereas average yield of local check was 17.50 q/ha, representing 20.40% yield increase in demonstrations over local check. The average gross return was Rs 92623 which was 20.99 per cent higher over control. The average net return was Rs 53065 which was 58.74 per cent higher over local check. The average B:C ratio of the demonstrations was 2.31 while it was 1.82 in local check
