French bean (Phaseolus vulgaris L.) is the most important leguminous vegetable crop known for its short duration and nutritive values. Its production enhances soil fertility and  best suitable for intercropping. The efforts have been made to conduct front line demonstrations and dissemination of pertinent knowledge to French bean growers about improved technologies (Arka Sharath). The present study ascertains impact of frontline demonstration conducted by Krishi Vigyana Kendra (KVK), Shivamogga of Karnataka on french bean variety Arka Sharath. It is a photoinsensitive, stringless high yielding variety suitable for irrigated conditions. Total of 15 demonstrations were conducted in 15 farmers field in an area of 3.5 ha during 2015-16 to 2016-17. The results indicated that marked difference between Arka Sharath and local variety being adopted by farming community. Arka Sharath comes to harvest earlier than local variety. The duration to first harvest in case of Arka Sharath was 50-55 days after sowing while it was 60 days in case of local variety. In terms of number of harvest, it is more in case of Arka sharath (7) compared to control (5). The time interval between successive harvests is 8 days in case of Arka sharath and 10 days in case of local variety. In terms of pod weight, farmers expressed that pod weight is 36 percent higher in case of Arka sharath compared to local variety. The profitability in terms of B:C ratio was 3.97 in case of Arka sharath as compared to 3.33 in case of local. The significant achievement of frontline demonstration is the magnitude of technology dissemination which is to the tune of 160 acre in 2015-16 and 195 acre in 2016-17. It could be further observed that about 130 sample farmers have adopted this technology during 2015-16 and 155 during 2016-17.
