Abstract: Front line demonstration is an appropriate tool to demonstrate recommended technologies among the farmers. Krishi Vigyan Kendra, Bastar (Chhattisgarh) conducted 286 demonstration on chickpea from 2015-16 to 2018-19 in adopted villages. The critical inputs were identified in existing production technologies through bench mark survey. The recommended packages of practice were adopted by the farmers in all the villages. The training programme on different aspects of crop production technologies were orga­nized among beneficiaries and other participating farmers. Seed yield of chickpea in the demonstration plot varied from 15.70 q/ha during 2018-19 to 12.50 q/ha during 2017-18. Average seed yield under improved practice (IP) (14.01 q/ha) was 51.7% higher over farmer’s practice (FP). The per cent increase in yield with IP over FP was recorded in the range of 36.8 to 60.2. The technology gap and extension gap were in the range of 4.30-7.50 q/ha and 3.36-5.90 q/ha respectively. Technology index value varied from 21.5% to 37.5% during the study period. The benefit cost (B: C) ratio was 2.81 to 2.95 under demonstration, while it was 2.15 to 2.57 under control plots. The average B: C ratio under IP (2.86) was 24.9% higher over FP.
