Front Line Demonstration on rice variety CAU R-1 was conducted in the Leparada District of Arunachal Pradesh in the year of 2019 to 2022 by Krishi Vigyan Kendra, West Siang during the Kharif season. The demonstration was conducted in 40 farmers’ field covering 18 hectares of area. The study was conducted for Grain yield, Yield gap, Technological gap, Extension gap, Economic gains and Technology Index. The demonstration showed that the average grain yield was lowest in 2019 (43.00 q/ha) and highest in 2022 (46.50 q/ha). The average grain yield of farmers’ practice was lowest with 30.00 q/ha in 2019 and highest in 2022 with 34.86 ql/ha. Percentage of increased yield of the demonstration over the farmers’ practice ranges from 33.30% to 43.30%. In case of Technological gap/yield gap, extension gap and technological index the value decreased from 2019 to 2022 with the value of 27.00 to 23.50 (Technological gap/yield gap), 13.00 to 11.64 (extension gap) and 38.60% to 33.60 % (technological index). In term of economic study, the benefit cost ratio of the demonstration ranges from 1.72:1 (2019) to 1.76:1 (2022) whereas the farmers’ practice benefit cost ratio ranges from 1.16:1 (2019) to 1.28:1 (2022). The yield potential of rice can be increased to a great extent by using high yielding varieties with improved technologies through front line demonstration. Accordingly, the production and the productivity of rice will be increased resulting in sustainable and profitable farming at the same time reducing the technology gaps.
