Abstract: Front Line Demonstration is one of the most powerful tools for transfer of technology. The present study was undertaken to find out the yield gap through FLDs on wheat crop. Krishi Vigyan Kendra, JAU, Amreli(Gujarat) conducted 100 demonstration on wheat since 2006-07 to 2009-10 in different seven adopted villages. Prevailing farmers’ practices were treated as control for comparison with recommended practices. The average four year data observed that an average yield of demonstrated plot was obtained 43.26 q/ha over control (36.59q/ha) with an additional yield of 6.67 q/ha and the increase average wheat productivity by 18.22 per cent. The average technology gap and index were found to be 6.74 and 13.48 per cent.
