Yield gap analysis through demonstration in wheat crop under tribal area of Jabalpur, India

Demonstrations (Improved Practice-IP) on wheat variety GW-273 were conducted on farmers ’fields in Villages Bichhua and Sanjari of Kundam Block of Jabalpur district during rabi season of the year 2014–15. Prevailing farmers ’practices were treated as control for comparison with recommended practices. About 29.98 per cent higher grain yield was recorded under demonstrations over the farmers ’practices (Farmer Practice-FP). The average extension gap, technology gap and technology index were observed to be 7.34 q ha⁻¹, 11.41 q ha⁻¹ and 0.25, respectively. The study found, the yield of wheat in IP under irrigated conditions ranges from 24.20 to 42.20 q/ha whereas in FP it ranges between 16.72 to 38.93 q ha⁻¹. The per cent increase in yield with IP over FP was recorded in the range of 0.05 to 76.68. The extension gap and technological index were ranging between 0.02–17.62 q/ha⁻¹ and 0.06–0.46, respectively.
