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

Abstract

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.
