Yield gap analysis of rapeseed-mustard through front line demonstrations in agro climatic zone IVa of Rajasthan

Abstract

The present study was carried out at Krishi Vigyan Kendra, Rajsamand to know the yield gaps between
improved package and practices (IP) under Front Line Demonstration (FLD) and farmer’s practice (FP) of
rapeseed-mustard crop. The study found, the yield of rapeseed-mustard in IP under irrigated conditions
ranges from 15.89 to 18.64q/ha whereas in FP it ranges between 12.53 to 14.02q/ha. The per cent increase
in yield with IP over FP was recorded in the range of 26.82 to 33.14. The extension gap and technological
index were ranging between 3.36-4.64q/ha and 22.33-33.79 per cent, respectively. The trend of technology
gap reflected the farmer’s cooperation in carrying out demonstrations with encouraging results in subsequent
years. The cost benefit ratio was 3.19 to 3.52 under demonstration, while it was 2.36 to 2.69 under control
plots. By conducting front line demonstration of proven technologies, yield potential of rapeseed –mustard
crop could be enhanced to a great extent with increase in the income level of the farming community.
