Yield Gap Analysis of Toria (Brassica campestris) through Front Line Demonstrations in Kandhamal District of Odisha

Abstract

The present study was carried out at Krishi Vigyan Kendra, Kandhamal to know the yield gaps between improved package
and practices (IP) under Front Line Demonstration (FLD) and farmer's practice (FP) of toria crop. Yield attributes of both
demonstration and farmers' practice were recorded and their yield gap, technology gap, extension gap and technology
index were analyzed. The average five years data revealed that an average yield of demonstrated plot was obtained 10.01
q/ha over local check (6.55 q/ha.) and there is an increase in average productivity by 52.97 per cent. On an average
technology gap was recorded to be 1.99 q/ha. While average extension gap was observed to be 3.46 q/ha. Average
technology index was recorded as 16.63 per cent. The average cost benefit ratio was 2.55 under demonstration, while it
was 1.75 under control plots. The trend of technology gap reflected the farmer's cooperation in carrying out
demonstrations with encouraging results in subsequent years. By conducting front line demonstration of proven
technologies, yield potential of rapeseed-mustard crop could be enhanced with increase in the income level of the farming
community.
