Abstract
Krishi Vigyan Kendra conducts cluster demonstrations every year as per target assignedby ICAR. The study evaluates impact of 300 demonstrations on mustard crop in 120hectare area conducted by KVK Sirsa since 2015-16 to 2017-18 in different villages of thedistrict. The extension gaps in technologies were identified through farmers meetings andgroup discussions with the farmers. The findings indicated significant increase in the averageyield of demonstrated plot (15.13%) over the farmer’s practice plot of mustard crop. Averageyield of demonstration plots was recorded higher by 18.18 per cent, 14.09 per cent and13.13 per cent in years 2015-16, 2016-17 and 2017-18, respectively. The extension gapwas 4.0 q/ha, 3.10 q/ha and 2.89 q/ha while technology gap was 2.0 q/ha, 2.90 q/ha and2.11 q/ha during consecutive years respectively. During these three years, yield increase indemonstration plots expressed as additional income over check plots accounted for Rs.7670/ha, Rs. 12350/ha and Rs. 11590/ha respectively during various years.
