abstract
Demonstration on toria under Cluster Frontline Demonstration on oilseed was conducted in all the six agro climatic zones of Assam covering 26 districts during the last five consecutive years i.e. 2018-19 to 2022-23. A total 6923 Cluster Frontline Demonstrations covering 2877.70 ha was conducted in Assam during the study period. Maximum number of demonstrations were conducted in Lower Brahmaputra Valley Zone followed by Upper Brahmaputra Valley Zone whereas, Hill Zone has conducted minimum number of demonstrations. Among the six agro climatic zones, toria recorded highest demonstration yield in Central Brahmaputra Valley Zone followed by Upper Brahmaputra Valley Zone while minimum yield was observed in Hill Zone. In terms of gross and net return, maximum were obtained in Central Brahmaputra Valley Zone followed by Barak Valley Zone. In all the zones, yield of toria under demonstration was higher than that of local check throughout the study period. The pooled average yield of toria in Assam over five years period under demonstration was 9.03 q/ha which was 42.13% higher than the local check. Higher yield of toria under demonstration resulted in more income. The average gross and net return of toria in Assam under demonstration were 43224.00 ?/ha and 22322.00 ?/ha respectively with average B:C ratio of 2.06.
