Data were collected from 120 farmers across 12 villages using a pre tested interview schedule.

Results revealed that both systems were perceived as moderately effective and z value of 3.43 reveals that there is a significant difference was observed, with public services being more effective in advisory roles and private services are effective in timely input delivery. A collaborative approach integrating public and private extension services carries strong policy and extension implications, strengthening institutional linkages and promoting wider technology adoption among oilseed farmers.
