Series of on-farm sunflower frontline demonstrations (FLDs) were conducted in Kharif and winter seasons in five districts of North-Eastern Karnataka from 2007 to 2019. These demonstrations were conducted over 419 farmer fields each having minimum of one acre of sunflower production. Collected data of FLD’s and farmers practice were analyzed in terms of yield advantage, monetary benefits and assessed the yield gap and extension gaps. Results indicated that there was huge gap in grain yield gain (11.0 to 35.2%) across improved components demonstrated over existing farmers practice. It was also resulted additional monetary benefits (Rs. 2300 to 6800/ha) in both the seasons. Maximum yield improvement was noticed by weed management, intercropping with pigeonpea and groundnut, management of pests, alternaria, necrosis and powdery mildew. It was indicated that sunflower yield improvement possible by implementation of improved technologies.
