Cluster Front Line demonstrations (CFLDs) is a unique approach where, the scientists are directly involved in planning, execution, and monitoring the demonstrations, so there is a direct connection between researchers and farmers. The present study was conducted to assess the impact of frontline demonstrations of sunflower crop in the Prakasam district of Andhra Pradesh state. Sunflower is a highly nutritious oil seed crop and is widely appreciated as health food as well as high return crop. The production potential of demonstration and economic benefit can judge by conducting the cluster Front line demonstrations (CFLDs) at farmers fields. Study revealed that improved cultivation practices comprised under CFLDs viz., recommended hybrids, seed rate, timely sowing and plant protection technology resulted in increase in yield in gram crop over the check plots. The improved technologies gave higher yields and recorded a yield of 1452 and 1380 kg ha-1 sunflower yield during 2019-20 and 2020-21, respectively which was 38.28 and 45.26 percent higher compared to prevailing farmers practice. Average seed yield under improved practice (IP) (1416 kg ha-1) was 41.60% higher over farmer’s practice (FP). The technology gap and extension gap were in the range of 48 to 120 kg ha-1 and 402 to 430 kg ha-1 respectively. Technology index value varied from 3.2 % to 8.0% during the study period. The benefit cost (B: C) ratio was 2.23 to 2.84under demonstration, while it was 1.62 to 1.51 under control plots. The average B: C ratio under IP (2.53) was 40.5% higher over FP
