Cluster Frontline Demonstration (CFLD) is a unique approach to demonstrate the production potential of newly released technologies on the farmers’ fields. The Krishi Vigyan Kendra, LAM, Guntur had conducted the Cluster Frontline Demonstration (CFLDs) on oilseeds during 2016 to 2019. The KVK had organized 150CFLDs on Groundnut (Arachis hypogaea) in fivevillagesviz.,Yazilli, Danduvaaripaalem, Pachala Thaatiparru, Kaskarru and Karlapalem of Guntur district. To get the adequate size of the sample, 150 CFLDs beneficiary farmers were selected as the sample for the present study.Highest average yield of 40.25 q/ha was recorded in groundnut variety Kadiri 7 Bold, while the lowest average yield was 22.5 q/ha (Kadiri 6) with 12.9 and 12.4 percent increase in yield respectively. Extension gap were observed as 3.9, 4.6 and 3.6 in Kadiri 6, Kadiri 7 bold and Kadiri Haritandra. Technology index ranges from 9.75 to 19.6 in demonstrated groundnut varieties in CFLD programme. There was a significant increase in area from 25 to 230 ha (increased up to 205 %), 10 to 110 ha (increased up to 100 %), 30 to 190 ha (increased up to 160 %) area in Kadiri 6, Kadiri 7 bold and Kadiri Haritandra groundnut varieties respectively. Impact on adoption (per cent change) is prominent in case of Kadiri 6 (820 %), Kadiri Haritandra (533.3%) and Kadiri 7 bold (90.9 %) because of their yield potential, crop management practices fallowed by the farmers suggested by kvk scientists through CFLD. maximum (48.6%) number of respondents highly satisfied with the services rendered through CFLDThe Local variety of groundnut varietyTAG-24 was replaced by improved varieties developed by ANGRAU, Andhra Pradesh such as Kadiri-6, Kadiri 7 bold and Kadiri Harithandra‘. Thus, it can be inferred that CFLDs is an effective extension intervention to demonstrate the production potential of improved technologies in Groundnut on farmers’ field. Therefore, it is recommended that the extension agencies engaged in transfer and application of agricultural technologies on farmer‘s field.
