FLD: An effective approach to improve the production potential of groundnut in Guntur district of Andhra Pradesh

摘要

Cluster Frontline Demonstration (CFLD) is a unique approach to demonstrate the production potential of newly released technologies on the farmers' fields. The Rrishi Vigyan Kendra, LAM, Guntur conducted the Cluster Frontline Demonstration (CFLDs) on oilseeds from 2016 to 2019. The KVK had organized 150 CFLDs on Groundnut (Arachis hypogaea L.) in five villages viz., 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. The highest average yield of 40.25 q ha-1 was recorded in the groundnut variety Kadiri 7 Bold, while the lowest average yield was 22.5 q ha'1 (Kadiri 6) with 12.9 and 12.4 per cent increases in yield, respectively. Extension gaps were observed as 3.9, 4.6, and 3.6 in Kadiri 6, Kadiri 7 bold and Kadiri Haritandra. The technology index ranges from 9.75 to 19.6 in demonstrated groundnut varieties in the CFLD programme. There was asignificant 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%) in Kadiri 6, Kadiri 7 bold and Kadiri Haritandra groundnut varieties, respectively. Impact on the adoption (percent change) was prominent in the case of Kadiri 6 (820%), Kadiri Haritandra (533.3%), and Kadiri 7 bold (90.9%) because of their yield potential, crop management practices followed by the farmers suggested by KVK scientists through CFLD. A maximum (48.6%) number of respondents are highly satisfied with the services rendered through CFLD. The Local variety of groundnut variety TAG-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 the transfer and application of agricultural technologies on farmers' fields.
