Impact of cluster front-line demonstration on yield, yield gap and economics of linseed in Bongaigaon district, Assam

Abstract

A total of 196 numbers of cluster frontline demonstration (CFLD) on high yielding variety of linseed (T 397) in 57 hectares of land spreading over seven villages was conducted by Krishi Vigyan Kendra, Bongaigaon, Assam in four consecutive years i.e. 2015 to 2018 to assess the effect of FLDs on bridging the gap between the potential yield and the yield obtained from famers’ practice. It was observed that improved agro-technology substantially increased the yield and returns from linseed crop. On an average, 22.13% increase in linseed production was observed under FLDs compared to farmers’ practice. A technology gap of 2.10 q/ha and extension gap of 1.75 q/ha was observed which reflects the needs for specialized extension methodologies. The technology index that decreased from 22.0% to 20.3% clearly indicated the importance of the technologies demonstrated. The positive effect of various technologies was clearly visible by the higher B: C ratio under FLD plots.
