Assessment of technology gap and productivity gain through crop technology demonstration in chickpea.

摘要

There is a tremendous opportunity for increasing the production and productivity of chickpea crop by adopting the improved technologies. Total 2450 Crop Demonstrations on chickpea variety RSG-888, BG-372 and GNG-663 were conducted at farmers' fields in district Jhunjhunu (Rajasthan) during five consecutive rabi seasons 2007-08 to 2011-12. On overall average basis, 17.81% higher grain yield was recorded under demonstrations than the farmers traditional practices (check). The extension gap, technology gap and technology index were 168/195 and 221 kg per ha, 867, 725 and 964 Kg per ha and 43.33, 32.95 and 43.82% in variety RSG-888, BG-372 and GNG-663, respectively. Data on technology index reduced from 47.50% (2007-08) to 43.82% (2011-12) exhibited the feasibility of technology demonstration.
