Evalution of front line demonstration trials on barley in Dausa district of Rajasthan

The study was undertaken to investigate the impact of front line demonstration on Barley. A total of 134 demonstrations having the similar number of traditional practices or local check were conducted in 70 ha area in eleven different village in Dausa district of Rajasthan Yield of front line demonstration trials and potential yield of the respective variety and year were compared to estimate the yield gap which were further categorized into technology and extension gaps. Technology gap was found highest (1530) in case of Rd-2552 at village Dubbi in 2009–10 and lowest (330) of RD-2660 at village Reta in the year 2008–09. Technology index shows the feasibility of the evaluated technology on the farmers’ fields’. The lower the value of the technology index more feasibility of technology. Technology index was highest i.e. 44.61 per cent at village Dubbi in the year 2009–10, and lowest 7.06 per cent at village Reta in 2008-9. The study indicated that average per cent increase in grain yield was 15.05 (558 kg/ha) and straw yield 11.15 (504 Kg/ha). On the basis of present status of area of Barley in Dausa district (6825) farmer can get 3640 metric tons additional production which is essential fulfillment demand and supply gap. On the basis of net returns (Rs/ha) of various front line demonstrations on Barley in different years, the highest percent increase were found 30.94 per cent at village Bhadoli in year 20056 with the variety of RD-2552 followed by 28.58 per cent at village Lawan in year 2008-9 with the variety RD-2552. Across the years front line demonstrations were found higher productivity ranging from 4.93 to 20.92 per cent and higher B: C ratio from 2.24 to 2.84. Front line demonstrations shows in respect of per cent increase of yield and B:C ratio is sufficient for increasing production of Barley and increasing living standard of farmers community of Dausa district. The study reveals that overall per cent increase in net returns was 21.72(Rs 5250/ha).
