Technological and Extension Gaps in Maize Production under Rainfed Ecosystem

摘要

A study was conducted in the district Rajouri by collecting data from 262 front line demonstrations conducted on maize crop by KVK Rajouri for five consecutive years (2012-13 to 2016-17). There was a wide yield gap between the potential, demonstrationand farmers yields in maize mainly due to technology and extension gaps. The results of the study revealed that the average yield of demonstration plots and farmers plot (check) were 24.17 q ha"1 and 17.52 q ha"1 respectively. On overall average bases 38.22 % higher grain yield was recorded under demonstration plots than farmers plot. The technological yield gap and extension yield gap during the study period varied to the extent of 19.70 to 48.20 q ha"1 and 1.58 to 10.30 q ha-1 respectively. The overall technology gap, extension gap, and technology index in maize crop were 35.25 q ha1,6.69 q ha"1 and 58.96% respectively. The yield gap analysis emphasizes the need to educate the farmers through various extension means for adoption of improved agricultural technologies to revert the trend of wide extension gap.
