Yield gap analysis of black gram under front line demonstration on pulse Kharif programme.

Front-Line Demonstration is the new concept of field demonstration evolved by the Indian Council of Agricultural Research with the inception of the Technology Mission on Oilseed Crops during mid-eighties. The field demonstrations conducted under the close supervision of scientists of the National Agriculture Research System are called front-line demonstrations. The front line demonstration (FLDs) plays a very important role to disseminate recommended technologies because it shows the potential of technologies resulting in an increase in yield at farmers’ level. This study was undertaken in Krishi Vigyan Kendra Mandsaur, situated in Malwa plateau semi-arid region of Western Madhya Pradesh. Total 39 front line demonstrations conducted during 2012–13 to 2014–15 in Kharif season. During these three years (2012–2014), 15 hectares under black gram were demonstrated with improved management practices using improved varieties. Total 39 farmers were closely associated with black gram demonstrations, respectively. During three consecutive years of demonstration it was observed that the demonstration plots were always the higher yielder as compared to the plots maintained by the farmers on their own. On an average, there was an appreciable increase in yield level 43.96%to 51.43% in black gram under demonstration plots. Adoption of improved technology had significant impact on seed yield vis-à-vis yield gaps in black gram. Improved technology enhanced black gram yield from 285 kg to 358 kg/ha compare to farmers practice with an overall increase yield of 46.95 per cent.
