Study was under taken in Sitapur district of U.P. in central India. This state has record yield potential of the crops but, there is yield gap between farmers yield and yield potential of pulse crops due to unawareness about potential variety(s), use of poor quality and inadequate seed, conventional cultivation practices and poor crop management practices. The yield performance of pigeonpea was studied through front line demonstration in the year 2012-13, 2013-14 and 2014-15. Existing farmers practice was taken as a control for comparison and recommended HYVs of pigeonpea Narendra Arhar-1 (NA-1) along with soil test value based fertilizer application and integrated crop management practices. The forty eight front line demonstrations covering 15.65 ha area were conducted. The study reveals that an average yield of pigeonpea under demonstration plot was fetched 2.24 t ha1 lowest in farmers practices (control plot) 1.53 t ha1 hence, 46.08 per cent yield was increased over control. The average technology gap was recorded 0.76 t ha1, average extension gap 0.71 t ha1 and average technology index was recorded 25.33 per cent.
