Mustard is among the oldest recorded spices as seen in Sanskrit records dating back to about 3000 BC (Mehra, 1968) and was one of the first domesticated crops .In India, the mustard - rapeseed is the most important oil seed crop after groundnut accounting around 25 per cent of total oilseed production. It is one of the important oilseed crop of the Indo-gangetic plains. Indian mustard (Rai) cultivation has occupied about 85-90 per cent of total area under cultivation of mustard – rapeseed. The present study was carried out at KVK, Jale, Darbhanga Bihar to know the yield gaps between improved package and practices(IP) under Cluster Font Line Demonstrations(CFLDs) and farmers practices (FP) of rapeseed mustard. The study found, the yield of rapeseed mustard in improve practices (IP) under irrigated condition range from 14.04to15.67, where as in FP it range between9.8to 10.25q/ha. The percent increase in yield IP over FP was recorded in the range of 37.64 to 55.61.The extension gap and technological index were range between 3.84-5.5 q/ha and 30.20percent respectively. The trend of technological gap reflected to farmer cooperation in carrying out demonstrations with on ranging result in subsequent years. The cost benefit ratio was 2.49 and 2.83under demonstration, while it was1.52to 2.0under control plots. By conducting Cluster Front Line Demonstrations (CFLDs) of proven technologies, yield potential of rapeseed- mustard crop should be enhanced to a great extend with increase in the income level of farming community.
