Mustard is the second most important and most prominent winter oil seed crop of India. It is grown mainly in the northern plains of India with some cultivated area in the eastern geography as well. Mustard is a major Rabi season oilseed crop growing in the Datia district of M.P. Front Line Demonstration (FLD) is an applied approach to accelerate the transfer of proven technologies to farmer’s field in a participatory mode with an objective to explore the maximum available resources of crop production and bridge the productivity gap by enhancing the production in national basket. The study was conducted by cluster frontline demonstrations (CFLD) on mustard during 2018- to 2021-22 in six villages (Kalipura, Kakrura, Beekar, Bahadurpur, Uprai, Badonkala, Raruajiwan and Pachokhra) covering 200 farmers and 20 hectors area from two blocks of Datia district of Madhya Pradesh to evaluate the technological interventions, yields and economics. To demonstrate the production potential and economic benefits of improved technologies integrated nutrient management was used on the basis of RDF (80: 40:0:20) kg/ ha NPKS, summer deep ploughing, IPM seed treatment with 1+2 gm carbendazim + thiram and 01 gm. imidacloprid per kg seed and recommended fungicide and insecticide as per need and time. There was an appreciable increase in average yield level from 25.41 to 34.86 per cent mustard under the demonstration plot. Adoption of improved technology had a significant impact on seed yield vis-à-vis yield gaps in mustard. Improved technology enhanced mustard yield from 400 to 600 kg compared to farmers practices, with an overall increase in yield of 29.06 percent.
