Introducton Major oilseed producing countries in the world, which are China, Canada, India, the USA, Brazil and Argentna account for 82% of oilseed producton in the world (Reddy and Emmanuel, 2017). The oilseeds account for one- third of the oil produced in India. Suitable agro-climatc conditons favour cultvaton of all nine major oilseed crops (seven edible oils are Sunfower, Rape seed and Mustard, Groundnut, Sesamum, Soybean, Safower, Niger and two are non-edible, Castor and Linseed). The limited scope of bringing additonal area under oilseeds an increased in producton will have to income primarily from land saving to technology lightng (Choudhary and Suri, 2014). Among oilseed crops, mustard (Brassica juncea) is the third Article History RECEIVED on 15 th May 2021 RECEIVED in revised form on 09 th August 2021 ACCEPTED in fnal form on 21 st August 2021 CFLDs, oilseeds, producton, yield, gap, adopton, mustard Keywords: Cluster frontline demonstratons (CFLDs) are the long-term educatonal actvity conducted in a logical method on partner farmer’s feld to show the worth of new technology under micro farming. The present investgaton was carried out during the Rabi season (October to March) of respectve year 2016-17 to 2019-20 under the Natonal Food Security Mission, Government of India. Four hundred thirteen CFLDs were conducted in 165.2 ha area with the farmers and scientsts of KVK. The CFLDs were conducted at adopted ffeen villages of Dholpur district. Cultvaton technology was applied under CFLDs included scientfc interventon. The highest yield was obtained in demonstrated practces (DP) with an average of 2272.00 kg ha -1 as compared to farmer practce (FP) with an average of 1829.00 kg ha -1 . Further, an average additonal return (` 16,063.6), efectve gain (` 14,335.8), net return (` 64,512.1 ha -1 ) and beneft-cos rato (3.49) were found in the DP as compared to farmer practce. An average occurrence of Alternaria blight, white rust, stem rot, aphid were recorded 27.44, 5.93 and 14.85 and 25.05, respectvely showed in DP as compared to farmer practce. An average extension gap, technology gap and technology index between and was noted 443.0 kg ha -1 , 234.75 kg ha -1 and 10.39%, respectvely. The results indicate that the use of scientfc interventon under CFLDs to increase the producton and proftability of Mustard.
