Mustard stands in second place among oil seed crops of India. The productivity of mustard in India is the lowest than the major rapeseed/mustard growing countries. Use of low productive traditional mustard varieties and poor management practices are the major constraints in production. It appears due to non-adoption of recommended high yielding varieties and advance production technologies by the farming community in eastern plains of Utter Pradesh. To replace this anomalous, we had conducted 153 front line demonstrations (FLDs) at farmer fields of various adopted villages by KVK, Deoria. Cultivation practices comprised under FLD viz. improved varieties, thinning, irrigation, date of sowing, seed treatment, spacing, balance use of fertilizers, intercultural operations and plant protection measures showed increase in yield of mustard varieties from 22.2 to 43.7% over farmers practice. Maximum net return was increased (78.29%) in Satabdi variety of mustard over farmer practice in the year of 2015-16 and lowest net return was increased in Pusa Mustard 27 (24.74%) compared to farmers practice in the year of 2014-15. The benefit-cost ratio of five years demonstrated technology was higher over farmer’s practices. The analysis of data for extension gap showed that Satabdi had highest gap (631 kg/ha) and Pusa Mustard 27 had lowest gap (210 kg/ha). The higher value of the B:C ratio and extension gap indicates the more feasibly of the technology in eastern plain of Uttar Pradesh.
