A number of technological innovations for increasing rapeseed-mustard production and productivity have been generated by the research. The farmers have adapted some of them but still there are many which have not reached to the farmers. An important pre-requisite for the adoption and diffusion of innovation which a social system is effective communication of information relating to the innovation involved. Rapeseed-Mustard is an important oilseed crop and contributed around 23.2% of total oilseed production in India having major role in supplementing the income of small and marginal farmers of West Singhbhum district of Jharkhand. One of the major constraints of traditional mustard farming is low productivity due to non-adoption of recommended package of practices, use of imbalance doses of fertilizer and improved high yielding varieties. To replace this anomaly, Krishi Vigyan Kendra, West Singhbhum had conducted frontline demonstrations at adopted farmers’ fields. Cultivation practices comprised under FLD viz., use of improved high yielding varieties, line sowing, balanced application of fertilizers specially inclusion of sulphur and control of mustard aphid through insecticide at economic threshold level showed that percent increase in the yield of mustard ranged from 28.59 % to 40.76% over local check during the course of study from 2005-06 to 2009-10 (4 years). Hence increase in yield over farmers yield was evident which indicated the need of educating farmers through frontline demonstration.

Oilseeds constitute the second largest agricultural commodity in India after cereals accounting for nearly 5% of gross national product and 10% of the value of all agricultural products. Despite the fact that India is one of the leading oilseed producing countries in the world, it is not able to meet the edible oil requirement for its vast population. Among the oilseeds, rapeseed-mustard group of crops occupies prominent position in the country during winter season contributing nearly 21.6% and 23.1% to the total oilseed cropped area and production, respectively (Anonymous, 2007).  Rapeseed-mustard production in our country was 7.10 mt, covering area of 6.6 m ha. Area of rapeseed and mustard in Jharkhand 67000 ha, prodn 33000 tonnes and productivity 5 q/ha in 2008-09 (Anonymous 2008-09) The productivity of rapeseed and mustard in Jharkhand (500 kg/ha) is much below than national (1075 kg/ha) and world average (1635 kg/ha)...
