Assessment of Improved Production Technologies of Indian Mustard (Brassica Juncea) Through Frontline Demonstrations in Real Farming Situation in NCT Delhi

India is ranked 3^rd after Canada and China sharing about 11.0 per cent of the global rapeseed-mustard production (72.41 mt) and 24.7 per cent and 29.4 per cent in terms of area and production, respectively, of oilseeds in India during 2018-19. Mustard is one of the most important oilseeds crop in India, which plays a major role in supplementing the income of small and marginal farmers. One of the major constraints of traditional mustard cultivation is low productivity due to non adoption of recommended package of practices and improved varieties. To replace this anomaly, Krishi Vigyan Kendra, Delhi had conducted cluster frontline demonstrations at selected farmer’s fields in 2018-19 and 2019-20 in rabi season. Cultivation practices comprised under CFLD viz., use of improved varieties i.e. RH 749 and Giriraj, line sowing, seed treatment, INM and IWM. During first year (2018-2019) of experimentation rabi season was deficit to rainfall. The average yield of mustard varieties RH-749 and Giriraj were 23.8 q/ha and 21.8 q/ha respectively, under demonstrated technology at farmer’s fields as compared to local practice (19 q/ha). In 201920 second year of experimentation rabi season received good rainfall during crop duration but higher rainfall occurred at crop maturity stage result average yield of demonstrated technology reduced as compared to first year 2018-19. The higher yield (21 q/ha) was reported of mustard variety Giriraj followed by RH 749 (20.20 q/ha) over local practice (18 q/ha). In both the years of experimentation, average mean yield of RH 749 and Giriraj was found higher as compared the local practice. Maximum gross return Rs. 83300/ha and Rs. 79781/ha, net return Rs. 59730/ha and Rs. 56271 and B- C ratio 2.5 and 2.4 was reported under demonstrated technology at farmer fields as compared to local practice in both year of experimentation.
