Indian mustard is predominantly cultivated in Rajasthan, Uttar Pradesh, Haryana, Madhya Pradesh and Gujarat it is also grown under some non- traditional area of south India including Karnataka, Tamil Nadu and Andhra Pradesh. It is cultivated both under irrigated (79.2%) and rain fed (20.8%) condition. Being more responsive to fertilizers, gives better return under irrigation condition. Use of organic manure not only helps to sustain crop yield but International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 12 (2019) Journal homepage: http://www.ijcmas.com The present investigation was carried out during winter season of 2016-17 at ICAR-Directorate of Rapeseed and Mustard Research, Bharatpur, Rajasthan to evaluate the effect of herbal extracts on growth, economic feasibility, yield and yield attributes of Indian mustard (Brassica juncea L.). The experiment was laid out in randomized block design with four treatments and five replications, viz. herbal extracts, RDF + one irrigation, RDF + KNO 3 spray and Control. Results revealed that maximum plant leaves (49.6), GMR (₹ 92423), NMR (₹ 61148) and B:C ratio (2.96) had with treatment receiving RDF + one irrigation. The yield and yield attributes; main shoot length (86.3cm), seed weight/plant (44.06 g), dry weight/plant (158.29g) and yield (2640 kg/ha) were highest under the treatment of RDF+ one irrigation as compared to other treatments. This study indicated that application of recommended dose of fertilizers with one irrigation at 65 days after sowing was more beneficial in terms of getting higher yield and economic returns in climatic conditions of Rajasthan.
