Abstract: A field experiment was conducted at Defence Institute of Bio-Energy Research (DRDO) HQ Haldwani Project Site Military Farm - Mhow, Indore during the winter (rabi) season of 2010-11 and 2011-12 to study the effect of nitrogen dose and its scheduling on productivity and economics of Camelina sativa. Application of 150 kg N/ha, being at par with 120 kg N/ha, significantly recorded highest seed yield (858 kg/ha) and oil yield (292 kg/ha) of Camelina sativa over 60 and 90 kg N/ha. There was no difference in benefit-cost ratio (0.8) either with the application of 120 or 150 kg N/ha. The crop under three equal splitting (¹⁄з as basal + ¹⁄з at 25 DAS + ¹⁄з at 50 DAS) of N significantly recorded highest seed yield (812 kg/ha) and oil yield (288 kg/ha) over other splits viz., ½ N as basal + ½ N at 25 DAS, ½ N as basal + ¼ N at 25 DAS + ¼ N at 50 DAS. Application of three equal splitting of N recorded 15.1per cent increase in yield over two equal splitting of N with a benefit-cost ratio of 0.8. Thus application of 120 kg N/ha in three equal splitting proved effective in yield enhancement and economical for growing Camelina sativa in Malwa plateau regionof Madhya Pradesh, India.
