Abstract: A field experiment was conducted at Uttar Banga Krishi Viswavidyalaya, Pundibari, Coochbehar, West Bengal during 2012 and 2013 for assessing the seed yield performances of some olitorius jute varieties under different fertilizer doses. The experiment was laid out in a two-factor Randomized Block Design (RBD) with four varieties of olitorius jute  viz., JRO-524,JRO-8432, JRO-204 and S-19 under three  levels of fertilizer application, i.e.,  N-P2O5-K2O @ 20:10:15,40:20:30 and 60:30:45 kg ha-1. It was revealed that among the varieties JRO 8432 performed better in terms of highest no. of primary branches (5.96), no. of capsules per plant (48.92) and seed yield (8.07 q ha-1) with highest net return (Rs. 34828.26 ha-1)  and benefit: cost ratio  (1.98). Increase in fertilizer dose from 20:10:15 to 40:20:30 resulted in significant increase in seed yield for all the varieties but further incremental fertilizer dose did not result in significant yield increase.
