Abstract : Field experiment was conducted for disease management with seven eco-friendly treatments in Corchorus olitorius jute during 2012-2013 under randomized block design (RBD) in three replications with variety JRO-524. The ecofriendly treatment 50% N: P: K + seed treatments with Azotobacter and phosphorus solubilizing bacteria (PSB) @ 5g/Kg+ Trichoderma viride (seed treatment @ 5g/Kg of seed and soil application @ 2Kg/ha at 21DAS) + Psuedomonas fluorescens spray @ 0.2% at 45DAS was found superior with minimum per cent disease incidence (3.46 and 1.43%) as compared to control (13.17 and 4.96%). The second best treatment was found with Farm yard manure (FYM) @ 5t/ha + seed treatment with Azotobecter and PSB @ 5g/Kg+ T. viride (seed treatment @ 5g/Kg of seed and soil application @ 2Kg/ha 21DAS)+ P. fluorescencs spray @ 0.2% at 45DAS and showed 3.61 and 2.0% disease incidence. The treatment with N: P: K @ 60:30:30 and seed treatment with carbendazim 50WP @ 2g/Kg at 45DAS showed 4.56 and 2.10 % disease incidence. Dry fibre yield was highest (30.33q/ha) in the plots treated with FYM @ 5t/ha + seed treatment with Azotobacter and PSB @ 5g/Kg+ T. viride (seed treatment @ 5g/Kg of seed and soil application @ 2Kg/ha at 21DAS) + P. fluorescencs spray @ 0.2% at 45DAS) and it was lowest in untreated control (15.69 q/ha).Variation in yield was attributed due to difference in plant height.
