Abstract
A field experiment was conducted at the Regional Agricultural Research
Station, AAU, Nagaon, Assam during 2005 and 2006 under rainfed conditions to study
the effect of combined application of chemical fertilizers, bio-fertilizer and FYM on
soil nutrient status, fibre yield and mineral nutrition of tossa jute. Application of 50%
reduced dose of N and P fertilizer along with inoculation of seed with bio-fertilizer
(Azotobacter and PSB) produced similar fibre yield and gave higher net return, B:C
ratio and also improved soil nutrient status as compared to application of 100%
recommended NPK fertilizer. Similarly, addition of FYM @ 3t/ha along with 50%
recommended NP fertilizer and bio-fertilizer had further increased the fibre yield ,
income and soil nutrient status as compared to application of 100% recommended
NPK fertilizer along with FYM.
Keywords: Chemical fertilizers, bio-fertilizer, FYM, fibre yield, nutrient management.
