Abstract
A field experiment was conducted during 2004-06 to study the effect of combined application of inorganic fertilizer and organic manures on yield, nutrient utilization of jute (Corchorus olitorius L.) along with soil fertility. Substitution of 25% N through water hyacinth compost or farmyard manure in recommended dose of NPK recorded significantly higher fibre yield (2.63, 2.62 tonnes/ha) over the 100% NPK treatment. Maximum N and K uptake (68.22 and 174.41 kg/ha) were observed when 25% N was replaced by water hyacinth compost while maximum P uptake (31.33 kg/ha) was recorded with 50% substitution of N through farmyard manure. Post-harvest soil analysis revealed that integrated nutrient management with water hyacinth compost enriched the fertility status of the experimental soil. Thus, substitution of chemical N-fertilizer to the tune of 25% through water hyacinth compost or farmyard manure increased the fibre productivity in jute and also maintained the fertility status of the soil under Aquic Ustifluvent.
