Yield of Jute as Influenced by Continuous Cropping and Manuring over Eight Years in a Fixed Rotation and Layout

Plotwise assessment of jute fibre yield and changes in some available nutrients have been reported after eight years of intensive cropping and manuring in an annual rotation of jute-rice-wheat. All the treatments recorded significant increase over control each year. The increase in fibre production due to 100% of the recommended NPK dose over 50% NPK was significant since the inception of the field experiment. No significant difference in the overall mean level of fibre yield was seen from the 2nd to 8th crop but most of the treatments showed a positive trend in yield over the years. Due to continuous cropping and manuring for a period of eight years the soils became enriched to some extent in available nitrogen, phosphorus and potassium in the respective nutrient treated plots. Micronutrient status remained more or less unaltered. The plots receiving sulphur bearing fertilizers showed higher build up of available sulphur in the plough layer.
