Concept:Jute is a natural fibre obtained from the stem of jute plants.
It is called the "golden fibre" because of its shiny golden colour.
Explanation:Jute fibre comes from the bark of white jute (Corchorus capsularis) and tossa jute (C. olitorius).
It is an annual crop, taking about 120 days to grow during the rainy season.
Jute thrives in tropical lowland areas with 60% to 90% humidity.
It is a rain-fed crop and requires little fertilizer or pesticides.
In India, jute is mainly grown in West Bengal, Assam, Bihar, Orissa, Uttar Pradesh, Tripura, and Meghalaya.
