However, selection of these retting processes depends on the availability of water and the cost of retting process. The water, penetrating to the central stalk portion, swells the inner cells, bursting the outermost layer, thus increasing absorption of both moisture and decay-producing bacteria. However, during jute cultivation, jute plants are soaked in water for several days (a process called retting) in order to separate the fibres. Recently a breakthrough in jute retting has been achieved by scientists of ICAR – CRIJAF who have decoded the genome sequences of jute retting microbes by high throughput genome sequencing. However, during jute cultivation, jute plants are soaked in water for several days (a process called retting) in order to separate the fibres. Why the process of retting is needed in process of harvesting jute? [1], Tank retting, by contrast, employs vats usually made of concrete, requires about four to six days, and is feasible in any season.
