The origin of indigo in India 


The indigo in India was started at the time of Indus Valley Civilization around 2500-1500 BCE. During the British East India company rule India was the major exported of indigo to Europe. When the cultivation of indigo became very important, the farmers of Bengal and Bihar were forced to grow indigo.

Flow of indigo trade from Indian subcontinent to the world 

 

Around 5000 BCE people started growing a plant called Indigofera tinctoria in India and nearby places. By the 2nd and 3rd centuries, the flow of indigo to Europe started with animals such as oxen, camels and horses. 


During the 16th century the Portuguese found a direct sea route to India. This made the indigo trade easier. Around the 18th century the indigo trade started flowing everywhere. Indigo is being transported to Agra to Lahore and Kabul and then to Egypt and the East by Land routes. Sea routes carried indigo from Indian ports such as Surat, Dhaka, Chittagong, Balasore to Europe, Africa, China, Vietnam.

 

Decline of natural indigo 

 

There was a significant decline in natural indigo around the 20th century. This was due to the increase in demand for synthetic indigo; this happened around the 19th century. This made the production of indigo really very important for the economy.

Economic significance of Indigo   

why indigo consider as blue gold

     

  Have you ever thought about why people are mad about colours? Yes,that's Indigo, a blue colour comes from the green plant that’s interesting. In ancient times the rate of indigo was too high like today's gold rate and also the people thought  themselves as the richest person like king or queen whenever they wore indigo-colored clothes. It shows the value of  Indigo. Peoples had fighted and also started revolt for that indigo.So it is considered as “Blue gold” because of the rarity,history,value and culture that it had. 

  Indigo is derived from indigofera plants. It was first used in India ,so it was named indikon, a word that comes from the language of  Greek which means Indian product. In ancient times people used Indigo as a form of money to exchange other goods, because of its value.It took main place in India,Egypt,and Africa textile culture. It’s not only by name it’s also mixed with real gold to write manuscripts like the Blue Quran which is written on Indigo dyed paper with golden letters.

Nowadays also we wear blue every day, it gives a good look for photos. It's also Indigo but that is synthetic.So today we can buy them at an affordable price.Anyhow indigo is always considered as "Blue Gold"


                   


Indigo was once called Blue Gold. Because it was rare. Precious . . . (n.d.). www.google.com. https://share.google/1h9pg8oW6RyE78xVL 




Flow of indigo from production centre to market 

                      

  Do you know how this indigo colour textiles come to the Market? The first step is to cultivate the Indigofera tinctorial L .The sad thing in indigo cultivation is the cost of growing indigo plants is very high that is analysed by sensitivity analysis.We need to reduce the cost right ? One way is to decrease the cost of biomass production and another one is to increase the cost of biomass yield. Also we can utilize the waste that is extracted from the dye like compost, biofuels. The farmers soaked the indigo leaves and it got fermented . Further they mixed it well. The blue colour settled down and finally fried under sunlight. After producing indigo powder it can be exported domestically and internationally.
