Why did the British introduce commercial agriculture in India? How did the production of opium, indigo and sugar shot up the profit margins of the east India Company?

The main purpose of the British East India Company to expand trade in India was through agriculture. Through the cultivation of the opium, indigo and sugar they decided to increase their profits. They asked peasants to grow these crops, and in return, they will get paid. So Company encouraged farmers to grow commercial crops and also helped them with loans and other equipment. They bought these crops at low price from peasants and sold it at higher prices to other European countries. Gradually, they started getting profit with the trade.
