What made Swapna sell the cotton to the trader instead of selling at the Kurnool cotton market?

Swapna sell the cotton to the trader instead of selling at the Kurnool cotton market because she is a small farmer and her production of cotton was in small quantity. She did not have money to purchase material requires for to start cultivation so she had taken loan at high interest from the traders under a condition to sell her cotton to him. So now she has to principal loan amount, interest as well as her cotton to the traders.
