Answer:
sharecropping
Step-by-step explanation:
Sharecropping is a system of tenancy agriculture . In it a landowner gives a portion of his land to a labour for the purpose of raising crop . In return , he gets a share of crop raised by him for free.
After the civil war , former slaves were in search of jobs . Due to depression and absence of credit system ,they went into this deal of sharecropping with whites . They also borrowed heavily for getting seeds and fertilizer. Landlords charged high interest rate for that which led them to debt-trap. Landowner also put condition like selling the yield on their condition at pre-specified cheap price.
