BKU (E) General Secretary Sukhdev Singh alleged that both Punjab and central government was responsible for "increasing number of farmers' suicides".
The protest was launched yesterday.
BKU (Ugrahan) president Joginder Singh and BKU (Ekta) General Secretary Sukhdev Singh alleged most of the farmer suicides were due to the support given to money lenders by the government.
The leaders said Punjab government had betrayed farmers by not implementing their demands.
Sukhdev said the protesting farmers would intensify their agitation after five days if the government failed to address their problems.
