To another query, the chief minister said that only the Union government was authorised to waive the loans of farmers towards the banks, adding that the state government has hardly any role in it.
Badal said he had been regularly pleading for making all-out efforts to make agriculture a profitable venture.
Badal said that on its part the state government was providing free power worth Rs 5000 crore annually to the farmers besides ensuring Health insurance and an interest free crop loan worth Rs 50,000 to them.
Criticising the Aam Aadmi Party (AAP) and Congress for defaming the state, he said that both these anti-Punjab forces were "tarnishing" the image of state by branding the hard working and resilient Punjabis as "drug addicts".
"Earlier the Congress levelled the Punjabis as terrorists and now both these parties were branding them as drug addicts," Badal alleged.
