He also criticised Union finance minister Arun Jaitley over his recent statement that state governments have to fund schemes like loan waivers through their own resources.
"The prime minister is responsible for the current plight and woes of farmers. Modi has failed to implement his electoral promises like awarding better renumeration for crops and hike in the minimum support price (MSP)," the former Union minister told reporters here.
He said the erstwhile Congress-led UPA government under Manmohan Singh had announced loan waivers worth Rs 77,000 crore during its tenure.
He said the country's economic growth has decelerated under the Modi regime.
Recently, farmers in Maharashtra and Madhya Pradesh held protests for their various demands, including a complete loan waiver.
