Prime Minister Narendra Modi on Saturday held a video conference with Chief Ministers.
Taking to Twitter, Kumaraswamy wrote, "As the lock down continues, what action plan does the government have to tackle the challenges of ensuring marketing channels for farm produce with timely transport and ensuring uninterrupted supply of essential groceries to towns and cities?"
He later asked the government to act "swiftly and effectively".
"On one hand we see farmers throwing their produce in despair and losing their livelihoods. On the other hand supplies to towns are depleting. This is threatening both lives and livelihoods. The government must act swiftly and effectively," Kumaraswamy tweeted.
"I urge the state government to immediately announce relief package to farmers by way of direct benefit transfer mechsm and purchase all the agricultural produce so as to avoid farmer suicides," he added.
With 40 deaths and 1,035 new COVID-19 cases in the last 24 hours, India on Saturday witnessed a sharpest ever increase in coronavirus cases, taking the tally of the infected people in the country to 7,447, according to the Ministry of Health and Family Welfare.
