He said an "artificial crisis" was created in the states where the Congress government was formed, and the matter was being investigated.
"It seems that urea racks meant for Rajasthan and Madhya Pradesh were diverted to Haryana which led to the crisis. It was an artificial crisis created in the states where governments changed," Gehlot told reporters outside the Raj Bhawan.
Gehlot said instructions have been given so that such urea crisis is not faced in any of the districts.
The chief minister said such incidents never occurred during (his earlier tenure of) 2008-2013.
"The prime minister had quoted in a public meeting that urea was distributed under police protection during the Congress rule. In fact, in past five years of BJP government, urea crisis had occurred, farmers were lathicharged. How could he (Modi) make such a statement?" he said.
