The expenses on energy based inputs have registered a phenomenal increase since the 1990s in Indian agriculture. The use of energy intensive inputs is higher on marginal farms than on large farms. In view of increasing share of energy costs, this paper examined the transmission mechanism of increase in energy prices in agricultural commodity markets in India using monthly wholesale price indices during April 1994 to March 2014. In order to assess the effect of deregulation of some petroleum products since April 2002, study period was divided into two sub-periods (April 1994 to March 2004 and April 2004 to March 2014), besides analyzing for full period. The co-integration analysis indicated evidence of parallel movement between prices of energy and all selected agricultural commodities after deregulation, which means higher transmission between crude oil and these commodity prices.
