The farm-specific technical efficiency of wheat cultivation in Haryana at the aggregate and disaggregate levels has been studied using stochastic frontier approach. A high degree of technical inefficiency in wheat farming has been reported, which is due to factors under farm’s control. It has been argued that wheat-cultivating farms in the state can increase their production by 27 per cent without increasing the quantity of inputs, i.e. just by way of realizing efficiency. The estimates of technical efficiency have indicated that small-size farms are more efficient than medium- and large-size farms, negating thereby the myth that large-size farming is more profit/business-oriented.
