Two frontier production functions were applied to different categories of wheat growing farmers in Punjab. The technical efficiency for each category of farmer was determined. Actual use of various forms of energies in wheat production were compared with the frontier energy used on different categories of farms. From the study, it was concluded that large farmers used energy in the best possible way to achieve maximum yield. Therefore, steps should be initiated to rationalize the use of various forms of energies in wheat production so as to improve the efficiency of marginal, small and medium size farmers. Extension efforts should address the problem of energy conservation explicitly.
