The consumption of maize (Zea mays) in Indonesia is a direct consumption by household level, allocation for feed, seedling and processed into food industry and non food industry. Corn production in Indonesia reached 19,612,435 tons with the highest contributor of production of East Java as much as 6.131.163 tons or 31.2% of the total national maize production. The location of the research in Maindu Village, Montong District, Tuban Regency, East Java Province. The objectives of this research are: (1) To analyze the level of farmer's technical efficiency (2) To analyze the level of peat allocative efficiency (3) to analyze the level of farmer's economic efficiency. The method of analysis used is Data Envelopment Analysis (DEA). The results obtained are the average level of technical efficiency is quite high at 0.833 or 83.3%. The number of farmers who are categorized as very efficient (> 0,843) counted 34 farmers (53,9%). The number of farmers who operate on the scale of CRS (Constant Return to Scale) 22% (14 farmers) and the operating IRS (Increasing Return to Scale) 68% (43 farmers) while operating on the scale of DRS (Decreasing Return to Scale) as much as 10% (6 farmers). The average value of farmers' allocative efficiency is quite high at 0.746 or 74.6%. Number of farmers included in the category of highly efficient Allocative (> 0.871) as many as 11 people (17.46%). The average value of economic efficiency is quite low at 0.623 or 62.3%. The number of farmers included in the category is very efficient economically (> 0.825) as many as 11 people (17.46%)..
