Maximization of crop yield per unit of cultivated area especially for the crops under the thread of tough competition and minimization of energy inputs require specific concentration on energy use patterns and their amounts. Sufficient information is not available on energy use pattern for various crops for the Cukurova region which is one of the most important agricultural centers in Turkey. This research examines the energy use pattern and energy input-output analyses of first crop maize widely grown in Cukurova region. After analyzing the questionnaire data of 50 farms, maize farm of 12 ha which shows the general maize production characteristics of region were selected as a sample farm to collect the data related to operational inputs and energy sources. Acording to the results, maize production consumed a total of 31546 MJ ha(-1) depending mainly on fertilizer and fossil fuels. The fertilizer application evaluated in material energy was found to be the highest energy source in total inputs with the share of 63.4%. Diesel and machinery energy had the shares of 23.3% and 5.9%, respectively. Diesel and oil energy requirement for irrigation and tillage-seedbed preparation were 2868 MJ ha(-1) (39.1%) and 2626.7 MJ ha(-1) (35.8%), respectively. Energy ratio, total energy productivity and net energy gain were 4.76, 0.29 kg MJ(-1) and 306,170 MJ, respectively.
