Abstract Purpose This study aimed to study the energy use pattern of sugarcane crops, optimize the energy use pattern of an inefficient farmer, and study the opportunities for input energy saving in sugarcane cultivation. Methods The input–output energy in sugarcane cultivation was audited by collecting data from 61 decision-making units (DMUs) using a face-to-face interview with sugarcane growers in Maharashtra state (India). Technical, pure technical, and scale efficiencies for farmers were calculated using the Charnes–Cooper–Rhodes and Banker–Charnes–Cooper models of the data envelopment analysis technique. Results The average total input (EI) and output (Eo) energy for sugarcane cultivation were 146.15 + 11.16 GJ ha−1 and 961.02 ± 83.73 GJ ha−1, respectively. The energy share of sugarcane and sugarcane trash in the total output energy was 843.18 ± 60.4 GJ ha−1 and 91.48 ± 6.5 GJ ha−1, respectively. The energy ratio (ER) and net energy gain of sugarcane cultivation were 6.57 ± 0.57 and 814.8 ± 69.9 GJ ha−1, respectively. The average technical efficiency, pure technical efficiency, and scale efficiency for sugarcane cultivation were 0.74 ± 0.03, 0.97 ± 0.006, and 0.76 ± 0.03, respectively, in the study region. Conclusions The scope for energy saving in sugarcane cultivation was observed to be 19.82% as compared with the actual energy required. If the recommendation of energy saving is followed by inefficient DMUs, a total input energy of 28.98 GJ ha−1 can be saved, maintaining a constant output level of sugarcane yield.

Introduction Sugarcane is one of the oldest cash crops grown in tropical and subtropical areas of the world (Malik et al. 2019). Approximately 60% of sugar worldwide is produced from sugarcane. India is the second largest sugarcane producing
country after Brazil (Malik et al. 2019). The total worldwide area under sugarcane cultivation is 16 Mha, producing nearly 112 MT of sugar. In India, the area under sugarcane crop is approximately 5 Mha, contributing to sugar production of 25– 26 MT with approximately 6.5 MT of sugarcane trash every year. In India, 530 sugar mills process the produced sugarcane
