The aim of study to examined the operation-wise and source wise energy use in wheat and rice crop production. Present study was conducted in four districts of Haryana namely Kurukshetra, Karnal, Kaithal and Sonipat, which are situated at the bank of Yamuna canal and comes under agro climatic zone-1. In this study total 1080 farmers from 120 villages in different categories (360 from each group) were interviewed and information on various input in wheat and rice crop production was collected during winter and rainy seasons consecutive two years i.e. 2018-19 and 2019-20. Based on the collected information, all the cultural practices in wheat and rice crop production were identified and converted into energy by using standard energy equivalents. Results showed that total operation-wise energy expenditure by large, medium and small farmer's was 43693.82, 42557.21 and 41915.70 MJ/ha respectively in rice crop production. In case of wheat crop cultivation total operation-wise energy consumed by large, medium and small farmer's was 26472.74, 26576.39 and 25644.18 MJ/ha respectively. In both the crop production irrigation and fertilizer share more than 75 % of the total energy. Fertilizer alone accounted approximately 40 % 0f total energy followed by irrigation and it was also estimated that large group farmer's consumed more energy as compared to medium and small categories farmers in cultivation of rice and wheat crop. Total source-wise energy expenditure by large, medium and small farmer's was 39402.40, 36579.49 and 36332.21.70 MJ/ha respectively in rice crop production. In case of wheat crop cultivation total source-wise energy consumed by large, medium and small farmer's was 19969.47, 20486.03 and 20180.73 MJ/ha respectively. From the study it was concluded that energy consumption has a positive relationship with the yield.
