The majority of the cropped land in India (65%) is used for food grain crops, with the maximum food grain production expected in the years 2021–22 at 316.06 million tonnes. With the increase in power availability from 0.3 kW/ha in 1961–1962 to 2.76 kW/ha in 2020–2021, the average food grain productivity in the nation has increased linearly from 0.71 t/ha to 2.39 t/ha. India is the world's second-largest producer of wheat. The crop demands a significant input of energy. Direct energy and indirect energy make up the two main categories of the input energy needed for crops. Compared to the Uttarakhand's hilly regions, the Tarai region's agriculture is far more advanced. The cultivable land is about 7.41 lakh ha which is about 14% of total reported area of 56.72 lakh ha. Because of high energy input used in the district of Udham Singh Nagar, the wheat crop average yield is 3.8 t/ha. This paper discusses the energy requirements for growing wheat in the Tarai region of the state of Uttarakhand in the India. Energy equivalence expressed in MJ/ha was used to calculate the amount of energy required for the various activities carried out in wheat production. The average amount of energy used to produce a wheat crop is found to be 24304 MJ/ha and of these renewal energy contributed 2667 MJ/ha & while that of non-renewal energy contribution was 21637 MJ/ha. The highest total energy of 12148.28 MJ/ha is consumed in fertilizer operation and the lowest total energy consumption of 872.98 MJ/ha is observed in plant protection. The energy ratio and energy productivity were found as 6.77 and 0.22kg/MJ.
