Variation in energy consumption in production of wheat–maize with varying altitudes in hilly regions of Himachal Pradesh, India

Availability and consumption pattern of energy and constraints in its proper supply and management for crop production was studied in wheat–maize cropping system in selected hilly rural villages located at different altitudes of Himachal Pradesh in Western Himalayas. The information was collected from 90 farmers drawn from nine villages, three each from three selected altitudes using two-stage random sampling. The average values of energy consumption for wheat crop in low and high hills were, respectively, 41.68 and 110.8 MJ/ha and those for maize crop were, respectively, 43.43 and 81.33 MJ/ha. The productivity of wheat crop ranged from 1077 to 1840.9 kg/ha and for maize crop from 1108 to 1573 kg/ha, in low and high hills, respectively. The major constraints in the proper use of energy in crop production were the uncertain supply of different inputs due to difficult and undulating terrain, poor land holdings and non-availability of suitable technologies. The introduction of small powered equipment, precise use of seed and fertilizer and proper management of irrigation water were recommended for efficient energy use and better crop productivity.
