Abstract: Average physical inputs in maize cultivation in three districts of Haryana (North India) have been transformed into energy units and compared with the energy outputs of grain and byproducts. The chief inputs were in the form of farm yard manure (FYM), traditional farm equipment, tractor and fuel, followed by irrigation and chemical fertilizers. Detailed data of physical inputs were collected from 31 individual farm units of Ambala district, ranging from 0.41 to 3.24 ha. Six of these farms showed extremes of size, tractor use, fertilizer application, FYM inputs, irrigation, as well as yields of grain and byproducts. Data from these farms were analysed in terms of energy utilization. Energy use efficiency ranged from 0.06 to 0.28 for grain and from 0.29 to 1.16 for total produce. The data suggest that grain production can be increased and energy utilization improved by minimizing the use of FYM and by increased use of chemical fertilizers and irrigation.
