Results of previous studies on the energy inputs for winter wheat, spring barley, grain maize, peas, silage maize, Medicago sativa and sugarbeet are summarized. Mineral fertilizers and FYM accounted for 55.4% of supplemental energy input, harvesting and postharvest procedures for 17.6%, sowing and seeds 13.6% and soil cultivation 9.4%. An evaluation for 1976-87 gave high energy inputs for grain maize (30.24 GJ/ha), sugarbeet (37.74 GJ), and low inputs for spring barley (18.39 GJ), peas (14.16 GJ) and Medicago sativa (13.70 GJ).
