The present paper covers economic analysis (concerning energy and cost aspects) of rye production technologies employing different cultivars, sowing dates, NPK fertilisation, microelements nourishment and weed control. Intensive production of rye using a hybrid cultivar, early sowing and NPK fertilisation at 176 kg·ha-1 produced 46% higher yields compared to extensive technologies involving open pollination cultivars and low fertiliser rates. The highest energy consumption in winter rye production was caused by NPK fertilisation. Intensive technologies were less energy-effective than extensive methods. The direct costs of growing 1 ha of rye in extensive technologies equalled 2.2 2.9 t grain. In intensive technologies direct costs were returned at yields as high as 3.9 4.6 t per ha. The yield value increment resulting from more intensive production methods did not cover completely the increase in direct costs.
