The aim of the present work was to carry out an energy evaluation of different spring rye cultivation technologies at varied post-harvest cultivation and location. The analysis of energy effectiveness included unit energy consumption cumulated in production means. Detailed analysis of energy effectiveness was carried out including yield energetic value. Winter rye basic yield was transformed into dry matter yield and then expressed in GJ. Next, energy outlays for operations carried out in particular technologies of rye cultivation were calculated by expressing the level of outlays cumulated in production means depending on the actual use of mineral fertilizers, sowing material and plant protection agents. Labour and production means outlays as well as fuel consumption were transformed into GJ using indices of energy consumption applied in energetic plant production calculus. The index of energy effectiveness, final effectiveness and level of energetic intensity were the final measures of analysis and energetic evaluation. Measures of production outlays and effects taken into account in the current work made it possible to analyse energy consumption of different spring rye cultivation technologies. Fertilizers accounted for the largest amount of energy (56.4%). All the cultivation practices represented 29.4% of energy on average. Replacement of summer ploughing with disking or skimming reduced energy outlays by 4.6 and 1.2%, respectively, whereas replacing skimming with disking reduced energy outlays by 3.3%. Differences in outlays introduced with varied cultivation operations resulted from different duration of work and fuel consumption. The highest yield effectiveness was obtained for treatments on which disking was applied before catch crop sowing and without catch crop ploughing under (3.5) and when tancy phacelia was sown (3.4).
