ENERGY EXPENDITURE IN TRITICALE CULTIVATION WITH DIFFERENT MICROELEMENTS FERLILIZATION TECHNIQUE

The purpose of study was determination the energetic expenditure of triticale cultivation at different fertilization technique. There were calculated expenditure of treatments, natural resources, materials, durable means and equivalent of real work. It was showed, that the sum of the total energy expenditure in triticale cultivation was from 16723.2 to 21864.8 MJ ha –1 . The lower expenditures were with soil fertilization technique without objects with higher manganese dose (10.0 kg ha –1 ) and with copper, zinc and manganese applied together at nitrogen dose 80 and 120 kg ha –1 independent with microelement dose. The higher sum of total energy expenditure was with all microelements applied together before triticale sawing (to soil) depend on ferlilization before sawing with copper, zinc or manganese. There was not significant different in the same case with spray application of studied microelements. In the energy expenditure structure of triticale cultivation the higher participation (64.4–71.7%) was shoved with raw and materials, the lower (17.2–21.5% and 8.9–11.4%) with immediate energy carriers and exploitation expenditure and, the lowest (2.2–2.7%) with human work.
