ENERGY BALANCE EVALUATION OF WINTER TRITICALE PRODUCTION

This study has been carried out to assess the energy efficiency of a production technology used to grow a cultivar of semi-dwarf winter triticale called Gniewko. The research data consisted of the results of a three-year field experiment conducted at the Experimental Station in Balcyny near Ostroda (Poland). Three technologies selected for comparison produced the lowest, medium and highest grain yields. The compared technologies differed in the dosage of nitrogen fertilization and the level of fungicidal control. In all the analyzed technologies, mineral fertilization was the most energy demanding link in the agronomic practice of growing winter triticale. The highest yield technology was markedly less energy efficient than the medium and lowest yield technologies.
