THE PRODUCTION TECHNOLOGIES FOR FIELD ENERGY CROPS
2012
The aim of research was to evaluate the effect of conventional, reduced tillage and no-till technologies and two fertilisation levels on a biomass production for energy use, expressed in yield of dry biomass, energy acquired and indicative price of energy per ha. During 2007- 2009, the maize for silage, winter wheat and triticale was evaluated at the experimental fields of Plant Production Research Center Piesťany. The significantly highest yield of dry biomass was reached for maize for silage - 19.41 t ha -1 with comparison to triticale - 15.39 t ha -1 . Winter wheat reached significantly the lowest yield on the average level of 14.08 t ha -1 . The highest amount of energy acquired (in GJ ha -1 ) was accumulated in maize for silage with 236.99 GJ ha -1 followed by triticale with 159.39 GJ ha -1 and winter wheat with 152.52 GJ ha -1 . Composition of energy has been as follow: winter triticale - 35% composed of ethanol and 65% of straw, maize for silage 100% of biogas, winter wheat - 40% of ethanol and 60% of straw. The conventional tillage (CT) support the
