Abstract

The aim was to gain knowledge on the impact of different ways of tillage and fertilization, on the observed yield forming elements and energy balance of maize grain. Field experiments were carried out in the years 2009-2010 on the experiment  base SUA Lower Malanta. Tillage methods were: O1 - conventional, O2 - reduced, O3 - minimalization. Variants of fertilization: H1 - without fertilization, H2 - balance fertilization, H3 - balance fertilization and with incorporation of harvest remains previous crop.  Tillage did not affect statistically significant none of the monitored harvest-elements. Fertilization statistically significantly affected the number of grains per plant and high significantly WTG and grain yield. Crop year  highly statistically demonstrate the effect on all monitored harvest-elements and grain yield and aboveground phytomass. From the perspective of the development of bio-energy potential is considered as the most favorable balance fertilization with incorporation of harvest remains previous crop. Maize grain responded evaluated different on the selected factors in selected years.
