Agriculture involves complex activities, which require the updating of farmers' knowledge and the adaptation of their strategies in order to have economic efficiency. Producers must make decisions regarding the structure of crops adapted so as to cultivate species that bring material satisfaction, but last but not least, adapted to current climate changes and new culture technologies. Corn is one of the crops that bring significant financial results, but the irrigation factor and the genetic material must be taken into account. The aim of this research is to analyze the energy and economic efficiency of a corn hybrid grown without irrigation conditions in the southern part of Romania, in a conventional and ecological technology system. The results highlighted the higher productivity of the conventional variant, 8,200 kg/ha, a higher fuel consumption of 93.4 l/ha compared to the ecological system where 89.9 l/ha were consumed. The energy consumption for obtaining a ton of corn was 0.126 kwh, in conventional culture system and 0.143 kwh for the ecological system. The energy efficiency is influenced by the productions obtained, the conventional system being superior from this point of view, for the P9241 hybrid, for the applied technology and for the pedoclimatic conditions of the respective area.
