The researches carried out in the Caracal Plain do confirm the presence of positive relation between the tillage, the sunflower yield and the energy consumption no matter the irrigation regime and climatically condition of the year. There have been made determinations on the fuel consumption (l/ha), the machinery productivity (ha/hour) to the tillage, the seed yield at 11% moisture, energy consumption (Mcal/kg of product). The results of fuel consumption with the three in average after measuring and timing within the researched period show differences between them.
