Abstract: Experiments were carried out in the soil conditions (vertic chernozem) of the Didactic Station from Banats University of Agricultural Sci ences and Veterinary Medicine - Timioara (Timicounty) between 2003-2005. We used two soil-working methods: conventionally technology and no-tillage technology. The experimental device for studies upon the no-ti llage influence was organized as a stationary experience with the following variants: V1 (control): tillage with the plough with a mould bo ard + disk harrow V2: tillage with the disk harrow - two times V3: tillage with the combined rotating harrow V4: tillage with the disk harrow + the combined rotat ing harrow V5: tillage with the disk harrow + soil processing wi th a vibrocultor V6: no tillage On the vertic chernozem from D.S. Timisoara, the determinations carried out upon fuel intake per total technology show certain diffe rences between the variants used. So, under the conditions provided by the classic system, we h ave used 111,10 l/ha (100%) compared to 92,10-98,10 l/ha (82,90-88,30%) in the variants wit h minimal tillage and 80,70 l/ha (72,62%) in the mo tillage variant. The fuel intake analyzed in comparison with the yie ld achieved has the following values: 14,7 l/t under the classic system, 13,2-13, 8 l/t in the variants with minimal tillage system and 12,0 l/t in the no tillage variant. The energy intake for the initiation and maintenanc e of maize crop, according to the classic technology, represents 22,957 Mj/ha. The replacement of the work carried out with the pl ough with a mould board with the no tillage system reduces the energetic input with 15.52%. Within the variants V 4 (η=8,15), V 5 ( η=8,46) and V 6 (η=8,79), the energetic efficiency is bigger compared to the control variant ( η=8,12), meaning that the difference between the energy output and the energy input is superior in t hese variants compared to the control variant. The economic efficiency of the no tillage technolog y in maize crop consists of the achievement of yields similar to those achieved und er the classic system, but with smaller technological costs.
