Sustainable agriculture is an increasingly used concept, as it also includes the inimum or zero tillage technologies. This implies the complete absence of ploughing, disking and other crop aintenance works. This paper presents the mean of the research carried out between 2014-2016 at the Moara Domnească eaching Farm located in the Ilfov County and belonging to the University of Agronomic Sciences and Veterinary edicine of Bucharest. The biological material consisted in several early maize hybrids belonging to the following roups: FAO- 270, 280 (Sunergy, PR39B76), FAO- 340, 380 (Bonito, PR37N01) and FAO- 400, 500, 510 (Olt, Sumbra, 0216). The experimental variants for the soil tillage system were: ploughing 20 cm (control), chiselling 0 cm, chiselling 40 cm, disking 10 cm, disking/ploughing 20 cm, disking/chiselling 40 cm. Production ranged between 886.0 kg/ha (in the FAO 270, 280) and 6626.2 kg/ha (FAO 340, 380), and recorded the highest values of 7034.8 kg/ha n hybrid P0216.
