Abstract


The experiment was placed on chromic luvisol at the Moara Domnească Teaching Farm belonging to the University of Agronomic Sciences and Veterinary Medicine of Bucharest. The soil tillage experimental variants were: a1 - ploughed at 20 cm in depth (control - conventional system SC); a2 - chisel ploughed at 20 cm in depth; a3 - chisel plough at 40 cm in depth; a4 - disking at 10 cm in depth (minimum tillage system MTS). The wheat varieties analysed were: four wheat varieties b1 - Dropia;  b2 - Apache; b3 - Jindra; b4 - Altigo, and two hybrids b5- Hyspeed; b6-Hylux. Basic tillage was performed during the last decade of September. Sowing density was about 480 g.g./m2 in varieties and 240 g.g./m2 in hybrids. Fertilization was applied at a N140P70K70 kg rate a.s./ha, plus  foliar fertilization based on  Hortifor 2.5 kg/ha. Climatic conditions for 2014 were favourable for wheat crop, as they allowed plants to show their yield potential. Grain yield ranged between 7,640 kg/ha in the disc tillage Dropia variety and 9,620 kg/ha in the Hyspeed hybrid under minimum soil tillage conditions (chisel 40). Yield and crop parametres vared depending on the wheat variety grown. The number of yielding sprouts and grain weight per spike in hybrids were higher than in the varieties. Minimum soil tillage (chiselling) results in wheat yields closer to the conventional variant.
