The paper deals with subsequently effect of ameliorative tillage on the dynamics of some important productive morphology and productive characteristics in winter wheat. The trial was carried out at the Maize Research Institute Zemun Polje experimental fields in Krnjesevci near Belgrade, Serbia, on meadows chernozem soil type during 2009/10. The following ameliorative and conventional tillage systems were included in investigation: 1) Ameliorative tillage system includes new types machines for field systematization-scrapers (USM 5) in autumn, drainage plow on the depth 60-80 cm, and sub-soiling with heavy vibratory sub-soiler VR 5 on 30-35 cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing; 2) Control variant without ameliorative measures. The following morphological and productive properties of winter wheat were studied: root biomass, stalk height, head, ear number, and grain yield. Ameliorative tillage systems had subsequently effects for all investigated morphological properties on this heavy soil type. Many of them are important for productive properties were statistically significant compared with control. Ameliorative tillage system increase significantly grain yield of winter wheat kg/ha compared with control.
