Abstract: The effect of different reduced primary soil tillage on maize was investigated at the Experimental Station of the Lithuanian University of Agriculture in a silty loam Luvisol during the period of 2010. The aim of the experiment was to establish the influence of reduced soil tillage intensity on maize morphometric and productivity parameters. Treatments of the experiment; 1. conventional (23-25 cm) ploughing with a mouldboard plough (1A); 2. shallow (12- 15 cm) ploughing wit a mouldboard plough (SA); 3. deep (25-30 cm) loosening with a chisel cultivator (GP); 4. shallow (12-15 cm) loosening with a disc harrow (SP); 5. zero tillage (ND). The reducing of primary soil tillage had no significant negative influence on maize crop density, grain yield and mass of 1000 kernels. The highest yield of grain was observed in ND (2.90 t ha'1). Similar tendency is observed in the case of 1000 kernels mass. Significantly the largest yield of maize canopy dry biomass was established in the no-tilled soil, lowest - in deep loosened soil
