Abstract: The long-term experiment was performed at the Experimental Station of the Aleksandras Stulginskis University in 2014. The soil of the experimental site was silty light loam (Endohypogleyic-Eutric Planosol (PLe-gln-w). The aim of the long-term experiment was to determine the influence of reduced different primary soil tillage on maize biometric and productivity parameters. Treatments of the experiment: 1. conventional (23-25 cm) ploughing with a mouldboard plough (IA); 2) shallow (12–15 cm) ploughing with a mouldboard plough (SA), 3) deep (25–30 cm) tillage with a chisel cultivator (GP), 4) shallow (10–12 cm) tillage with a disc harrow (SP), 5) no-till (ND). Different methods of soil tillage had no essential effect on the biometric parameters of maize. The research showed that conventional ploughing, shallow ploughing, deep loosening, shallow loosening and zero tillage did not have great significance of the results obtained. The lowest mass of 1,000 grains was identified in deeply and shallowly loosened plots. The yield of grain varied from 7.25 t ha-1 to 5.52 t ha-1; consequently, no higher differences came up between the options. Different methods of soil tillage had no significant influence to the biomasses of steams and leaves, and cobs
