A field experiment was performed at the Experimental Station of the Aleksandras Stulginskis University in 2015. The soil of the experimental site was silty light loam Endohypogleyic-Eutric Planosol (PLe-gln-w). The aim of the experiment was to ascertain the influence of reduced different primary soil tillage on maize biometric and productivity parameters. The soil was: 1) conventionally (23–25 cm) ploughed with a mouldboard plough (IA), 2) shallowly (12–15 cm) ploughed with a mouldboard plough (SA), 3) deeply (23–25 cm) tilled with a chisel cultivator (GP), 4) shallowly (12–15 cm) tilled with a disc harrow (SP, 5) not-tilled (ND). Different tillage had no significant impact on morphometric indicators of maize. In no tilled soil, maize had slightly better productivity parameters then shallowly ploughed (SA), deeply tilled (GP), shallowly tilled (SP), but wasn’t better then conventionally ploughed (IA).
