Abstract: The long-term field experiment (since 1988) was carried out at the Experimental Station of the Vytautas Magnus University Agriculture Academy (VDU ŽŪA, 54º52′ N, 23º49′ E). The soil of the experiment is silty light loam Planosol (Endohypogleyic-Eutric, PLe-gln-w). Since 1988 wheat, barley, rape, beet and maize crops were investigated applying five different tillage treatments: 1) conventional (22–25 cm) ploughing by a mouldboard plough, 2) shallow (12–15 cm) ploughing by a mouldboard plough, 3) deep (25–30 cm) loosening by a chisel cultivator, 4) shallow (10– 12 cm) tillage by a disc harrow and 5) no-till. The aim of the experiment was to investigate the influence of primary soil tillage of different intensity on faba bean productivity parameters. Investigation results show that the tillage methods of different intensity had significant effect on crop density before harvesting. Crop density before harvesting was significantly 19.7 % higher when shallow loosening was applied as compared with that when deep ploughing was used. Canopy dry mass productivity was the highest deep loosening was applied as compared with other tillage methods. Canopy dry mass productivity was the slightest when shallow loosening was applied as compared with other tillage methods. Weight of 1000 grain was significantly 20.6 % higher when direct seeding was applied as compared with deep ploughing. Protein content of grain was the highest when shallow loosening was applied as compared with other tillage methods. Protein content of grain was the lowest when deep loosening was applied as compared with other tillage methods. The tillage methods of different intensity did not have significant effect on the canopy dry mass productivity, the grain yield and grain protein content
