Abstract: Long-term field experiment was established in 1966 in the Experimental station of Aleksandras Stulginskis University. This paper presents productivity data of winter and spring cereals in 2015 - 2017 from this long-term field experiment. Winter wheat, winter rye and spring barley was grown in 9 different crop rotations arranged in tame and space as well as rye monocrop were included. Soil - Calc(ar)i-Endohypogleyic Luvisol. The highest winter rye productivity results were obtained while rye growing after manuring in grassland and fallow crop rotation sequences. Notwithstanding winter rye is not sensitive to preceding crop, majority of cases showed lower productivity of rye yield in a fifty years term rye monocrop to compare with crop rotation. In our experiment the biggest effect on rye productivity elements obtained from preceding crop and from total rainfall and temperature on grain formation time. The correlation between these indices was significantly strong. Winter wheat is more sensitive to preceding crop, the influence of crop rotation was significant in all years of these experiment. The best preceding crop for wheat was vetch-oat mixture fertilized with animal manure in cereal crop rotation. Spring barley were not so demanding to preceding crop, they can be grown after winter cereals. However their productivity was higher in row sequence or in case of animal manure application during crop rotation
