The basis of the study was a three-year long field experiment, carried out on degraded Phaeozems, IIIb soil valuation class, with neutral pH and low richness in assimilable sulphur. Winter rapeseed cultivar Star was grown. The experiment was set up as a split-block design with two factors (n = 2): the first factor was nitrogen dose (in kg·haˉ¹: 0, 60, 120, and 180), and the second factor was sulphur dose (in kg·haˉ¹: 0, 20, and 60). An additional study aspect was diversification of methods and dates of sulphur application (pre-sowing: in-soil and top-dressing: as foliar fertilizer). For plants unfertilized with sulphur, dose of 120 kg N·haˉ¹ was the most effective in regards to yield-formation, and for plants unfertilized with nitrogen, dose of 20 kg S·haˉ¹. In-soil application of sulphur made it possible to obtain higher grain and protein yield than its foliar application. Including sulphur in nitrogen fertilization made it possible to obtain significantly higher yield of spring rapeseed grain, and also protein content and yield, in particular in the conditions of in-soil sulphur application.
