The paper discusses the economic efficiency of sulphur fertilization on the yield of ryegrasses cultivated in monoculture and in a mixture with white clover. Two levels of nitrogen fertilization were used in doses of 50 and 100 kg N•ha-1 and two sulphur fertilizers, Arysta siarka and Pro-siarka in doses of 5, 10, 15 kg S•ha-1. The research shows that sulphur fertilization was profitable and economically effective. It was found that the combination of sulphur fertilization with nitrogen fertilization may result in significant yield increase. The effects of sulphur fertilizers adopted for research differed despite the same parameters. Arysta siarka fertilizer produced the most effective production and economic results if the 10 kg S∙ha-1 dosage was used regardless of the nitrogen fertilization level whereas Pro-siarka fertilizer (15 kg S∙ha-1 dosage) produced the highest yield in regard of grass plants. In the case of the mixture of grass and white clover, the highest yield was produced also in regard of the 15 kg S∙ha-1dosage in combination with the nitrogen fertilization of 50 kg N•ha-1. The increase of nitrogen fertilization up to 100 kg, however, led to the decline in the effectiveness of sulphur fertilization.
