Effect of Fertilization with Digestate Supplemented with Sulphur on Yields and Quality of Kohlrabi
Original language description
In a one-year vegetation pot experiment we compared the effect of the digestate from a biogas plant to digestate supplemented by S-mineral fertilisers on yield and quality parameters of kohlrabi, variety Moravia. Three treatments were used in the trial: 1) untreated control, 2) digestate, 3) digestate + S. The rate of N was the same in treatments 2-3, i.e. 1.5 g N/pot. The weight of single kohlrabi bulbs in the unfertilised control was significantly lower (46.9%) than in the digestate treatment (100%). Digestate supplemented by sulphur (treatment 3) significantly increased the bulb yield (109.7%) against the pure digestate - treatment 2 (100%). The content of ascorbic acid did not differ between all treatments (311-329 mg/kg). There were significant differences between all treatments (1-2-3) in bulb nitrate content (163-509-455 mg NO3-/kg fresh matter, respectively). After digestate + S application the nitrate content decreased significantly compared to pure digestate treatment. We recommend the use of digestate supplemented by S-mineral fertilisers to kohlrabi as it results in comparable or better yield and qualitative parameters of kohlrabi compared with digestate only.
