The influence of nitrogen and sulphur fertilisation oil yield and quality was Studied in two ecotypes of friarielli (Brassica rapa L. subsp. sylvestris L. Janch. var. esculenta Hort.) grown in a floating system. In the first experiment, we assessed the effects of different levels of N fertilisation on friarielli yield. In a second experiment, we tested three concentrations of S in the nutrient solution [2.6 mM, 4.0 mM, and 8.5 mM; corresponding to N:S concentration ratios of 10:1. 6.5:1, and 3:1. respectively] with the objective of fine-tuning the nutritional requirements for N and S to optimise both friarielli yield and quality The main findings can be summarised as follows: (i) friarielli call be grown efficiently in a hydroponic system: (ii) both yield and quality in friarielli are strongly dependent oil the N:S ratio, of the nutrient solution: (iii) S may affect shoot nitrate accumulation in response to N availability: (iv) the response to S fertilisation is genotype-specific; (v) the anti-oxidant capacity of shoots increases with increasing S concentrations in the nutrient solution; and (vi) 26 mM N and an N:S concentration ratio of 10:1 in the nutrient solution are Suggested for the best performance of hydroponically-grown friarielli.
