20.500.12556/RUL-135747 Nitrogen and sulphur fertilisation for marketable yields of cabbage (Brassica oleracea L. var. Capitata), leaf nitrate and glucosinolates and nitrogen losses studied in a field experiment in Central Slovenia A field trial of white cabbage (Brassica oleracea var. Capitata L.) was carried out under the humid temperate climate conditions in Central Slovenia to investigate the effects of calcium ammonium nitrate (0, 180 and 240 kg N ha$^{−1}$) and gypsum (0 and 40 kg S ha$^{−1}$) fertilisation on yield, yield quality (nitrate, glucosinolate levels and glucosinolate profile) and nitrogen use efficiency. The highest marketable yield, dry matter yield and nitrogen uptake were obtained at the highest nitrogen fertilisation rate when in combination with sulphur. For this treatment, the nitrogen surplus in the soil after harvesting was lower than for the same nitrogen fertilisation without sulphur application. For the combination N$_{240}$S$_{40}$, the sulphur addition significantly increased nitrogen use efficiency, which resulted in reduced nitrate content in the cabbage heads. The chemical forms of glucosinolates showed that 80–85% were aliphatic glucosinolates with the remainder as the indole group. For the aliphatic glucosinolates, significant interactions between nitrogen and sulphur fertilisations were reflected in increased levels of progoitrin and glucoiberin when sulphur was applied at the lower nitrogen fertilisation rates. For the indole group, the levels of glucobrassicin and the indole group itself decreased at higher nitrogen fertilisation rates, independent of sulphur fertilisation. cabbage cultivation nitrogen and sulphur fertilisation nitrate content glucosinolates profile nitrogen surplus belo zelje Brassica oleracea var. capitata gnojenje dušična gnojila žveplo nitrati kemična sestava glukozinolati true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-30 11:46:36 2022-03-30 11:46:37 2022-09-14 04:14:58 0000-00-00 00:00:00 2021 0 0 16 str. iss. 7, art. 1304 Vol. 10 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 635 2223-7747 10.3390/plants10071304 68288771 RAZ_Kacjan-Marsic_Nina_2021.pdf RAZ_Kacjan-Marsic_Nina_2021.pdf 1 1978B7A5FE1B098B46A80E779EFB4226 74c7ebfcb974911c8bea698c7c4f8b22559901955ea99551d9be710e7dd16180 bddff4a9-b00e-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155019 https://www.mdpi.com/2223-7747/10/7/1304 1 461ddb95-b00e-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155018 Biotehniška fakulteta 0 0 0
