The effect of differentiated nutrition on the content of antioxidants in broccoli

Popis výsledku v původním jazyce

The aim of this work is to determine the impact of differentiated nutrition, using different rates of nitrogen and sulphur, on the level of antioxidants, particularly vitamin E1 (alfa-tocopherol), vitamin C and beta-carotene in the broccoli rosette. Theexperimental broccoli variety was Tiburon F1. In the 3-year field trial we observed the effects of different rates of nitrogen and sulphur on the amount of antioxidant compounds in broccoli. The experiment consisted of four fertilisation treatments: 1) unfertilised control; 2) fertilised with 200 kg N.ha-1; 3) also fertilized with 200 kg N.ha-1 and supplemented with 50 kg S.ha-1; 4) 200 kg.ha-1 and 60 kg S.ha-1 was applied. To determine the amount of beta-carotene and vitamin E1, the slightly modified method of Olives Barb et al. (2006) was used. The vitamin C content was determined by titration. Nitrogen nutrition has a significant impact not only on the amount of harvested broccoli, but also on the content of beta-carotene, vitamin C
