Description
| - 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. The experimental 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 and vitamin E1. The average content of beta-carotene ranged from 24.84 mg.kg-1 to 30.13 mg.kg-1 of fresh mass. The content of beta-carotene in broccoli rosettes increased as per the following order of treatments: control > N:S (200:50 kg.ha-1) > N:S (200:60 kg.ha-1) > N (kg.ha-1). The beta-carotene content increased significantly only in treatment 2 as compared to all the other treatments. The level of vitamin C revealed the significant effect of fertilisation in all the treatments in contrast to the control variant. What is more, in treatment 4 the content of vitamin C increased significantly in contrast to fertilised treatments 2 and 3. The average content of vitamin E1 ranged from 4.33 mg.kg-1 to 4.88 mg.kg-1 of fresh mass. There were no significant differences among the untreated control and fertilised treatments 2 and 3. The only significant decrease in the content of vitamin E1 was detected in treatment 4 as against the unfertilised treatment 1.
