The influence of a nitrogen fertilisation and variety on the nitrates ‘Content of in the roots’s swellings of a celeriac after harvest and storage

University of Warmia and MazuryAbstract
Series of experiments were carried out on 5 varieties of a root celery in order to evaluate the content of nitrates in the root’s swellings – after harvest and storage (the method of colorimeter was used). The investigations revealed that the content of nitrates in the root’s swellings was increasing accordingly to growing doses of N – fertilisation. It was stated that some impact on the increase mentioned had also genotype of tested varieties. No peculiar susceptibility of the root celery to accumulate nitrogen compounds was observed, during the experiments.
