What we have in the present paper are the results of analysis on how the amount of precipitation, temperature, type of soil, and drip irrigation can affect celeriac root yield. The soil type had a considerable influence on yield. In both study years concerning two ways of growing - watering and dry cultivation, the celeriac root yield was higher on the chernozem soil type. The higher amount of precipitation and higher temperature during the period of vegetation resulted in higher root yield the first study year (both locality and dry cultivation). Compared with in dry cultivation, in both study years as well as both localities, drip irrigation had higher effects on celeriac root yield.
