Researches, which have lasted for two years, were carried out on long-term trial field at Rimski Šančevi, Novi Sad, Serbia. In this trial, the eight fertilization variants of N, P₂O₅ and K₂O increased amounts were studied. Sugar beet root and tops yields were determined, as well as the elements of technological sugar beet root quality. Based on these results, percentage of sugar utilization and refined sugar yield was defined.

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).

The effect of a considerable number of both domestic and foreign sugar beet genotypes on root yield and quality was investigated. The data demonstrated the most favorable results of some genotypes for root yield and sugar content. Trials were conducted on rhizomania infested soil, thus tolerant genotypes were used. Susceptible cultivars represented the control. In the trial root yield was high and sugar content low. On average, in the genotypes tested, root yield varied from 73.98 to 93.30 t/ha and sugar content from 11.90 to 13.36%, depending on weather conditions.
