One field trail was carried out in Żydowo in 2015-2016. The cultivation profitability of the five sugar beet varieties tolerant to pest compered to average profitability of three varieties without tolerance was assessed. The number of living eggs and larvae of Heterodera schachtii in field soil was below the harm threshold. The results showed that the cultivation of new tolerant sugar beet varieties on a bed of low pest pressure compared to varieties without tolerance was highly profitable. It was found that the additional cost incurred for the purchase of tolerant varieties in 2015 turned from 4.0 to 7.4 times depending on the variety, whereas in 2016 from 8.4 to 35.3 times, respectively.
