Trials were carried out in 1975-76 on a derno-podzolic sandy loam soil with the early potato Priekul'skii Rannii and with the maincrop potato Gatchinskii; normal rates of mineral fertilizer (60 kg N, 90 kg P2O5 and 60 kg K2O) and double these rates were applied. Prometryne at 2 kg and linuron at 3 kg/ha were applied pre-em. at normal rates and at double these rates. Herbicides did not impair tuber quality or adversely affect the nutrient content of the tubers.
