In 1994 field trials were carried out to study the impact of weediness and weeding on the amount and structure of potato species "Sulev" yield. Weeds were removed by cutting. The climatic and agrotechnical conditions of the trials are described. The results of the trials were analysed. The average indices demonstrated that weeding did not have any impact on the number of tubers, it was rather modest. The results of the research were influenced by increased weight of tubers. The yield srtucture and the dynamics of tuber number were more influenced by the use of chemicals than by weeding.
