Abstract


The present research work indicates that a combination of cultural practices and appropriate herbicides usually gives the most effective weed control. Field experiments were carried out in the years 2015-2016 to the National Institute of Research and Development for Potato and Sugar Beet – Brasov, Romania Our aim was to evaluate the efficacy of the herbicides metribuzin and metobromuron, applied at different rates, in the pre-emergence condition and to establish yield and quality characteristics of Brasovia variety. No phytotoxic symptoms and no differences in crop vigour were observed on any plots. From the results obtained it is evident that treatments enhaced the yield. In untreated plots the yield is significant lower (27.0 t/ha) than where were applied treatments (66.0 t/ha). Herbicide rates must be adjusted for soil texture, percentage of organic matter, soil pH, weed species and potential for soil residue.
