The effect of no-tillage cultivation system and soil mulching with cover crops (white mustard, spring vetch, tansy phacelia, oats) on weed infestation, yielding of onion and carrot was studied. Species composition and number of weeds on onion and carrot plantations were estimated. Annual weed species: Matricaria chamomilla L., Senecio vulgaris L., Galinsoga parviflora Cav., Urtica urens L., and Chenopodium album L. dominated in primary weed infestation on plots with onion and carrot. Application of plant mulches and conventional tillage limited weed infestation of vegetables. A significant increase in weeds number was noticed in objects without plant mulches on onion and carrot plantations. The total and marketable yield of onion was highest under conditions created by no-tillage cultivation system. A higher yield of carrot roots was harvested from objects with conventional tillage.
