The results of the agriculture systems impact of on sugar beet agrophytocenosis weeds studies has been presents. The studies were conducted in the field experiment of the Agriculture and herbology department (Agronomic Research Station of the National University of Life and Environmental Sciences of Ukraine), which is located in the ForestSteppe of Ukraine. The studies were performed in a five-track rotation with the following alternation of crops: peaswinter wheat-sugar beet-barley-corn for grain. Three variants of intensive, ecological and biological agriculture systems have been studied. Within each system of agriculture, was studied four variants of basic tillage in crop rotation: differentiated (control), subsurface, periodical moldboard (shelf+shelf-free), reduced (surface). Laboratory and field studies the impact of agriculrure systems on the crop weediness degree and formation of agrophytocenosis weed component have been determined. An intensive and ecological agriculture system has been found to be a favorable option, which has significantly reduced the number and weight of weeds. The use periodical moldboard (shelf+shelf-free) tillage helps to reduce weeds compared to differentiated tillage.
