Abstract
Minimum tillage, as an important element of the sustainable functioning of the agroecosystem, can lead to an increase in weeds in crops, especially when fertilizers are applied and the use of herbicides is reduced. This paper dwells on analyzes the results obtained during 2015-2018 on a long-term three-factor field experience, which included 4 gradations of tillage: moldboard plowing (MP), surface treatment with deep loosening (STL), surface-ploughing treatment (SP) and surface treatment (ST); 6 gradations of fertilizers: No fertilizers (F0), nitrogen (N), straw (S) straw + nitrogen (SN), straw + NPK (SNPK) NPK (NPK); 2 gradations of herbicides: Without herbicides (G0), With herbicides (WG). Our studies indicate that there is no significant effect of tillage on the number and dry weight of weeds. The positive effect of SP and SNPK on reducing the number and weight of perennial weeds and obtaining the highest yield has been established.
