e0“The introduction of high doses of mineral fertilizers and the use of herbicides in the integrated crop protection system of grain-grass-row crop rotation led to a decrease in the harmfulness of weeds.”
e1“Yield losses from the total value of the raw phytomass of weeds amounted to 15.75 c/ha (5.3%) and 2.51 c/ha (1%)”
e2“Under the influence of mineral fertilizers, the hazard coefficients decreased by 2.6 and 5.7 times”
