Abstract
The article focuses on the research results concerning the effect of long-term application of basic tillage systems and fertilizing on weed component quantitative indicators of Sinapis Alba agrophytocenosis. The research was being conducted in four-field crop rotation of the stationary experiment under conditions of Right-Bank Forest-Steppe of Ukraine during 2009–2016. It has been proved that the application of subsoil system of basic tillage results in 67% increase of weed quantity in case of mineral fertilizing and 207% in case of organic-mineral fertilizing as compared to conventional tillage. Weed vegetative wet weight increases by 69 % with mineral fertilizing and by 52% with organic-mineral fertilizing in case of subsoil tillage in comparison with conventional tillage. Mineral fertilizing decreases vegetative wet weight and total amount of weeds by 12 and 40% respectively in comparison with organic-mineral fertilizing system. 14 species of weeds have been found in Sinapis Alba agrophytocenosis, among them the dominant ones are Setariaglauca L., Chenopodiumalbum L., Capsella bursa-pastoris (L.) Medik., GalinsogaparvifloraCav., Amaranthusretroflexus L. The quantity of weed species increases with organic-mineral fertilizing and mineral fertilizing by 18 and 20% respectively in case of subsoil tillage as compared to conventional tillage. The quantity of perennial and wintering weed species increases in Sinapis Alba sowings with organic-mineral fertilizing and mineral fertilizing in case of subsoil tillage. The most favorable phytosanitary state of Sinapis Alba agrophytocenosis with mineral and organic-mineral fertilizing occurs in case of conventional tillage which includes stubble disking of previous crop to a depth of 10 to 12 centimetres immediately after cropping and ploughing in 10–12 days to a depth of 25 to 27centimetres.
