INFLUENCE OF PREDECESSORS AND TECH-NOLOGIES OF PROCESSING ON DEVELOP-MENT OF WEEDS
DescriptionIssues related to the contamination of crops are topical and very relevant. All this fully applies to the main crop produced in the South of Russia – winter wheat. In this regard, the presented results of studies of the influence of predecessors and tillage technologies on the development of weeds in the cultivation of winter wheat are relevant. Experimental studies were carried out in conditions of many years of experience located in the FEDERAL state scientific institution «ANTS «Donskoy». The influence of different methods of sowing (ordinary, scattered, belt) and technologies of tillage (dumping, non-dumping, surface, small) on infestation of winter wheat is considered. It is established that the least amount of weed plants is provided at scattered sowing on the background of deep tillage. The main treatment at a depth of 18-20 cm reduces the number of weeds by 47% in comparison with the surface (8-10 cm), and the scattered sowing reduces their number by 80%, since weeds are in more severe conditions compared to winter wheat, the rapid development of which contributes to the optimal nutrition area. Of the predecessors, the most acceptable is the steam with the number of weeds 7-25 PCs / m2, which is several times less than after peas, or corn after silage
