Abstract

Goal. To determine the species and quantitative composition of weeds, the influence of individual precursors on the rate of development of agrophytocenoses in winter wheat crops, taking into account the influence of modern agrotechnological methods on the degree of weediness of production crops.

Methods. During 2017—2019 studied agrophytocenoses under production conditions for winter wheat, depending on predecessors and agrotechnological techniques. Weeds were counted and calculated in accordance with generally accepted methods for assessing the number and distribution of segetal vegetation, taking into account morphological features and their clear classification.

Results. The most numerous were cereal millet weeds, represented mainly by two species — common blackberry and green bristle. Among the dicotyledonous spring weeds, the most numerous were the medicinal smoky and the highlander bindweed, among the wintering weeds — the field violet and field cocci. In recent years, sunflower has taken a significant place in the structure of cultivated areas of the region. Therefore, the sunflower scavenger has become a very serious polluter of winter fields, which in its harmfulness exceeds most weeds.

Conclusion. Analysis of agrophytocenoses in winter wheat crops in the context of individual predecessors showed that the number of weeds in the fields of steam wheat is almost 2—2.5 times less than after corn or sunflower.
