Abstract
In this research, we investigated the comparative analysis of weeds species composition in the crops of spring soft wheat cultivated using organic and intensive technologies (on the example of Altai Krai) in 2019-2020. On average, over two years, the intensive technology of growing spring wheat has shown better results than the organic one. So, weediness in crops with organic technology was 4 times higher than with intensive technology. Annual monocotyledonous prevailed 133.2 psc/m2 (organic technology), with intensive technology there were 98.4 psc/m2 less. Without the use of chemicals for plant protection and fertilization, in our experience, not only there were more weeds, but this directly influenced the yield of this crop.
