Assessment of the ecological reaction of agrocenosis during monitoring observations of the production process of cereals

The existing problems of climate change: an increase in the number of negative natural phenomena (droughts, floods); rising temperatures and energy use; increasing dependence on food imports. Adaptive crop production and the sustainability of agrocenoses in general requires an assessment of crop variability and has an important independent significance. In this work, a comprehensive assessment of the production process of spring barley in the conditions of microfield experience with the use of various types of fertilizers was carried out, as well as an assessment of the emission of nitrous oxide (N2O) in the crops of the studied crop by phenophases, depending on the time dynamics of environmental factors.
