Impact of agricultural landscape conditions on botanical composition of legume-bluegrass mixtures: An analytical system of monitoring the state of agrocenoses

Sustainability of agricultural landscape is affected by agricultural developments as well as various forms of urbanisation. The most important criterion for the rational distribution of cultivated crops in land use is the compliance of their biological requirements with the soil and environmental conditions of the habitat. Based on this, a study was conducted in the Upper Volga regions for adaptive reactions of legume-bluegrass mixtures on agricultural landscape terrain regions. Regression of the botanical composition of legume-bluegrass grass stands with agricultural landscape conditions showed changes depending on the exposure of the slope, and the strength of the influence of agroecological factors scrutinized. According to the assessment, agroecological factors revealed the formation of a stable agrocenosis of perennial herbs. Since individual agricultural landscapes differ in the nature of the distribution of matter and energy, the developed general recommendations for the cultivation of perennial grasses require adaptation to the soil and climatic features of specific regions. From the data analysis, the identified patterns can be used in developing digital models for intensive crop production in different soil and climatic zones. © 2020, Gaurav Society of Agricultural Research Information Centre.
