Features of the structure and spread of the root system of wild species of legumes and their reaction to the level of groundwater

Abstract

Improving the feed base in the North-West region is a priority for providing farm animals with complete feeds. Perennial legumes contain nutrients that are necessary to increase the productivity of farm animals and adapted to the soil and climatic conditions of the region. Legume plants in the composition of grass mixtures form high and stable yields, are characterized by intensive growth rates after the next alienation, and are resistant to intensive hay or pasture use. Each plant species has different requirements for the biological characteristics of growth and development to the growing conditions, therefore, monitoring of species is relevant for their further conservation. For the successful realization of the potential capabilities of perennial leguminous plants, it is necessary to effectively use their gene pool of wild and cultivated species that grow in the flora of the Novgorod region. The article studies the biological and economic properties and characterizes perennial leguminous plants for cultivation in the North-West region of Russia. Laws of transformation of matter and energy within the agrogeosystem and methods for their improvement. Plant communities were identified in which perennial leguminous plants grow, which have selection value as a source material for selection. The structural features of root systems, the reaction to the groundwater level were studied, and their ecological plasticity was revealed.
