The analysis of literary sources revealed the problems of the development of organic agriculture, the development of environmentally friendly technologies for growing leguminous crops, the expansion of areas of cultivation of high-protein legumes and the study of their impact on soil fertility, improvement of its condition and conservation in general in the face of climate change. Grain legumes, as well as cereals, have been found to be a staple food for most of the world's population, especially in developing countries. In Ukraine, crop data have become strategic and important by overcoming the problem of providing the animal feed to the feed protein. They cover 16% of humanity's need for protein. The reserves of increasing the efficiency of using modern varieties of leguminous crops, aimed at increasing their yield and quality, saving material and technical and energy resources, have been evaluated. It is proved that in this plan it is important to search for selection of scientifically-proven varietal legume cultivation technology for different zones using microbiological fertilizers and growth of stimulating nature allowed for use, in order to preserve soil fertility, improve its physical and chemical properties, and stabilize its granulometric properties. Soil microbiota. The national varieties listed in the State Register of Plant Varieties of Ukraine as a factor of increasing competitive agriculture and adapting them to organic varietal technologies of growing leguminous crops are subject to study. The article identifies the varietal diversity of genetic support for a fundamentally new source material of leading leguminous crops. The problematic of the scientific article has a complex multidisciplinary character in the combination of adaptive farming systems and varietal cultivation technology in view of current trends in climate change. Installation and implementation are based on the problems, as well as the tasks of applied research, which is performed at the expense of the state budget fund on the theme: «Development of methods for improving the technology of growing leguminous crops using biofertilizers, bacterial preparations, extracurricular nutrition and physical nutrition» Vinnytsia National Agrarian University.
Key words: legumes, variety, technological methods, cultivation area, use cases.
